Ulyanovsk Automobile Plant produces engines of several series, they were modified from engines with 4 cylinders. Initially, UAZ is a very passable car, however, according to many owners, the SUV lacks engine power. This problem can be solved by installing a V8 engine. This process is not the easiest, but the result will surprise you greatly. From this article you will learn how to install V8 on UAZ? What motors are popular?

How to install a V8 engine on a UAZ?

Most UAZ owners immediately after the acquisition begin to modify their car. Most often, they are limited only to the elimination of poor-quality assembly, but they do not touch the engine compartment. But a weak engine is the main problem of the Ulyanovsk Automobile Plant. This is especially noticeable on models with a diesel engine.

After the collapse of the USSR, used foreign-made cars began to be brought to our country. Many of them were equipped with a V8 engine. Some garage craftsmen decided to introduce this engine into a conventional UAZ. At that time, there was no "Patriot" yet, so all experiments were carried out with conventionalUAZs. As a rule, such experiments ended in failure, but there were also cases when it was still possible to realize what was planned. Also, there were cases when a motor from buses was placed in UAZs.

Popular motors to install

Most of all, engines from Nissan, Isuzu, Toyota cars are suitable for installation in UAZ. It was with these motors that the best specimens were obtained.

After studying the design features, in the end, the masters found the best option for installing the V8 on the UAZ-469. After that, the plant in Ulyanovsk began to produce a novelty of that time - the UAZ Patriot SUV. It was equipped with an Italian Iveco diesel engine. However, this did not last long, the domestic engine ZMZ-51432 replaced the "Italian".

How to install V8 in UAZ "Hunter"?

No matter how strange it may sound, but in our country there was a UAZ "Hunter" with a Japanese V8 engine. One well-known Russian blogger collected such a “miracle”. All this was made possible thanks to the help of experienced craftsmen. In total, the power of the UAZ V8 is 300 horses. The installed Japanese unit, in UAZ, still has a power reserve that can be realized by replacing some elements.

With this power, UAZ acceleration from V8 to 100 km/h is only 6.9 seconds. These figures are higher than some sports cars. By the way, the German crossover BMW X6 has the same acceleration in one of the trim levels. Outwardly, the UAZ "Hunter" remained almost standard, but under its hood is hiddenJapanese V8 engine, which is installed in many Toyota cars and is famous for its resource.

After installing a powerful engine in a regular Hunter, an automatic transmission was also required. However, after that it turned out that the chassis was not ready for such loads, and it also had to be improved. Through such changes, a rear-wheel drive UAZ V8 was made. Opinions of motorists on this occasion were very positive. The first tests took place at a special test site, where the car was carefully checked and only after that it left for the city.

ZMZ V8 Installation Instructions

Currently, for UAZ owners, installing a V8 engine is quite normal. Most often these are motors from GAZ-53 and 66 or from the PAZ bus. They are very easy to find, but most often they have malfunctions. Therefore, before installation, they are repaired. However, many have questions after installation:

1. The most important thing is fuel consumption. According to many, it is 10-12 liters.
2. It is also a very controversial issue about heating the motor, because it is not clear how to cool it.

To install a V8 engine on a UAZ, you will need to do the following:

1. Drill holes in clutch cover.
2. Dismantle the bells and drill holes in them for the V8 motor.
3. Cut threads for studs.
4. Dock the engine to the gearbox and cut down the front mounts.
5. Remove the old motor and radiator - it will be more convenient to work.

After installation, the effect will immediately become noticeable, andnamely: the power will increase, the motor will become more enduring, and its speed will increase.

Consequences of installing a new engine in the "Patriot"

UAZ SUVs are often found in which the engine from the GAZ-53 is installed. This engine has a power of 115 horsepower and huge torque. Its dimensions are comparable to the size of a standard UAZ engine, so installation will not be very difficult. Recently, this engine has also been installed in UAZ Patriot.

However, for the correct operation of the car, installing the engine will not be enough. It will also be necessary to install a new exhaust system, transfer case and gearbox. After completing all the work, you will immediately feel an increase in power. Now the SUV will be able to overcome any obstacles without much effort. Moreover, it will become more convenient and comfortable to travel by car on public roads. The speed will now pick up faster. You can verify this by reading the reviews of UAZ owners with a V8 engine.

This engine has one drawback - it is noisy. But this minus repels few people from installing an increased power motor. In addition, initially the UAZ "Patriot" has a rather weak sound insulation, therefore, by improving it, you can forget about the drawback.

Pros of installation

Installing a V8 engine in a UAZ entails a number of advantages:

1. High revs coupled with high power while driving provide more confident driving and good flotation.
2. Though the motor makes noisemore than the standard, but at the same time it has much less vibrations.
3. On asph alt, the car handles better and picks up speed faster.

Cons of installation

Installing a V8 engine on a UAZ is also accompanied by disadvantages:

1. Resonators won't fit, so a silencer will have to be installed.
2. Noises appear when revving high, however, like most cars.
3. The bridge may hit the pallet. As a rule, this rarely happens in practice.

The advantages are much more significant than the disadvantages. That is why owners of UAZs with V8 recommend this unit for installation.

Tuning

What are the possibilities of tuning UAZ V8? Any tuning is best to start with a “hodovka”. And the cases with the UAZ car are no exception. After all, the speed qualities and cross-country ability of an SUV will depend on this. The best option would be to install a 3-liter engine. It will be enough to increase patency. For more stable operation of the motor, you can install iridium candles. If the engine power is still not enough, then the cylinders can be bored. Do not forget about the quality of the fuel and the cylinder ventilation system, then the engine will work for a long time without any problems.

Ventilation is very important, because the performance of the entire unit depends on it. To improve it, it is recommended to install a snorkel going to the roof. It is also not uncommon for the engine to be injected with an increase in its power to 130 horsepower.

Desirablealso modify the gearbox and transmission, namely: install a short main pair. Thanks to this, the gearbox will work better. It is also best to use larger wheels on wide profile tires to raise the car and improve flotation. For this purpose, you can install spacers or change the entire suspension.

A couple of words about "Patriot"

Ulyanovsk Automobile Plant produces "Patriots" with various engines. One of them is a gasoline "aspirated" ZMZ 409.10. The volume of this power unit is 2.7 liters, and the power is 135 horsepower at 4600 rpm, despite the fact that the cutoff is already at 3900 rpm. The torque of the motor is 217 Nm. For the Patriot, the power of such an engine is sorely lacking due to the weight of the SUV, but for the Hunter, these indicators are quite enough to successfully overcome obstacles.

Also, a ZMZ 51432 diesel engine is installed in the Patriot. Here, traction is better from the bottom. Such a motor is not suitable for heavy mud and snowdrifts. Off-road it is difficult for him to drive even in the first low gear. And this is the case when installing larger wheels with wide tires will only make matters worse.

Which choice to make?

There is no exact answer to this question. But recently, in the Moscow region, they found the most suitable option for installation - this is a Chinese-made Cummins ISF turbocharged diesel engine with a volume of 2.8 liters. It certainly does not have as much power as other engines - only 120 horsepower at 3200 rpm. However, unlike other options, this motorhas a huge torque - 295 Nm, which can be realized already at low speeds.

This motor is also often found in Sables. And its power is quite enough, despite the fact that the car has four-wheel drive.

It is worth noting that the Cummins ISF 2.8 liter engine is common, so finding spare parts for it will not be a big deal. It is installed on many GAZ models, including the Gazelle. It can be installed with or without all-wheel drive. The cost of such a motor is relatively low. Parts are also cheap. Many car services have masters who know how this motor works, and in case of a breakdown, they will repair everything.

Sometimes Japanese-made engines are installed in UAZs. In this case, the motor must be looked for and chosen carefully, since most of them are already in a deplorable state. Bringing an engine from Japan is quite expensive, as the customs fee will be huge, which is why no one does it.

Solving installation problems

The main problem that occurs during the installation of the Cummins ISF 2.8 motor is quite serious. It is associated with the structural features of the motor, namely with the oil pan. When the suspension is working at full speed, the motor hits the front axle with a pallet. To solve this problem, it is necessary to install larger engine mounts. After that, no problems should arise.

Conclusion

For tuning UAZ "Patriot" installation of the motor is not enough. Of course, this will increase its permeability, butto improve performance, it is necessary to install wheels with a larger diameter and tires with a wide profile. In order for them to fit, you need to increase the clearance. This can be done in different ways. After such improvements, the car will be able to overcome not only off-road and snow, but also swampy terrain.

To raise the car, it is advisable to replace the rear axle and install shock absorbers with springs instead of springs. Since the suspension and wheels are different from the standard, you will have to install disc brakes for your own safety.

UAZ "Patriot" is a good SUV for a country road or countryside. However, it is completely unsuitable for a professional Off-Road, but if you change its insides a little, you get a pretty good option.

The V8 engine for UAZ is time-tested and has good technical characteristics and feedback from motorists, is unpretentious in maintenance and pulls well. He showed himself in a very good way. It is also considered very economical.
