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.

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.
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.
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.
Technical characteristics of engines on Niva
Since the domestic car has been so advertised, let's take a look at the technical characteristics of the Niva 2121 internal combustion engine. They are all recorded in the table.

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.
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.
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.
What do they do with the injectors?
They can also be somewhat modernized, and the first thing they may recommend to you is to reprogram the electronic control unit (see “Pros and cons of chip tuning”). Next, they resort to installing a compressor in the engine power supply system. Use model PK-23-1
, it develops a pressure of about 0.5 bar. Bosch 107 Volga injectors for it
.
You can also boost the engine with a turbine (again, see the article “Which is better, a turbine or a compressor”), but this is the most financially expensive method. We hope that our story provides an answer to the question of how to increase the power of a Chevrolet Niva engine, but whether it’s worth doing is up to you to decide. Often, the result of increasing engine power can be a decrease in its service life.
Pros and cons of the regular Niva compared to the Chevy Niva
Let us highlight the characteristic features relating to both the 21st Niva and subsequent models VAZ-21213 and VAZ-21214. We will not consider the Long Niva (VAZ-2131), pickup truck (VAZ-2329) and other modifications. So, let's start with the undeniable advantages of the regular Niva compared to the Shevik:
- Patency. Due to the short wheelbase, the 21st model has better geometric cross-country ability.
- Price . In the same condition, a regular Niva will be 1.5-2 times cheaper than a Shevik.
- Availability and low cost of spare parts. Especially for body parts.
- "Psychological passability". An ordinary Niva is not so scary to be scratched or slightly dented, unlike a Chevrolet.
- The best predisposition for off-road tuning.
Now let's list the disadvantages of the 21st Niva compared to the Chevrolet Niva:
- Low level of comfort. Noise, vibration, lack of power steering (on old Nivas), uncomfortable driving position.
- Outdated design. Although this is a controversial point, because the design of an ordinary Niva is recognizable all over the world, which cannot be said about the Shniva.
- Poor aerodynamics.
- Poor handling on the highway.
- Cramped interior. This includes an uncomfortable seating position in the back row and a small trunk.
Everything is clear with the advantages and disadvantages of the regular Niva compared to the Shevik. Let's move on to the Chevrolet Niva.
Let us list the main advantages of the Chevrolet Niva:
- Modern and quite successful design.
- Passive safety. Although its level is unacceptably low, it is still slightly higher than that of a regular Niva. Chevy cars of recent years are preferable in terms of safety.
- Relatively high level of driving comfort. Less vibration, less noise, comfortable driving position, power steering.
- Spacious salon. This also includes a comfortable back row, seating and a relatively spacious trunk.
- Good aerodynamics.
- More expensive than a regular Niva, both in purchase and in maintenance and repair.
- Poor cross-country ability due to the extended base and lower bumpers.
- An abundance of plastic, especially on new Sheviks. A controversial point, because plastic protects the body from minor damage (scratches, chips).
- Weak engine. The dynamics of Shevik are worse than those of a regular Niva.
- More mass. On marshy soils this is a minus, but in other cases it can be a plus (shallow mud, loose snow).
It is also worth paying attention to one more point - body rigidity. It seems that the three-door car should have it higher, but the Shevik has thicker side members, so not everything is so simple
