How to increase the power of a VAZ 2109 carburetor generator

Engine tuning VAZ 2109

As a rule, engine tuning on the VAZ 2109 is carried out by car owners interested in enhancing the power and dynamics of their vehicle. VAZ 2109 engine tuning is a unique opportunity to improve the technical characteristics of your car.

VAZ 2109 carburetor engine tuning

Note. Checking and upgrading the brakes and gearbox is a classic start to tuning. After these components are finalized, the actual process of tuning the engine begins.

Timing device VAZ 2110 injector 8 valves

Many people are concerned about the question: Do the valves on the VAZ 2110 injection engine bend? No, it doesn’t bend, the 8-valve injector does not suffer from this defect. But this does not mean that you should not monitor the timing belt. Since loosening and subsequent jumping of the belt by a certain number of teeth will lead to inevitable problems

It is worth paying special attention if engine oil gets on the belt; an oiled belt will not last long. Below is a detailed image of the timing diagram of the 8-valve injection engine "tens"

See the photo below.

When replacing the timing belt on a VAZ-2110, it is necessary to clearly align the marks on the camshaft and crankshaft pulleys; without this, the engine will not operate normally. Another important point is that when the tension roller moves to its original state, the marks shift as the belt tension changes. Therefore, carefully check whether the timing marks are clearly aligned before putting on the cover covering the timing belt.

Crankshaft replacement

If you install a different crankshaft on the “nine” (with a larger crank radius), you can achieve a high piston stroke. Accordingly, the cylinder volume will be larger (that is, the engine will become more powerful). In this case, the VAZ-2109 will not “eat” more fuel, and its dynamics will increase significantly.

True, this is a more expensive method than boring a cylinder block. Among the new parts that need to be purchased for this work, the following should be highlighted:

New crankshaft. The diameter of its crank must be from 75 to 80 millimeters.

Set of new pistons. You should choose those that will best fit the purchased crankshaft

It is important to consider that the cylinder block has its own maximum height and a very large piston will not work in it.

Piston rings (compression and oil scraper set).

In addition, you need to find a master who will carry out the work of boring the block for a given set of pistons. In terms of time, the entire engine tuning (VAZ-2109-21099) can take from 1 to 3-4 weeks.

Installing a motor from a foreign car

What engine can be installed on a VAZ-2109 from a foreign car? This question is very difficult, since there is no single answer to it. Some motorists advise installing an engine from German Audis and Volkswagens from the 90s. But one of the most suitable options is to install an engine from an Opel Vectra.

However, no matter what this engine is, it is better to mount it with the original gearbox. And these are additional costs, and to a greater extent from the financial side. Plus, you will have to enter the new motor into the registration certificate.

Where to start?

Let's look under the hood of the car and, through easy inferences, figure out the involvement of the motor in this story. The engine is the “heart” of any car, and the investigation should begin with it. The plant for the production of serial models equips a typical VAZ 2109 with a carburetor with a capacity of 1.5 liters, which gives the chance to extract approximately 70 horsepower from the engine shaft.

Not much, not little, but quite enough for an ordinary trip around the city. But if you are not satisfied with the usual driving with the breeze, and your heart, as in the song of the same name, requires “change” and you want something tougher, you will have to think about tuning and improving this part. There are options for buying another car, changing the engine, but who needs this extra hassle, not to mention the financial component of this issue. If we had millions, would such topics about car tuning and engine changes even begin to open? Everyone would have been driving around the city in brand new Audis long ago, and the problem of changing equipment would have disappeared by itself.

Let's get back to the heart of the matter. As you may have already guessed, one of the best options to increase acceleration is to change the carburetor, or, well, modernize it, whichever is more convenient for you

It is also worth paying attention to changing the cam shaft in order to increase the intake-exhaust time of the air-fuel mixture, which is achieved by a different form of cams on this same shaft

Everyone knows that factory production “saves” on car parameters because of the damned GOST standards that are imposed on them. But we are not a factory and we are not aware of all these artificially created restrictions, and therefore we have every right to dispose of our car the way we want. For this reason, we are unlikely to harm anyone by installing a new high-quality filter

There are, however, a number of disadvantages, for example, the abandonment of a standard filter, the future fate of which remains a mystery to everyone, or an increase in noise level, but we do not think that this will have a significant effect, so we will not focus much attention on this

There is also an alternative option for installing an additional injection system, but in this case it is necessary to abandon the car body, and there is not much space left for the filter, which is also a significant disadvantage. We have to pay for everything in our lives, and while improving one parameter, we must be prepared for the deterioration of another. The average cost of this “homemade product” will cost the buyer about 100-150 dollars, but the engine power will pleasantly please thanks to an increase of 5% from its previous performance.

Don't forget about other parts of the car

As mentioned above, the clutch suffers the most, and, naturally, it should also be changed. Some people like to use regular imported kits, while others, more advanced ones, like cermets. The last “patient” in this whole scheme is the CV joints, which, as the engine power increases, will have to be paid attention to very often, right up to replacement. The brake pads will also not be completely “happy” with the new operating conditions. Installing axle shafts will provide some help in this matter, but if you constantly squeeze full power out of your “horse,” then their usefulness will not last long. The new engine will not be happy with the old suspensions, which are already accustomed to a small work front. The difficulty in maintaining the center of gravity, especially when turning, will make itself felt in the near future.

Springs of Western counterparts will come to the rescue, and replacing gas “one-tube” ones will save the car from an unpleasant fate. True, you will have to press yourself a little to the ground, but the system will quickly respond to the slightest vibrations of the steering wheel in any direction.

Paying so much attention to speed characteristics that allow us to stay afloat, we completely forgot about the brakes. It is very difficult to overestimate the importance of these “guys”, especially when you are driving at breakneck speed, with countless horses under the hood. Fortunately, here too there are alternative options from the older brother of the “nine” VAZ 2112. The brake pads of the improved friend will satisfy the requirements of the new internal combustion engine in terms of strength and quality characteristics, but the price will make you pleasantly surprised, because it is almost identical to the old pads.

That’s probably all, after all the above actions, only the body will remain old from your old car, and even that can be modernized - if you wish!

Methods for tuning the power unit

There are many ways to improve engine performance. Before work, keep in mind that in case of an error you will have to completely change the unit. Each method of changing motor characteristics has its own advantages and disadvantages. Here are a few relatively safe tuning methods:

1. Installing a zero resistance filter. Craftsmen often call this component “zero”. If you choose the right filter, the dynamic performance and motor power will increase by 5%. If you equip your car with a zero drive, then you will have to carefully monitor it and clean it in a timely manner. Otherwise, installing the element will be pointless and dangerous. A dirty filter poses a risk of engine damage. Focus on a price of 5 to 6 thousand rubles per filter. Instances that cost less will not work normally.
2. Together with injection power units, it is often recommended to use direct-flow mufflers. This part should only be used in the gas exhaust system if you have carried out a thorough modernization of the engine. Another option when such a muffler would be appropriate: if the car has a turbo air injection system (additional compressor). The straight-through muffler will only affect power in conjunction with other upgrades. In other cases, installing it is a pointless waste of money. It will make the car noisier and a roar will be heard when driving.
3. Another effective way to increase engine power is to install a sports range on the gearbox. At the same time, a 6th gear will be added, and the car will accelerate more dynamically due to a change in a number of gear ratios. The overall engine power will not change, but the dynamic characteristics will become noticeably better. At the same time, replace the piston group and install a more powerful engine. Deep reworking of the engine and gearbox will allow for a qualitative change in the power plant. You will feel the dynamics already when you first start the engine and accelerate. Such tuning will be expensive, but it will be worth it.
4. Chip tuning is most often recommended for injectors. Using a simple laptop, a small amount of equipment and application programs, the ECU is configured. The advantage of this method is its low cost - you do not have to carry out mechanical work or interfere with the elements of the unit. If you make a mistake, it will be enough to replace the on-board computer. It will cost less than replacing an engine if another type of tuning fails. After flashing the ECU, you will immediately notice a change in engine performance.

Modification Basics

The goal of any changes is to increase power and improve dynamic performance. The tuning unit becomes more durable. The concept of high-quality modernization includes the installation of updated elements:

• cylinder head;
• sports receiver;
• intercooler or turbine;
• camshaft;
• piston group.

In the process of working on the cylinder head, the shape and diameter of the intake valves and combustion chamber change. Often, the VAZ-2109 is equipped with spare parts from other cars, for example, an additional carburetor and manifold, which are taken from the Oka. Such a modification is not possible if your VAZ-2109 has an injection model of the power plant.

The carburetor VAZ-2109 models have only one advantage - the power unit is capable of running on low-octane gasoline. It is a little easier to repair than the injector. You should not radically change the power unit if you have a carburetor type - modify it rather than install a new injector. Such a change is very costly in terms of finances and does not justify itself. It is better to use other methods of modernization.

Boosting methods

In most cases, achieving the required indicators is achieved by increasing the volume of the car engine. To accomplish a task of this kind, there are several options:

The first involves increasing the diameter of the cylinder block to accommodate a larger piston diameter by boring. It is called “folk” because of its low cost, because in this case all that requires expenses is the purchase of a set of pistons and wheels, as well as payment for turning services.

The first option is boring

The second is to replace the factory crankshaft with one that has a larger crank radius and therefore a larger piston stroke and larger volume. Its cost is much higher than the first method, since you will have to spend money on a crankshaft, a set of pistons suitable for the new crankshaft (since the height of the cylinder block has certain restrictions), and special rings for the pistons. In addition, it will be necessary to pay for work related to block boring.

Example for replacing a stock crankshaft

For many, it may be surprising that the increased displacement of the “nine” engine is not always the most advantageous method of boosting. In some situations (it all depends on what the engine should ultimately be like), it is much easier and more efficient to modify the cylinder head (cylinder head) and then install a suitable camshaft. This type of boost will also make it possible to increase the power performance of the power unit.

Of course, to maximize all the capabilities and reserves of the camshaft, a fairly serious modification of the cylinder head will be required, which may even include repressing the seats and installing valves with a large diameter. For example, engines characterized by the presence of eight valves will be suitable for similar parts from BMW, and sixteen-valve engines will be suitable for components from Opel and Volkswagen. At the same time, one should not lose sight of the intake/exhaust channels intended for circulating the fuel-air mixture - they also require improvement. Their improvement involves increasing the cross-sectional diameter to maximum dimensions through internal polishing.

The technical characteristics of the VAZ 2109 cylinder block, like other components, leave their mark on the overall performance of the engine. You can, of course, study in more detail the influence of the types and shapes of pistons, the weight of crankshafts and much more that is somehow reflected in the operation of the engine, but this article is not about that.

The following characteristics have a particular impact on the performance of the internal combustion engine: the ratio of the length of the connecting rod to the piston stroke and the dimensions of the crankshaft crank (diameter).

Dimensions of parts and their weight

The importance of the above parameters is due to the fact that the engine is essentially a pump that pumps a certain amount of mixture through itself over a specific period of time. It is these characteristics that will be discussed further.

What will happen to us for this?

Sports cars are famous for their noise effects, and driving down your street sometimes leaves the impression of the start of a nuclear war. It’s quite simple to explain - the exhaust system is just configured a little differently than other cars in this series, which leads to noise that is unpleasant for city residents and pleasant for the driver. Feel the power hidden under the hood of your almost-Mustang. Having lost in noise, you will get another more pleasant nuance - an increase in engine power within 3-5 horses, which will make any car enthusiast rejoice with joy.

Here you need to give a clear example with the installation of any product, the cost of these parts is relatively inexpensive ($250-300), but the result will not take long to arrive. After installing such a thing, your previously choking old VAZ 2109 will get a second wind and start thundering in a completely different way.

If you follow strictly the instructions given above, pay attention to the jets and understand a little about ignition issues, you can increase the engine power from 5 to 10 horsepower, without any damage to engine life.

We resort to serious processing - boring the cylinder block

You can also increase the engine power by boring the cylinder block. Due to this, the volume of the combustion chamber increases, which means that a larger amount of the fuel mixture is placed in it. When choosing this method of modifying an installed motor, the following points should be taken into account:

Increasing the volume of cylinder blocks does not lead to a significant increase in fuel consumption. This work can only be carried out if you have certain experience and equipment. When changing the design, one should take into account the fact that the walls of the cylinder block become thinner. At the same time, the design has channels for the cooling system

Therefore, attention should be paid to the calculations carried out

Boring a cylinder block yourself is possible only if you have the required equipment and certain skills. The surface must be strictly cylindrical and free from significant defects. Otherwise, the engine will begin to wear out quickly.

In a nutshell about the features of the Solex 21083 carburetor

Solex is an emulsion type; it was used for models with a non-contact ignition system for the combustible mixture. The Solex carburetor has two chambers with sequential opening of the throttle valves. In addition, the carburetor is equipped with two chamber metering systems, an idle speed system for the 1st chamber with transition systems for the first and second chambers. Solex contains a semi-automatic starting device, a diaphragm accelerator pump, and a power mode economizer.

Carrying out mechanical processing to change the design of the cylinder block

The performance characteristics of the engine can be significantly changed by machining the internal surfaces of the internal combustion engine cylinder head. Certain changes can significantly change the characteristics of the engine. The main goal that many people want to achieve is to significantly increase the degree of filling of the cylinder. The greater the fuel-air mixture, the more power the installed unit has.

The engine that is installed on a car at the factory does not have a perfect design. Almost all structural elements are far from ideal shape

In mass production, attention is often not paid to the quality of the channels. Based on the peculiarities of the law of flow of liquid and gases through channels, it can be said that the tube must have an absolutely flat and straight surface

When the valve is open, the mixture enters the combustion chamber, which determines the swirl of the flow. After this, the flow breaks down and enters an area with a large volume; the valve resists the movement of the air-gas mixture. Tuning the VAZ 2108 engine allows you to significantly reduce resistance, which means efficiency increases significantly and engine power increases.

Insert: Important: When producing a cylinder block, it is taken into account that the internal surface must be without various differences. The valve should have a flat shape with rounded edges, like a seat

The treatment is also carried out so that the mixture returning to the cylinder does not stop abruptly, that is, the power does not drop; the shape at the point where the mixture exits the channel is processed. Such a change allows not only to significantly increase the volume of each cylinder, but also to increase the maximum time during which the valve remains open. Increasing the start phase allows you to increase the power of the installed motor by 30, 50 or even 100%. However, it is worth remembering that the design of the original motor is not designed for such high power, which means the service life is significantly reduced.

Table

A few important points

I would like to note that any modifications to the VAZ-2110 car must be carried out in a place prepared for this. If you are going to upgrade the carburetor, it is advisable that the room is well ventilated, because you will be dealing with gasoline vapors. It is also better not to smoke while performing work; sometimes you even need to wear special glasses. It is also worth paying attention to the fact that it is advisable to have clean water and dry rags with you. All of this will help you in one way or another. When it comes to working with the engine, remember that if you are not sure about something, it is better to read about it again or find out from a mechanic you know, because you can only make things worse, and engine repair is not cheap. It is worth noting once again that if you are modifying the stove, then it is best to buy corrugations at a car dealership, as they will be more suitable for your purposes.

Also, many car owners want to make the car a little quieter, so they install their own sound insulation for this. Here, too, it is advisable to go to a specialized store and not save money, then the result will please you. Remember that the VAZ-2110 car, which you will modify with your own hands, although it is the brainchild of AvtoVAZ, it is a pretty good and demanding car. Therefore, before adjusting the steering rack, add oil, perhaps the situation will improve. Before sinning on a faulty carburetor, change the fuel and air filters.

Two options for tuning the VAZ 2109 engine

The first, and the simplest and most inexpensive option for tuning a VAZ 2109 carburetor engine is the usual alteration of the engine components, which any master can grind, polish, and bore. This alone may be enough to slightly improve the performance properties of the car. But, if you want to get closer to the ideal, then you should turn to the second option - serious processing of the “heart” of the machine.

tuning engine vaz 2109

When tuning the VAZ 2109 engine, pay close attention to the camshaft, phase adjustment and lift height. Replacing these particular parts allows you to increase the power of your car.

VAZ 2109 engine tuning

You can use any of the methods that include installing a lightweight crankshaft with a piston stroke of 78 millimeters, lightweight connecting rods measuring 121 millimeters, lightweight piston rings, forged pistons with a diameter of 82.5 millimeters, a cylinder head taken from a LADA Kalina car and a camshaft measuring 11.3 millimeters. All together, this will allow you to get engine power of 98 horsepower and the ability to reach speeds of up to 183 kilometers per hour.

As an option, you can use titanium springs on the piston with connecting rod. This will allow for a rational distribution of energy during fuel combustion. On the one hand, this allows you to save fuel, and on the other hand, it increases the power of the car.

In short, when tuning a VAZ 2109 engine is carried out, its carburetor can also be replaced. But in general, when tuning a carburetor engine, remember that to improve the quality of its operation, it will help to weaken the friction force in the “cylinder-piston-ring” chain, reduce the weight of connecting rods, pistons and pins, reduce the thickness of the piston rings, and reduce their number.

tuning carburetor engine VAZ 2109

Tuning the VAZ 2109 engine: injector. Note that an electrified car does not require any mechanical intervention. To change the technical characteristics of the mechanism, you only need to change the settings of the electronic control unit of the entire engine.

Sports tuning of the VAZ 2109 engine

If you are dreaming and see yourself as a winner at sporting competitions, then you should start boosting the engine of your car for sporting purposes. To do this you will need a lightweight crankshaft, lightweight connecting rods, lightweight pistons, a new gearbox, oil injectors, a new clutch and a lightweight flywheel. Plus, you will need to install a contactless ignition system, a sports muffler and a copper radiator.

Life after tuning the VAZ 2109 engine

I would like to remind you that if the parts of the “nine” differ at least in some way from the standard factory elements, then even a minor breakdown on the highway will lead to the fact that you will need to call a tow truck or use a cable, again, causing help from someone you know.

Yes, it will become more difficult to repair a modified car engine, which is why the cost of repairs may be prohibitive. To reduce it, all you have to do is carry out the repairs yourself. Yes, tuning a VAZ 2109 is a serious matter, and there are pitfalls.

VAZ 2109 engine tuning carburetor

Another point worth paying attention to is fuel consumption. For example, if you install a camshaft with an increased phase, the engine will respond to this with greater fuel consumption

Naturally, this can be compensated for by replacing other elements, gradually bringing the car closer to what you consider ideal.

Finally, we recommend watching a video of VAZ 2109 internal combustion engine tuning, maybe it will be useful in the modernization process.

What else will need to be improved?

The car is an engineering marvel. This is a complex technical system in which all elements interact with each other and depend on each other. And the engine is the central link of this system. Any brand was designed in such a way that everything in it was tailored to the operation of the installed unit. If you change the characteristics of the engine for the better, be prepared for the fact that you will need to make improvements to other mechanisms to achieve the lost balance. Let's list the most important points:

• The brake system of the VAZ 2106 is not designed for strong engines. We'll have to install more efficient brakes.
• The transmission must also be modified to support the new engine performance.
• The exhaust system will need to be reworked.
• If a carburetor is installed on the six, you will need to replace it with an injector.
• The suspension will also not be able to cope with a stronger engine, so the springs and shock absorbers will have to be changed.
• To increase body rigidity, you will need to install additional spacers.

If all this work is not done, then the car will simply not be able to cope with the new sharp engine, handling will become dangerous, and the chassis may simply fall apart.

Crankshaft. Since the pistons and connecting rods have become lighter, the balance in the system is upset. This means that it is necessary to restore the balance with the clutch basket, with the pulleys and with the flywheel. The best solution to this problem is to install a fully counterbalanced crankshaft. It has a heavier weight, its strength is much higher. If you do not replace the crankshaft, then tuning the engine will not bring the desired result - after all, all elements of the system must work in harmony with each other.

Camshaft Modifications to the engine inevitably lead to replacement of the camshaft. Moreover, you can select one of two types depending on your driving style.

If a car enthusiast prefers to drive at high speeds, then the car needs to install a top shaft. It allows you to increase the revs in the red zone, allowing the engine to get the best torque in this zone. This effect is possible due to the fact that wider and more powerful cams are used. They push the valves more efficiently, their opening process takes longer and they open more. However, problems arise when idling. You have to update the ignition system controller program. And the ignition system itself should be replaced with a more modern one.

If the car owner prefers to drive at medium and low speeds, then a lower shaft is best suited. At low speeds, it provides increased torque, which improves the vehicle's maneuverability on difficult road sections. This also reduces fuel consumption.

Chassis. It is impossible to modify the engine and get a good result without making changes to the chassis. The chassis must be brought into line with the new engine characteristics.

First of all, improvements affect the braking system. Ventilated discs should be installed on the front wheels. And disc brakes are installed on the rear wheels instead of drums. The caliper must now be installed from the VAZ 2108. You must remember that you will have to adjust the axle shaft to the new mounting diameter of the brake disc. The caliper is installed in the same way as it is installed on the front brakes. The axle bearing is also being replaced by SKF. It is also necessary to replace the main brake cylinder with a more reliable, foreign-made one.

You cannot do without installing shock absorbers of increased rigidity and reinforced springs.

To increase body rigidity, you will have to install new spacers. One of them is installed under the hood, which increases the rigidity of the space between the side members and the attachment points of the front struts. The second spacer is mounted in the luggage compartment, which allows you to fix the location of the mounting points for shock absorbers and springs.

Steering system. A faster engine combined with a standard steering wheel is not the best idea: the car becomes almost uncontrollable on the road. You'll have to make the steering wheel stiffer. To do this, you will need to work on strengthening the anti-roll bar. To do this, the standard stabilizer is shortened and individual mounts are made. This procedure is long and unpleasant, but it allows you to improve the car’s behavior on the track.

So, if you want to get more dynamic acceleration, reduce fuel consumption, improve maneuverability on difficult sections of the road and make the behavior of the VAZ 2106 more manageable, then engine tuning will help you with this. However, remember that to achieve balance you will have to make modifications to many other elements of the system.

How to increase the power of a VAZ 2109 engine (carburetor) with your own hands

The vast majority of Nines are powered by carburetor engines. Many actively praise the injectors, but, nevertheless, this did not affect the total number of carburetor versions.

The VAZ 2109 car has a DAAZ 2108-1107010 carburetor. Dimitrovgrad residents do not grab stars from the sky, and the carburetors coming out of their assembly line are frankly different. One can serve five to ten years without complaints, while another, for no apparent reason, can suddenly refuse to work. True, the problem is not always a manufacturing defect.

Often such difficulties arise from dirt or bad gasoline. Or from a not very smart driver. There may be incorrect “non-original” jets, which also leads to problems.

Device

VAZ 2109 tuning Solex carburetor

Before tuning, you need to know how the Solex carburetor works. It was produced in several modifications and on the VAZ 2109 it was installed either DAAZ-2108 or DAAZ-2183. The first of the carburetor modifications was installed on a 1.3 liter engine, the second on a 1.5 liter engine. These carburetors are devices that are designed to accurately meter fuel into the air stream. The Solex carburetor also has the following features:

• It is in the carburetor that the process of forming a combustible mixture from fuel and air takes place, with its subsequent supply to the engine cylinders (see When replacing a VAZ cylinder is not necessary);
• Note that the Solex carburetor has two vertical channels called chambers.

Solex carburetor design

Note. A throttle valve is provided at the bottom of each chamber to allow air to pass through.

• Due to the fact that there are two chambers, and the damper drive is designed in such a way that as you press the gas pedal, one and then another channel opens, such a carburetor is called a two-chamber carburetor.

Note. The chamber that opens earlier is called primary, and the one that opens later is called secondary.

• Among the main features of the carburetor, we also note cone-shaped narrowings, called diffusers. They are needed to create the vacuum necessary to suck fuel from the float chamber (a special container in the carburetor body).

Note. The fuel level in the float chamber is constantly maintained to ensure normal carburetor operation.

• The Solex carburetor consists of two main parts: upper and lower. The flange housing, air filter fixing studs and fuel fittings are what the upper part consists of. The lower part consists of the housing, diffusers, float chamber and throttle valves.

Technical parameters of DAAZ-2108/2183 carburetors

Characteristics of the motor 2111

Since 1993, the manufacturer AvtoVAZ opened the VAZ-2110 project. A front-wheel drive luxury sedan was being developed, so carburetor modifications of engines 2108, 2110 and their variants did not meet the conditions.

Already at the initial stage, the project was divided into two independent works. A simple conversion of the G8 hatchback into a sedan was called VAZ-21099. The name of the second project remained the same, but work on it was considerably delayed for a number of reasons:

• in 1985, a test sample appeared; the car with the new engine was planned to be launched into series in 1992;
• the crisis confused plans, the management of the manufacturer's plant put the VAZ-2110 on the assembly line only in 1996;
• The first cars had a carburetor internal combustion engine, then a modified 2111 injection type.

Motor diagram

The designers managed to make maximum use of existing engine elements so that the user of previous generations of VAZ would not be confused about which oil and coolant to use. By default, the technical characteristics of the ICE 2111 are as follows:

Refinement of the cylinder head

Oddly enough, increasing the displacement is not always a profitable method of boosting the engine. Sometimes motorists resort to modifying the cylinder head and replacing the camshaft with a tuning one (that is, non-standard). In fact, this method is truly impressive in its effectiveness. However, this requires a lot of time and effort, since the modification will concern not only the block head. This may include pressing in other seats or installing new valves with a larger diameter. If you make such an engine repair, the VAZ-2109 will be 5-15 percent more powerful, depending on the amount of work done.

First aid for a car

The first step in such cases is to check the battery terminals; perhaps they are not making good contact. If there is poor contact at the battery terminals while driving , it will not be charged sufficiently, which may cause problems during further operation of the car. To fix this problem, you need to lubricate the terminals and tighten them.

If your car's alternator fails, you need to have it repaired immediately. the voltage regulator fails . The failure of this generator element has rather unpredictable consequences. While driving, the regulator controls the required amount of current for the car; if it fails, the voltage in the network changes and can be either more or less. Very often, fuses blow at high voltages.

How to increase the engine power of a VAZ 2109 carburetor?

Some VAZ owners believe that an imported carburetor can significantly affect the increase in power of the VAZ 2109 engine. But comparative tests of the domestic DAAZ and the Italian Weber showed that there is no huge gap at all. In addition, the Weber consumes more fuel and has higher CO emissions at higher speeds.

The maximum speed is also higher with “our” Solex carburetor. If up to 80 km/h there is almost no difference, then above a hundred Weber immediately begins to lose ground. And his single-cameraness is to blame.

To change the power, the VAZ 2109 carburetor is tuned.

Let's consider the options (in this case for Solex):

• You can start modifying the accelerator pump.
• Replace the standard carburetor with another one that has more calibration data. Suitable, for example, from Niva.
• Take jets and tubes with a larger diameter cross section. But the main thing here is not to overdo it. Otherwise, the correct formation of the mixture will be disrupted and the engine will not start at all.

Improve the mixture formation process by refining diffusers, chambers and throttle valves. In general, tuning a VAZ 2109 carburetor with your own hands is a very real task.

Which is better, carburetor or injector? | Topic started by Rayne

The difference Dmitry is in the power system, I drive an engineer and don’t worry, if it was worse than a carb, they wouldn’t be produced, is it logical? Dmitry (Kozue) Well, that’s it...

Alexey (Dwain) They seem to say that the engineer is more cheerful.

HZ didn’t drive it myself, I don’t have any complaints about the carb)

Misha (Lance) Carb is the best and cheaper to make

Alexey (Dwain) MISHA +1!

Igor (Falak) And he eats more on the carb and in winter he constantly jerks off, then add suction or turn it down, the carburetor is a thing of the past, and those who say that the carburetor is better simply haven’t driven an engineer, and are jealous of those who have an engineer! IMHO

Alexander (Stiles) The injector is easier in winter. The engine is almost inaudible. And it rips great. I recommend the injector. (I myself had both a carb and an injector)

Andrey (Yizream) But when finalizing the movement, you need to change your brains

Nikita (Tamasa) polyubas injector

Vadim (Jaquelin) With an injector you will stand on the road and that’s it, but you can tinker with the carburetor….

Igor (Falak) What are you picking up?

Denis (Anjela) The injector is fast and convenient, there are no options, the carbure itself plus filter 0 is no worse than an engineer pounding :), well, I want a mono-injection.

Igor (Falak) is like setting up both engine and carb, but in any case the carb eats more

Alexey (Dwain) inzhekor is faster and more economical.

Misha (Lance) #7 Igor Vladislavovich March 22, 2009 at 1:46 And he eats more on the carb and in the winter he constantly jerks off, then add suction or turn it down, the carburetor is a thing of the past, and those who say that the carburetor is better simply haven’t driven an engineer, and They envy those who have engineering! IMHO

Is it difficult for you to put your hand under the steering wheel and take the choke in your hand? ))))

Igor (Falak) I go out in the morning, start it in the winter, and go home to drink tea, after 20 minutes I come and get into a warm car and don’t have to freeze, or even start it from the key fob when it’s not too cold. Agree Mishanya, it’s more convenient

Andrey (Yizream) I don’t need to rebuild the carburetor, I have a 9ka at least 15 eats already fucked up

Misha (Lance) I don’t know who set it up for you like this, but I have 8 liters and it’s rushing, but about the fact that there the injector can be started from the remote control and the carb can also be made

Igor (Falak) Misha, if you had a choice of taking the carb or taking the engineer?

Misha (Lance) I like the carb better

How to increase engine power VAZ 2109 carburetor video

Specifications

Before we begin to describe the process of refining and increasing the power of the VAZ 2109 carburetor engine, it is worth understanding what power units were installed on the vehicle, and also consider the main technical characteristics.

During the production process, the “nine” was equipped with three options for carburetor engines:

21081 (1.1 8V)

2108 (1.3 8V)

21083 (1.5 8V)

First engine

Initially, the “nine” was equipped with one 1.3-liter gasoline engine, which produced up to 64 horsepower. This unit is eight-valve, with a carburetor type of power supply. Injection prototypes appeared only in the early 2000s.

With such an engine, the car reached “hundred” in 16 seconds. At the same time, its maximum speed according to the passport data was 148 kilometers per hour.

Tuning the VAZ 2109 engine - a powerful nine!

If we are talking about high-quality and major tuning of a standard unit from the “nine”, then there are several effective modernization options. The simplest and most affordable way is engine chip tuning, which will significantly improve the dynamic performance of the engine and will not require large financial investments. However, in addition to chip tuning, there are many more ways to modify an injection and carburetor engine to obtain more output power.

Complete tuning of a VAZ 2109 engine with an injector cannot be done without completely disassembling the engine and other elements of the system.

A way to find out why the CHECK light is on!

Using a universal auto scanner, you can do the diagnostics yourself in 2 minutes and find out why CHECK is on. Suitable for all cars..." Read more >>

High-quality engine modernization involves replacing the piston group, installing a new cylinder head, installing an intercooler or turbine, etc., etc.

Thus, when modifying the cylinder head, the shape and diameter of the intake valves and combustion chamber changes. In this case, one cannot do without installing a new sports receiver and a different camshaft, which can significantly increase the power of the VAZ 2109 engine.

Tuning the VAZ 2109 carburetor means upgrading other elements of the system. The most common option is to install an additional carburetor and manifold, for example, from Oka. The main advantages of a carburetor engine are the ability to run on low-octane gasoline and greater maintainability. Some owners prefer to convert the VAZ 2109 carburetor engine to an injector. This procedure is very costly financially and is not always justified from an economic point of view. It is possible to replace the carburetor with an injector on the VAZ 2109 model with your own hands; this will require special equipment, knowledge, time and patience.

The first step to increase the power and dynamics of the motor is to install a zero-resistance filter. A properly installed good filter can add up to 5 percent of engine power, but when installing a zero filter, you must understand that it must be constantly cleaned and monitored, otherwise there is a risk of engine damage over time. A high-quality zero-resistance filter costs about 70-100 dollars - everything that is offered on the market cheaper is just a waste of time and money.

Installing a direct-flow muffler on a VAZ 2109 injector is justified only if the engine has undergone major technical modernization or an additional turbine has been installed. In other cases, a direct-flow muffler (and its installation is not cheap) will only add noise and roar to the car, but this will not affect the power in any way, as can be seen in the video presented.

Another effective way to increase the power of the VAZ 2109 is to install a sports series for the gearbox. This procedure allows the car to demonstrate improved acceleration dynamics by changing a number of gear ratios and adding an additional 6th gear. This does not affect the overall power level, but changes in dynamics will be noticeable immediately. It is recommended to do such tuning of the gearbox after replacing the engine piston group and installing more powerful parts and mechanisms.

IT IS IMPORTANT TO KNOW!

Every motorist should have such a universal device for diagnosing his car. Nowadays you can’t live without a car scanner!

You can read, reset, analyze all sensors and configure the car’s on-board computer yourself using a special scanner...

However, the simplest and most effective way to improve engine performance is chip tuning. If the VAZ 2109 is equipped with an injection engine, then with the help of chip tuning you can achieve excellent results as shown in the video. You can calibrate ECU parameters yourself, using modern programmers and having a computer and some equipment. With chip tuning there is no need to carry out mechanical work, everything is done using a computer and programs, and improvements become noticeable from the first day of operation of a car with a reflashed ECU.

Tuning process

Do-it-yourself VAZ 2109 engine tuning begins with removing the engine from the car. So, you will have to turn off the power supply, ignition system and other systems. So, let's look at all the stages of modifying the engine yourself. It is impossible to carry out complete tuning with your own hands, since you will still have to contact a car service at some stages.

Removing the motor

To remove the engine you will have to go through a certain process of disconnecting and dismantling the auxiliary systems. So, let's get started with the process:

1. Remove the battery and holding shelf.
2. We remove the air filter and carburetor.
3. We remove the ignition elements that are located in the engine compartment.
4. Drain the coolant and engine oil.
5. We unscrew the gearbox from the internal combustion engine.
6. We dismantle the radiator to make it easier to remove the engine.
7. We take out the engine CV joint.
8. Unscrew the engine mounts.
9. We remove the hood and dismantle the engine.

The described process is not complete, but only the basic actions that need to be done.

Disassembling the power unit

Disassembling the power unit is done in a few hours. So, first you need to dismantle the cylinder head cover and the oil pan. It is best to carry out this operation on a special stand.

After this, we begin to remove the main components. Unscrew the bolts securing the cylinder head and cylinder block. Then, we set the head aside and work directly with the cylinder block. So, let's look at what you have to remove:

1. Unscrew the yoke and remove the crankshaft. First we dismantle the pulley.
2. We dismantle the water and oil pump.
3. We take out the piston group. We dismantle the connecting rods. If there is, you need to remove the sleeves.
4. Now, the block is ready for further manipulations.
5. The last step is washing the parts and the block.

Once the block is disassembled, you can proceed to disassembling the cylinder head.

1. Remove the camshaft cover.
2. We remove the camshaft.
3. We dry out the valves.
4. Remove the springs and seals.
5. We take out the valves.
6. We knock out the saddle and guide bushings from the head.
7. We wash the parts and the base of the head.

Determining Rework Priorities

To increase the power of the VAZ 2109 carburetor engine, you will need to purchase a piston group, valves, camshaft, connecting rods and crankshaft. All these parts must be lightweight and manufactured by tuning manufacturers.

Thus, the piston group, valves and seats are suitable for ATI. It is best to install bronze guide bushings made by the American manufacturer K-line. The crankshaft and camshaft are purchased from the German company TDR.

Working with the cylinder block

To begin with, the cylinder block must be bored for new pistons, respectively, with a size of 82 mm. Then, the crankshaft and new bearings, which come with the main part, are installed.

To make everything work like a clock, you need to install a lightweight tuning clutch manufactured by Sachs. After the clutch is attached to the shaft, balancing must be done. It is advisable to carry out the operation on a special stand.

We assemble the piston assembly, namely, we attach the pistons to the connecting rods. Then, you can begin the so-called “dressing” process. This refers to the attachment of connecting rods with pistons to the crankshaft. We install the crankshaft oil seals and bearings. We install the yoke and you can fix the pallet. Then, the remaining auxiliary components, such as the pulley, water pump and roller, are assembled.

Head tuning

Tuning a cylinder head is actually assembling new parts onto old seats. So, a disassembled cylinder head is assembled from an old body and new tuning elements. There is nothing complicated in this process.

Assembly of the unit

After the main systems and components have been assembled, you can proceed directly to the process of assembling the engine together. So, in reverse order, the cylinder head, valve cover, pulleys, and timing belt are attached to the cylinder block.

After assembly, it is recommended to run the engine cold, but since not everyone has a running stand, most motorists carry out this operation hot, directly on the car.

Refinement of auxiliary systems

After the main components of the power unit have been assembled, you can begin installing auxiliary systems. So, first of all, we install the fuel injection system. An old Solex carburetor should not be installed, since it will not supply the required amount of fuel to the combustion chambers. Therefore, it is necessary to find an improved Solex Mega-2 carburetor or the Czech version - IKOV.

It is worth modifying the ignition system. Instead of standard spark plugs, it is worth installing Brisk spark plugs marked A2. Also, standard high-voltage wires are replaced with a tuning version produced by Tesla.

Do not forget about the cooling system, since an increased number of crankshaft revolutions will speed up all processes, and accordingly increased heat emissions. Therefore, a kit cooling system is installed on the VAZ 2109, which includes: silicone pipes, a sports pump and a two-chamber thermostat. It is also recommended to install a sports radiator made of aluminum. This will lighten the weight of the car by several kilograms.

The final modification is the installation of a “zero” resistance air filter. Installation of this unit is quite simple; it is “aired” onto the standard fastenings of the old case. The air intake is oriented so that there is a direct air supply.

Also, in addition to standard modifications, an air supercharger can be installed on the engine. Of course, such a modification wears out the engine elements faster, so it is recommended to install a “snail”.

After all modifications have been made, the engine is installed on the vehicle, and running-in and adjustments are carried out.

We resort to serious processing - boring the cylinder block

You can also increase the engine power by boring the cylinder block. Due to this, the volume of the combustion chamber increases, which means that a larger amount of the fuel mixture is placed in it. When choosing this method of modifying an installed motor, the following points should be taken into account:

Increasing the volume of cylinder blocks does not lead to a significant increase in fuel consumption. This work can only be carried out if you have certain experience and equipment. When changing the design, one should take into account the fact that the walls of the cylinder block become thinner. At the same time, the design has channels for the cooling system

Therefore, attention should be paid to the calculations performed.

Boring a cylinder block yourself is possible only if you have the required equipment and certain skills. The surface must be strictly cylindrical and free from significant defects. Otherwise, the engine will begin to wear out quickly.

The risk is worth it

Extreme automotive enthusiasts, risking literally everything, arrange a complete modernization of the internal combustion engine. To say it's risky is an understatement. All that remains of the old spare parts in the new engine is the block. In this case, almost everything changes, from an increase in the volume of the working stroke to the injection rate of the air-fuel mixture. This entire system is covered on top with a 16-valve head from a VAZ, which further leads to an increase in horsepower to 120-130. Do not try to repeat such operations without prior training from more experienced comrades; this modernization method is only available to highly qualified tuning centers. The camshaft and intake system, in principle, can be replaced by any car mechanic; no special knowledge or effort is required, but in our case these minor skills are clearly not enough.

It is worth remembering that such a surgical intervention can destroy the transmission of a new car. First of all, the gearbox will come under attack, then the clutch will die for a long time, and then the drives will burn out. I think the consequences are obvious. Therefore, “cheap” intervention in the life of the internal combustion engine will lead to expensive modernization, or even replacement of the entire transmission.

Some eccentrics even manage to reduce the steps in the gear ratios between first and second gears. But the end justifies the means, and this method also has a right to exist.

Poor quality fuel

The first thing you need to check is how high-quality the fuel was poured into the vehicle. If the gasoline was of poor quality, then most likely one of the elements of the fuel system was forgotten. So, the motorist will have to find out what the fuel supply scheme is and find parts that could have failed.

So, the first element that comes under scrutiny is the spray nozzles. Malfunctions of the injectors can cause unstable operation of the engine, which will lead to tripping. A special stand is used to diagnose and clean the unit, but many motorists carry out the process themselves, using carburetor cleaning fluid.

Also, unstable engine operation may be caused by clogged fuel filters. One is located under the rear right wheel, and the second is in the fuel pump. There is a filter mesh on the fuel pump intake that needs to be replaced. The process is quite complicated, since you have to remove the rear seats and remove the fuel supply element. But the fuel filter under the wheel can be changed quickly and without any problems.
