Tuning the VAZ 2109 engine on your own

When it comes to improving the technical characteristics of any domestic car, the first thought that comes to mind is the phrase: “We need to put in a different engine, from a foreign car, for example.” But not everyone can afford this option, so today we will talk about how to make a VAZ 2109 engine tuning on our own.

You need to start tuning the engine with a check and, if necessary, with the modernization of the brakes and gearbox. When all work in this direction is completed, you can safely proceed to setting up the motor itself.

Two options for tuning the VAZ 2109 engine

The first, and the simplest and most inexpensive option for tuning a VAZ 2109 carburetor engine, is the usual reworking of engine components that any craftsman can grind, polish, bore. Already this may be enough to slightly improve the performance of the car. But, if you want to get closer to the ideal, then you should turn to the second option - a serious processing of the "heart" of the machine.

When tuning the VAZ 2109 engine, pay close attention to the camshaft, phase adjustment and lift height. Replacing these parts allows you to add power to the car.

You can use any of the methods that provide for the installation of a lightweight crankshaft with a piston stroke of 78 mm, lightweight connecting rods with a size of 121 mm, lightweight piston rings, forged pistons with a diameter of 82.5 mm, a cylinder head taken from a LADA Kalina car and a camshaft measuring 11.3 mm. Taken together, this will allow you to get an engine power of 98 horsepower and the ability to reach speeds of up to 183 kilometers per hour.

Alternatively, you can use titanium springs on a piston with a connecting rod. This will allow to obtain a rational distribution of energy during fuel combustion. On the one hand, this allows you to save fuel, and on the other hand, it increases the power of the car.

In short, when tuning the VAZ 2109 engine, the carburetor can also be replaced. But in general, when tuning a carburetor engine, remember that in order to improve the quality of its work, weakening the friction force in the cylinder-piston-ring chain, reducing the mass of connecting rods, pistons and fingers, reducing the thickness of piston rings, reducing their number.

Tuning engine VAZ 2109: injector. Note that on an electrified car does not require any mechanical intervention. To change the technical characteristics of the mechanism, you only need to change the settings of the electronic control unit of the entire engine.

Sports tuning of the VAZ 2109 engine

If you sleep and see yourself as a winner in sports competitions, then you should start boosting the engine of the car for sports purposes. To do this, you need a lighter crankshaft, lighter connecting rods, lighter pistons, a new gearbox, oil jets, a new clutch and a lighter flywheel. Plus, you will need to install a contactless ignition system, a sports muffler and a copper radiator.

Life after tuning the VAZ 2109 engine

I would like to remind you that if the details of the "nine" are at least somewhat different from the standard factory elements, then even a minor breakdown on the track will lead to the fact that you will need to call a tow truck or use a cable, again, causing help from someone you know.

Yes, it will become more difficult to repair a modified car engine, which can make the repair cost prohibitive. To reduce it, it remains only to carry out repairs yourself. Yes, this is a serious matter, and there are pitfalls.

Another point to pay attention to is fuel consumption. For example, if you install a camshaft with an increased phase, then the engine will respond to this with a large fuel consumption. Naturally, this can be compensated by replacing other elements, gradually bringing the car closer to what you consider ideal.
