Which of the car owners did not dream of increasing the power of their car? Everyone thought about it. Some would like to add 10 horsepower, others - 20. But there are those motorists who want to increase the capabilities of the car as much as possible. Their goal is the maximum increase in torque with a minimum budget, which means that a powerful engine from another car can no longer be installed. This means that there are only two options for increasing technical characteristics - a compressor or installing a turbine. The first one does not immediately fit - with it there will be a large fuel consumption, and the efficiency is low. And not all cars have a place to install such a unit. As a result, only the turbine remains. But the question arises: “Is it possible to put it on a naturally aspirated engine that is not intended for this?”. Let's consider this issue in more detail.

On the firstAt a glance, it may seem that installing a turbine on naturally aspirated engines is simple. It is enough to fasten the turbine, assemble the intercooler and immediately you can put pressure on the gas "for all the money." But is it really that simple?

Turbo features

The most important thing to understand is that while turbocharged engines are similar to atmospheric internal combustion engines, they are built on the basis of completely different principles. This is due to the specific features of the combustion of a mixture of fuel and air under conditions of excessive pressures and loads. The more air, the more fuel you need. Accordingly, the dynamics of the car will be more acceptable.

In practice, on the one hand, the planned increase in capacity is 20-30 percent, while the amount of work and the injection of funds are significant. Therefore, it turns out that it is most correct to raise the result to an average level so that the costs pay off and meet the desired requirements.

Is the game worth the candle

Many people believe that installing a turbine is a matter of two hours. But as a result, productivity will increase, and with it the load on the engine - you cannot do without replacing the main elements.

Reviews say that you will have to change nozzles. With a turbine, more productive ones are installed. They also change the fuel pump, install a new exhaust system - with pipes of a larger diameter. Next, change the lambda probe. Additionally, you need to find a suitable place for mounting the intercooler. They also change the piston system, improve the cooling system. In addition to all this, it is necessary to ensure the flow of oil to the turbine,reduce the compression ratio of the internal combustion engine, change the camshafts, install reinforced engine mounts.

The more extreme the tuning is, the more expensive and difficult it will be. An unpleasant surprise is the individualization of almost all equipment. Everything is done only for one car, in a single copy. This means that the price of installing a turbine will be at least fabulous (from 100 thousand rubles, if it is a VAZ). In the end, it will become clear that the engine was not suitable for all these alterations, and in fact the sum for everything will be the market price of one or two used turbocharged units.

But that's not all. When the engine is assembled, the next unpleasant moment appears - it turns out that the unit will not even start on a standard ECU. Such motors work with expensive reconfigurable control units. Need to change the firmware - say the reviews.

What is a turbine and how does it work

The principle of operation of the turbocharging system is based on the flow of exhaust gases from the exhaust manifold. They enter the turbine housing and spin the impeller, which is closely connected to the compressor wheel. The latter, in turn, sucks in an additional amount of air through the filter. Oxygen is used to enrich the mixture and then supply it to the cylinders. More mixture enters the chamber. This contributes to the growth of power characteristics and an increase in potential.

How to install boost

Before installing the turbine, it is important to remember that sealants cannot be used during the installation process. When exposed to high temperaturesthey liquefy, and their particles can get inside the turbine. A small piece is enough to completely destroy the device.

Installation begins with the replacement of filters - air and oil, as well as flushing the lubrication system. The oil lines are completely cleaned and the pipes are replaced with new ones.

Next, the breather is dismantled and cleaned. The turbine rotor is scrolled to determine the force of its rotation. And then the supply lines are thoroughly washed and then the oil is removed. Before installation, all turbine friction parts are thoroughly lubricated. Ordinary engine oil can be used.

Turbine rules and guidelines

Before you start installing the turbine on the Niva, you need to know a few recommendations. The engine must be gasoline, and it should be filled only with high-octane fuel. The turbine will create a pressure of up to two atmospheres - due to this, the compression ratio will increase significantly. Sports turbines will entail huge fuel consumption. Reviews say that a 1.6-liter engine will consume from 20 liters per hundred. In civilian operation, such tuning is not needed.

Proper fitting of a turbocharger to a carbureted engine will result in increased thrust, increased dynamics and improved acceleration performance. In everyday use, even high fuel consumption can be reduced – the time required for acceleration is significantly reduced. The climbing process will now be carried out in a different way.

Preparatory work

The installation operation requires certain preparations. Every little detail needs to be thought through. Technically, the installation is simple, but beginners may have some difficulties. The first step is to choose a turbocharger. It must be suitable for a specific engine. The scheme of work performed depends on the type of supercharger, turbine dimensions, as well as characteristics. It is necessary to find a compromise unit, where the combination of power and heat dissipation is as optimal as possible.

If a catalytic converter is installed, check if it works or not. Excess exhaust gases will interfere with the operation of the turbocharger. Also check the air filter. It must be tight and solid. And it's best to install a zero - say the reviews of the owners. The next step is to flush the crankcase ventilation system.

Also make sure that there is no sand or dirt in the air supply duct.

Turbine components

With proper installation on a mass-produced car, you can increase engine power by 1.5 times. The main component of the turbine is the exhaust manifold with flanges that fit into the seat. To exit the exhaust gases, you need a special flange with a nut for the lambda probe.

To seal the gaps, special gaskets are used. For the organization of the air duct, it is recommended to use aluminum pipes, silicone pipes and power clamps.

Installation work

Scheme for installing a turbine on an engineincludes several stages. First of all, the turbine shaft is set in motion and the speed of its rotation is memorized. Before installation, oil is poured into the unit and the rotor is rotated. At first, it is not recommended to twist the oil line - make sure that nothing obstructs the supply.

If everything is in order, then put on the air supply pipe and tighten the oil pipe. The engine is started for one and a half minutes. At this point, they monitor how the turbine works in different modes. If extraneous sounds (noise or whistling) are heard during operation, you should carefully and carefully check the correct installation. Air leakage "from the outside" must be eliminated.

Conclusion

Removing and installing the turbine is easy. Difficulties arise in the correct calculation and selection of components. As for the reviews of those who use turbocharging, in general this is a very effective tuning. However, it is hardly suitable for everyday use.
