What engine can be installed on the VAZ 2107
Content
Connoisseurs of the history of the domestic automotive industry know that the VAZ 2107 is a luxury version of the old VAZ 2105 model. The essential difference between the GXNUMX and the prototype is its engine, which is more powerful and reliable. The engine has undergone modifications and adjustments more than once, and the model of different generations was equipped with different types of motors.
Is it possible to put another engine on the VAZ 2107
In its entire history, 2107 different versions of engine units were installed on the VAZ 14 - both carburetor and injection (of a new type). The displacement of the engines varied from 1.3 liters to 1.7 liters, while the power characteristics varied from 66 to 140 horsepower.
That is, one of 2107 standard engines can be installed on any VAZ 14 today - each of them has its own specific properties. Therefore, the car owner can put a new engine for his personal needs - more sporty, runabout, draft, etc.
Technical characteristics of the standard motor "seven"
However, the main engine for the VAZ 2107 is considered to be a 1.5-liter engine with a capacity of 71 horsepower - it was this power unit that was installed on the overwhelming number of "sevens".

Engines from other VAZ models
Motors from other models can be installed on the "seven" without any major alterations of fasteners. So, the easiest way to "get up" is the motors from the 14th series VAZ. The only caveat is that it is not easy to find a unit of acceptable quality from a VAZ 2114; it will also be difficult to find components for repair and maintenance in car dealerships.
However, before changing your regular engine to a motor from another model, you should think about the advisability of such a replacement. First of all, you need to take into account at least three factors:
- Compliance of the new unit with the old one in terms of weight and dimensions.
- Availability of possibilities for connecting all lines to the new motor.
- Potential compatibility of the motor with other systems and assemblies in the car.
Only if these three factors are observed, replacing the engine with a VAZ 2107 can be considered advisable and problem-free: in all other cases, a lot of work will be required, which, by the way, will not guarantee the proper functioning of the new power unit.

Motor from "Lada Niva"
The power unit from "Niva" practically without modifications is included in the engine seat on the VAZ 2107 - it has the same dimensions and shapes. The volume of a typical Niva engine varies from 1.6 to 1.7 liters, which makes it possible to develop power from 73 to 83 horsepower.
It makes sense to install a more powerful engine so that the "seven" felt the pull and strength that all "Lada 4x4" have. In this case, you can choose the most convenient type of motor performance:
- carburetor;
- injection.
In addition, the power unit from "Niva" is more modern - for example, it contains such progressive mechanisms as hydraulic valve lifters and a hydraulic chain tensioner. In this regard, the "seven" becomes not only "faster", but also much quieter during operation. It is important that the Niva engine is also less demanding in terms of adjustments and maintenance.
when he messed with this question, he began to find out, but then he abandoned such an undertaking. there are a lot, but it is difficult to find imported engines, especially assembled with a mounted and live controller and electrics. It's easier and cheaper to buy Nivovsky 1.8. I heard they refused to install Opel engines on the shnives, there will be no more of them, especially since there was also a box of its own.
Motor from "Lada Priora"
Engines from Lada Priora are often installed on the VAZ 2107. It should be noted that the new engines significantly optimize the work of the "seven" due to the fact that they have a volume of 1.6 liters and a power of 80 to 106 horsepower.
However, it should be borne in mind that engines from the Priora are only injection engines, and therefore may not be installed on every model of the Seven (or a significant revision of the entire engine compartment will be required).
The only drawback of using a modernized engine is that the installation of the unit will take time: it will be necessary to adjust the mountings to the size of the motor, as well as to make changes in the fuel supply systems, cooling and exhaust systems. "Priorovsky" engine has slightly different shapes than the engine from the "seven", but it easily fits into the seat under the hood. Nevertheless, all other nuances of installation and connection will have to be configured independently.

16-valve engine: is it worth it
Only 2107-valve engines were initially installed on the VAZ 8. Of course, the idea of putting a more productive 16-valve engine does not leave the minds of some "seven-drivers". However, does it make sense to change the power unit, and at the same time significantly modify the entire engine operation system?
16 valve classics are no longer a secret, they put everything all over the country. And why ? Because the injector ... uuuu ... type knocks ... uuuu ... . Everywhere there are only pluses, wai wai wai. Great ! Now I want it too! But damn it! Kotany is sewn on the soap, 16 rides better unambiguously. But it requires even more attention than a carbureted engine ... all sorts of expensive sensors ... ugh!
Therefore, if the driver is not ready for additional expenses and constant maintenance of a 16-valve motor in service centers, it is better to do without installing such a unit.
Rotary engine
Rotary motors for domestic cars can be considered the most suitable option. Any rotary engine has three important driving advantages:
- High engine speed (up to 8 thousand rpm in the mode of continuous long trip without any damage to the unit components).
- Smooth torque curve (no strong sensory dips in any driving mode).
- Economical fuel consumption.
On the "seven" you can install a rotary power unit RPD 413i, which has a volume of 1.3 liters and a capacity of up to 245 horsepower. The motor, with all its power, has a significant disadvantage - only 70-75 thousand kilometers before the need for major repairs.
Engines from foreign cars
Connoisseurs of foreign engines can easily install engines from the Fiat or Nissan models on the VAZ 2107. These units are considered akin to our domestic models, since it was the design of the Fiat car in the early 1970s that formed the basis for the development of all VAZs and Nisans.
Mounting a motor from a foreign car will require minimal alterations, while the car's behavior on the road will immediately become more optimized.
Roughly speaking, on the VAZ 2107, with a strong desire, you can put almost any power unit that fits in size. The only question is the expediency of replacing and spending the owner on the purchase of a motor and components for it. Not always the installation of a more powerful and economical engine can be considered the best equipment option: all categories of motors have their advantages and disadvantages, which are best known in advance.
