Installation of the 16-valve engine on the "classic": advantages and disadvantages

Why is it necessary to install a 16-valve engine on a "classic"? And is the game worth the candle? A unequivocal answer can be given only if we analyze all the advantages and disadvantages of such an alteration. First you need to consider what the engines of the classic series and more modern ones are, for example, installed on the VAZ-2112. While carrying out the work, there may be some difficulties, but they can be overcome if you approach the matter with a bright head.

For most people, tuning is the attachment of plastic body kit and stickers to the car body. There was even such a thing as "collective farm tuning". This phrase describes cars that are difficult to move on the road, but are hung from the roof to the wheels with stickers with the emblems of any brands. Much nicer, when a simple car that does not stand out from the crowd, has technical characteristics comparable to vehicles of foreign production, and not the lowest class.

And why is it necessary to install a 16-valve engine for "classics"?

Cars of the classic series have not been produced for many years, but spare parts for them are still on sale. Pay attention to the engine - only eight valves, in the "harness" of just over seventy "horses", and the timing chain produces terrible sounds, increasing the noise level. Increase the power and acceleration of the car in several ways:

1. The change in the fuel system (the transition from morally obsolete carburettor to injector).
2. Replacing the engine with a more perfect model.
3. In the case of injector cars, the change in the firmware of the computer can help (fuel consumption increases in proportion to power).

In more detail it is worth considering the second option. If you have a car with a carburetor engine, then you kill two birds with one stone - you install a new engine and change the fuel system completely. It is worth mentioning that the ignition system is also being transformed - instead of the contactless it will be necessary to mount a microprocessor. And hence the increase and reliability, and power, and longevity of the power unit.

Is such a substitute legal?

Recently, a law has been in place, according to which the motor of the car does not need to be registered. In fact, the engine for the "classic" becomes an ordinary spare part, like a bumper or a thermostat. But you need to adhere to the recommendations that come from specialists. When buying an engine, conclude a sales contract. If there is an opportunity, then poke in the base of the traffic police car, from which the power unit is removed. The seller must provide you with documents that confirm his absolute right to own a car or motor.

Subject to the purity of the transaction, you will not have any complaints. The next step can be followed after the installation of the 16-valve engine for the "classic". This is registration in the State Traffic Safety Inspectorate. Attitude to the procedure for many is twofold, as some try to formalize the alteration so that everything is official, while others use the fact that no inspector has the right to inspect the engine, and can not even open the hood. Even at the official inspection of such alterations, special attention is not paid.

What advantages and disadvantages are expected from installing a new motor?

Most importantly, you will increase the power and throttle response of your car. The installation of the engine of the 2112 in the "classic" gives one more advantage - quiet work. Due to the fact that the rubber belt is used instead of the timing chain, the noise level is reduced. Speed also increases. The reliability of many units in modern engines is much higher. In terms of ecology, you reduce the amount of carbon dioxide released into the environment. This is realized by the introduction of a catalyst, whose operation is controlled by two lambda probes.

The disadvantages include the need to rework almost all the systems of the car:

1. Brake.
2. Electrical equipment.
3. Fuel.
4. Ignition.
5. Coupling.

If you are offered a motor without attachments, it is better to refuse it, since it will be costly to buy everything separately. The new 16-valve engine, the price of which is within the range of 60-80 thousand rubles, is too expensive for most. Therefore, it is better to use the services of the secondary market, where the cost of the motor varies from 20 to 30 thousand rubles. And usually they sell not only the engine, but also all attachments, including the computer and fuel system elements.

Why do you need to remodel your car systems?

It is worth remembering that the installation of the engine of the 2112 in the "classics" entails many changes. And not only in the design, but also in technical characteristics. Increase speed and power, torque. And the standard braking system is designed to work with an old motor. And it can not cope with the loads that will appear after the design changes the car. Fastening the engine takes a little time - just screw it with three bolts to the gearbox. But its proper connection, tuning, adaptation of systems to new characteristics is a whole science.

Without a certain knowledge of the design of the car and its components, one should not even attempt alterations. Brakes on the "classic" should be replaced, even ventilated discs can be used for more efficient operation. It is also better to use disc brakes on the rear wheels. On the drum, the effectiveness of which is not always good, it is better to completely forget. The clutch unit operates under heavy loads, rather than earlier, therefore it is recommended to use reinforced models. And do not forget about the crossings installed on the cardan. It is desirable to replace them with more reliable, quality metal.

Summarizing

You will get many benefits from upgrading your car. Try to perform all the work competently, not only from the technical, but also from the legal side. Remember that it is impossible to sell a car with a motor that is not registered in the traffic police without hindrance. And installing a 16-valve engine to a "classic" is not an easy task, as it will not only be necessary to carry out work to change all associated units, but also to lay the wiring harnesses.

Modern engines work thanks to microprocessor systems and control devices (sensors), which are many in the car. Incorrect connection of only one element will result in the motor not starting or running with interruptions. For this reason, the installation of the engine 2112 in the "classic" is complicated, because the standard wiring does not have harnesses for new equipment.
