Car tuning should not end with the transformation of just the appearance. Particular attention should be paid to the power unit. The easiest option is to install a 16-valve cylinder head. But you can also install an engine from a foreign car or a newer Lada model.
VAZ-2109 was once a very popular car. Durable engine, sturdy body, attractive appearance. And the car itself was created with the participation of designers from the famous Porsche car company. But today, when the power is not enough, you involuntarily think about tuning the engine. But why do you need to increase the power? What to consider when replacing an engine?
For some time now, a law has been in effect in Russia, according to which an engine number is not required when registering a car. The motor is now considered just a spare part that can be replaced, like an air filter or a broken tire. It was this law that pushed tuning enthusiasts to improve their cars.
Considerations when replacing an engine
The ideal variant for "nines" is, of course, a similar engine. But in the case when a complete modernization of the machine is carried out, its capacity will not be enough. The most suitable option would be the 16-valve VAZ-2112 engine, which has more horses and a newer design.
And you can safely install an air conditioning compressor on such a motor, and it will be fresh and cool in your car even in the terrible heat. It is also possible to install an air conditioner on a standard "nine" engine, even with a volume of 1.5 liters, only there will be a noticeable shortage of horses. In addition, the generator will still have to be replaced, as the power of consumers increases.
The good thing is that the VAZ-2112 engine fits perfectly with the box of nine. Also, a good tuning option turns out to be the installation of an engine from the Priora, a more modern Lada model. As for foreign engines, the Hyundai Accent engine is perfectly installed under the hood of the nine, it is only advisable to take the gearbox from the "Accent". With the "Opel Vectra" also the power unit is suitable for tuning.
What else needs to be changed and done
You increase the power of the motor. Therefore, it is necessary to use more durable discs and pads in the brake system. The ideal option would also be to replace the rear drum brakes with disc brakes. There should be changes in the cooling system as well. Install a radiator that is designed for the new engine. It is quite possible that the volume of the VAZ-2109 cooling radiator will not be enough.
Be that as it may, but you must have the documents for the engine. If you buy it from your hands, then ask the seller for a document confirming the ownership. You should not buy a motor of unknown origin, as it can be removed from a car that is listed in theft. If you purchase a contract engine, the seller will provide you with both a guarantee and a full package of documents. But the registration of the alteration in the traffic police - it depends solely on your desire. The ideal option is to contact the traffic police with a request to design a new engine.
