Tuning

It is noteworthy that tuning a VAZ engine, as well as its repair, is possible for any owner who has at least a little knowledge of the technical characteristics of VAZ engines and has encountered repairs or overhauls of the engine.

But here the choice is between efficiency and power. Knowledge of which engines bend the valves is also important. The approaches to them are very complex.

The most common is tuning the VAZ engine, which increases the output parameters. For example, installing a new camshaft with an adjustable pulley, replacing connecting rods and pistons to increase displacement.

Well, in order for the power to be realized into the dynamic data of the car, the gearbox ratios are changed. This is the most budget-friendly VAZ engine tuning without any outside interference in the auxiliary units, despite the fact that this same tuning can be much more extensive.

It is worth remembering that any increase in power leads to additional fuel consumption and reduces the life of the unit; accordingly, it requires increased attention to maintenance and replacement of consumables. Therefore, the issue of tuning must be approached painstakingly and it is advisable that a person well versed in this take part in this.

What engines was equipped with the VAZ 2107

"Seven" was produced for a very long time - from 1972 to 2012. Of course, during this period, the vehicle’s configurations and equipment changed and were modernized. But initially (in the 1970s) the VAZ 2107 was equipped with only two types of engines:

From its predecessor 2103 - a 1.5 liter engine.
From 2106 - 1.6 liter engine.

On some models, more compact 1.2 and 1.3 liters were also installed, but such cars were not widely sold, so we will not talk about them. The most traditional for the VAZ 2107 is a 1.5 liter carburetor engine. Only later models began to be equipped with 1.5 and 1.7 liter injection engines.

Moreover, a number of rear-wheel drive VAZ 2107 exhibits were equipped with front-wheel drive engines, but the designers immediately abandoned such an idea - it was too labor-intensive and unjustified.

Reliability, weaknesses, maintainability

Reliability

Due to the short service life, there is no specific data on engine reliability yet. But according to the manufacturer’s forecasts, the VAZ-11182 is considered the most successful option among all VAZ 8-valve engines. Accordingly, the new motor is positioned as quite reliable.

The development of new, “stickless” pistons has significantly raised the spirits of car owners of this internal combustion engine. Gone are the nightmares about the possible consequences of a broken timing belt - bending of valves, destruction of the piston and expensive repairs.

The bearings and connecting rods are copied from the VAZ-21179 engine. The crankshaft is updated, but the connecting rod journal is identical to the crankshaft journal of the same 1.8-liter VAZ-21179. Here the priority was to reduce mechanical friction losses and increase reliability.

It is clear that the maximum loads of the 122-horsepower and 90-horsepower engines differ significantly from each other. Thus, the VAZ-11182 crankshaft contains an additional safety margin, which increases its reliability.

It is appropriate to note that more than 20 items of parts and components have been replaced on the engine. It is characteristic of the VAZ-11182 that all new changes in the mechanical part were made not by designed parts, but by previously used parts and assembly units that had already proven themselves in practice.

For example, valve stem seals are taken from the H4M engine (developed by Nissan, produced by AvtoVAZ). From the same engine, valve tappets and crackers are used.

The first reviews, or rather, discussions about the engine, appeared on the forums. So, StAndr writes: “... the pistons have become heavy with a good compression distance, the connecting rods are now centered on the crankshaft cheeks, and not on the piston bosses. The block is cast iron, not aluminum, like on foreign cars - it holds the geometry well. There are oil nozzles. The torque is not bad - 143 Nm, and from 1000 rpm 80% of the torque is available, i.e. 114 -115 Nm."

The changes made to the internal combustion engine of the VAZ-11182 allow us to hope that the engine will be highly reliable.

Weak spots

The engine has not yet had time to prove itself in operation, so there is no information about its weak points. But on the forums you can find scant data on this issue.

For example, one of the owners of the VAZ-11182, in all likelihood, had to deal with disassembling the engine. In his review, he noted that there was rough surface milling on the plane of the cylinder block. As a result, problems arose with oil and coolant leaking through the head gasket.

But such reports are rare, and it is too early to judge whether the error in block processing is a weak point.

Sometimes the engine shakes at idle speed. Replacing the spark plugs and adjusting the ignition mechanism eliminates this problem.

Some engines have increased oil consumption. Usually this problem occurs around 80-100 thousand kilometers. Oil intake can be about 900 grams. per 1000 km. The true reason for this phenomenon has not been clarified, but it is believed that the design feature of the CPG is to blame.

Maintainability

The maintainability of the unit is good. But it should be noted that the repair process itself is complex. You can't do this without experience and special tools. Forum member 46B writes: “...now you can’t adjust the valves in the garage, you have to disassemble half the engine, and the price of pushers is from 1,500 rubles. for 1 piece."

In general, there are no problems with finding spare parts. The only trouble is that you can run into a fake. The Chinese manufacturer is especially famous for counterfeit products.

Therefore, when restoring an engine, it is recommended to use only original components and parts.

The modern VAZ-11182 engine is a completely reliable and economical engine, but only if it is handled accordingly.

Maintenance

Reviews from car owners about the VAZ 11182 engine indicate that timely maintenance is required to increase the life of the power unit. Once every 15 thousand kilometers it is necessary to change the engine oil, but with an engine capacity of 4.5 liters, about 4.1 liters will be required to change it.

The declared resource of the timing belt is about 160 thousand kilometers, but it is worth contacting a service center to replace it after 100 thousand kilometers. It is clear that almost no one does this, since the clan is not oppressed, but not everyone wants trouble to meet them on the road.

Motor 2101 “Kopeyka”

It’s no secret that the first “Kopeyka” is a prototype of the Italian FIAT 124.

Accordingly, the first of the VAZ engines was initially only a modification of its predecessor, a kind of tuning of the VAZ engine.

The characteristics of VAZ engines have been changed:

Thanks to the transfer of the camshaft from the lower to the upper part, an increase in the cylinder diameter by 3 mm, and a decrease in the piston stroke by 5.5 mm, the unit became more throttle response due to its transformation into a “short-stroke” one. The speed picked up faster, and throttle response began to be felt more strongly with sudden changes in the accelerator position.
The only drawback of the engine at that time, which received the marking 2101, was the increase in noise.
4 years later, after the modification of “Kopeyka” 21011, a modernized VAZ engine of the same name appeared with markings identical to the model number. It began to differ from its recent ancestor in the following indicators: the VAZ engine displacement increased from 1200 to 1300 cm3, the cylinder diameter increased by another 3 mm, and the power increased by 3 “horses”. This VAZ engine was installed on both 01 series models and subsequent 2102 models.
Carburetors for these engines were produced in 3 series until 1978, and later the Ozone 2105 appeared, which acquired an autonomous idle system, slightly changing the technical characteristics of the VAZ engine. These carburetors became much more practical, the car started easier in cold weather, and the quality of the fuel was less reflected in idling and sharp pressure on the accelerator.

Further tuning of the VAZ engine consisted of strengthening the transmission, which Italian engineers liked, and later they began to use Soviet modifications on their units.

Later, exports began to spread, and for the first time a rotary engine in a VAZ appeared on cars sent to neighboring countries.

This was the first successful experiment, but due to the difficulty of repairing such a unit and the virtual lack of spare parts, over time these types of motors became unpopular. Although analysts predicted a good future for units of this type, it was only necessary to properly establish the spare parts market.

So which one is better?

Having familiarized ourselves with the main characteristics of our contenders, we can now safely sum up the overall results and name the winner. If you approach the question from a rational point of view, the answer to the question: “which VAZ engine is the best?” seems more than obvious - the last in the line, that is, the newest and most modified, and indeed, the VAZ 21127 engine, after all its modifications, looks like a clear favorite for the title of best, because for all its shortcomings, these are the same problems as in 21126 In case of timing belt failure and expensive maintenance, it offers very cool performance, especially for those who like to ride with the breeze. VAZ 21126 and 21127 are like brothers, however, the “twenty-seventh” is younger, but stronger, and the “twenty-sixth” is older and more confident, so to speak, that is, more significant in terms of the audience reached. Therefore, we will not even try to compare these two engines with each other, but will combine their capabilities against a common competitor - the VAZ 21116. Here we will formulate the question somewhat differently: “which engine is better, eight valve or sixteen valve?”

As an answer and, accordingly, to determine the winner, we present the following information: the main power records demonstrated by VAZ engines were achieved precisely with the help of units with 16 valves, and most importantly, when choosing a car with a 16-valve power unit, positive the owner receives more aspects than negative ones. An increase in the used volume of the fuel-air mixture, which enters the cylinders, also affects the increase in power, which is confirmed by the technical descriptions of each of the engines. In addition, changing the shape of the combustion chamber in the 16-valve engine allows it to show higher knock resistance, which is very important given the quality of the fuel that is sold at gas stations. It should also be said that in engines with 16 valves the cooling system works better, which helps to increase the reliability of the power unit. What the 8-valve unit benefits from is cheaper maintenance and, in fact, availability, since it costs less than its competitors. At one time, 8-valve power units were optimal for operation in our conditions, however, progress has made positive adjustments, allowing the engines to be modernized.

Description

The new VAZ-11182 engine was presented to the general public quite recently, in January 2022. He received his first registration for Lada Largus FL.

Later it became the basic modification for Largus van and station wagon models. In the spring, in May of the same year, VAZ-11182 began to be installed on the Lada Granta.

The engine is a four-cylinder in-line naturally aspirated petrol with a volume of 1.6 liters and a power of 90 hp. s and a torque of 143 Nm.

VAZ-11182

The main changes in comparison with its predecessor can be roughly divided into three groups:

crankshaft;
ShPG;
Timing belt

In addition to those listed, many more engine components were modified.

The cylinder block remained traditionally cast iron and did not receive any significant changes.

cylinder head. Here the modernization was extensive. In the head, changes have been made to the cooling jacket, intake and exhaust channels, and the combustion chamber has been optimized. If previously the combustion chamber was formed only by the cylinder head design, then on the VAZ-11182 it has a continuation in the piston bottom.

As a result, the conditions for mixing air with fuel improved, which led to an increase in the compression ratio and a change in ignition timing.

Aluminum pistons with three rings. Two of them are compression, one is oil scraper. It should be noted that the oil scraper ring has become three-component. The result of this modification is that oil waste is halved. In addition, the new piston design made it possible to expand the flame zone.

The rings began to operate at more acceptable temperature conditions. And one last thing. There is no contact between the piston and the valves in the event of a broken timing belt. In this case, the engine simply stalls.

The engine received a new camshaft. It became 0.5 kg lighter. In addition to weight, the geometry of the cams has been changed. The working part is now only 11 mm versus 15.3 on the old one.

The backs of the cams have been reduced to 6 mm (previously they were 17.7). The result of the modification was an improved fit of the valve in the seat, which reduced the noise level of the timing belt.

Appearance of the new camshaft

The valve design has been changed. The diameter of the rod became 5 mm. The thickness of the valve seats has also been reduced from 9 to 6 mm.

A new design of valve tappets has been introduced. Whether such a development will become more useful and durable is still an open question. The essence of the problem is that previously the pusher used two springs and an adjusting washer.

On the VAZ-11182 only one spring is left. There is no adjusting washer. When adjusting the thermal clearance of the valves, the pusher will have to be replaced. On the cost side, this is not a very profitable solution - the washers cost pennies.

But there is also a positive aspect. Now thermal clearances are subject to adjustment after 90 thousand km of vehicle mileage, and not after 45, as on the VAZ-11189.

The crankshaft has undergone significant changes. Firstly, the number of counterweights has been halved. There are only four of them. Secondly, the width and diameter of the crankpins of the shaft have been significantly reduced.

Updated crankshaft

Additional good news is that the oil supply circuit to the crankshaft liners has been optimized.

The engine is not demanding on the quality of fuel and lubricants. It works equally smoothly on AI-92 gasoline and semi-synthetic oil.

The graph clearly shows the result of introducing all the new products into the VAZ-11182 power unit.

Conclusion

Therefore, to summarize and name the best VAZ engine, we give preference to the 21127 power unit, which in all respects is ahead of its competitors in this impromptu rating, but with one amendment, since its owners should be prepared for significant financial costs in the event of unexpected malfunctions . This top of the best is our subjective opinion and you may well either support it or disagree with our opinion. You can always present your arguments on this matter with reviews in the comments on the forum, share interesting photos and videos, and also offer your own options, which, in your opinion, are worthy of the title of the best VAZ engine.

Valve adjustment will become more difficult

Previously, adjusting valves required only removing the valve cover, some simple skill, and a set of shims that many owners had accumulated over decades. Now, to adjust the gaps, you will have to raise the camshaft, measure the cups (pushers) and buy new ones for about a thousand apiece. Therefore, it is more profitable to contact the service. Moreover, the gaps will now have to be adjusted less frequently - only every 90,000 km.

A one-piece valve lifter instead of the previous shim design is a step forward. But this step will complicate maintenance for the consumer at high mileage.
