Some drivers are interested in what engine can be put on the VAZ 2109 and 21099. Usually, this thought is visited by motorists who are looking for ways to tune their car. The thing is that the motors that are installed on these models were developed back in the 70s of the last century, and now they are somewhat outdated. In this regard, they are practically ineffective in comparison with more modern cars. For many connoisseurs of these models, the most effective way is to install a motor from a foreign car, since there are engines that can be installed on this car with a minimum number of alterations.

What should you pay attention to?

What engine can be put on the VAZ 2109 and 21099? Before answering this question, you should understand the legal and some technical features of this work. Recently, the motor has been considered an ordinary part, so no special documents are required to replace it. But, when buying a car with a changed engine, it is better to ask the previous owner for documents, otherwise there is a risk that the unit was removed from a stolen car. In this case, you may have a number of problems. Although, there are not so many cases of checking engines (for example, when a place in the TCP runs out), so you can ignore this factor at your own peril and risk.

On the other hand, you can, pleasant in this will not be enough.

A more difficult issue is the need to select an engine suitable for 2109. First of all, you should look at the size of the motor. The engine compartment here is not too large, so this is one of the main conditions for the selection of the unit. Also pay attention to the possibility of installing the engine. It is advisable to select options with a transverse arrangement, this will minimize the work of fitting the part.

Features of refinement

The biggest inconvenience when replacing an engine with a more advanced one is the need to adjust the electrics. In particular, the problem arises with more advanced engines from foreign cars, primarily due to the presence of a large number of sensors and a more accurate engine control system. Therefore, you will probably need the help of a person who understands an electrician.

When installing a more powerful engine, you should modify braking system. This will avoid problems. Also, the safety of movement by car will be significantly increased. Do not forget about the radiator, it must match the power of the new unit, otherwise you will receive it regularly, which will significantly reduce its resource.

What engines can be supplied?

In fact, the number of motors suitable for the "nine" is quite large, this allows you to make a choice with minimal time. Let's look at the most popular options among our motorists:

• Often, drivers are limited to installing a 16 valve engine that can use gas as fuel. This allows you to significantly reduce the cost of refueling the car. Please note that the installation of such an engine, as well as HBO, is possible only at specialized stations, otherwise you can get a serious fine;
• If you have a simple carburetor engine installed, then you can simply put a more advanced injection version. So you will avoid problems when installing the engine, the only thing that needs to be done is to install the control unit and correctly connect the sensors to it. Many drivers make a replacement along with the gearbox;
• From Priora or 2112. In fact, these cars have the same engine, but slightly modified. Thus, installation difficulties should not arise. These motors are more economical, which quickly pays for installation costs. At the same time, the cost of such a replacement will be minimal;
• Honda Civic 1.5 liters sample 91-95 years. These engines fit perfectly under the hood of the "nine". At the same time, there are practically no difficulties with fitting the mounts. As a result, you will get a better power unit;
• Mitsubishi Lancer. You can use a motor with a volume of 1.5 liters and a power of 100 hp. This power unit has excellent dynamics. For installation, you will have to slightly change the motor fasteners, as well as pay attention to the brake system;
• Production motors Opel. Here you can take almost any engine installed on the Vectra. These power units, of course, are quite old, but at the same time, they are more powerful and more reliable than the VAZ originals. The build quality here is at a fairly high level. At the same time, the cost is relatively low, which often turns out to be one of the main factors when choosing;
• Volkswagen Golf or Passat, the motors of these machines, released in the 90s, are perfect for your "nine". Alterations will have to be made, but they are minimal. As a result, you will get an engine with real German quality;
• Hyundai Accent Yes, you can install a power unit from this Korean car. Please note that it is quite powerful. You will also have to put a box from him, since the native will not cope with the increased load;
• Engines fiat. These units are perfectly combined with AvtoVAZ products. For installation, it is better to use options with a volume of up to 2 liters. It is better to use versions with 16 valves. Unfortunately, modern motors are not suitable for installation on the "nine", so you have to look for suitable options for disassembly;
• Audi A80 and A4. These German motors can also, if desired, be installed on 2109. The engines are of sufficient quality, but for greater reliability it is recommended to use parts with low mileage. So you are guaranteed to avoid problems;
• Mazda 626. Great motor, powerful enough. It perfectly withstands refueling with low quality fuel. This power unit is highly reliable. This will minimize the need for repairs during operation. A small disadvantage is the relatively high cost.

Conclusion. Domestic cars have never been able to boast of high reliability, as well as excellent technical performance. Therefore, many drivers are interested in which engine can be installed on the VAZ 2109 and 21099. Installing a power unit from a foreign car or a more modern domestic car is the most effective tuning method. When choosing a model, pay attention to the dimensions, as well as the possibility of fitting engine mounts.

Installing the engine on the VAZ 2109

The installation of the VAZ 2109 engine is carried out in the reverse order of its removal. When connecting the front wheel drives to the gearbox, replace the circlips on the splined shank of the inner joints. Do not install used circlips on the splined shanks of the pivots as this may cause the front wheel drives to disengage from the transmission while driving. After installing the engine on the car, adjust the carburetor air and throttle actuators, the clutch actuator, as well as the angles of the front wheels.

Fill in the coolant of the cooling system, engine oil and gearbox oil.

Start the engine and check for fuel, oil and coolant leaks. Check oil pressure. Listen to the engine, it should run smoothly, without extraneous noise and knocks. Check the operation of the control lamps in the instrument cluster.

Like all other mechanisms in the automotive system, the engine can also break down. It depends on many factors, most of which are by no means obvious and are found only by a specialist after a diagnosis, based on the “symptoms” described by the owner of the car.

The most common problems with a motor working with a carburetor system, we will consider further.

If you are not a fan of service stations and prefer to solve problems with your car on your own, you can easily determine the problem of tripping without outside help.

Remove the spark plug tip. With a decrease in idle speed, you can verify that the cylinder is working. But be careful: with such manipulations you will damage the switch or break through the cover of the slider, toggle switch. Do not worry, electric shock from the high-voltage wires of the automotive system is impossible in this case. But solely for security purposes, according to the principle of “God saves the safe”, the tips should be removed using pliers with handles protected by non-conductive material.

Reasons for tripping:

1. On the move over 1300 rpm, the shaking of the engine periodically stops. In this case, the afterburner or power systems may be the cause. The fact that failures do not occur with an increase in speed is explained by the inclusion of elements of the carburetor system, and since there are many of them, they will not all break down at the same time.
2. An equally common cause of engine tripping is the incorrect operation of the carburetor or, in some cases, the injector. This is either due to too rich or poor quality fuel. Leaning the mixture is more common, since they mostly save on gasoline, especially if the car is of domestic production.
3. If the mixture is of the required quality, but slightly exceeds the allowable rate, this indicates deformation of the tip on the needle that controls the fuel supply or fatigue.

Other breakdowns

If the VAZ-2109 engine is too hot, the problem lies in the unstable operation of one of the ignition or cooling systems.

Ignoring the situation after a while will turn into:

• the formation of sediment on the piston rings;
• breakage of the head of the block;
• deformation of the block head.

Any of the above breakdowns will result in expensive repairs.

Malfunctions in which the temperature of the motor rises:

1. The coolant level in the expansion tank is too low - top up the coolant to the required mark. Cold engine - MIN and MAX positions. If this does not help, look for a leak.
2. The thermostat is broken - the only way out is to replace this part.
3. Air lock - in the cooling system. They often occur after replacing one of the elements: a heater tap, a stove, etc. Put the car on an inclined plane and let the engine run in that position. After 15 minutes, all traffic jams will disappear.
4. Low quality, low octane fuel was used.

Other malfunctions:

• engine wear - piston rings wear out, which reduces compression, disrupting the combustion process of gasoline. Inexperienced car owners in such situations often begin to tune the motor in order to increase power, but they only make it worse - the mechanism breaks faster, working for wear;
• the car does not pull - the problem is with the intermediate shaft;
• the engine does not run smoothly - poorly tuned idle speeds in the carburetor.

If your car stalls or does not start, this does not mean that the engine is broken, the essence may lie in other elements and mechanisms that are associated with it. Fill your car with only quality gasoline and use the right oil, and the engine will last much longer even when it is not new.

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.

VAZ 2109 Samara

Description 2109

VAZ 2109 (Lada Samara) or "Nine" - a continuation of the front-wheel drive kind of Samara already in the face of a five-door hatchback. The model was created in 1987 on the meringue of the three-door hatchback VAZ 2108, and later, on the basis of already nine, the VAZ 21099 sedan was designed.

The wide popularity of this car is due to the fact that it had a swift design, good engines for that time and, most importantly, a practical five-door body. And in combination with a low price and a wide selection of spare parts, 2109 had no chance to go unnoticed.

It was these components that ensured high demand for the follower of the nine - VAZ 2114 . New fours continue to be wildly popular, mainly among the young part of the population.

Also, unlike the eighth model, the injector was installed as standard on the 2109 engine (engine 2111). In addition to the injection engine, carburetor 1.1 liters, 1.3 liters and 1.5 liters of working volume were installed on 2109. These engines are similar to those seen under the hood of the 2108.

As usual, we will examine the weaknesses and malfunctions of the VAZ 2109 engine, its repair and tuning, engine oil, problems, malfunctions, and more.
In the event that your motor has died and you need to pick up a new one, the information available will make it easy to determine which engine 2109 is worth buying, and which one is better to bypass and not get involved.
Everything for the owner of the nine is now in one place.
