To fix the gearbox, we insert a wooden block of a suitable size between the clutch housing and the anti-roll bar.
We install the engine on the car in the reverse order of removal.
When connecting the engine to the gearbox, the input shaft of the gearbox must fit into the splines of the clutch driven disc.
What is the best engine to install in NIVU to replace the original one?
Every motorist dreams that the engine in his car would be more reliable and stronger. Owners of NIVA
They know firsthand that sometimes just a little bit of power is not enough to pass some obstacle.
In the standard NIVA,
the engine is rather weak and everyone knows this; in one of the posts I talked about how to inexpensively increase the power on a NIVA by 40%.
Someone like this tuning
It seems unreliable and tedious.
Therefore, Niva
go a different route and install engines from other cars.
So, 3 engines with better qualities than the original Niva engine.
1.
Probably the most
reliable and budget
option is to install a
Toyota
2-liter 3S
petrol .
Perfectly fits the NIVA
with minimal modifications.
are also installed from this engine .
reviews of such a converted
NIVA
; everyone who has this internal combustion engine installed, I think that this engine was created for
the NIVA
.
2.
This motor is very easy to install and
does not require
huge investments and effort for installation.
For this motor, the Russian market already has all the necessary spare parts for a “swap”
.
Yes, you understood correctly, this is a VAZ 16 valve engine
.
The advantages of the engine are more powerful and lower fuel consumption. Niva
owners with such
a “heart”
recommend changing
camshafts “for traction”
.
3.
Diesel engine from
PEUGEOT.
XUD 9 is a 1.9 liter engine that NIVO drivers really loved.
This unit is installed on NIVU at the factory
, but these models are exported (read here).
This engine is also installed on the car practically without modifications
.
Only in price it will be more expensive than the internal combustion engines
presented above.
We would like to know your opinions:
Is it worth changing the engine on Niva?
What alternative should I buy instead of NIVA?
Share your opinion in the comments.

VAZ 341
Few people know, but VAZ had a limited production of diesel engines. They were installed on diesel “fours”. The engine turned out to be quite high-torque and economical, and given the original 2103 block, there will definitely be no problems with installation.
Among the shortcomings, it is worth noting the very short resource of this motor, and it is not possible to find it now. But fans can try.
Engine for Niva from a foreign car without modifications
When buying a Niva engine from foreign cars, many new car enthusiasts are interested in whether the engine from a foreign car will fit into a domestic car without modifications. Despite the fact that the Niva is a vehicle that can pass any road, thanks to its ground clearance of 20 centimeters. And the volume of the power unit of 1.7 liters will not allow you to spend extra money on gasoline.
What else can be done to improve?
Experts do not recommend chipping a naturally aspirated engine. You can further increase engine power if you try to increase the piston stroke. This can be achieved by installing another crankshaft with a stroke of 84 mm, suitable for the VAZ 2130
. The piston has a diameter of 82 mm, but the piston pin must be offset by 2 mm. After this, the working volume will become 1.8 liters. In the future, if you bore the block to 84 mm. with the same crankshaft, the volume will become 1.9 liters. But that’s not all, in the future you can increase the filling capacity of the working cylinders. This is achieved by boring and installing valves with an increased diameter of their plates. This operation is quite complex and requires special equipment. It is also advisable to use lightweight connecting rods and then you can have about 100 horses at the output.

Attention! The closer the Niva engine is produced to the year in which it lives, the higher the environmental class.
The Niva's fuel consumption is as low as all small cars. Car owners often change their gasoline engine to a diesel engine for their Niva Chevrolet. Let's take a look at the advantages obtained by installing this engine and the negative aspects that the owner has to face.
A few words about the standard engine
The modernized engine received the index 2123, it was changed only because of the engine compartment, but everything remained from the old engine and is easily interchangeable with 21214. Its production began in 1994, the block is made of cast iron. The head has two valves per cylinder, the pistons were installed with a diameter of 82 mm, and their stroke remained the same and equal to 80 mm. The increased diameter of the piston made it possible to increase, albeit slightly, its power; it became equal to 81 hp, with a compression ratio of approximately 9.4.
When operating at a speed of approximately 3,000 per minute, the maximum possible torque of 125 NxM is obtained. The fuel recommended by the plant is AI 93 gasoline, but its appetite is somewhat voracious, ranging from 10 to 12 liters per 100 km. mileage Its mass is 117 kg. The design provides for an overhead camshaft and a timing chain drive.
In the new Niva, they changed the method of installing the unit in the engine compartment, as well as the location and fastening of attachments. As an advantage, we can note the installation of hydraulic compensators for valves and a chain tensioner. Disadvantages include noise and slight vibration of the engine. Manufacturers claim its resource is approximately 80,000 km. mileage, but practically it is much higher and can reach up to 200 thousand.
Diesel engine for Niva Chevrolet
As a replacement, a diesel engine is used for the Niva. Such a motor provides the following advantages for the car:
- traction performance at low speeds increases. The car does not slip in the mud on rural roads or on asphalt with wet snow in the autumn. Good performance in the last parameter is also determined by the installation of high-quality studded tires;
- Niva fuel consumption decreases when traveling on rural roads and the highway;
- the lifespan of the engine increases.
However, there are also disadvantages to installing a diesel engine on a Niva. The weight of the car increases, and in city mode this affects the increase in fuel consumption. Vibrations from the diesel engine are transmitted to the body. A diesel engine from a foreign car requires replacement of foreign-made parts. Therefore, the cost of repairing such a power unit increases.
What diesel engines can be installed on the Niva in the list:
- Peugeot XUD 9SD;
- Peugeot XUD 11SD;
- Volkswagen Vento.
Together with the installation of the above-described engines, a gearbox from Fiat Polonese is suitable. It will take a little work to remodel, but it's worth the effort.
What you will need to do:
- Install pillows from VAZ 21215.
- Install a bellhousing and gearbox from an already known Fiat.
- Slightly alter the pan, oil intake, flywheel and some other parts.
- All changes must be submitted through the traffic police.
After such tuning, you will not need to invest in the car for another five years. The only thing that is needed is to observe regular technical inspection and preventive replacement of consumables: filters from air to diesel, oil seals, if the machine was used in difficult conditions, for example, such as heat and frost below 20 degrees Celsius with a minus sign.
Let's now see which engine can be installed on the Niva, but without making modifications and without completely reinstalling the “heart” system of the engine. Some of the engines listed above still have the ability to fit without modifying the space for the engine. Let us describe in more detail why these engines are good.
Options without modifications
The Chevrolet Niva will be equipped with the Peugeot XUD engine without modifications. Replacing with this power unit is better than installing the original new engine. Firstly, it is more durable than the one that was originally installed on the Niva. Secondly, a dozen different engines will be inferior in terms of power and maintainability compared to Pezhovsky. You don't have to replace many parts to get the motor to fit into the car and interact with the wheels and transmission.
Another disadvantage of this engine is its high cost. It is installed on Niva cars for export. Therefore, parts for it have a high price.
The remaining diesel engines are installed with modifications.
Modified options
Engines on the Niva with modifications are already coming from Toyota and Volkswagen. I wrote about them above and how they need to be changed so that the engine works properly was also described. However. If you do not understand the design of power units, then it is better to leave the replacement procedure to experienced mechanics.
Therefore, I will not go into details. I’d rather write what you need to know when swapping an engine for diesel or gasoline:
- the power unit must be freely placed under the hood in the engine space of the car;
- The maximum permissible excess power is no more than 20 horses. Otherwise, other parts of the car will not withstand the load;
- swap should be useful.
Now let's talk about gasoline power units.
Niva 3S automatic transmission, automatic (part 1)
Niva
21213. Installed ICE-3SFE (2l), automatic transmission (automatic transmission), steering rack, power steering, etc.
As was said, many engines from other cars can be installed on the VAZ-2121, but the most preferable are
: XUD9TE, D8A. 1.9 l, 90 hp, fits perfectly into the Niva, has 190 Nm at 2200 rpm, spins up to 4400 rpm, weighs a little more than 120 kilograms, will need heating of diesel fuel for the winter.
The second contender is an import diesel turbocharged FIAT-CMD with a volume of 1.93 liters. and 90 hp, the cost of a new engine ranges from 280,000 to 297,000 rubles, but this is not profitable and it is better to buy a used one.
Read
Another option can be used with BMW 1.6-1.8 liters; diesel is even much better.
Possible from a Mercedes 1.8 liter
. Many people have 2121 on their vase
engine
from Fiat Ducato 2.3 liters, however, this option is not the most budget-friendly and not the most powerful; the previous options are better suited for the Niva.
To finally tune the Niva, you can install a turbine, turbocharged Nivas, an incredible picture. However, the installed turbine can have a bad effect on the transfer case and it simply won’t hold up.
KEY-DOP
Installing a turbine on a Niva costs 35,000-50,000 rubles. It should also be remembered that the standard engine
Niva copes with the turbine, but its power is not enough; you can try to play it, but most often without success.
Basically, the work of the turbine is that, due to the exhaust gases, more friction is acquired, it brings a sensitive gain in horsepower and torque
.
Regarding driver safety
sitting in a VAZ 2121 car with replaced engines, we can say that there is a threat to him. In general, the Niva is a reliable car created according to Soviet GOST. However, by replacing the engine with a more powerful one, as stated, more than 120 hp, the car may simply fall apart on the road.
In general, VAZ- 2121
not a bad car, capable of conquering various roads and obstacles. As time shows, the modern automotive industry has not changed much. Replacing the engine with a Niva from a foreign car, and it will not be inferior even to modern SUVs! After all, it’s funny to see when an old, Soviet, shabby car overtakes a modern foreign car.

What kind of diesel engine can be installed on Niva
Diesel for Niva: solving problems of self-installation
Gasoline engine on Chevrolet Niva
Not only imported engines are suitable for the Niva. Domestic production is also quite suitable. For example, a sixteen-valve power unit from VAZ can be easily installed without modification. It has lower fuel consumption than diesel engines and more power.
Car owners of such an engine are advised to change the camshafts for traction. There is no need to replace the gearbox. Engines from foreign cars require improvement. The next block will show which gasoline power units are suitable for swapping a Niva engine.
With modification
Niva is suitable for an engine from a BMW M42, M43 or Toyota, but gasoline. You will need to buy some parts for the swap, but changing the engine to one of these will give results that will surprise you. The car will become more maneuverable and will respond better to the accelerator pedal.
The fuel consumption of these power units is low. Therefore, you won’t have to spend money on them if you only follow the technical inspection rules and visit service centers on time.
No modifications
Many engines that are suitable without modifications for the Chevrolet Niva do not differ from the power unit that left the factory with the vehicle. Therefore, experienced mechanics advise installing an additional turbine if you want to increase engine power. The choice of gasoline engines is much higher than that of diesel engines.
A budget engine that will successfully fit into a Chevrolet Niva is Toyota’s 3S. There is no need to make major changes when installing this power unit. You can install a transmission from this car and a transfer case. Then Niva will become more powerful.
Attention! When swapping a power unit, do not forget that the controllability of the car changes along with the engine. For example, if a more powerful motor is installed, then controllability deteriorates somewhat.
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.
- There are options from the Japanese concern Toyota - 3C and 3CT. You won't have to change the transmission, but you'll have to tinker with the fastenings. Another acceptable option with modifications is 2JZ. It will be necessary to install an automatic transmission and update almost all parts of the exhaust system and engine compartment, since the model is too powerful for the standard Niva design.
- Engines from BMW models M42-M43. To install, you will have to use a few tricks and buy a few additional parts, but the final effect will please many car enthusiasts.
Chip tuning
This method is the cheapest since the engine does not undergo any technical changes. The work of chip tuning comes down to changing and adjusting the software in the ECU, which regulates work processes in the heating system. Using this type of tuning, power increases by 15%. Despite the fact that this method is the cheapest and makes it unnecessary to perform any manipulations with the power unit, it has its drawback: increasing power causes an increase in loads, thereby reducing its service life.
Tips for improving the “native” engine
In addition to the above changes, you can try using lightweight valves and guide bushings for them. This will reduce the resistance to the suction flow of the working mixture into the cylinders, improving filling capacity increases the power performance of the engine. It can be recommended to lighten the mass of the flywheel (see the article “Pros and cons of a lightweight flywheel”). It has areas where excess metal can be removed. Reducing its inertial mass saves power to overcome the moment of inertia of the engine.
You can also improve the performance of the engine by installing a tuning camshaft and a split gear in the timing drive. The installation of a so-called zero-resistance air filter will help improve the filling of the working cylinders with the air-fuel mixture. To improve the removal of exhaust gases, direct-flow exhaust systems are used. There are tuning engines with Solex carburetors, which have increased flow sections of the diffusers of the primary and secondary chambers. It is also advisable to replace the ignition system with a more modern, electronic contactless one.
