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.
Practical advice for installing a diesel engine
When deciding to install it yourself, you should pay attention to the following experience. Among the possible units that the designers of both the classic car and the Chevrolet Niva considered was the Peugeot engine with the index XUD-9SD
Not the most powerful unit (from 69 to 75 hp) is highly reliable.
When planning such tuning, you need to be prepared to make some modifications:
- Replace the gearbox. Among the options, a box from Fiat Polnes was offered, as it would work with such an engine. But it won’t be easy to find a unit from a car that is now rare.
- Clutch mechanism. When searching for a box, they immediately select a clutch mechanism, which must ensure transmission of rotation and match in size.
- Engine support points. When installing on the Niva, the front engine mounts required modifications.
- Pallet shape. Taking into account the dense layout of the Niva’s engine compartment, the pallet requires an original shape, and was often made individually.
- Exhaust system. Minimal modifications to the exhaust piping are required.
The serial Niva with this engine was produced until 2009 and was mainly exported. With a certain amount of luck, the car can still be found in advertisements for sale. A special feature of the car is its low dynamics. The car reaches the first hundred in only 25 seconds.
When carrying out independent modernization, do not forget about one more aspect. Replacing the engine with a non-similar version will require technical expertise. In practice, it will be possible to undergo such a procedure, but it will require a certain investment of time, money and nerves. Only after this you have the right to count on hassle-free registration of your car with the traffic police. Perhaps we should wait for the car to appear in a diesel version when the new generation comes out.

What kind of diesel engine can be installed on Niva
Diesel for Niva: solving problems of self-installation
Passenger cars and SUVs with diesel engines are very popular abroad. For us, the idea of equipping a car with such an engine did not take root for a long time. Only not so long ago UAZ all-terrain vehicles with such an engine began to arrive on the market.
Nevertheless, there were attempts to make a jeep with a diesel engine. One example of such a car was the diesel Niva
.
This VAZ Niva 2121
was exported and had an index of 21215.
Equipping a car with a diesel unit has a number of positive qualities. These engines are significantly more economical than gasoline-powered units and are less demanding on fuel quality. They have excellent traction characteristics at low engine speeds. The service life of a diesel engine is not easy, which allows it to be used longer without undergoing extensive repairs.
The main drawback of these engines is the complexity and high cost of repairing the fuel accounting system, since a number of units use precision-machined parts.
VAZ 21214 engine modifications and their differences
| Motor modification | Availability of power steering | An exhaust manifold | EURO environmental class |
| 21214-41 | welded from stainless steel become | 3 | |
| 21214-34 | _ | cast iron | |
| 21214-33 | |||
| 21214-32* | |||
| 21214-31 | welded from stainless steel become | 4 | |
| 21214-30 | — |
*21214-32 – has fuel pipes with quick connectors, a flywheel for the clutch of 215 mm (200 mm on other models).
The geometry of the cylinder block 21214 and 21213 is the same. There are no liners in the cylinders. Due to the use of an ejector, the configuration of the front engine cover has been changed to accommodate the installation of a crankshaft position sensor. To mount the power steering, a hole is made on the block for installing a bracket; in addition, there is a threaded hole for installing a knock sensor, as well as threaded holes with studs for mounting the ignition module bracket.
The ShPG came from 21213. Crankshaft 21213-1005015 sets the piston stroke to 80mm. The crankshaft pulley is distinguished by the presence of teeth along the outer diameter for the operation of the crankshaft position sensor. The latest internal combustion engine models are equipped with a damping pulley (21214-1005058-10). The presence of a damper made it possible to reduce the load on the crankshaft to prevent cutting of the key, and also make the operation less noisy.
Cylinder head 21214-1003011-30 (36) was modified from the head from 21213. For modification, it was necessary to introduce holes for installing a phase sensor and studs for mounting the intake receiver. To install hydraulic compensators, bosses are cast in the head and have threaded holes in them. With the introduction of hydraulic thermal gap compensators, adjusting bolts were eliminated from the head design.
Oil under pressure is supplied to the hydraulic compensators through separate pipes. There are two types of heads: Russian 21214-1003015 and Canadian 21214-1003015-30. The differences between the heads are as follows: in the first, the diameter of the threads in the holes for hydraulic compensators is M18/1.5, the wells for hydraulic compensators do not have drainage holes;
the second ones have M24x1.5 holes, and the wells have drainage holes (the markings are made in the casting). Interchangeability of heads, as well as hydraulic supports of old and new designs, is not possible. A new oil rail 21214-1007180-30 made of stainless steel is used, supplying oil to the hydraulic compensators. Interchangeability with ramp 21214-1007180 is maintained.

Valve levers 21214-1007116-30, in contrast to the previous 2101-1007116, have a smaller radius (11 mm) of the platform support interacting with the camshaft cam, as well as an additional groove on the side of the hydraulic compensator. Both lever options are interchangeable.
In the timing camshaft drive, instead of a double-row chain, a single-row chain 21214-1006040-03 is used on rollers and bushings. Single-row sprockets for the chain are taken from the 2123 engine. The oil pump sprocket has the number of teeth reduced to 30 to increase the performance of the oil pump and improve the operation of the hydraulic chain tensioner and hydraulic compensators.
The camshaft 21214-1006010 is original with a modified cam profile and can be interchanged with the shaft from 21213.
The 80 amp generator is the same as the 2112, with a slight difference in the diameter of the pulley 80 mm for the drive belt 2107-1308020 (944 mm).
The exhaust manifold can be made of cast iron or stainless steel. The cast iron manifold is made by casting. The stainless steel manifold version has a welded design. A welded manifold is lighter and heats up quickly, which is good for the operation of the catalyst located in the manifold. In addition, an oxygen sensor is installed in the exhaust manifold.
The intake manifold and fuel rail (2123-1144010-11) were borrowed from the 2123 engine. The injectors of the fuel injection system are SIEMENS VAZ 20734 (yellow), injectors (0280 158 110) were installed on early engines.
Ignition module from engine 2112.
Electronic control is carried out by the BOSCH MP 7.9.7 ECU. or JANUARY 7.2 depending on the year of manufacture and modification of the internal combustion engine.
The cooling system began to be assembled using gaskets with an elastic polymer bead, which improved the tightness of the system. The water pump (pump) includes an oil seal (cuff) that is more resistant to wear and loss of properties.
What engine can be installed on Niva 2121
We install the engine on the Niva from a foreign car. It's worth it
Why do some owners install a foreign car engine on the Niva? Old Russian cars like the VAZ-2121 Niva, VAZ-2107, VAZ-2108 at this time seem at least not profitable, and at most not at all capable.
At the moment, you won’t see an entrepreneur driving a Veil, although not long ago it was one of the most massive cars; its cross-country ability was unattainable for the EU and the USA. But not now…
What problems can installing a foreign car engine on a Niva help solve? If you need to think about what, what method to do so that Niva
has become profitable and convenient for the modern world, then change your heart! In fact, it’s natural to put it
Almost any engine removed from a foreign car.
However, the engine must meet several requirements
: to fit inside the hood of the car so as not to cut off additional parts (this can have a bad effect later_. And most importantly, the engine power should not greatly exceed the power of its predecessor. After all, if you install an engine that is too powerful, the car’s design simply won’t withstand it; cars of that time were not created for power and speed, but for reliability.
Read
The new foreign car can barely withstand a head-on blow with the Niva, and VAZ has a great chance of winning. But Niva, when making a sharp turn at a speed of 150 km. at an hour it will most likely fly into a ditch, and the foreign car will continue on its way.
KEY-DOP
Of course, the engine must have more serious characteristics compared to its predecessor, because without this the entire replacement will be pointless.
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?
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.
Calculation for a foreign internal combustion engine
Numerous experiments with the Niva Chevrolet diesel engine have shown that a foreign car engine of similar volume and power (no more than 120 hp) is significantly superior to a standard gasoline engine.
The installation of domestic Barnaul diesel and foreign aspirated engines, on the contrary, did not reveal any serious advantages. The car turned out to be sluggish, the maximum speed and elasticity dropped, and the characteristic tractor sound of a running diesel engine was annoying. Therefore, the optimal solution is to install modern turbocharged engines, which eliminates most of these disadvantages.
The ideal option for a new “heart” for the Chevrolet Niva is considered to be engines from the XUD SD line from Peugeot. These motors are well known from such models as the Peugeot Partner, 307 and other cars of the concern. The engine life exceeds 500 thousand km with timely maintenance.
The advantage of this diesel engine is that it is installed on standard mounts under the hood and docked with a VAZ gearbox, which greatly simplifies the amount of alterations. In some cases, a Fiat Polonez gearbox with an original clutch is installed with the same engine. This hybrid Niva consumes only 7.5 liters of fuel per 100 km, and the torque of 195 Nm is enough for off-road and comfortable driving on the highway.
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.

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.
What is LADA 4×4
LADA 4×4 is an all-wheel drive vehicle with an engine capacity of 1.7 liters and a power of 83 horsepower.
The maximum speed of the domestic “tank” is 142 km/h. It can easily pass almost any stone under the bottom thanks to its ground clearance of 20 centimeters. The trunk volume can reach 585 liters. Average fuel consumption is about 10 liters. Many are attracted by the price of the car, because you can buy it for 400-500 thousand rubles. Is it a lot or a little - there is no objective assessment, since everyone gives their own. But is the all-wheel drive Niva worth even this money? Probably not, since there are many budget SUVs that are in many ways superior to the domestic 4x4.
Let's look at them in more detail.
Features of installing a diesel engine on a VAZ 2121
If the manufacturer does not provide the opportunity to buy a Lada 4×4 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 Lada 4x4) 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 are suitable for VAZ 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 Lada 4×4 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.
From a foreign car
Do you want to install the engine in the Niva without modifications? Then try another diesel from Pegout XUD9SD with a volume of 1.9. The engine is very reliable and torquey, and what’s most interesting is that it fits perfectly into the Niva using almost all fastenings.
After this modification, the Niva will become very dynamic, and it will definitely not let you down off-road. There will be no problems with spare parts.
In conclusion, I would like to say that absolutely any engine can be installed in any car. The most important thing is desire, without it you can’t go anywhere. And love your car.
