Tuning VAZ 2115 - photo, do-it-yourself tuning, interior tuning, engine tuning of 2115

No matter how perfect the factory car is, there is hardly at least one owner who would not like to make at least a small modification to the design or appearance. This is especially true for cheap domestic cars, in which almost every detail requires, if not alteration, then modification for normal operation. VAZ 2115 is also no exception. And although it has proven itself to be a fairly reliable car, few people use it without modifications and additional investment of money. Let’s figure it out together how to properly invest the minimum amount in Samara with maximum results.

Do-it-yourself tuning of VAZ 2115: interior, trunk, engine

Appearing better than you are is actually easier and cheaper than becoming better. This question is always relevant when it comes to tuning budget cars with high mileage. Nevertheless, this is not forbidden to anyone, and using the example of a stale VAZ 2115, we will trace some of the trends followed by tuning fans. In our realities, car tuning has two branches of development - progressive, aimed at improving the technical characteristics and comfort of the car, and dead-end, which comes down exclusively to external changes, according to the tastes of the owner. Let's mix these two concepts and see what steps can be taken to improve and refine the appearance and parameters of the VAZ 2115.

Body tuning

External tuning

It is quite natural that serious DIY tuning of a VAZ 2115 cannot be done without sophisticated equipment, so we will consider the most accessible and inexpensive options. We will try not to cause serious damage to the appearance of the car, since the work of designers and constructors must be respected. If you don't like the car so much from the hood to the rear lights, then it wasn't worth buying it. Based on this, we will try to fall in love with the unsightly appearance of 2115, and try to transform it. There are things that a car should be forgiven due to its advanced age - bumpers, simple optics. You can replace everything, but it will be a completely different car and a completely different investment.

One of the most popular accessories are hood deflectors, which, in principle, are designed to improve the aerodynamics of the car and at the same time drive away insects from the windshield, for which the element is affectionately nicknamed a fly swatter. Let's look at how well this thing suits its purpose in a little more detail - it attaches very simply and can be removed just as quickly if necessary. Its aesthetic value remains on the conscience of the owner, since there is no need to talk about exclusivity. Every third car has such a black stripe on the hood. From a practical point of view, there is no use for a fly swatter. The insects have been knocking on the glass and continue to knock. It protects from small stones and sand only that part of the hood that it covers, and the aerodynamic performance of the car as a whole deteriorates by 3%. This was shown by blowing in the wind tunnel of the AvtoVAZ Technical Development Directorate. Well, three percent is nothing. For the sake of such beauty it is worth sacrificing them.

But in the same wind tunnel it was found that the fly swatter increases the lift coefficient on the front axle of the car by 19%. And this is already dangerous, especially at high speeds. In addition, the plastic part tends to vibrate when moving, and sand and dust are sucked under the leading edge, like a vacuum cleaner. As a result, the paint on the hood is rubbed down to metal, which does not indicate the absolute benefit of this aerodynamic element. Various deflectors were blown in the pipe, which are hung on the windows of the front doors, as well as a deflector for blowing the rear window. The rear deflector is designed to clear the rear window from flows of dirt and splashes, but test results showed that the use of the rear deflector did not affect the aerodynamic characteristics of the car in any way, but the lift coefficient of the front axle increased by 17%, and the downforce of the rear axle by −15. 5 kgf turned into lifting - 35.3 kgf. At a speed of 144 km/h this can lead to loss of control, especially on wet roads. And this is with a standard rear wing on the trunk lid. Draw your own conclusions.

The heart of the car

We increase the efficiency of the stove on the 2115 VAZ | Advice for car enthusiasts

For many large car owners, the problem is the efficient operation of the heating stove.
Cases when it produces the necessary heating for the interior and windshield, if you survey car enthusiasts, are very rare. To identify the reasons, you can use the services of a specialist to try or fix everything yourself. First of all, we put a container with a large upper area under the bottom and pour antifreeze into it, after that, and then what, we get to work. The first thing we check is how aligned the outgoing heater nozzles are with the holes on the dashboard. As practice shows, incompatibility will definitely be discovered, which can be the cause of ineffective heating. This factory defect can be eliminated by filing, but to do this it is necessary to remove the dashboard, the stove itself and disconnect the radiator.

The VAZ 2115 radiator is identical to the models installed on other VAZ models. Modifications may differ slightly, but according to the principle of their operation, they are all the same. The presence of turbulators on the radiator improves the rate of heat transfer and ensures heating uniformity of the heat exchanger.

Before disassembling the heater, you need to check the space where the radiator is inserted. Due to the influence of constant high temperatures, very often this space becomes deformed. As a result, there is no necessary tightness, on which the efficient operation of the heater directly depends.

The tightness is easily restored using foam rubber or bitoplast. If there are no other defects, then reassembly can begin. fastenings The places of the dampers are lubricated with lithol, and all connection bodies must be treated with sealant. In some cases, there may be increased noise when the stove operates at high speeds due to the impeller. The problem is eliminated by simply winding a piece of wire around the rim of the blades.

The operation of an inefficient heating stove may be in which a stocking is installed on the fan casing. The main purpose of the casing is to protect against all kinds of debris. The casing can become clogged in a fairly short period of time and in this case there will be no benefit from it.

If the troubleshooting of problems associated with the discrepancy between the holes of the exhaust nozzles and the holes on the dashboard is carried out correctly, then the temperature in the cabin when the heater is running will be significantly lower.

will increase with the temperature inside the car; it is also important to maintain heat in your own garage. Garage roller shutter doors from the Aluminum Systems company will perfectly retain heat in your car’s home.

Tuning the VAZ 2115 engine

It is impossible to embrace the immensity, therefore it will not be possible to tell about all the tricks for increasing the power of the VAZ 2115, however, we will briefly outline some points regarding supercharging. Its possibilities are not unlimited, but it can give a good increase in power if the car’s engine is assembled perfectly. The fact is that by adjusting and fine-tuning all the engine parts with your own hands, the increase in power can be from 15 to 22%. Tested by practice. Without any surgery or chipping, simply by bringing all adjustment dimensions, gaps and planes to factory standards, you can increase engine power. It's not as easy as it seems, but if you have the time and desire, you can do it yourself.

To do this you need:

balance the pistons by weight so that the difference between them is no more than 2-3 g
;
balance the crankshaft, flywheel and clutch assembly to the maximum possible value
;
eliminate all irregularities and differences in the exhaust manifold, where it mates with the cylinder head in the 1.5 i engine, and if the engine is also carburetor, then do the same operation in the intake manifold
;
select piston rings with the minimum permissible clearance on the piston individually
;
grind all the valves in place, especially for a 16-valve engine
.

The list of improvements is far from complete, but it gives an idea of the scope of work, which leads to an increase in power and improved engine performance in all modes, without making virtually any changes to the design. Nobody will do such fine-tuning at the factory, it’s not manual assembly after all. That's why horsepower is lost on such seemingly trifles.

Now about the boost. Indeed, several years ago there was a development to install a compressor on the 1.5 i injection engine, but not a turbo, but with a drive. Unlike the common turbocharging, such a turbine is driven by a mechanical drive and is capable of increasing the power of a one and a half liter engine to 120 l/s. True, if you overdo it with turbine pressure, the cylinder head may burn out and the partition between the cylinders in the block itself may melt. This requires a very precise calculation, but the result justifies the work and investment.

heater Modification of VAZ 2108 - 2109

With the onset of the cold season, I have already written a series of mini-articles about tuning VAZ heaters. Let's remember: this is the post “small tuning of the VAZ heater”, the post “heater noise VAZ 2107-2101”. Now it’s the turn of the Actually family...

Samar, what's the problem? Very often there is such a thing that the heater of a VAZ 2109 - 2108 heats up, but not very much, at idle it generally blows cold air... As the speed increases, the situation improves, but not much... Is this a familiar situation? Let's try to figure it out.

There are reasons for low heater performance

Samar such assumptions/reasons:

An old stove radiator clogged with debris and scale.
The thermostat is faulty and keeps the temperature below 90 degrees.
Air traffic jam (unlikely option, but sometimes it happens).
system in the penetration of heating air, which passes through the cracks.
The presence of a large amount of debris (mainly insects, leaves) in the heater housing and preventing the passage of free air through the radiator.
Well, the reason is very banal - low coolant level.

How are these problems solved? The first problem, the formation of associated scale inside the radiator, can be solved by replacing only the radiator. Here, of course, you can offer the option of unsoldering and cleaning the radiator, but from my bitter experience, I will say that this idea is pointless. Thermostat Fault is a synonym for the word “replacement”. We’ll talk about solutions to other people’s problems with the heater next.

Tuning VAZ heater 2108 – 2109

My advice to you before dealing with others is to try and pay attention to the heater radiator when making alterations. Sometimes the radiator is so dirty that there is no talk of passing any kind of coolant. Perhaps it has simply outlived its usefulness and is needed further. replace, what I would like to pay attention to is the pump (coolant pump). An improved and more productive option is Luzar Turbo and TZA Premium. Luzar There are two pumps 21114 for Turbo:

species-1307010 (LWP 01084), it is equipped with VAZ cars 2108 - 2115, with an engine having an 8-valve cylinder block head.
The pump 21124-LWP (1307010 01124) is equipped with VAZ cars of the tenth family, Kalina, Priors, with a 16-valve head, which were produced before 2008.

After reading a little about the manufacturer's data, we can answer the question - why is Turbo Luzar better than a regular pump?

The manufacturer claims that this pump has increased performance, equal to (on average) 12.5%, while the engine does not lose power. And consequently, the higher the speed of coolant flow through the system, the more stable the engine temperature.
The average engine temperature is also reduced, which has a positive effect on durability.
indicators improve with the so-called “thermal shock” - stopping the sudden circulation of coolant, this is observed when the speed is dropped.

The difference in the design is the impeller, which is made of stainless steel sheet and equipped with a large number of specially shaped blades.

Another important result in favor of Luzar is that according to tests carried out in the magazine “Behind the Wheel”, it took first place. Reviews are generally positive, you can try installing it.

Interior tuning

One of the most favorite types of amateur tuning. There are such rare variants here that it is impossible to describe them in words. There are fans of decorating the instrument panel with a mass of arrow indicators, the number of which exceeds the number of sensors in the engine. This modification looks fun, but it is of no use.

Fans of sports style especially love such instrument excesses, although you rarely even see a speedometer in real sports cars.

A truly well-executed car interior should not put the driver and passengers in secondary positions. The main thing is that the cabin is comfortable and safe, and the number, color and brightness of LED lights is a matter of taste. Respect your car, and it will definitely reciprocate.

Experts' opinion

Michael. I am engaged in the professional provision of services for upholstering the interior of a vehicle with new fabric. I would like to note right away that quite often I come across a situation where I have to redo it after trying to do the work myself. In this case, costs only increase, since the previously used material becomes unsuitable when attempting to complete the work independently.

Igor. I am involved in installing air conditioning systems on cars. An air conditioner is a complex and quite expensive piece of equipment that must be installed correctly for long-term operation. You can install it on a VAZ, but the work is quite difficult due to the lack of this option even on expensive trim levels. Therefore, the cost of the service is high.

Grigory. Do you want to increase your comfort in your car and travel long distances without feeling tired? Seats with lateral support are designed specifically to solve the problem at hand. You can buy them with delivery, installation will not cause much difficulty.

Denis. I can consider myself a VAZ fan, since in all my driving experience I have only driven cars from the domestic auto industry. After much thought, I chose 2115 tons for myself and did not regret it at all - after modifications, the car does not look like the money that was invested in it.

We are finalizing and improving the VAZ 2115: interior tuning

Main stages of work

Editing a car interior usually involves several main steps, which include:

Disassembly. At this stage, interior elements should be removed. In this case, it is necessary to exercise maximum care: some factory elements will be required in subsequent work, the rest can be sold.
Soundproofing. Everyone knows that sound insulation of domestic cars is often almost completely absent. In this regard, when working with a VAZ 2114, tuning the interior must necessarily include an insulation stage. Thanks to this, during the cold season the room will become both quieter and warmer.
Modernization of the dashboard. Another big drawback of VAZ 2114 cars is the poor quality of the front panel - the materials used, the difficult to read instrument cluster, the unattractive appearance - all this indicates the need for modernization and replacement of elements.
Upholstery. The easiest part of the job. There is quite a large selection of seats on the market to suit every taste, ready-made side panels, even upholstery are easy to choose to suit your needs and wishes. It should be noted that you should not change the seat upholstery, since their quality is unlikely to allow you to adequately endure this procedure and continue to serve. It is better to make a complete replacement with ready-made elements.

The listed stages are the main ones. Now we can look at each in more detail.

How to invest money in a VAZ 2115 correctly

VAZ 2115 is an attempt to extend the assembly line life of the already classic ninety-ninth. Although everyone understands perfectly well that the design of the car began to become obsolete even during its assembly line life, attempts to bring the design to at least some acceptable technological minimum will always be made. And all this requires certain investments and each additional piece of hardware has its own price.

Therefore, we will figure out what is worth investing in first and what can wait. So, for example, external tuning, installation of plastic body kits, bumpers, spoilers and aerodynamic skirts do not make any sense until the chassis, body, engine and at least the interior are brought back to normal. And there is where to invest money.

Chassis and steering tuning

Let's start with the fact that, by modern standards, the car's chassis already needs certain improvements, especially since all the necessary components are available for this. We do not advocate installing expensive Bilstein shock absorbers on Samara, but some less expensive work can be done.

Installing power steering on a VAZ 2112 is a completely adequate step. And it will cost at most a couple of tens of thousands. Even cheaper is installing electric power steering from Priora. For this you will need:

the electric booster itself;
plan-washer adapter;
additional cardan;
steering wheel cover from the new 2112 models;
installation wires with connectors.

An electric amplifier costs about 17 thousand in a store, but you will be confident that the car is controlled adequately, and less effort will be spent fighting the rack.

Installation of electric window lifts

The car in question was also produced with a mechanical window lift - a thing of the past that still haunts the domestic auto industry. In order to make it convenient for passengers and the driver himself, electric lifts should be installed.

You can carry out such an upgrade yourself. This is due to the fact that the lift is purchased disassembled. You can choose a design that was installed on a more expensive configuration of a particular model, which determines ease of installation.

Problems can only arise when connecting the mechanism to a power source, since for this you will have to create chips and lay out the wiring yourself.

Problems may also arise with the output of the glass control unit. As a rule, the buttons are located directly on the door and can be duplicated on another panel. Therefore, when purchasing a window lifter, you should also select handles with window lifter control buttons.

When tuning, it becomes possible to duplicate the control unit on other panels, which will increase the comfort of performing this function.

Refinement of the brake system

Another nice addition to the design of the old 2115 will be tuning the brakes. Namely, installing rear disc brakes. No one will argue that disc brakes are much more efficient than drum brakes. Even if the owner does not intend to conquer the Nuremburg Ring, but simply move comfortably around the city, then the maintenance and operation of disc brakes will be much more pleasant and the ride safer.

As a rule, the 2115 is equipped with front disc brakes, which can easily be found used. This will further reduce the cost of the design. The only thing you will need to buy or order additionally is the washer plate to which the brake caliper is attached. It costs about 400 rubles each. Installing disc brakes doesn't even take much time. You will only need to sweat with unscrewing the soured fasteners and introducing a hand brake into the structure. Although they also sell special kits for this, ready for installation.

Climate change inside the cabin

Another modification is the installation of air conditioning. Over a couple of hot years, many breakdowns occur with a significant increase in temperature in the cabin. On sale you can find small car air conditioners that can be installed on a VAZ. With such a modification many difficulties arise.

To begin with, you should pay attention to the fact that the design does not provide a compartment for the air conditioner, which is large enough. Therefore, installation involves replacing the front dashboard - often sacrificing the glove box, using its space to install an air conditioner.

Also, do not forget that for this design to work, air flow is necessary. In this case, the air must be filtered, since the ingress of debris causes a significant reduction in the service life of the structure in question. In order for the air conditioner to work, an energy supply is necessary, another reason to entrust the work to real professionals.

Engine modification

It will not be possible to defeat the prehistoric engine with a little blood. This requires an integrated and thoughtful approach. It doesn’t matter at all whether the injector is installed on a tag, or there is an old carburetor there. The essence of the ancient engine does not change. Suffice it to say that after doing a whole series of rather complex work:

installation of forged pistons, precise adjustment of their weight;
installation of T-shaped valves;
replacing the camshaft with a shaft with changed phases;
installation of a split camshaft drive gear;
boring and polishing of sleeves;
installation of a tuned exhaust system;
modification of the cylinder head - installation of wear-resistant valve bushings and oil nozzles.

This whole complex will take at least 50 thousand, and will give a maximum increase in power of 15-18 forces. Moreover, both fuel consumption and engine life will change. Therefore, it is worth considering whether it is necessary to pay that kind of money for 15 additional forces and repair the engine every 50 thousand km in the best case.

As for the external modification of the VAZ 2115 tuning with your own hands, a photo of which we presented on the page, it’s up to everyone to decide and consult first of all with a bank card.

Tuning headlights, interior modifications, additional work on the body - all this makes sense only when the 2115 steers and brakes normally. Tuning inexpensively and with pleasure, good luck to everyone!

Types of tuning

One of the most popular types of tuning is changes in body kit. But this is also the most popular option, because the dynamic performance of the VAZ 2115 is relatively good. You can replace the bumper yourself, and there are even several methods of dismantling and repair. However, the owner of the VAZ-2115 should try to ensure that such a replacement does not affect the ground clearance.

If you tune the body kit, then the rear of the car should also be changed, but this option is not so common. The fact is that replacing the rear bumper radically changes the appearance of the rear of the VAZ-2115, which is why the vehicle becomes like a “medieval steam locomotive.”

There is also tuning:

doors;
windows;
trunk;
roofs;
hood;
lights (front and rear).

Additionally, overlays can be installed. In general, almost everything in a car can be replaced or improved. The main thing is not to break it and not to reduce safety indicators. Special attention should be paid to the so-called technical type of tuning.

Technical tuning

Technical tuning involves changing engine components to improve its performance and increase dynamic performance. Despite the fact that the 8-valve engine on the VAZ-2115 is already considered quite successful, owners regularly ask specialists to make a number of changes to speed up its operation or extend its service life.

Engine chipping

Many car enthusiasts are interested in this type of technical tuning. This option allows you to programmatically change the “brains”. Basically, it is designed to;

increase traction at low speeds;
reduce fuel consumption;
use low octane gasoline.

In some cases, sports options for inserting chips are possible, which increase the engine power to a maximum of 5% of the existing one.

Change of cylinder and piston

Another option for improving engine performance is tuning the piston and cylinder groups. In this case, we are talking about increasing the volume of elements, as well as the possible replacement of the crankshaft or the use of oil of a different viscosity. Thus, the operating speed of the engine increases, which affects its power.

Transmission tuning

If you try to increase the power of the engine, this will lead to an increase in the load on its other components. The transmission can especially suffer, and therefore it also requires some changes, or rather, a complete rework.

Upgrading the transmission helps improve driving performance. In case of tuning, the VAZ-2115 will take turns with a large radius, and maximum concentration will be required from the driver.

Additionally, during transmission tuning, specialists change brake pads, linings and brake boosters themselves, because a car with high power will need to be stopped somehow efficiently. Install the boosters by doubling the brake pedal pressure.

And at the very end...

There are a huge number of optimization options, many articles have been written about this, many videos have been filmed on the Internet, but this topic is inexhaustible. There will always be masters who will invent something new and original. It’s not without reason that the cost of tuning some copies can exceed the cost of the car by 2 or even 3 times. In general, do tuning, show your individuality, but do it wisely. Good luck.

Interior tuning

Finally, another option for modernizing or improving the appearance of the VAZ-2115 from the inside is interior tuning. In this case, the main vector is the owner’s imagination and the capabilities of a service station or other organization. The photo shows an approximate version of such changes.

Reducing sounds

During operation, the car makes a lot of sounds (especially if we are talking about the production of AvtoVAZ), and because of them it is not always comfortable for the driver and passengers to be in the cabin. Thanks to the so-called noise reduction, you can reduce the amount of sounds entering the cabin or remove them altogether. At the same time, the car owner himself can carry out such an improvement if he treats the work responsibly and does everything carefully. One way to improve sound insulation is to replace seat upholstery and door trims.

Tuning chairs

Changing chairs means not only repairing or reupholstering them, but also expanding their functionality. For example, some VAZ-2115 owners ask for heated seats or built-in acoustic speakers.

Replacing the speaker system

Another way to significantly change the interior of a vehicle is to install new acoustics. Good sound in a car is the dream of many car owners. The standard acoustics in the VAZ are, to put it mildly, of low quality. Also, don’t forget about the radio that plays tracks.

It must also be of high quality, since otherwise installing expensive acoustics will not lead to improved sound. Replacing the speaker system should be carried out taking into account the information below:

1. In order for the sound in the car to be surround, you should install several additional speakers at once. At the same time, you can choose high-quality tweeters that do not have high power. It is better to install several low-power tweeters than one powerful one. When using a high-quality radio, the sound will be distributed across channels, creating a truly unusual effect.

2. It is best to install the acoustics at the time of reupholstering or insulating the interior. This is due to the fact that new tweeters will need seats. They can be made in doors and other finishing elements.

3. No acoustic system is complete without a subwoofer. It is responsible for the bass that tweeters do not reproduce. This acoustic element has quite large overall dimensions, which makes it difficult to choose a place to install it.

4. Do not forget about the correct placement of the wiring and its fixation.

Sidebar: Important: Complex speaker systems require the installation of an amplifier, which is also supplied with power. Therefore, as in the case of interior upholstery, the work of installing acoustics should be entrusted to professionals in the field of activity in question.
