If you install a 54 throttle on a VAZ 2114, according to the manufacturers of such components, this makes it possible to increase the performance and power of the engine by reducing the air flow speed and better combustion of the fuel mixture. In reality, everything turns out to be not so rosy. The survey shows that only 12% of owners of the 14th VAZ saw positive changes in engine performance. 20% observed deterioration. What is the catch and how to properly install a wider throttle so that it really increases the performance of the car and improves its acceleration?
Does it make sense to install a 54mm throttle body?
Online stores often suggest installing 52, 54 or 56mm instead of the standard 46mm throttle body. The product description states that an enlarged throttle body (throttle body) reduces the air flow rate and increases the air flow rate of the intake system. The effect of the installation will be especially noticeable if the system uses a zero resistance filter. It is recommended to install a throttle with a diameter of 52 mm, because The diameter of the air inlet of the standard receiver is 53mm.
To install a throttle assembly of a different diameter, as a rule, nothing needs to be modified. The maximum that needs to be done is to trim the gasket a little (most often when installing a 56mm throttle body). After installation, many notice positive effects:
Throttle valve VAZ 2112 - flushing or upgrade?
To effectively regulate the amount of air that enters the combustion chambers of a gasoline engine, it is necessary to maintain the VAZ 2112 throttle valve in good condition. The mechanical regulator is located between the intake manifold on one side and the air-cleaning filter on the other. In fact, the quality of the formed fuel-air mixture directly depends on it.

“Fucking basin. "
Hi all! My name is Mikhail, now I’ll tell you a story about how I managed to exchange my two-wheeler for a 2010 Camry. It all started with the fact that I began to be wildly irritated by the breakdowns of the two-wheeler, it seemed like nothing serious was broken, but damn it, there were so many little things that really started to irritate me. This is where the idea arose that it was time to change the car to a foreign car. The choice fell on the melting Camry of the tenth years.
Yes, I had matured morally, but financially I just couldn’t handle it. I’ll say right away that I am against loans and taking a car, especially not a new one, on credit is unreasonable. My salary is 24k a month, so collecting 600-700 thousand is almost impossible for me. I started looking for different ways to make money on the Internet. You can’t imagine how many scams there are, what I haven’t tried: sports betting, network marketing, and even the volcano casino, where I successfully lost about 10 thousand ((The only direction in which it seemed to me that I could make money was currency trading on the stock exchange, they call it Forex. But when I started delving into it, I realized that it was very difficult for me. I continued to dig further and came across binary options. The essence is the same as in Forex, but it’s much easier to understand. I started reading forums, studying trading strategies. I tried it on a demo account, then opened a real account. To be honest, I didn’t manage to start earning money right away, until I understood all the mechanics of options, I lost about 3,000 rubles, but as it turned out, it was a precious experience. Now I earn 5-7 thousand rubles a day. I managed to get the car buy after half a year, but in my opinion this is a good result, and it’s not about the car, my life has changed, I naturally quit my job, I have more free time for myself and my family. You’ll laugh, but I work directly on the phone)) If If you want to change your life like me, then here’s what I advise you to do right now: 1. Register on the site 2. Practice on a Demo account (it’s free). 3. As soon as you get something on the Demo account, top up your REAL ACCOUNT and go to REAL MONEY! I also advise you to download the application to your phone, it’s much more convenient to work from your phone. Download here.
- The car becomes more playful.
- Problems with idle speed disappeared.
- The gas pedal becomes more responsive.
There are also disadvantages:
- Fuel consumption according to the BC increases and supposedly the readings are incorrect, the consumption has not changed.
Other owners of “ten” cars see the effect only at 16kl. motors.
In fact, the picture described above may be presented somewhat differently. The positive effect that many people notice when installing a larger diameter throttle body is due to the fact that the old throttle body needed cleaning and the engine was not working properly. After installing the new remote control, the motor begins to operate normally, which was presented as a “new breath”. In other words, the car would become more playful and the pedal more responsive after basic cleaning of the remote control.
What does a big throttle do?
The factory throttle valve in the VAZ 2114 has a diameter of 46 mm. This is the best option for ensuring proper air flow passing through the carburetor and blowing the finished fuel mixture (atomized gasoline with air) into the cylinder, where it is burned.
That is, if you undertake such a modification, you will have to modernize the entire intake tract of the VAZ 2114, starting from the air inlet pipe and ending with the nozzle and the carburetor itself, the fuel mixture injection system into the cavity of the cylinder block. In this case, productivity will indeed increase by almost 30-40%, but at the same time fuel consumption will also increase (by about 15%). Should this modification be made? The decision remains with the car owner.
What affects the cost?
The cost of the product for a VAZ 2114 from 2001-2013 depends on many factors. The key ones that are important in practical operation include:
- Damper diameter.
- Throttle drive type (mechanical, electronic)
- Applied damper position sensor (contact, non-contact)
- The presence of a throttle heating fitting.
- Complete with gaskets and outlet hose.
When replacing or installing a throttle, it is necessary to use new gaskets and hoses, springs and travel stops for mechanical models. An uncontrolled position, even within 1 degree, increases fuel consumption at 5,000 rpm by 70-120 g.
How to install a wider throttle body?
So, to install a throttle with a larger diameter, you will need:
- disassemble the carburetor;
- remove the old 46 mm damper;
- put a new one at 54, 56 or 52 mm;
- manually bore (cut) the gasket;
- Reassemble everything by lubricating the gasket with automotive sealant (usually red or gray).
Or you can simply replace the gasket with a new one, taking it from the LPG system under 2110; these are sold in almost every automotive parts store and are cheap. But everything will be aligned, smooth and without burrs or oil leakage.
But a 56 mm damper is not recommended. It greatly reduces the speed of air flow, causing insufficient oxygen to enter the cylinder to burn fuel. The 56 mm damper will only be relevant in cars with a gas cylinder equipment system. The throttle itself is installed using a similar method - removing the old one and installing a new one.
And again, the increase only from such a modification in the operation of the car will not give a fundamental change in power. It is better to perform the installation in combination with other methods of tuning an internal combustion engine. Installation on the Priora will not bring any changes, because they already use a 16-valve system. That is, the fuel mixture burns perfectly without unnecessary modifications. A larger diameter throttle valve is simply a waste of money and time for installation work. It is better to modify the factory firmware installed on the on-board computer, and also install a “spider” - there will be more advantages with approximately the same expenses.
What modifications can be made to complement the installation of a wider throttle body?
If possible, you should install modified firmware of the on-board computer, where the ignition start time will be reduced, and the automatic adjustment of the damper will be increased to a more open position when certain engine speeds are reached. You can also install a 16-valve system, like on the Priora. Then it will be possible to regulate the moment of spark supply and opening of the valves for exhaust. These are additional chip tuning capabilities (modifications by changing and upgrading the software of the electronic control unit). And also, if possible, it is better to test the damper in 52 mm, 56, 50. Auto repair shops are sure to have these, and the tests will take at most 20 minutes.
So, installing a new damper is not difficult. But simply replacing it will practically not change anything in the operation of the engine. However, if you expand the receiver and, in general, the entire intake to a wider one, this will already be a major modernization of the engine. Not only the power will increase, but also the speed of acceleration and smoothness when changing gears.

Big throttle on LADA. Does it make sense to install it? Owner experience
Hi all! In this text we will talk about such easy tuning of the intake system as installing a throttle valve of increased diameter.
What does this give us? It allows the engine to pass the greatest amount of air. And the easier it is for him to do this, the greater the output power will be. Let me remind you that the diameter of the stock damper on VAZ 2108-2115 cars is 46 mm. Accordingly, when installing a throttle with a diameter of 52-56 mm on a car, in theory, the power should increase, which we will check later.
What size should I install the damper then?
By installing a throttle with a diameter of 56 mm on the “stock” motor, we will give the motor the opportunity to process air even more easily, compared to 52 and 54 mm, and even more so 46 mm. After all, with the same pressure on the gas pedal, much more air enters through 56 mm than through 46. But comfort in the cabin will be lost, a jerk will appear at the bottom, and you will also need to work more carefully with the accelerator pedal. In general, without a habit, it will be difficult at first.
52 mm is “neither two nor one and a half.” The effect will be practically unnoticeable! Since the difference with the “stock” one is only 8 mm. Money down the drain, so to speak.
It's best to set it to 54 mm, which is what I did. Some kind of golden mean. But this is all theory. Let's move on to practice.
Unfortunately, I myself forgot to measure the acceleration “before and after”. But on the well-known YouTube site I found a video of one guy who was just doing this procedure. At first he had a completely stock VAZ-2112 coupe. Acceleration from zero to 100 km/h was around 11.9 seconds. Then he installed a larger throttle (56mm) and it turned out that the acceleration from 0 to 100 took one second less than before, namely 10.9 seconds.

Accordingly, when installing a throttle with a diameter of 52-56 mm on a car, in theory, the power should increase, which we will check later.
A little theory
Using a standard throttle valve, air consumption measurements showed that the engine consumes approximately 14 kg at idle, and about 22 kg at 3000 rpm. All this, of course, only applies to a fully functional engine. If we take measurements with a modified damper, then consumption at idle speed remains the same, but at the same 3000 revolutions it increases from 22 to 33 kg. This means that the increase in power is only felt at rpm of 2500 and above.
In a word, such tuning of the throttle valve on the VAZ 2110 takes place if the car often moves along the highway. In the city you won’t be able to experience all the delights of the modification.
What size should I install the damper then?
By installing a throttle with a diameter of 56 mm on the “stock” motor, we will give the motor the opportunity to process air even more easily, compared to 52 and 54 mm, and even more so 46 mm. After all, with the same pressure on the gas pedal, much more air enters through 56 mm than through 46.

Correction of a factory miscalculation
It is quite common for a throttle assembly to come out of the factory with something that cannot even be called a defect, but can still be attributed to design errors. In theory, air should flow into the space behind the throttle, for which a channel of approximately 2.5 mm is specially made.
But the whole problem is that this channel was pressed against the wall of the receiver, thus blocking the possibility of air flow. A slight modification of the throttle assembly can help in this case.
