Tuning VAZ-2108: just not to take off

Volkswagen GTI und Volkswagen Golf I GTI

For now, let's remember the past. 1974 Volkswagen launches the first Golf - an urban hatchback for every day, equally suitable for both a lawyer with a collection of colorful ties and a housewife puzzled by the purchase of fresh jam for pancakes. But the Germans realized that these were not all of their clients, and went further, releasing the Golf GTI in 1976. It was an original car, which, in addition to its pleasant appearance, had a fairly powerful engine and a modified suspension. So the Golf became a real icon - it painted a stupid smile on your face when accelerating and handled like a kitten chasing a flashlight on the home carpet.

So, before us is a VAZ-2108 produced in 1996. This car is quite good by the standards of the domestic automotive industry. But is it capable of processing 350–400 hp, which are wrapped in a twenty-year-old body? Initially, the G8 had 1.1–1.5 liter engines. To obtain power 7–8 times higher than the calculated factory figure, a 16-valve engine from a VAZ-2112 was installed under the hood, which was upgraded with other pistons, cylinder head, valves and much more. A huge Subarov turbine, complemented by an intercooler, instantly increased the power to 200 horsepower.

Roses... and thorns

This is where the problems started. The list of them is so large that if I wrote them all, the editor would be put to sleep trying to highlight the main ones. Let me just say that on the way to the finished configuration, the motor shattered into pieces six times! And a couple of times literally. It can be compared to a cat using its last, ninth life. Today the engine is almost ready. But custom-made for 80 thousand rubles. The cylinder head will already seem like a farce given the fact that the car was originally purchased for 100 thousand.

Improving car performance

By tuning a VAZ 2108 with your own hands, you can slightly improve the technical parameters of the car. In this case, the emphasis should be on replacing brake discs. Discs with a larger diameter are more efficient. Therefore, instead of traditional 260 mm components, it would be more advisable to choose the 360 mm option.

You should definitely put your hand to the exhaust pipe, significantly increasing the diameter of the muffler. In this case, you will have to work hard on the system in order for the impressive outer shell to acquire practical application. The best option is to replace the factory pipe from the manifold to the muffler with an element with a larger diameter. However, it should be selected strictly taking into account the technical capabilities of the car!

A pipe that is too wide will slow down the exhaust gases, which will eventually affect the vehicle's control system. At the end of the work, you need to pay attention not only to what is located on the body of the VAZ 2108, but also under the hood, namely, to the engine. You can force it in several ways that produce the same effect:

Boring cylinder blocks. The labor-intensive part of this process is boring, which can take an inexperienced car enthusiast several days. Once the process is completed, all that remains is to purchase the appropriate pistons and rings.
Replacing the crankshaft. This method is considered quite expensive, because during the tuning process the master will have to purchase a new shaft with a large crank radius. And this, in turn, will entail additional costs for the purchase of pistons, cylinders and rings.

Tuning your favorite car can be done ad infinitum, eventually completely replacing its contents. At the same time, it is important to stop in time, because such drastic changes may simply be unjustified. It is recommended to take photos before and after each change in order to really compare whether the car has changed for the better.

A piece had to be cut out of the already flimsy front end.
As a result, the “walking” spars simply began to shake at high speed. The problem was solved by installing a powerful subframe and spacers. A piece had to be cut out of the already flimsy front end. As a result, the “walking” spars simply began to shake at high speed. The problem was solved by installing a powerful subframe and spacers.

Next, the construction process tripped over the gearbox. Or rather, the lack of a suitable transmission. The VAZ gearbox can withstand up to 200 horsepower, but not 400, to which the engine was eventually accelerated. During the construction process, the gearbox was literally torn apart several times, and after opening it, inside there was a mess of gears floating in oil. The owner changed them once a week - I'm not exaggerating at all.

In the end, it became obvious that we needed to look for a “donor.” It was the legendary rally Lancia Delta Integrale. Having installed its box on the “eight”, all that remains is to find the wheel drives and the rocker. And if with the rocker everything was quite simple (it came from the Mitsubishi Lancer Evolution VIII), then about the drives I had to think twice. And what do you think? Drives from the same "Lancia"? Or maybe from Evo? Again, bypassed, because they are made from army (!) torsion bars. They took a piece of suspension from a combat armored personnel carrier and made drives. It's like making a New Year's cracker out of a hydrogen bomb.

Tuning the interior of the VAZ 2108

Modern tuning includes updating seat covers, gear shift knobs, and installing a music system. In general, interior tuning is a real creative process where there are no limits to human imagination. Of course, it is advisable to worry about sound insulation. The overall noise level is an important indicator of the comfort and coziness of the car.

Using materials such as vibroplast, modelin or bombs, you can make additional sound insulation. First, you need to remove everything unnecessary that interferes with your work. After this, the interior is cleaned, washed and thoroughly dried. Next, you can apply soundproofing material. The soundproofing material must be completely dry and only after that the interior is put back together. Make sure there are no “extra” parts left. The seats in the car can be replaced with sports ones. They are quite comfortable and have a fixed fit.

Perhaps some people will not like the fixed position, as it loads the spine. But technology does not stand still and you can purchase universal seats with additional functions. This includes various vibration massagers and built-in fans. Among other things, you can replace the upholstery using genuine leather. This upholstery will look very stylish and solid. If funds for expensive leather are limited, as an option, you can use tweed that matches the body color. Don't ignore the dashboard either. The panel can be upholstered with any material, adding originality and exclusivity to it. It wouldn’t hurt to touch on the lighting. Neon or LED lighting looks very stylish. Also, the steering wheel, gearbox, power windows, floor mats, phone holders and the like can be modified.

The miracles of transformation did not end there. The Gazelle cooling radiator has migrated to our G8, which does its job perfectly. There is also an oil cooler - its presence is vital on a sports car of this level. Even the gas tank is tuned - it’s a 20-liter plastic product with a system of anti-drip curtains, which prevent the gas pump from being fed with air instead of gasoline when cornering. In addition, the plastic solution is lighter, and the struggle when building a sports car is for every kilogram. “Nutritionists” recommended R17 forged wheels, which the owner purchased from a racing team in Tolyatti.

Let's take off!

Next is the body. Its refinement is aimed at improving rigidity and aerodynamics. It’s good if at the same time you can make the car beautiful. Spacers and subframes are required. But this is not enough. The front bumper directs air flow to cool the front brakes. Of course, we also worked on the bottom. It was completely cut out and sheets of thick corrugated aluminum were installed. As a result, the bottom of the body is now perfectly smooth, which facilitates the passage of air flow, which is also divided by the rear diffuser so that lift does not appear at high speed. In order for the body to withstand the colossal loads that it experiences, a bolted safety cage was assembled in it, which, even if the maximum pressure is exceeded, will not burst, but will bend slightly. Its presence is difficult to overestimate, given that the power is so abundant that the wide wheels slip even in third gear if the asphalt is even a little wet.

Tuning VAZ 2108 – what to improve, how to make tuning unique

Chisel. And nothing else. This is what the VAZ 2108 was called at the dawn of its almost undivided reign on the territory of the USSR and then the CIS. The peculiar angular design, which was in fashion in the mid-70s, reached our country only in 1985, when eights began to actively appear. The public stubbornly did not accept the new product, so ossified conservatives, accustomed to classic Zhiguli cars, gave it an offensive mechanical nickname.

Relevance of tuning VAZ 2108

By the beginning of the 90s, the car had become almost popular, and the nickname began to be forgotten. Only there were more and more eights, and everyone wanted to highlight their beauty in a special way. Since at that time there were no special opportunities for full-fledged tuning, it turned out something like this:

Not a particularly rich selection, as can be seen from the photo. Very soon there were more improved eights than stock ones, and then the plastic tuning industry slowly began to develop.

It consisted exclusively of fake and sometimes ridiculous and comical body kits, massive spoilers and fake air intakes. Now there is enough such goodness too.

As you can see, they also didn’t delve too deeply into stylistic subtleties, but that wasn’t necessary. The first factory tuned car can be considered a V8, prepared in class B for rally racing.

VAZ 2108 Eva

The preparation of the car was carried out in factory conditions, but not in Tolyatti, but in Vilnius, at the VFTS plant. It was an experimental facility to prepare stock cars for motorsport. With the light hand of the outstanding Lithuanian rally driver Stasys Brundza, the Vilnius Vehicle Factory began assembling first the 21011, prepared for the Group B rally, and then the VAZ 2105. The Eight became the last joint project of this enterprise with VAZ, but if we are talking about tuning, then this something to look up to even now. First, a couple of photos of this car.

It's 1986, there is a complete shortage of hardware and resources, and the Lithuanians managed to produce a high-quality sports car, almost at the level of world rally stars. This car you see in the photo is just a shell of the factory eight. Lights, doors and other little things. The engine is a great example of ingenuity from poverty. A block from 2106, bored to 1860 cc, Lukas fuel injection, turbocharging - all this produced about 300 horses.

The car had a mid-engine layout. That is, the engine was located behind the pilot’s and navigator’s seats, and the drive, naturally, was rear-wheel drive. But the all-wheel drive Eva S-Proto was being prepared for release, but one annoying detail prevented it from going public - the FIA banned Group B, and the project remained unrealized.

Amateur tuning VAZ 2108

First of all, a car enthusiast begins to improve his eight, naturally without any knowledge or skills in this matter, with external tuning.

The radically improved eight must have body kits. The more cheap plastic used for the body kit, the more powerful the car will be.

Laboratory tested. And a cheap film, which imitates cheap carbon fiber, adds 1.76 horsepower for every square centimeter. Believing in this, amateurs achieve amazing results in the art of decorating fairs and folk festivals.

Particularly pleasing are the color schemes, which directly affect aerodynamics. The brighter your figure eight, the lower the drag coefficient. Even the air gives way before such colors.

Tuning the interior of the VAZ 2108

The VAZ 2108 has, in principle, a good interior, which can be considered a model of modesty and asceticism. But today there are plenty of opportunities for even Ferraris to bite their lips until they bleed, seeing the number of instruments that are embedded on the dashboard.

Elite varieties of leatherette are especially popular. The most fashionable this year are blue and red. The color of fire and the color of water. To completely ruin the interior of a car, in no case do you need to take into account any design laws - the brighter the better.

Furs are a separate branch of amateur interior design. Look how cozy and tidy the interiors of the eights have become, generously trimmed with expensive furs.

Backlight. This point also deserves a separate discussion, but if you don’t know the limits and don’t have basic taste, then driving such a car will become torture.

Love your eight. She deserves to be reckoned with, she has her own style that will break through even the deepest improvements.

Therefore, before you start tuning the VAZ 2108, think about whether you will harm it, your one and only eight. Tune with your soul, and good luck on the roads!

Under the aluminum floor there is a homemade exhaust routed on two sides - an original solution in the style of a Dodge Viper.

For safety reasons, a fire extinguishing system was installed in the cabin, and the brakes were modified - front discs from Lada Kalina Sport, calipers from Mazda RX-7. The rear brakes are almost standard front discs from the VAZ-2112, only with perforations. Literally everything had to be modified, because any factory part can become a weak point, so it is necessary to create a safety margin.

The result is the wildest dynamics. The best acceleration to 100 km/h in hard mode is given to the “eight” in 4 seconds, and the maximum speed is limited to approximately 270 km/h! The time required for the 0-200 km/h sprint is even more amazing - 11-12 seconds! Judge for yourself: with a car weighing 900 kg, it has a power/weight ratio of 445 hp/t. And this opens up the possibility of drag racing with opponents such as the Audi RS6 or BMW M3. I was driven in this car a couple of times, and I must say that after the ride I almost started stuttering. Monstrous impressions. The acceleration is so lightning fast that even a mute person will start swearing obscenely from the overloads and vibrations running across the floor at speeds over 200 km/h.

Tuning VAZ 21083 with your own hands

VAZ 21083 is one of the most famous car models for tuning in the former USSR, representing the first mass-produced Soviet sports car. I just want to make its chopped, swift lines more sporty, and for this you need to do the tuning of the VAZ 21083 with your own hands.

External tuning of VAZ 21083. Most external tuning kits allow this to be done without problems. But what should those who do not have money for expensive parts do? The answer is to do everything yourself. When externally tuning a VAZ 21083 car, car owners want to reduce air resistance (while increasing downforce) and give their car a modern appearance. Everyone chooses aesthetic innovations according to their own taste, but aerodynamic ones must be chosen strictly according to the rules. The exterior of the VAZ 2108 is very well designed and the drag coefficient is too low for cars that have been on the assembly line for 20 years. It is not possible to improve the aerodynamics of a car with just a spoiler, of course, unless it is a huge add-on over the tailgate. To create additional downforce, it is best to use a new bumper (front and rear), which will not only increase the pressure of the car to the road, but will also “eat up” several centimeters of ground clearance. You don't need to install just the front bumper. If you have already started to modify it, then you need to use all the means: additional air intakes, sills, spoiler, bumpers, deflectors, fins on the hood. All of these exterior decoration components are both aesthetic details and useful additions. For example, the deflector reliably and quickly relieves all owners of VAZ 21083 cars from this problem, such as rear window contamination. The deflector is a small metal strip installed on the rear of the roof. It will not only eliminate the problem of dirty rear window, but also increase air resistance. But in this case, the lifting forces are distributed worse among the axles, which leads to not very good handling. Do-it-yourself tuning: improving car handling. Handling can be easily improved by installing a spoiler. Almost all components of the external body kit that you make with your own hands will not affect the aerodynamics, because all the nuances of the car’s operation are not taken into account, and most importantly, they are not purged in a wind tunnel. The front and rear bumpers do not significantly affect the weight distribution of the car, since they are made from lightweight plastic or fiberglass. The same applies to the spoiler and sills. Therefore, you can safely create an individual appearance for the VAZ 21083 car. New rims may significantly affect the car’s handling. Many VAZ 21083 owners first of all “shoe” their car with light alloy or titanium wheels, which are lighter than forged ones. Consequently, the front and rear suspensions are unloaded and the behavior of the car will be unpredictable. Then you need to seriously rework the entire chassis of the car and its steering.

The spartan interior does not even provide an ignition key.
Due to the installation of the Lancer Evolution VIII rocker, the gears are now engaged symmetrically - the first is where the second is usually, and so on.

However, driving such a car every day is almost impossible - a huge expense, there is no radio, no air conditioning, no ABS... The only pleasant detail is electric windows, but I’m afraid that this is not enough to use such a toy every day, even for a person who is in love with his car.

Unrequited love

Are such tuning creations advisable? This is where the fun part begins—the cost of the project. This particular G8 has a construction budget of more than 1.2 million rubles. This is the price of speed, and this should not be surprising. For example, preparing the same Lada Granta for circuit racing costs a little less than two million. Moreover, you need to understand that serious tuning is a hobby for well-to-do people whose interests border on motorsport. And nothing else.

The bottom of the overcooked aluminum body is perfectly smooth, which facilitates the passage of air flow, which is also divided by the rear diffuser so that lift does not appear at high speed.
In addition, if you look closely, you can see the absence of a junction between the third door and the wing. The parts are welded together for even greater rigidity of the body. Access to the trunk is now provided by the opening rear window.

Tuning the VAZ 2108 engine

Those car enthusiasts who, in addition to visual appeal, also prefer power in a car, should think about modern engine tuning. There are some major improvements that can be made here. For example, use a different type of engine, that is, an injector. For this car, engine tuning with the installation of an injection system is a more profitable option. You can improve the turbocharger, compressor and other equally important components. If there is no opportunity or desire to change the type of engine, then auto tuning 2108 may include the installation of filters, expansion and cleaning of channels, as well as an increase in cylinder volume.

Those car owners who drive around the city more often need to pay attention to the torque. It is advisable to maintain it at a certain level at medium and low speeds. To do this, you need to replace the shaft in the engine system. After replacing the camshaft, it is advisable to “tune” the cylinders. As the shaft stroke increases, the filling of the cylinders with the fuel-air mixture will increase. This can provide increased torque. That is why replacing cylinders is a mandatory tuning. If you wish, you can change the pipe that removes exhaust gases. An excellent option is to use a special design consisting of 4 pipes. Everything is simple here. First, all pipes go into a two-pipe structure, and then into one. Thanks to this, it is possible to maintain the required torque value for the new (tuned) engine.

In addition to all of the above, you can modify the throttle valve. All you need to do is increase its diameter. In this case, the overall throughput of the damper will increase significantly. Also, in addition to engine tuning, improvements can be made to the transmission and braking system. If we talk about electrical equipment, there are also a lot of possibilities here. You can install additional lighting and headlights, a drive system for mirrors and heating. In addition, electric windows can be installed. A sophisticated alarm system would also come in handy. It is worth paying attention to purchasing reliable and practical windshield wipers, as well as windshield sprayers. An excellent investment is the purchase of imported alternator belts and spark plugs.
