How to install a turbine on a VAZ 2112

Almost all car enthusiasts today are trying to somehow make their car stand out from the crowd, to make the car special. Driving performance is improved almost immediately after purchase. You can often find a turbo VAZ on the roads. By installing turbocharging on AvtoVAZ engines, you can significantly increase engine power. But without a turbine, but with the installation of tuned components, it will not be possible to obtain a significant increase in power. Let's see how to assemble a turbocharged engine for a VAZ.

What you need to know about supercharging

Turbocharging is the forced injection of air into the combustion chambers by creating a high-pressure zone at the inlet of the intake tract. When the driver of the car presses the pedal and the throttle valve opens, significantly more air will enter the intake manifold than if it were supplied at atmospheric pressure. As the amount of oxygen increases, the carburetor or injector also increases the amount of fuel. Due to this, the engine power increases.

The combustion chamber has a fixed size, and its volume is a constant value. On a standard engine, only a limited amount of the fuel mixture fits into it. To increase power, it is necessary to place a larger volume of fuel in the cylinder. This is achieved by creating high pressure, which will compress the mixture. Then it will take up less space. This is why turbocharging is needed.

A little theory

Such improvements can be carried out more effectively by those who have a clear understanding of their own actions. To do this you need to understand the theoretical part.

So, the car’s power and fuel consumption depend on the properties and degree of enrichment of the fuel-air mixture entering the cylinders, as well as on its volume.

The fact is that an ordinary engine, when operating, pumps air into itself due to the vacuum created by the piston. In a turbocharged power unit, this work is done by a turbocharger. At the same time, the air is compressed earlier, which allows you to pump in a larger volume. In other words, you can burn a larger volume of fuel. The result is an increase in engine power in relation to engine volume and fuel consumed.

One fundamental point: air, as is clear, heats up under strong compression. Secondly, it will heat up during compression in the combustion chamber. With all this, detonation may occur. And, in addition, due to heating, the air density in the cylinder will decrease, which will naturally reduce the efficiency of the entire system. To remove these bad phenomena, intercoolers are used - air coolers from the turbine. They are a radiator.

As already mentioned, there are two types of compressors:

A turbocharger that operates by using the energy of exhaust gases. The processed gases enter the impeller and spin it, which is why air is pumped;
Mechanically driven compressor. It is powered by a motor drive. With all this, efficiency decreases and fuel consumption increases compared to the first version of the compressor, because the mechanical supercharger takes away part of the power from the internal combustion engine.

The entire system, not counting the turbine itself, contains several more fundamental components that need to be kept in mind during installation:

a control valve that maintains this pressure;
a bypass valve, which ensures that compressed air returns back to the compressor inlet pipes if the engine throttle valve is closed;
a bleed valve that releases compressed air into the atmosphere when the throttle valve is closed;
air pipes;
oil pipes (serve for lubrication and cooling of the turbine).

Hi all ! In this video I will talk about the design of a turbo engine in our implementation. Enjoy watching.

Where to begin?

Not every car is suitable for tuning. It is important to pay attention to the condition of the car. It is better to disassemble the car to the ground. The main problem is corrosion. You need to understand that the metal on AvtoVAZ cars is quite thin, and high loads are contraindicated for it. If you apply a serious load, the rusty metal will literally tear.

You should start by replacing the metal in the engine compartment with a more powerful one. When all body faults have been repaired, you can continue tuning further. If the car was purchased specifically for tuning, then the first thing you need to do is get it moving in stock condition. Next, they change the electrical wiring, bring the engine into good condition, or change it to a sixteen-valve one. The brake system and transmission are also inspected.

This is the first point from which the instructions for turbocharging begin. When the iron has returned to an ideal, close to factory condition, you can continue further. Moreover, we already know enough about turbocharging equipment.

Installing a turbo on a VAZ 2114: where to start

Installing a turbine on any car begins with a thorough examination of the hardware. You can’t just go to the store and buy a ready-made kit. And even if it is possible, the system will still have to be modified.

Turbocharged engine VAZ 2114

If you take on this task, consider the following:

A number of stock units of the VAZ 2114 are unsuitable for a car with a power of over 150 hp. It will not be possible to do without re-equipping the suspension and brakes, installing wider wheels with a turbo engine.
Tuning foreign cars is partly easier if the model being tuned has “bigger” brothers with turbo engines. Tuning usually comes down to searching, purchasing and adjusting ready-made factory units. It’s more difficult with Togliatti-made cars - VAZs don’t install turbines. Fortunately, in large cities there are tuning studios that develop and produce tuning parts. True, their products are mostly unlicensed, so there will be problems with legalizing changes.
The correct choice of turbine is the key to successful turbo tuning. Before realizing your dream, we recommend that you read brief descriptions of the turbines used to modify the VAZ.

Suitable engines

The easiest way is to make a VAZ turbo based on a 16-valve unit. It has a fairly simple design and is therefore also easy to tune and maintain. And most importantly, it is ideal for motorsports, as it can produce sufficient power at minimal cost.

Old engines equipped with a carburetor power system are practically not amenable to such tuning. But some craftsmen still build a turbo VAZ-2106. 8-valve injection engines would be suitable for civilian use, but in motorsport every horsepower is needed and important. Auto tuning experts recommend using 16-valve VAZ engines.

Turbocharger

This supercharger is made as a separate unit, which is driven by a drive belt.

The latter will take torque from the crankshaft. The compressor is in no way connected to the lubrication or cooling system of the engine. To relieve excess pressure, which sometimes occurs in the intake tract in some operating modes, an additional valve is connected to the air valves. Often, two types of compressors are used for tuning cars - centrifugal and screw. The first is made in the shape of a snail, inside of which there is an impeller. In a screw compressor, pressure is obtained through the simultaneous rotation of two shafts equipped with blades.

Centrifugal compressors are used for self-tuning of cars. They are more affordable, have small overall dimensions, and are easy to install. Due to the fact that the performance characteristics are limited by the engine speed, it can produce no more than 0.7 Bar of pressure. The compressor can increase engine power from 15% to 30% at maximum speeds of up to 40 thousand per minute. This is a pretty serious indicator.

Among the advantages of compressors are high durability and reliability, low requirements for the condition of the motor, ease of installation, and accessibility. During operation of the turbocharger, pickup occurs at speeds of three or more. The engine immediately responds to pedal pressure - in this case there is no so-called “turbo lag”, which happens when installing other superchargers. However, at high engine speeds (more than five thousand), the increase in power is almost unnoticeable.

TURBO KIT GARRET 1752

Turbo kit Garret 1752

Turbines from Garrett are consistently among the most popular among VAZ owners.

Among the reasons for this:

sold as a ready-made set, there is no need to assemble individual elements using spare parts at car dismantling yards;
relatively low cost (a new set will cost 30-35 thousand, used ones can be found in the range from 15 to 25 thousand);
without any special modifications, you can remove the boost from the car to 0.5 bar, increasing power to 120-130 hp. and torque up to 180-200 Nm;
with additional modifications to the boost system, the boost can be increased to 1 bar, power – up to 170-200 hp, and torque – up to 240 Nm.

The boost kit from Garret is optimal for novice fans of turbo tuning. By setting the boost to 0.5 bar, you can get a good increase in power without reducing engine life. For serious “rides,” this option is not suitable due to its limitations.

Gas turbine

Among the features of the turbine, one can highlight its rotation speed. It can reach 200 thousand rpm, and the pressure can reach up to 2 bar. This turbine can increase engine power by up to 50 percent. Turbine bearings rotate at enormous speeds and require lubrication. The system is connected to the lubrication system of the internal combustion engine. The turbine needs a certain time to gain the required speed. Therefore, it will start working only after three thousand revolutions. If you try to press the accelerator pedal sharply at low crankshaft speeds, the exhaust gas pressure will be too low for the unit to operate. You can feel the failures. This phenomenon is called nothing less than “turbo lag”.

8-valve engine kit

The turbo kit for the 8-valve engine has the following characteristics. It is capable of generating pressure up to 0.5 Bar. With this kit you can increase power to 120 horsepower and torque to 190 Nm. Installing this kit does not affect the life of the power unit in any way. Installation is quite simple, and all parts from the kit are hinged. There is no need to modify the engine in any way for installation.

The turbo kit includes:

Steel manifold.
Turbocharger.
Gaskets.
Oil supply hose.
Coolant supply system.
Valve for releasing excess pressure.
Connecting elements.
Fasteners and other parts.

Turbines for VAZ cars

There are many options for installing a turbine on the 2114 model. Theoretically, anything can be adapted, but the following models are best suited for an 8-valve engine:

Garret 1752;
Mitsubishi TD04 (installed on Mitsubishi Lancer EVO, Subaru Impreza WRX, and some other models);
IHI VF10 (this model was equipped with the 1st generation Subaru Legacy cars), as a variant of the VF11-20 (stock for the 2nd generation Legacy);

The list can be expanded with dozens of positions, including more powerful turbines TD05, TD06, VF23-30.

For the first boost we recommend Garret, TD04 or IHI VF10-20. They are widespread, inexpensive and repairable.

Moreover, if there is not enough money for new equipment, it is not difficult to find used kits in decent condition due to the transition of their owners to more powerful equipment

Installation

It must be remembered that equipping an engine with a turbocharging system is a rather lengthy process. Although kit manufacturers say that you can do without upgrading the engine, this is not entirely true. Where to begin? Of course, with the purchase of the necessary spare parts and preparation of the engine. It is necessary to replace the pistons, rings, cylinder head gasket, fuel regulator, throttle, as well as pipes and other parts. All these mechanisms must be as reliable as possible.

You also need to remember that building a powerful car can vary significantly depending on the turbine model. The instructions will be quite average. For example, in order to build a turbo VAZ-2106, you first need to replace the engine.

It is necessary to install a 16-valve injection unit. The first step is to prepare the engine. The engine is disassembled, the cylinders, crankshaft, connecting rods, and oil pump are checked. If necessary, grind the block. Pistons should be purchased after the cylinders have been prepared.

Next, the attachments are assembled. At this stage, the injectors are installed and the fuel pump is changed. Then a receiver and exhaust manifold are installed and a turbine is used. All steel elements are also installed. And finally, the last stage is setup. The maximum power, torque and other characteristics of the motor will depend on how professionally and correctly the adjustment is performed. If all the operations for preparing and assembling the system can be done with your own hands, then for setup it is better to turn to professionals (especially if the VAZ is a turbo on gas). By the way, there is now a lot of controversy about whether it is possible to install an LPG on a “turbo”. Experts say that the octane number of such a mixture is more than 102. Therefore, gas will not harm the operation of such a power unit.

One of the options to significantly add power and horsepower to the VAZ-2112 engine is to install a turbocharger. Such a modification can not only make your car stand out among the gray road mass, but also seriously “press” you into the car’s seat. However, in addition to installing turbines, experienced owners install a naturally aspirated engine or equip it with a compressor, and in this article we will figure out which is better and what modifications the entire car needs before installing such modifications.

Selecting the type of turbine

Before proceeding with the installation of the turbine itself, anyone who decides to do this should understand the global improvements that his car will undergo. And modifications always mean money and sometimes quite a bit, because it can affect the body, brakes, suspension, and in certain cases, the gearbox (choice of gearbox oil).

But before all this, you need to decide what type of turbine you want to mount on your car. After all, its power is a direct indicator of its cost. Conventionally, turbines are divided into three types:

Low pressure turbine – up to 0.5 bar . Installing such a turbine will require minor interventions in the operation of the engine, but it will also provide power.
High pressure turbine - from 0.6 bar . The installation of such a turbine may entail global changes in the gearbox, ranging from changing the oil in the gearbox, replacing the clutch with a sports clutch and other elements and engine systems.
Ultra-high pressure turbine - in this case, the pressure of the turbine itself is not so important as the applicability of the car itself as a whole. Since the use of such a car on public roads is absolutely excluded, since the racing components of such an engine are at least uncomfortable and inconvenient in general city traffic.

Equipping the VAZ-2112 with an ultra-high pressure turbine has no basis, and if installed, it will only be its junior analogues. Therefore, below we will look at what will have to be changed when installing low and high pressure turbines.

The theory of turbocharging

Of course, we need to start with the theoretical foundations of supercharging. It is divided into conventional mechanical supercharging and turbocharging (turbocharging). In both cases, the turbine creates the boost, and the differences lie in the drive with which the turbine operates. In the first version, the turbine rotates from the engine. This allows you to get rid of a delayed reaction or turbo lag, since the turbine speed directly depends on the engine speed, and hence the pressure created. Although at the same time we have an additional element, the operation of which takes away some of the power from the engine. Turbocharging is a more complex design, because it consists of two turbines at once. The purpose of the first turbine is to pump the air mixture into the engine cylinders, and the second is designed to rotate the first; it is installed immediately behind the exhaust manifold and is driven by exhaust gases. If we talk about the process itself, in this case it looks like this:

Exhaust gases, escaping through the cylinder valves into the exhaust manifold, drive the drive turbine;
This turbine transmits rotation through a common shaft to the discharge turbine;
The injection turbine, rotating, creates air flow and pressure in the intake manifold.

Turbocharging has a great advantage over mechanical charging in terms of efficiency, because the engine costs practically nothing for its operation, however, the “turbo lag” effect is already observed here. What does it mean? This is observed when the gas pedal is sharply pressed to the floor, because in this case there is no immediate reaction of the engine. What happens in this case? The engine needs time to spin up the turbine, and for this it is necessary to increase the speed to at least a level of 3 to 3.5 thousand rpm. All turbines are conventionally divided into 2 groups:

Low pressure turbines (0.2 to 0.6 bar);
High pressure turbines (up to 1 bar and above).

Installing high-pressure turbines requires more serious modifications to the engine and most vehicle systems, while low-pressure turbines allow the use of most standard parts and components.

Rework during turbine installation

Before proceeding with the installation of the turbine itself, some parts and elements of the engine may require modification:

Compression ratio

New elements are ready for installation.

The task of reducing the compression ratio may be to replace pistons or modify the cylinder head. Please note that when installing a low-pressure turbine, only the pistons can be modified, but for high pressure both are changed at the same time.

Exhaust system

“Spider” and “direct flow” can be installed.

The best way to solve the exhaust system is to replace the manifold and “pants” with the installation of a “spider”. Remember that such systems should only be purchased from trusted sellers, whose products are made of high-quality materials that can withstand the maximum temperatures from turbine operation.

With low-pressure turbines, after the exhaust pipe of the “pants”, everything can be left unchanged.
With a high-pressure turbine, the transition to “direct flow” is very noticeable, since the full potential of this type of turbine can be very well revealed.

Injection system

The new injector is different from the old ones.

If the pressure of the turbines is low, it is possible to replace the receiver; fortunately, their choice in modern tuning stores is very wide, but for the older brother, the fuel pump and injectors will need to be replaced with the most efficient ones.

Electronic control unit

You should read about its installation separately.

You should also read the manual about careful installation of this device.

When installing any type of turbine, mandatory firmware of the “brains” will be required. And on a turbine with a total power above 200 hp, it will also be necessary to replace the mass air flow sensor with a DBP (absolute pressure sensor - approx.) and an air temperature sensor (air temperature sensor - approx.). And this is done because the standard sensor is simply not designed for the passage of such an amount of air. Until they are installed, it will not be possible to reflash the ECU correctly.

Lubrication

Any turbine needs lubrication and for this it is necessary to provide it with an oil supply. This is done in various ways, either by installing a special tee in place of fixing the oil pressure sensor and then connecting a special hose to it, or by using an adapter with an outlet for the oil filter. In any case, no matter which method you choose, the oil must be drained only into the pan through a metal tube.

Cooling system

The intercooler is a small radiator instead of a bumper.

To ensure the best cooling of the engine, an antifreeze supply will be required from the general cooling system. And in order to cool the air supplied by the turbine, an intercooler must be installed. When installing low-pressure turbines, many people mistakenly think that installing such a device is not necessary, but in the summer, the standard system simply cannot cope with its responsibilities.

The engine itself will also need cooling, and in the case of the VAZ-2112, installing a double-row copper radiator is ideal. This is quite enough for its optimal cooling.

Bypass valve

The valve in the photo is Blowoff.

The bypass valve is necessary to relieve excess pressure that may arise in the system when the throttle is suddenly closed. And so that it does not break out through the rubber elements and connections and cause them to rupture, such pressure is released into the air. There are two types of valves: Blowoff is a valve that must be installed next to the throttle valve, and Bypass is mounted between the intercooler and the air line.

Wastegate valve

The price of such a device is quite high.

The purpose of such a valve is to allow part of the exhaust gas to bypass the turbine, thereby limiting its speed and reducing its excess pressure at the inlet. They come in two types:

External ones - are installed more often on racing cars, as they have very significant dimensions, and internal ones , which are installed directly on civilian types of wastegate turbines.

High pressure turbine block

If your goal is to achieve a total power of the VAZ-2112 of more than 200 horsepower , then we will not be talking about installing a turbine to the engine, but about assembling a new engine.
In this case, instead of a stock block, it is better to install one from a Lada Kalina, since with it and with a correctly selected crankshaft you can achieve an increased volume. Pistons, connecting rods, etc. can also be replaced.
There are many options for such a design, and it all depends on how much you are willing to invest in such a modification.

Other changes

Depending on what budget and imagination you have, you can modify the engine in either direction. For example, it may be necessary to install different spark plugs, or a fuel pressure regulator, modified injectors or a fuel pump.
To install some types of turbines, a change in the design of the front bumper may be required, since there is simply not enough space to install an additional radiator.

Turbo KIT

Turbo KIT assembled.

In order not to bother with installing a certain type of turbines and equipment for them, it is possible to purchase a special Turbo KIT kit. As a rule, such a kit includes the turbine itself and everything necessary for its installation.

Nowadays, in tuning stores you can see a large selection of similar, varied kits, in which everything is done to make installation as simple as possible.

Turbine prices

It is possible to install a turbine at a service center with about 100-150 thousand rudders in your pocket . This price includes the price of the turbine and components, as well as all work on its installation.

However, it must be remembered that the installation of each model is strictly individual and requires personal calculation.

Pros and cons of turbine, compressor and naturally aspirated engine

Let's consider all these methods of engine tuning separately.

Turbine

Under the hood of a turbocharged VAZ-2112

In recent years, the installation of turbines on cars of the VAZ family has become quite widespread. And there is nothing unexpected about this, since they are the most common, unlike mechanical inflation (compressor - approx.), because they have a number of advantages.

Firstly, the supercharger is located next to the turbine impeller and is built into the exhaust manifold, driving itself with exhaust gases. Secondly, such an arrangement of components can significantly increase the efficiency of the entire engine, because there is no direct connection between the turbine and the crankshaft, since it does not take power from the engine itself. Experienced auto mechanics call this the main advantage of a turbine over a compressor.

If such designations are difficult for you, in one word, a turbine pumps a lot of pressure into the cylinders and the higher it is, the greater the power.

Turbine disadvantages

However, the turbine has its drawbacks, and these include “turbo lag”. This effect manifests itself in a slow response to pressing the gas pedal, and at low speeds the turbine operation will not be felt at all. The explanation for this is very simple: in order for the engine to begin to gain power and speed, it requires time for the exhaust gas pressure to increase, which would be able to properly spin the turbine. For exactly the same reason, a turbocharged engine is capable of producing maximum power only after 4000 rpm.

Compressor

The compressor engine starts air movement due to a special mechanical supercharger operating using a belt drive. That is, the operation and power of the engine directly depends on the number of revolutions gained and the higher they are, the higher the power. In the design of the compressor, the air mixture with fuel is not only supplied to the cylinders under pressure, but is also capable of blowing through the exhaust and intake valves when they are not completely closed, thereby cleaning them. Because of this design, the engine is always able to operate at full power.

Disadvantages of the compressor

A significant disadvantage of such a modification is the unreliability of the drive belts, which will one way or another break and become unusable, as well as increased fuel consumption, since the compressor is best installed on engines with a large volume, since the efficiency of interaction with them will be much higher.

Atmospheric engine

When talking about an atmospheric engine, many people think of anything but what actually exists.

An atmospheric engine is a regular engine that does not have any supercharging, that is, turbocharged or compressor. However, there are some nuances here too.

The atmospheric engine is both simple and the most complex in its design. Since the ideal fuel-air mixture is supplied to the cylinders of this engine, without any obstacles or resistance in its path. The manifold works perfectly on this engine, the camshaft is adjusted as precisely as possible, the cylinder diameter, piston stroke, and so on are increased. And all this is done to increase the rated power of the engine.

Despite the fact that this is a seemingly ideally built engine, the advantages of which include the strictly accurate response of the gas pedal and a good reserve of power at any speed, it also has disadvantages in comparison with its turbocharged counterpart.

Cons of a naturally aspirated engine

The first disadvantage due to which you can give preference to the “turbo” is the very high fuel consumption and the high degree of wear of the internal parts of the engine. It is also impossible for a naturally aspirated engine to more than double the stock power, whereas a turbocharged engine can increase it several times.
Heavily promoted “aspirated” engines only drive at high speeds, which has a negative effect when driving in urban conditions. They also have a high idle threshold, which is also inconvenient for everyday use.

As you can see, all three types of engines have their advantages and disadvantages, but today we will focus on the turbine , since this is the most suitable type of tuning for the VAZ-2112 engine.

Turbines based on IHI VF10 compressor

Turbocharger VF22

Subaru has experimented with turbo engine configurations more than other manufacturers. On the same WRXs you can find Garretts, and the famous Apexi, and Mitsubishi. Not the last place in this series is occupied by the American manufacturer IHI, whose superchargers were installed on legendary cars like the Chevrolet Camaro.

VAZ is equipped with many variants of turbines from IHI, including:

VF22
VF23
VF24

These are classic drag racing turbos that boost extremely quickly, already at 2800-2900 rpm.

The VF10 is less powerful than either of these options. Peak power is about 250 horses (rarely, with very professional tuning and a strong reduction in resource - up to 300). By comparison, the 20th and 30th numbers are capable of developing up to 325 or more horses. But for the VAZ engine, the “ten” (as well as the VF11-20 turbines similar to it), according to many turbo experts, is optimal.

When compared with the TD04 and even the TD05, the VF10 will be faster at the bottom, but the turbo lag will be more noticeable. A VAZ 2114 with such a turbine will feel better on drag or in circuit racing with a minimum of long straights.

conclusions

Installing a turbine on VAZ-2112 engines is a very complex and responsible task. Of course, errors in its execution can lead to breakdown of both the turbine itself and the engine as a whole. Therefore, this issue should be approached with appropriate means and a responsible approach to the matter. Installation of turbines should be carried out in specialized workshops staffed by highly qualified specialists.

We advise you to study the technical characteristics of a particular turbine, and possibly a KIT turbo kit, from the very beginning.

...very, very frequent questions that I received in a personal message: “how much did your turbo cost?”, “what do you need to collect?”, “why are you so impudent?” (joke) etc. I have never tried to calculate, because it is really difficult, especially considering that in my case something is constantly changing/refining/improving.

However, I want to tell you and try to derive some numbers about the turbocharged stage that preceded the current configuration, and which is very popular among VAZ turbochargers in general in the vastness of our homeland. I’ll try to come up with the optimal recipe and collect all the necessary information in one post with instructions for action.

So, a turbo kit based on minor engine modifications, on a TD04 turbine (and its monoscroll modifications), pressure 1-1.4 bar, estimated power 190-230 hp. Approximate budget $2500-3500 (spare parts + labor + setup)
