Why is it necessary to install a 16-valve engine on the "classic"? And is the game worth the candle? A definite answer can be given only if you analyze all the advantages and disadvantages of such a rework. First you need to consider what are the engines of the classic series and more modern, for example, installed on the VAZ-2112. When carrying out work, some difficulties may arise, but they can be overcome if you approach the matter with a bright head.
For most people, tuning is the fastening of plastic body kits and stickers on the car body. There was even such a thing as “collective farm tuning”. This phrase describes cars that hardly move on the roads, but are hung from the roof to the wheels with stickers with emblems of any brands. It is much nicer when a simple car that does not stand out from the crowd has technical characteristics comparable to foreign-made vehicles, and not of the lower class.
And why do we need to install a 16-valve engine on the "classic"?
Cars of the classic series have not been manufactured for many years, but spare parts for them are still on sale. Pay attention to the engine - there are only eight valves, there are a little more than seventy “horses” in the “harness”, and the timing chain makes terrible sounds, increasing the noise level. There are several ways to increase the power and throttle response of a car:
- A change in the fuel system (transition from a morally obsolete carburetor to an injector).
- Replacing the engine with a more advanced model.
- In the case of injection cars, changing the ECU firmware can help (fuel consumption increases in proportion to power).
It is worth considering the second option in more detail. If you have a car with a carburetor engine, then you kill two birds with one stone - install a new engine and change the fuel system completely. It is worth mentioning that the ignition system is also transforming - instead of contactless, it will be necessary to mount a microprocessor. And hence the increase in reliability, power and durability of the power unit.
Is such a replacement legal?
Recently, a law has been in force under which a car’s motor does not need to be registered. In fact, the classic engine becomes a common spare part, like a bumper or thermostat. But you need to adhere to the recommendations that come from experts. When buying a motor, enter into a contract of sale. If possible, then punch the car from which the power unit was removed from the traffic police base. The seller must provide you with documents that confirm his absolute right to own a machine or motor.
Provided that the transaction is clean, you will not have any complaints. You can proceed to the next step after the installation of the 16-valve engine to the "classic". This is a registration in the traffic police. Many have a twofold attitude towards the procedure, since some try to complete the alteration so that everything is official, while others take advantage of the fact that not a single inspector has the right to inspect the engine, nor can he even demand to open the hood. Even at a state inspection, they do not pay much attention to such alterations.
What advantages and disadvantages are expected from installing a new motor?
Most importantly, you will increase the power and throttle response of your car. Installing the 2112 engine in the "classic" gives another advantage - quiet operation. Due to the fact that instead of the timing chain a rubber belt is used, the noise level is reduced. Also increases speed. The reliability of many units in modern engines is much higher. From an environmental point of view, you will reduce the amount of carbon dioxide emitted into the environment. This is realized by introducing a catalyst, the operation of which is controlled by two lambda probes.
The disadvantages include the need to alter almost all vehicle systems:
- Brake.
- Electrical equipment.
- Fuel
- Ignition.
- Clutch.
If you are offered a motor without attachments, then it is better to refuse it, since it will be unprofitable to buy everything separately. The new 16-valve engine, whose price is in the range of 60-80 thousand rubles, can not afford the majority. Therefore, it is better to use the services of the secondary market, in which the cost of the motor ranges from 20 to 30 thousand rubles. Moreover, they usually sell not only the engine, but also all attachments, including the computer and fuel system elements.
Why do I need to redo the car system?
It is worth remembering that installing the 2112 engine in the "classic" entails many changes. And not only in design, but also in technical specifications. Increase speed and power, torque. And the standard brake system is designed to work with the old motor. And she may not be able to cope with the loads that will appear after a change in the design of the car. Mounting the engine takes little time - just screw it with three bolts to the gearbox. But its proper connection, configuration, adaptation of systems to new characteristics is a whole science.
Without certain knowledge of the design of the car and its components, one should not even attempt to remake. The brakes on the "classic" should be replaced, even ventilated discs can be used for more efficient operation. On rear wheels, it is better to use disc brakes too. About drum, the effectiveness of which is not always good, it is better to completely forget. The clutch unit operates under greater loads than before, so it is recommended to use reinforced models. And do not forget about the crosses mounted on the cardan. It is desirable to replace them with more reliable ones made of high-quality metal.
Summarizing
You will get many benefits from upgrading your car. Try to do all the work competently, not only from the technical, but also from the legal side. Remember that it becomes impossible to sell a car without a motor with a motor not registered in the traffic police. And installing a 16-valve engine in the “classic” is not an easy task, since it will not only be necessary to carry out work to change all associated units, but also to lay the harnesses of electrical wiring.
Modern engines work thanks to microprocessor systems and control devices (sensors), which are many in the car. Incorrect connection of only one element will lead to the fact that the motor will not start or will work intermittently. For this reason, the installation of the 2112 engine in the "classic" is complicated, because the standard wiring does not have harnesses for new equipment.
