Diesel for Niva Chevrolet: installation and calculation

Diesel Niva: which engine is suitable

This is due to the fact that the original VAZ gearbox will not be able to withstand the loads that the diesel unit will create on it. Instead of a VAZ gearbox, a Fiat Polonaise gearbox is often installed.

It is used because the same XUD-9SD unit was installed on the Polonaise. The clutch housing is also installed together with the gearbox. In addition, owners who convert the Niva to the XUD-9SD diesel engine also additionally change the front mounting supports of the unit.

The pallet also undergoes transformations. The exhaust system will also need to be redone. To ensure additional reliability of front-wheel drive elements, some parts are replaced with similar ones from Chevrolet Niva.

To ensure proper cooling of the power plant, the standard radiator is often replaced with a radiator from a Gazelle. At the same time, the rubber pipes are also changed. It wouldn't hurt to install a diesel fuel heating system in winter.

Self-installation of a Peugeot engine

There are also Nivas on which the owners install diesel engines themselves, or they turn to specialized service stations that replace engines.

There are a large number of options for which diesel unit to install on the Niva. The most common is the same diesel XUD-9SD from Peugeot. As a result, it turns out that version 212151 is created from a regular Niva by replacing the engine.

This diesel engine is the easiest to install on a car, since the mounting points on the XUD-9SD are exactly the same as on the original gasoline engine. It is worth considering that in addition to replacing the engine itself, some modifications have to be made. There is also the possibility of installing the XUD 11 power unit, produced by the same Peugeot, on the Niva instead of the XUD-9SD.

In addition to the engine itself, the gearbox will also need to be changed. This is due to the fact that the original VAZ gearbox will not be able to withstand the loads that the diesel unit will create on it. Instead of a VAZ gearbox, a Fiat Polonaise gearbox is often installed. It is used because the same XUD-9SD unit was installed on the Polonaise. The clutch housing is also installed together with the gearbox.

In addition, owners who convert the Niva to the XUD-9SD diesel engine also additionally change the front mounting supports of the unit. The pallet also undergoes transformations. The exhaust system will also need to be redone. To ensure additional reliability of front-wheel drive elements, some parts are replaced with similar ones from Chevrolet Niva.

After all these alterations and modifications, documentation will be required at the State Traffic Inspectorate.

Niva with a diesel engine - which engine can be installed?

Re: Diesel engine installation issues. If it has an XU9 engine, then this is a very common diesel engine, because it was installed not only in Peugeot, but also in Citroen and Fiat. We have more spare parts for it than for VAZ engines. And they installed it in NIVU because there are minimal alterations, the oil intake is located in front, and not in the center like most diesel engines, and some even have it in the back. The oil filter is on the front left, just like the NIVA. in Japanese engines, for example, it is in the center and on the right. All that remains is to remake the pan, well, the oil intake will also have to be done, the flywheel, the adapter plate for the gearbox, and of course the engine mount and RPM.

NIVA Diesel with Peugeot engine

A Niva with a diesel engine is no longer a dream - it’s a reality. You can touch it with your hands and take a picture. You can even ride it if you're lucky.

PSM has long and successfully offered everyone “a wide range of diesel, gasoline, and liquefied gas engines with power from 20 to 200 hp.” The Volzhsky Automobile Plant has long been looking for a diesel engine that would fit perfectly into a VAZ car. And although PSM’s proposal was not the only one. The choice fell on this company. Why? We asked Vladimir Trofimov, deputy technical director of the Lada-Export joint-stock company, to answer this question - a company created, according to him, to work out all modifications of the VAZ car that the market requires, but cannot be made on the Volzhsky Automobile Plant's production line.

The choice of PSM engines is not at all accidental. This company is well known and reputable. It is a branch of the Peugeot-Citroen Automobile group, which has two divisions - Peugeot and Citroen, which produce cars of the same name.

PSM engines, especially diesel ones, are known throughout the world as the most economical and environmentally friendly. They have a very well-developed design of the exhaust emissions reduction system, eliminating the need to install additional catalysts, neutralizers and other devices. That is, this engine is environmentally friendly. It is sold on the French market under the “green” brand, and therefore its installation on our car immediately eliminates the toxicity problem. And this, as you know, is now the most relevant in the European market, especially for VAZ.

The second argument in favor of choosing a partner was the following circumstances: PSM is the world's leading manufacturer of diesel engines: the company produces 800 thousand engines per year. This is a leader, everyone focuses on him, and working with him has allowed us to reach a level that does not raise any doubts among customers either about the quality of engines or about the capabilities of cars with these engines.

The fact is that PSM is precisely designed to adapt its engines to any brand of car. It supplies engines to Rover and many European and Italian brands produced in small quantities, including all-wheel drive ones. And the company’s policy, like the policy of the Volzhsky Automobile Plant, is to work directly with designers, without an intermediary.

Diesel in the field: solving the problems of self-installation

If I understand correctly, these kits offer brackets for mounting the front axle to the engine adapted to several imported diesel engines, and if so, which ones exactly?

Brackets for independent fastening of the RPM are not tied to any specific engine; they are universal, since the RPM is attached to the front axle beam and to the stabilizer.

The main disadvantage of these engines is the complexity and high cost of repairing the fuel system, since a number of units use parts with high precision processing. Content

Factory Niva with a diesel unit
Self-installation of a Peugeot engine
Other engines

Return to contents Factory Niva with a diesel unit Initially, the developers made attempts to install domestically produced diesel engines on the Niva 2121. This diesel engine had a combustion chamber volume of 1.5 liters and was turbocharged. But the idea of a domestic diesel engine for the Niva failed. The reason for this was its low power. Niva 2121 with this engine was not capable of efficiently covering off-road conditions. There were attempts to install domestic diesel engines on the Niva, the volume of which was increased to 1.08.9 liters.

Factory Niva with a diesel unit

Initially, the developers attempted to install 2121 domestically produced diesel engines on the Niva. This diesel engine had a combustion chamber volume of 1.5 liters and was turbocharged. But the idea of a domestic diesel engine for the Niva failed. The reason for this was its low power. Niva 2121 with this engine was not capable of efficiently covering off-road conditions.

There were attempts to install domestic diesel engines on the Niva, the volume of which was increased to 1.08.9 liters. Moreover, they were installed on the Niva 2121 in both 3-door and 5-door bodies. But these were experimental models that never made it into mass production.

The way out of the situation was to install a foreign-made model. As a diesel engine, the Niva began to be equipped with a Peugeot engine with the factory index XUD-9SD. It was quite common and was installed on many cars.

Diesel engine

The main advantage of this diesel engine was excellent traction at low speeds, which allowed the car to easily overcome off-road conditions and dirt. At the same time, the Peugeot diesel unit was reliable and had good maintainability.

The maximum speed for the Niva 2121 with a Peugeot engine was set at 120 km/h. But the dynamics during acceleration were not up to par. The speedometer showed a speed of 100 km/h only after 25 seconds. But this indicator is not so important, since for the Niva 2121 high cross-country ability is much more important than speed characteristics.

Niva 2121, on which a diesel unit from Peugeot was installed, was produced until 2009, after which its production ceased. Since the Niva diesel was an export option, it is rarely seen here. Those cars that can be seen on our roads are most often re-exported.

Test forum

Which used diesel engine is easiest to install on a NIVU? Hello dear experts! Happy New Year. Please recommend which used diesel from a foreign car from the 90s, the easiest way to install it on a NIVU of the 2121 family. I really need a cheap off-road vehicle, the choice fell on the NIVU, it suits everyone, except for the presence of a gasoline engine! Therefore, the idea was born to buy a carburetor NIVU and put a diesel engine in it. To purchase a diesel engine, I plan to buy an entire diesel foreign car from 1990-2005 abroad and, having removed the engine from it, bring it to Russia (fortunately, the cost of such foreign cars and customs clearance for diesel are cheap). The question immediately arose, what brand, model and year of manufacture is best to look for a foreign car, so that when introducing its engine into NIVU, make as few alterations as possible...

An SUV with all-wheel drive, produced by a domestic automobile company under the Niva brand, is equipped with a gasoline engine. Although the manufacturer intended for the Niva to use a diesel engine. True, the intentions were partially realized.

Some automotive experts are of the opinion that if you try and follow specific rules, you can install a diesel engine in a field.

Attempts by the plant to install diesel

The manufacturing plant made attempts to install a diesel power plant on the Niva-2121 car. It was planned to use a 1.5-liter turbocharged engine. Cars equipped with such engines that underwent testing turned out to be low-power. But attempts to equip all-wheel drive with a promising internal combustion engine continued. The Chevrolet Niva diesel car, which turned out to be unpromising, was equipped with a large-volume engine.

Soon the factory workers abandoned attempts to equip the SUV with a diesel power unit. The model remained out of series.

Calculation for a foreign internal combustion engine

Car production engineers did not abandon the idea of adding a foreign diesel engine to the Niva. The choice fell on the French Peugeot xud9sd with a power of about 80 horsepower. The choice of Russian specialists was motivated by the simple design of the diesel engine. Foreign engines have longitudinal cylinder placement. There are 4 of them, with a working volume of 1905 cubic centimeters.

During testing, the installed engine showed the following characteristics:

power at peak torque was 70 horsepower at a crankshaft speed of 4600;
the car reached a cruising speed of 120 kilometers per hour;
Fuel consumption when driving a car for 100 kilometers was 8.7 liters.

Experimenters who installed a foreign diesel engine in the field obtained excellent results:

The Russian Niva Chevrolet diesel turned out to be not only an economical model, but also showed excellent off-road performance;
Moreover, at low speeds it demonstrated powerful torque, which is important for driving on country dirt roads;
The positive results were complemented by simple repairs and maintenance of motors.

During the testing process, negative aspects also emerged:

The slowness of acceleration in dynamics at 10 meters was revealed;
The installation of an imported diesel engine into the Niva confirmed fears that the car would accelerate slowly from the start. On the autobahn this is a significant mode for the driver, but not significant when driving on total off-road conditions.

Based on the results obtained, it was decided to put the car into mass production. But they came off the assembly line in limited quantities. It was never sold in Russia, since the entire series was sent for export. 9 years ago, the assembly line of the Niva 2121 car with a diesel engine stopped.

Diesel engine for Niva Chevrolet

Some car owners transferred power units from other cars to the Chevrolet Niva. Although experienced mechanics from car service centers say that this car is already good together with the power unit already installed in it.

Let's look at which diesel internal combustion engines are suitable for a Chevrolet Niva car without modifications, and which ones with modifications. And we find out what needs to be improved most often.

Options without modifications

To install a diesel engine on a Niva car without modifications, you will need to find a power unit from a Peugeot car. The gearbox is most often left original. But many car owners install cars developed by Aisin or Fiat. As they say, if we’re going to redo it, then it’s the engine and gearbox.

Attention! There is a version that a VAZ gearbox with such an engine will not last long. However, everything depends on the driver’s behavior on the roads and how he operates the car. For many car owners, the gearbox supplied from the well-known company Aisin cannot handle it.

This engine is installed on the Chevrolet Niva without modifications. However, the engine still won’t fit perfectly into the installation location. The suspension will need to be strengthened a little. Since I already said that this motor is heavy.

We'll have to modify the rear mounts for the motor. Experienced mechanics recommend additionally installing a heating system. Because in Russian winter conditions, the engine will not be able to start with half a kick.

By the way, the factory Niva models with a diesel engine are equipped with a Peugeot engine. The working volume of this engine is 1.9 liters. Torque is 195 Nm. And the engine power has been increased to 90 horses. By the way, fuel consumption is reduced as much as possible. Average consumption per 100 km is 7.5 liters.

Modified options

Many car owners say that a Niva can be equipped with an engine with maximum modifications, and it will be better than the one installed from the factory. Although this is a controversial statement. You will spend the same amount of time and money installing a power unit with modifications, so it’s better to buy a new car and not worry about it.

If you install a modified engine on a Niva 2121, then here are the points that need to be modified:

installation of new support pads;
alteration of the bell at the gearbox;
reworking the pallet;
installation of a new flywheel and oil intake;
The entire exhaust system is being changed.

Some car owners, in addition to replacing the engine with a diesel one, additionally install a turbine on it. This increases the power of the car, but in this case the gearbox changes. Moreover, the gearbox must match the engine so that it does not break under the load.

Attention! If a turbine is installed, the transfer case will also have to be replaced. Otherwise, it will also simply be torn apart by the incoming power.

Experienced mechanics advise those who do not like to risk installing a diesel engine from a Mercedes. This power unit is reliable, although budget-friendly and not very powerful.

Many experienced mechanics do not recommend changing the engine on a Niva. Since the car is made according to Soviet patterns with a different power unit, it can pose a danger to the driver. For example, if the engine exceeds 120 horsepower, the car may simply fall apart on the road.

Therefore, car owners who prefer Soviet and Russian production install diesel from Lada Priora. It has a lot in common with the Niva, but the bending of the valves will be a serious disadvantage, which you also need to pay attention to when choosing.

It is known that a broken timing belt bends valves in Priora engines. And the lifespan of such belts in diesel engines is no more than 70 thousand kilometers. If you regularly undergo maintenance, then you will not be in danger of a sudden belt break.

Hybrid Niva

We began to develop the official version of the Niva for integration into the engine compartment of a diesel engine in a tuning studio in Tolyatti. The legal entity has acquired a recommendation - permission from the plant -. Refinement processes began to adapt the Italian Fiat diesel engine along with the Aisin transmission, produced at one of the Japanese factories.

The competent installation of the Italian diesel engine was a success and showed positive results in test tests:

The power of the power plant reached 90 horsepower.
Peak torque stopped at 195 Nm.
For 100 kilometers the car required only 7.5 liters of diesel fuel.

In practice it turned out better than expected. The combined diesel Italian-Japanese Chevrolet Niva was a great success. In terms of the main technical parameters, the quality is very close to the factory assembly.

One bad news is that the cost of adaptation was high.

Do-it-yourself diesel for Niva

Let's try to place a diesel analogue in the engine compartment of a car instead of a gasoline power plant. It is impossible to successfully integrate the internal combustion engine without the help of a tuning studio. You can use private specialists who know a lot, who personally carry out modification tasks to replace a gasoline engine with a diesel version.

If a car enthusiast is good at technical matters, then he can replace a diesel engine himself with a gasoline engine. You just need to acquire special tools. And at the same time prepare for registration of changes made in certain structures of the traffic police.

Worth thinking

Before starting work, you should discuss with professionals which brand of diesel is best. There are many of them on specialized liquid trading platforms. Practice provides an example in choice. According to statistics, preference is given to diesel engines produced in the Land of the Rising Sun, at factories of United Europe. The main principle of selection for the Niva is compliance with physical parameters, that is, reliable fastening in the engine compartment of the car, without disturbing the alignment of the power unit.

The weight of the diesel engine also matters. If it weighs more than a standard gasoline engine, then the load on the front axle and suspension will increase, which will lead to negative consequences. The variable gearbox also needs to be replaced.

For a standard fit in the engine compartment of a diesel engine, it is necessary to replace:

landing pins;
adapt the engine sump to the metric dimensions of the car;
bring the exhaust system components into new compliance;
The cooling system is subject to modernization, requiring replacement of the radiator.

Rearranging the Gazelle does not require dismantling the radiator, since its fastenings and other metric parameters are ideal for a diesel engine.

Additional nuances

Some components and parts are replaced with stronger analogues in the chassis of the car. For normal diesel start-up on Niva in winter, devices are installed that heat diesel fuel.

A suitable replacement diesel engine is the French imported Peugeot xud9sd engine. Its fasteners almost coincide with the domestic power plant. The mounting pins almost perfectly match the holes and diameters for the mounting bolts, which will significantly simplify the replacement of a domestic gasoline engine with an imported analogue that runs on diesel fuel.

Among Japanese diesel engines, power units with the Toyota 3c/ct index are promising. Depending on the purpose, they are produced with a power of 90 and 100 horsepower.

Features of installing a diesel engine on a VAZ 2121

If the manufacturer does not provide the opportunity to buy a Niva with a diesel engine, then craftsmen will appear who will install it with their own hands. So, which diesel engine is suitable for the VAZ 2121? Here are the most popular models:

Peugeot XUD-9SD (1.9 l, about 70 hp) together with Fiat Polonez gearbox.
Peugeot XUD 11 with Fiat Polonez gearbox.
Toyota 3C (79 hp) or 3ST (100 hp) together with Toyota Noah gearbox.
Motor from Volkswagen Vento.
And many others.

To install a diesel engine, a large number of modifications will be required. The simplest and most common way of such tuning is to use the engine that was installed for export versions of the SUV (XUD-9SD). Its installation requires the least amount of changes to the machine design. It has a good location of the oil intake (in the front, not in the center or rear), the oil filter (on the front left, like the Niva) and attachment points to the body. In addition, it is easy to find spare parts for this engine model. The approximate procedure is as follows:

Engine mounts fit from Niva 21215.
The gearbox bell and the box itself fit well from Fiat Polonez.
Rework the pan, oil intake, flywheel, exhaust system, etc.
The easiest way is to complete all the modifications according to the documents.

In other words, no diesel engine can be installed instead of a gasoline engine without modifications. What do you think, is it necessary to change the Niva’s internal combustion engine to a diesel one? If yes, which one and why? Let us remind you that you can improve off-road performance in an easier way, for example, by installing mud tires.

When in 2009 it became known that a batch of Chevrolet Niva diesels were to go on sale, there was some optimism among domestic car enthusiasts about this, because for an SUV, a diesel engine is more appropriate than a gasoline one. But quite a lot of time has passed, and for some reason this model has not become widespread. Let's try to understand the reasons for this.

Let us immediately note that the author of this project was not GM-AvtoVAZ, but located in Togliatti and specializing in Niva tuning. GM-AvtoVAZ only allowed to release this car under the sign of its brand, and even then with difficulty. And as it turned out, it was in vain.

This is one of the reasons for the unpopularity of the new diesel Chevrolet Niva, since a large number of motorists are far from enthusiastic about the products of this company.

Let's take a look at the technical characteristics of this machine. In fact, it differs from the regular gasoline Chevrolet Niva only with a new diesel engine. Here are the technical characteristics of the Niva Chevrolet Diesel:

volume is 1.9 liters;
turbocharged engine power 120 hp. With. without it - 100 horsepower;
the maximum torque is 195 Nm and is achieved at 2600 rpm.

Niva Chevrolet Diesel is all-wheel drive , it is possible to disable the rear axle. The front hubs are not adjustable. Instead of crosspieces, the cardan transmission is equipped with CV joints. The Japanese kindly provided a gearbox for the diesel Niva. Power steering can be considered a functional plus, as can the built-in air conditioner.

But still, many Chevrolet Niva (DIESEL-TURBO) owners are dissatisfied with the car. Some of them say that the sound of a running engine makes you feel as if you are driving a combine or tractor. Manufacturers counter with the fact that, in fact, a diesel engine is no louder than a gasoline engine, and this feeling arises due to the fact that the vibration frequency of the new engine and the human voice are almost the same. Because of this, the sound of his work is perceived “brighter”.

Our person also did not like the gearbox, because it has a rather short stroke. Also, many are saddened by the need to wait about five seconds each time they turn on the ignition until the Check engine light turns off, and only then start the engine. During this pause, the glow plugs begin their work.

But the most significant drawback is definitely the price of the machine. For a brand new Chevrolet Niva (DIESEL-TURBO) you will have to pay 597 thousand rubles .

After all, if you do the math, it’s worth investing a little more money, and you can buy a foreign SUV that will definitely surpass the Niva in quality, characteristics and functionality. And for 600 thousand you can buy a used SUV in acceptable condition.

We install a diesel engine on a Chevrolet Niva ourselves

The idea of installing a diesel engine on a Chevrolet Niva was not new at the time the model described in the article was released. After all, this type of engine really has a number of advantages, namely:

fuel consumption per 100 km is 7.5 liters;
for a gasoline engine this figure is around 12 liters;
increased traction at low speeds provides the SUV with higher cross-country ability.

Video review of our diesel Niva

To improve the performance of your car, you can install a Niva engine from a foreign car without modifications. The VAZ-2121 has long been considered one of the best domestic cars both in terms of engine power and driving performance. But now this car model has become outdated, and many motorists are trying to somehow improve it. What engine should be installed as an analogue to the 1.7 liter petrol injection engine?

What diesel engines did AvtoVAZ install on the Lada 4×4?

Diesel engines for Niva cars have a number of advantages. Experienced mechanics installed diesel internal combustion engines from other cars that were suitable in size and looked at what advantages the car received from them.

The best and most popular Niva engines were:

Peugeot XUD-9SD (1.9 l, about seventy horses). It was installed with a Fiat Polonez gearbox.
Peugeot XUD 11 with Fiat Polonez gearbox.
Toyota 3C (79 horses) or 3ST (100 horses). This internal combustion engine was installed on a Niva with a gearbox from a Toyota Noah vehicle.
The engine is from the German workhorse Volkswagen Vento.

Only one motor required minimal modifications. It was the XUD-9SD. This engine had a well-placed oil intake and oil filter device. And also the mountings for the internal combustion engine were located exactly at the points where the old gasoline power unit was attached.

However, it was considered heavy for such a machine. Therefore, many craftsmen ignored the Peugeot engine. Many are trying to install the VAZ 341. However, there are dark rumors about this engine. For example, those craftsmen who finally installed this engine on a car then spit because they constantly have to modify or change something. Either the cylinder head breaks, or the liners have to be changed, and much more similar to these breakdowns. Although the engine itself runs smoothly without any complaints.

Replacement problem

The fact is that to replace the engine on a VAZ-2121, you can choose almost a dozen different engines, but they are all from foreign cars. But the main problem is that you will have to do some additional work during installation, for example, install or change fasteners, add new parts. Because of this, it is not so easy to find a budget replacement option. The choice is significantly narrowed down to just a few options. For an engine to be suitable for installation, it must meet several conditions:

Which engine should you consider first?

Improved Niva

The injector installed on the Niva, although it reduces fuel consumption, is still not the most economical option in urban conditions with traffic jams and other delays. On the highway and during long trips outside the city, this is not felt so much, since the car works without stops and downtime. Due to the unprofitability of cars in urban environments, drivers are thinking about a good and effective replacement for the old injection-type engine in their car. The best option would be a diesel engine for the Niva. It has approximately the same power characteristics, but its fuel consumption is comparatively lower. Also, diesel is less capricious in terms of fuel quality. What options from this category of motors are worth detailed consideration?

The first and most worthy candidate is the XUD 9 SD from Peugeot. This engine was used to create a modified version of the Niva - model 212151 with a French engine. It can be installed on the Niva without any problems - the fastenings of the parts and the assembly are identical, the motor fits perfectly in size, and in addition, there are some advantages from its installation.

In fact, this is the only option that suits all parameters.

Installing a diesel engine on a Niva

One of the available options is the independent installation of a diesel engine on the Niva. To do this, you can use the services of large tuning studios or private professionals who modify cars. You can also install a diesel engine on a Niva yourself if you have some experience and specialized tools. You need to be prepared for the fact that in order to legally operate the car after replacing the engine, you will definitely need to register the changes made with the relevant government agencies.

In the process of selecting a diesel unit, many people wonder which diesel engine to put on the Niva. There are a sufficient number of diesel engines that can be installed on this car. Diesel engines of Japanese and European brands are most often installed on Niva with their own hands. The main requirement is the suitable physical dimensions of the power unit for placement in the engine compartment of the Niva.

The need to make changes to the design begins with the mounting features of the diesel engine. The second nuance is the increase in load on the front axle after installing a diesel internal combustion engine on the Niva, since an engine of this type is often heavier. For this reason, it is necessary to further strengthen both the suspension and the body after placing the engine. Almost always, the standard gearbox will also need to be replaced.

The list of general changes to the design of the Niva for a diesel engine includes: replacement of front engine mounts, modified sump, changes to the exhaust system. The engine cooling system is also subject to modernization. The cooling radiator is often changed (a radiator from a GAZ Gazelle car is suitable).

Changes are also being made to the chassis, individual elements are replaced with reinforced ones. For a regular Niva, they can be borrowed from Niva-Chevrolet. As for the operation of diesel engines, it is separately recommended to install a diesel fuel heating system.

You can also install a Peugeot diesel engine with the xud 11 index on the Niva, but in this case the gearbox will need to be changed. The VAZ gearbox with this engine will not last long. The solution is a gearbox from the Fiat Polonez model. Additionally, you will need to install another clutch. No less often, diesel engines from Japanese cars are installed on the Niva. Units with the Toyota 3c/ct index with a power of 80 and 100 hp are suitable. To replace the gearbox, you can use a 5-speed gearbox from the Noah model manufactured by Toyota.

The best option would be a diesel engine and gearbox, which were originally designed to work in tandem. In this case, the task is simplified due to the correspondence of all attachment points, as well as the coincidence of the axes of the internal combustion engine and transmission shafts. This approach eliminates difficulties in the process of combining a diesel engine and gearbox, and also significantly increases the service life of the associated components. There is no need to calculate what torque a particular gearbox with different diesel engines can withstand.

Modified options

Since it is not always possible to supply an engine of a certain foreign car, it is worth considering imported production options that require a little modification:

The first candidate will again be the French engine from Peugeot XUD 11 series. Since the power of this unit is higher than that of the previous model, some changes will need to be made to the design of the Niva - replacing the gearbox. An acceptable option is a gearbox from Fiat Polonez. In addition, a good solution would be to replace the front supports of the power plant fasteners, pan and exhaust system. It is also worth replacing the drive elements with similar parts from the Chevrolet Niva.
