Which carburetor is better to put on VAZ-2106: advice of specialists

Today, on the roads, you can often find cars, whose age is 20, or even 30 years. In general, these are classic models of VAZ. Owners of these old cars in every possible way support their life and pursue the optimal characteristics. The owners of the old "Zhiguli" want to increase the dynamics of the car and reduce fuel consumption. It can be done, but it all depends on the carburetor. Let's consider what carburetor is better to put on the VAZ-2106 to get the result. This task is completely feasible, while the driver can perform the replacement of the device and adjust it independently. If you read the reviews of drivers who have replaced the regular carburetor, the effect is quite palpable.

A Brief History of Carburettors for VAZ

On the first classic models of the VAZ, which was an improved Italian "Fiat", the power supply system was paired with motors installed by the Dmitrovsky auto-aggregate plant. For the production of these carburetors, a license was acquired from the French firm Weber. These mechanisms were assigned the DAAZ-2106 index for the VAZ "Six" model. Until now, such carburetors are popularly known as "DAAZ" and "Webery". Many car owners are now actively exploiting them. The use of these mechanisms gives good dynamic characteristics. These carburetors have a simple design without superfluous design features. But "Webery" have one quite significant minus - it's huge appetites. These models have not been produced for a long time, because together with the VAZ-2105 model all the other Zhiguli were completed with Ozone products. Below we will talk about it in more detail.

"Ozone"

The carburetor "Ozone" on VAZ-2106 is a completely domestic development of Dmitrov engineers. It differs significantly from the French mechanisms for both the constructive and the performance characteristics. This name "Ozone" (carburetor) was not just received - at that time it was considered the most environmentally friendly. The owners are positive about these devices. But with them sometimes there are various problems. For VAZ-2106, its price is from four thousand rubles.

Ozone and its problems

Sometimes the pneumatic actuator of the flapper on the secondary chamber refuses to operate normally. Also, there are troubles with the worn out diaphragm in the economizer system of forced idling. If the mechanism for some reason got dirt or disturbances, the second camera may not open at all or open, but with a serious delay. This leads to a significant decrease in dynamics. The power is lost, the maximum speed of the car decreases, the engine is unstable at high and medium revs. Despite all this, the carburettor DAAZ-1107010 "Ozone" gives good dynamic characteristics with a fuel consumption of about seven liters per 100 kilometers. Naturally, the device must be constantly monitored and serviced by it. In order not to pollute the internal chambers, it is recommended to periodically clean them. A special carburetor cleaner is used. средство продается в аэрозольных баллончиках. This chemical is sold in aerosol cans.

Solex

These mechanisms are no less popular. Particularly popular is DAAZ-21053. It is also manufactured under license. This carburetor has good dynamic characteristics and at the same time is economical. This is a good solution if you need a carburetor for the "Six". By design, "Solex" fundamentally differs from all previous devices from the Dmitrovsky auto-aggregate plant. Solex is equipped with a fuel return system. With this solution, gasoline can get back into the gas tank of the car. By using the fuel return system, it is possible to save up to 400-800 grams of fuel for every hundred kilometers. Some versions of Solex can be supplemented with auxiliary electronic systems. Among them - an idling system with the possibility of adjustments by means of an electric valve. Also found on export models. In the CIS countries, the model with an electric idle valve was widely used . In operation, this two-chamber carburetor was quite difficult. The channels are made narrow and often clogged. If the device is not serviced, then the idling system first started to jam, and then all the other nodes. On fuel consumption "Solex" on VAZ-2106 consumed from 6 to 10 liters when driving in a quiet mode. According to the dynamic characteristics, the unit is second only to the early "Weber". If timely to do preventive repair of the carburetor, Solex will not cause any special problems.

How to choose a carburetor and what to install on the VAZ-2106?

Lovers make modifications to the classic models from AvtoVAZ and just owners who want to improve the performance of the car, most often choose Solex. Use the DAAZ-21083 model. Installation of them on classical models is impossible without significant modifications. Thinking about which carburetor is better to put on the VAZ-2106, it is necessary to take into account the volume of the motor. For units of 1.3 liters, the DAAZ-2018 variant is perfect. For engines with a volume of 1.6 liters, the best choice is DAAZ-21083. The differences between these two models are in the diameter of the diffuser section, as well as in the dimensions of fuel and air jets. If you install this carburetor as it is, then at speeds close to 4 thousand, the air release rate can reach supersonic, which is not permissible. But it does not affect the overclocking. It is necessary to increase the diffusers on the first and second chamber, install other jets. After that, fuel consumption will be as at 21053, and the dynamics - better than 21073. For VAZ-2106 cars, the price of such a carburetor will be about five thousand rubles.

Features of the DAAZ-2108, -21083

For mounting any of these models on the "Classic" you need to prepare a new set of gaskets, hoses for the carburettor heating system, a tee to connect to the fuel system, a valve and traction to betray the accelerator. To get the maximum result from this procedure, it is desirable to replace the ignition. It is better to install a more technological, electronic. Contact ignition is the last century. The system is very unreliable and often causes operational problems. The installation of a non-contact electronic ignition is one of the most useful improvements for domestic VAZs, in particular for the "Six".

"Solex-21053"

This model has less problems and does not require serious tuning, since this carburetor is modernized for classic models. These units work well with 1.5 and 1.6 liter engines. This is an excellent choice for those who would like to get more dynamics from the car.

Other options

But do not think that this is all that is suitable for the "Classics". If you think about what carburetor is better to put on the VAZ-2106, then I remember "Solex-21073". It is designed for motors of 1.7 liters - from 21053 it is distinguished by large channels and enlarged jets.

After its installation, you can get even more dynamics, and fuel consumption at the same time will be 9-12 liters. And if the expense and rare preventive repair of the carburetor "Solex" does not frighten, then you can stop choosing it.

The result

Of course, this is far from all carburetor models that can be installed specifically on the VAZ-2106 and other classic "Lada". There is a mass of Chinese devices, as well as devices from European and American manufacturers. On sale there are both single- and double-chamber models. But they are distinguished by a high price and do not always guarantee a high dynamic performance and economy. You will receive only one of the two. Therefore, the question of which carburetor is better to put on the VAZ-2106, you can answer this: it is best to put a domestic device, one of the above. Reviews of motorists recommend to put "Ozone". He is one of those, which with a small fuel consumption gives the maximum dynamics for the car.
