How to increase the power of a VAZ-2114 8 valve engine

On cars of the Samara 2 series, the Volzhsky Automobile Plant installed injection engines with electronic, distributed fuel injection. And for the VAZ 2114, which appeared in 2001, and was launched into series in 2003, such a power plant was developed - model 2111. In subsequent years, various modifications of this car were produced and some of them were equipped with other engine models, such as - 21114, 11183, 21124 and 21126. But the most popular production cars were the VAZ 2114 with engines of models 2111 and 11183.

How does the VAZ-2114 engine work?

The main feature of this type of engine is the presence of an injection system. The engine is four-cylinder, with two valves (intake and exhaust) on each of the cast iron cylinders.

Several types of engines were installed on the VAZ 2114. The 8-valve engines that can be found on this car model include:

1. VAZ-2111 - its volume is 1.5 liters, maximum power is 78 hp, maximum torque is 116 Nm.
2. VAZ-21114 – 1.6 l, power 80-84 hp, maximum torque – 125 Nm.
3. VAZ-11183 - 1.6 l, maximum power 81-82 hp, maximum torque - 132 Nm. This type of engine is also available with 16 valves, but we are considering an 8-valve one.

The service life of the VAZ-2114 engine, according to the manufacturer, is 150 thousand km. With careful handling and modification of the engine in a safe way, this resource can be extended.

In order to improve the power and other performance indicators of the engine, it is necessary to modify it - tune it.

Typical breakdowns

The very first 1.5 liter engine 2114 has disadvantages:

• periodic valve adjustment;
• unreliable injection system;
• loosening the exhaust manifold nuts;
• Leaking gaskets of the fuel pump, distribution sensor of the ignition system.

The next 1.6 liter engine does not cause any particular problems for the owner, with the exception of high vibration and noise loads. The weak point traditionally remains the valves, which have to be constantly adjusted.

The internal combustion engine from Lada Kalina 11183 was installed on the fourteenth model solely to meet Euro-3 standards. It has typical disadvantages for a linear series and is no different.

The first sixteen-valve engine 21124 does not bend the valves, the gaps in which are adjusted by hydraulic pushers. However, the belt needs to be tightened after 15,000 km due to the large number of attachments. The second and last in the line of fourteenth ICE models, ICE 21126, has increased power. In addition to typical malfunctions, if the timing belt breaks, the piston will bend the valve due to insufficient recess depth.

How to increase engine power

There are various ways to modify a VAZ 2114 8 valve engine at home. They can be used either separately or in combination, depending on the desired result.

Increasing the volume of engine chambers

There is a direct proportional relationship between engine size and power. The most popular option for the VAZ-2114 is to increase the volume from 1.5 to 1.6 liters. (or from 1.6 liters to 1.8 liters depending on the specific engine model). To increase volume, you need:

• install a lightweight crankshaft;
• replace the pistons with forged ones and replace the piston rings with lightweight ones;
• change the connecting rods that connect the pistons to the crankshaft;
• increase the diameter of the cylinders and grind the surface (this is done to increase the number of crankshaft revolutions).

As a result, the engine power increases by about one and a half times. But this also increases fuel consumption.

It is also necessary to replace the oil nozzles - forged pistons require oil cooling. And in the process of boring parts, old injectors become unusable.

Installing a new air filter

To increase engine power, an intake filter with reduced aerodynamic drag is used. As a result, air enters the mixer with less effort. This can add an additional 5-8 horsepower to the engine. At the same time, fuel consumption is reduced.

To tune the intake system, you need:

• polish the internal intake channels (done in car repair shops);
• install receivers;
• install a throttle valve with a larger diameter.

The exhaust system is also modernized by installing a direct-flow muffler.

Important! Boring and grinding of intake channels should not be done at home. This work requires increased precision, so it is better to contact a specialist for this.

Turbocharging installation

This is one of the most effective, but at the same time costly, methods for tuning the 2114 engine. The increase in engine power depends on the type of turbine used:

• low pressure turbocharger – increases engine power by 15%. This is the least labor-intensive option for installing a turbine;
• high-pressure turbines - increase engine power by 25-30%.

If a turbine is installed on a VAZ-2114, there is a high probability of premature exhaustion of the engine's life. This is due to the fact that all working elements wear out ahead of schedule.

Tuning the gas distribution mechanism

This method does not lead to early exhaustion of the engine's life and allows to reduce fuel consumption. To increase engine power, it is necessary to reduce the timing resistance and optimize its phases. Necessary:

• bore the valve seats;
• replace the intake and exhaust valves with lightweight ones;
• you can change the guide bushings to lighter ones;
• install the split gear and adjust it properly.

The most important element in timing belt tuning is the split gear. It is this that optimizes the valve timing.

The adjustment should be made at the moment when the piston is at its highest dead center - TDC. It is first necessary to adjust the position of the camshaft.

For lower and middle speeds, you need to reduce the angle of gas-dynamic boost and increase the opening angle of the exhaust valve. To adjust the gear, you need to turn the camshaft as the crankshaft rotates.

For high speeds, the camshaft should be turned in the opposite direction relative to the crankshaft stroke. Thus, the angle of gas-dynamic pressurization increases.

Tuning options to improve ride

Do-it-yourself tuning of a VAZ-2114 involves replacing several factory parts with analogues with improved characteristics or modifying already installed ones. Here are the most common options:

1. Bore the cylinders to increase their volume.
2. Replace the air filter.
3. Install the supercharger.
4. Introduce control of the electronic parameters of the machine into the system.

Each change will still affect the service life of the machine, so it is worth considering the work carefully before starting.

For example, boring the pistons will increase engine power by 7-10%. For full effect, it is necessary to replace the crankshaft and intake manifold. With the new parts, power will increase by 45-50% for a total cost of $440. But with such modernization the amount of fuel consumed will also increase.

Replacing a conventional air filter will provide a slight increase in horsepower. Instead of the factory one, you will need to install an aerodynamic filter. Air will better enter the combustion chamber, which will increase the rate of formation of the combustible mixture.

An increase of 5-7% depends on the part. Installing a supercharger can give an increase in speed characteristics by 10-15%, but at the same time the load on the parts of other components, including the transmission when changing gears, will greatly increase.

Content

The car engine is the main power unit, on the characteristics of which much depends. Every year, the design of internal combustion engines becomes more complex and more efficient. However, this point does not apply to domestically produced cars - the installed engines are improved only in appearance, in general the design remains unchanged for many years. In order to significantly improve the driving performance of the car, the power unit should be modernized.

Sidebar: Important: With the right approach, you can significantly increase power or reduce fuel consumption, make engine operation more reliable, and make the sound more attractive.

Let's look at all the features of how to tune a VAZ 2114 engine: methods, possible improvements, problems with modernization and much more.

VAZ engine chip tuning

A change in the design of an internal combustion engine can be called a significant modernization, which will lead to a change in its basic characteristics. However, this tuning method is quite expensive; it can only be done independently if you have certain skills and experience, and the end result is impossible to predict. Some VAZ vehicles are equipped with on-board computers that regulate the operation of the internal combustion engine. The installed program determines the main characteristics of the engine: it affects power, speed limit, fuel consumption, idling and other features of engine operation.

When considering chip tuning, we note the following possible results:

• Increase power by 5-10%. At the same time, the possibility of increasing power depends on what settings were set at the factory, that is, whether a power reserve was left, as well as on the condition of the engine. There are cases when engine power was increased by 20%, which can significantly reduce the service life of the unit.
• Fuel consumption can be reduced by approximately 5%. Reducing fuel consumption will lead to a smooth increase in speed, that is, a quick start from a traffic light will no longer be possible. Therefore, this modification is suitable for the driver who is more concerned about savings than the driving sensations.
• Make idle smoother and more stable.

Tuning the VAZ 2114 engine by installing new firmware should be carried out exclusively by professionals, since mistakes made can lead to significant engine failures. Recently, there is no need to remove the on-board computer to read information from it and rewrite the program - the connection is made through a connector, for this a computer and a special adapter are used. During operation, only partial disassembly of the panel in which the connection connector was hidden is performed.

The work on flashing the chip looks like this:

1. Engine diagnostics are carried out to identify faults. 2. After determining the state of the internal combustion engine, a computer is connected to the chip. 3. When you connect a computer, tables with the configured settings are loaded. 4. The programmer loads preset settings, for example, to increase power by 10%. 5. After making the settings, the engine is tested and adjustments are made.

It should be understood that unique settings are selected for each engine, which depend on the state of the internal combustion engine and other factors. It is possible to carry out the work in question independently, but only if you have certain knowledge and experience. Mistakes made can lead to settings being reset and invalid parameters being set. It should also be taken into account that after chip tuning, it is necessary to perform engine diagnostics, since otherwise there is a possibility of severe wear due to the introduction of incorrect parameters.

Optimal tuning kit

Chip tuning of the VAZ-2114 allows you to change the factory settings of the electronics. In this way, you can change the ignition timing, the operation of the injection system and other little things. The increase in “horses” will be about 10%, while the car can work much better in a more convenient mode for the driver. The electronic circuit will not experience stress when changing parameters, so this method is also considered safe for the machine.

What kind of tuning of the VAZ-2114 engine should be carried out?

1. If you want to improve its driving characteristics without causing much harm to your car, the best choice is reprogramming, or so-called chip tuning. The control of the VAZ engine of the fourteenth model is mainly dependent on the interaction of electronics - sensors and ECUs. By changing some settings to suit yourself, you can achieve a reduction in fuel costs, more streamlined engine operation at start and load, and optimal fuel supply through the injector. To do this, you will need a programmer that will allow you to repeatedly change the computer settings.
2. The second type of tuning will be the cooling system. Overheating is a problem that literally all VAZs of any generation have. So it's worth thinking about several innovations in the cooling system. One solution recommended here is to direct the coolant directly to the thermostat from the heater. To do this, a new pipe is soldered into the cooling system, and the pump hole is turned off. The work requires good knowledge of the machine, so it is not recommended for beginners. When upgrading the pipe, the engine temperature sensor will show several degrees lower than usual, and the operation of the car in summer will become more stable.
3. The VAZ-2114 engine mounts are part of the vehicle's support system. Thanks to these parts, the driver does not feel vibrations in the cabin. If you are going to add parts that will increase the weight of the engine assembly, take care to strengthen the supports.

We increase the power of the 8 valve VAZ-2114 engine with our own hands - myths and reality

It's no secret that in its standard, that is, in serial form, the engine does not develop all the power it is capable of. You can configure the firmware in a new way, but you won’t be able to significantly change the load curve without reducing the environmental class. You can buy a "racing camshaft" to install in place of the stock one. But then the firmware will have to be changed to accommodate the new phases... Let's consider what happens if we use only accessible tuning methods. Let's say right away that on the VAZ-2114 hatchback the increase in power can be 20% or even 25%, and we are talking about only 8 valves. There is no need to bore the valve channels.

Let's leave illusions in the past, and for this we watch one video.

An example of increasing the power of a VAZ-2114 engine

During the tuning, the 2111 (1.5 l) engine was modified.

Boring of seats along the internal diameter, which is equivalent to enlarging the valve;

Valve seats, VAZ 2111 engine

New cylinder head elements

Tuning timing gear

Our new engine remains “not plug-in” - the valves do not reach the pistons. When tested on a bench (the sensors were turned off), the result was not impressive.

Checking without adjusting the ECU

If you install the engineering firmware, you can select the parameters “from start to finish.” And then the picture looks better...

Torque graph after tuning is completed

All sensors, including the lambda probe, were connected in the latter case. We managed to get 96 “forces” at 5300 rpm!

How not to increase power!

• Do not attempt to bore channels. This operation can be performed in the absence of ball cutters, but in garage conditions nothing will work even with cutters. The bottom line is that the accuracy of the cutter installation is important - the error should not exceed 1-2 microns.
• As you can see, on the stock VAZ-2114 hatchback the increase in power was 24%, and this is without installing a “chandelier”, “improved exhaust” and other expensive elements.
• There is no point in buying a “racing camshaft” without having the appropriate tuning firmware.

What to do with engine 11183?

It is clear that a mandatory step in tuning the 11183 engine will be replacing the ECU. It’s simple: the standard M74 block cannot be flashed, but “January 7.2” is a good and time-tested solution. You will also have to abandon the “E-Gas” option, which means replacing the throttle assembly and receiver.

Everything I had to throw away

The intake tract parts were borrowed from the 2111 engine. A cable pedal was installed, and the engine began to look human.

Everything works well with the “January” controller, but standard firmware is not an option if the camshaft has been replaced. And it, in turn, has the following parameters:

• Release phase width – 104 ;
• Intake phase width – 109 ;
• Opening angle at outlet – 272 ;
• Inlet opening angle – 268 ;
• Valve travel (exhaust/intake) – 9.5/10.1 mm.

After installing the new shaft, the motor became plug-in. However, on the 2114 hatchback, increasing power almost always comes with a compromise. In this case, we had to sacrifice reliability. What's improved:

• Maximum torque increased by 14 N*m ;
• The power also increased – the limit of “90 horsepower” was passed.

By the way, any tuning leads to a decrease in durability. Make a choice.

Increasing the working volume of the cylinders

This is the most proven and reliable method to improve the acceleration dynamics of any car. The essence of the work on boosting the engine is very simple - you just need to bore the piston correctly, modify the intake manifold and change the crankshaft. But, unfortunately, this cannot be done without a special machine, tools, and especially abilities. The piston is bored using high-tech equipment based on clear calculations and in compliance with the dimensions. If the part is ground down by at least a few mm, it is not easy to expect any results from such forcing. the VAZ-2114 engine on your own

You can’t do it that way.

On the special 100, the craftsmen will quickly select the optimal crankshaft for you (the highest, in other words, lightweight), change it and correctly bore the engine pistons. In time, the process of boosting the motor takes approximately once. From a monetary point of view, you will have to spend 500 bucks at the cinema level to “bring the engine to mind.” Thanks to the reduced size of the pistons and a modified intake manifold, engine power

will increase almost 1.5 times. In other words, instead of the old 90 horsepower, we immediately get 135. And fuel consumption will not be economical. average, it will increase by 2-3 liters.

Method for increasing the power of an 8 valve engine with a split gear

The split, that is, adjustable gear was not used in the last project. It is better to install it on “non-plug-in motors”. Setting method:

1. The moving and fixed parts are marked with a mark, the same as on a standard pulley;
2. Installation is carried out in the usual manner, aligning the crankshaft and timing mechanism according to the marks (as when replacing a belt), you should also remember about the correct tightening torque of the belt;
3. If in the 4th cylinder the intake and exhaust valves are not open “to the maximum”, we carry out an adjustment: loosen the outer screws, and, holding the outer part of the gear, set the camshaft correctly. Tighten the fixing screws.

Split gear with retaining screws removed

Tuning parts, popular and not so popular

We have arranged all the elements in order of increasing uselessness:

Receiver with increased volume. After replacing the standard unit, there is an increase in output at medium and high speeds. But for the region of 1000-2500 rpm, it would be preferable to have a standard receiver.

Receiver with increased volume (shorter path)

Tuning throttle assembly

As for the exhaust tract, you can install a “4-2-1 spider” - it creates a vacuum in front of the valve that is not yet open... Torque and power are improved from this, the question is by how much.

Any “tuning” begins not with the engine, but with the selection of “gear ratios”... This advice is common, and it also applies to the VAZ-2108 and 2114 families.

Increasing the power and engine capacity of the VAZ 2114

The VAZ 2114 engine size and its characteristics changed and improved throughout the entire production period, from 2001 to December 2013.
The first batch of VAZ 2114 cars were equipped with 1.5 liter 8-valve injection units. After the modernization in 2007, new engines with a volume of 1.6 liters were installed on the “fourteenths”. New production VAZ-11183-1000260 engines received environmental class 3, Euro-3. The most powerful of all VAZ units was assembled and installed on the Lada Priora in 2010. The power of this power plant was 98 horsepower. A common feature of all engines of the VAZ 2114 model is that they are 4-stroke and have the same distributed fuel injection system. Fuel is supplied to the engine cylinders thanks to installed injectors.

Today, this method of powering engines is the most efficient of all fuel supply schemes. The engines have a standard, in-line appearance, and their camshaft is located on top. A closed liquid system is used to cool the units. Some mechanisms are lubricated with oil under pressure, others by spraying oil.

Engine design and its properties

Before we start talking about improvements, it is necessary to find out how this engine and its series differed from previous ones. The VAZ-2114 engine uses an injector as a fuel injection system, which is controlled by a computer system. Thanks to the installation of injectors, it was possible to significantly reduce fuel costs and generally increase the service life of the engine. Despite the good solution, the power of the power unit did not increase.

Now there are models with 8 valves with a volume of 1.5 and 1.6 liters, and also modifications with 16 valves with a volume of 1.6 liters. The first two design options are the most common and differ from each other in power; the 1.6-liter 8-valve engine has an increase of 4 liters. With.

The maximum power rating with the factory configuration of the 2010 Lada Priora is 98 hp. With.

This is the only way the power units of the entire fourteenth VAZ line can differ from each other. The architecture of all machines is approximately the same. Among the features we can highlight several non-standard design solutions:

1. The camshaft is located at the top of the assembly.
2. The cast iron cylinder block is a cast part.
3. Below the block are the main bearings, which are factory fitted, making them impossible to replace.
4. The injection system is an injection system, controlled using on-board electronics and a set of sensors.

Characteristics of VAZ 2114 engines

A very common engine model on the VAZ 2114 was an engine with a total power of 81.6 hp. With. with serial number VAZ 21114. This is an in-line type of power plant that uses an injection power system. The cylinder block is made of cast iron. The rotation speed of the power unit reaches 5200 rpm. For high-quality operation, the engine is filled with AI-95 gasoline.

Unlike its predecessor (VAZ 2111), in the updated VAZ 21114, due to the installation of an improved crank and an increase in the stroke of the piston system, the engine volume increased by 0.1 liters. The total volume of the VAZ 21114 engine was 1.6 liters. In addition, it has become much more powerful. The downside to the increase in volume was a decrease in torque.

The piston stroke of such an engine on a VAZ 2114 reaches 71 mm. The cylinder diameter size is 82 mm. Engine displacement varies from 1499 to 2114 cm³. Torque - 116 Nm/3000 rpm. Fuel consumption in the city reaches 8.8 liters, on the highway it is significantly lower - 5.7 liters per 100 km. Oil consumption - 50 g/1000 km. Engine weight 2114 - 127 kg.

If you want to have a faster option, it is better to opt for the one and a half liter VAZ 2111 engine. The reduced stroke of the piston system allows the engine to gain speed faster.

Maintenance schedule

To avoid having to carry out expensive overhauls of the Lada Samara 2114 yourself, you should follow the manufacturer’s recommendations for servicing the internal combustion engine:

If consumables are replaced within the recommended time frame, the operational life of the internal combustion engine will increase.

Selecting the number of engine valves

The selection of an engine largely depends on the number of valves installed. Early VAZ 2114 models were distinguished by engines with 8 valves. After 2007, eight-valve engines were replaced by engines with 16-valve heads. Valves in internal combustion engines are used to admit the air-fuel mixture and exhaust exhaust gases. Accordingly, the higher the valve capacity, the stronger and more powerful the motor.

It is easy to conclude that the gas throughput through a head with 8 valves is much lower than through a 16-valve head. Although 8-valve engines perform poorly at high revs, they produce excellent low-end torque.

An engine with 16 valves can pass more gases through itself, due to which the car accelerates faster. Unfortunately, this design also has disadvantages, the main one of which is the deformation of the valves themselves. 16-valve engines have not yet stood the test of time, so eight-valve engines are still considered more reliable.

When choosing an engine for a VAZ 2114, you must be guided by the following principles. A 16-valve engine (1.6 L) or an 8-valve engine (1.5 L) is chosen if high speed and high torque are required. With an emphasis on stable and powerful low-end thrust, the 1.6L 8-valve engine is the best option.

Where to begin? (if you have an 8kl engine)

8th grade The motor for 2114 2113 2115 is a development of the 80s. Accordingly, it is morally outdated, its efficiency leaves much to be desired. This is why, if you are interested in the idea of ​​tuning a car, the first thing you need to do is not install a turbo or shafts with a receiver, but you need to switch to 16v. Those. go to 16th grade. motor, because it is not so difficult and not expensive.

Why is it worth moving from 8th grade? for 16th grade

I will give a number of reasons:

– 16kl. the motor is more advanced, the efficiency is much greater than that of an 8kL motor

– already with the installation of a 16kl head, you will receive a significant increase in power

– further tuning 16 cells. the engine will give much greater returns than tuning 8 cells. motor.

Go to 16th grade. the motor, as mentioned above, is not that expensive. The cylinder head (cylinder head) in 2016 can be bought for about 3 thousand rubles. And in some cases - at the price of scrap metal.

Finding more detailed instructions for switching from 8 cells to 16 cells is not a problem.

Causes and repair of motor malfunctions

As already mentioned, according to AvtoVAZ, the maximum service life of the VAZ 2114 engine is 150 thousand km. With normal and timely maintenance, the engine can work longer. The standard operating temperature range is from 95 to 103 °C. An oil change should take place on a warm VAZ 2114 engine every 10-15 thousand km. When the first signals about a car malfunction appear, you must contact the station or find the cause yourself. The most common engine problems.

1. Floating engine speed. As a rule, this happens in new cars and at idle speed. If the car has no mileage, go for diagnostics; repairs should be carried out under warranty. The cause of the problem may be the idle speed control, throttle position sensor or vacuum unit.
2. The car engine stalls while driving (floating engine speed plus problems with the mass air flow sensor) - the causes of the breakdown are the same.
3. Uneven engine operation (troit). Cylinder compression measurements should be taken. If one of them has low compression, then the valve or head there has burned out. If the difference in measurements is small, then the pressure in the valves should be adjusted or the gasket replaced. If compression measurements do not show any deviations, then you need to check the ignition module.
4. The engine does not reach normal operating temperature. The reason lies in a faulty thermostat.
5. Noises and knocking noises in the engine. As a rule, the cause is poor valve adjustment. If the sounds get louder when you press the gas pedal, you need to go to a specialist. Problems may arise in the connecting rod or crankshaft bearings or in the cylinder pistons.

Tuning VAZ engines

Engine tuning is carried out for the reason that VAZ cars are simple and unpretentious to maintain, but the factory settings do not allow maximum use of the engine's resource. You can independently increase the power of the VAZ 2114 engine and increase its acceleration speed by using basic methods.

1. Increasing engine power by increasing engine displacement. With this effect, it is possible to increase up to 15 horsepower to the existing engine power.
2. Fine tuning of the fuel injection system. There are two main ways: replacing the factory engine power supply system with a more expensive one and replacing the carburetor circuit with a gasoline injection system. The advantages of the gasoline injection system are better mixing of fuel with air, which improves the combustion of gasoline and leads to a reduction in its consumption.
3. Installation of an aerodynamic air filter. The design of the filter is such that air passing through it experiences the minimum possible resistance and enters the mixer with less effort. An increase in power is possible by 5% with minimal effort from the car owner.
4. Adjusting the motor head. This method, like the previous one, is based on reducing the resistance to the movement of air flows in the places where the cylinder openings combine with the collectors.
5. Engine chip tuning. This is done by changing the settings of the electrical control unit for fuel injection and ignition system. Available exclusively for vehicles with direct injection engines.

When upgrading the engine of a VAZ car, as a rule, several methods of increasing engine power are combined simultaneously. The choice depends on what engine resource needs to be increased. You should refrain from wanting to increase power by more than 30%. If this is not taken into account, then the cost of maintaining the car will increase, which will “block” the effect of the tuning.

Tuning Lada Samara, is it necessary?

By asking this question, the public can be divided into 3 categories of people, 3 worldviews, and 3 options for answering the question. Let's start in order.

1. “Not needed” - people in this category are usually the most adequate people, they need a car for driving and nothing more. You need a car to go to work, to the country, on business, etc., i.e. a complete workhorse that should not take up any extra money. The majority of people are like this.
2. “Needed, but no money” - People in this category, students, young guys, “THE BASIN IS FLOWING.” They can only afford a little chip tuning and installing a zero-resistance filter, but sometimes it’s too expensive for them to fill up with 95. There are slightly fewer such people than the first category.
3. “I need it, and I do it” - such people are a minority, 1% of all car owners, a completely separate category of people who don’t mind spending 50 and 10 and 150 and 200 rubles. on their fourteenth or thirteenth. It is this category of people who constantly sit on forums, argue with each other, actively discuss something, etc.

Asking the question, “Is it necessary to tune the Lada Samara?” everyone finds an appropriate answer for themselves and classifies themselves either into one or another category of people.
