BMW N55B30T0 engine

Power unit N55B30T0 is a gasoline engine, which is installed on cars of the BMW concern, namely – on the models BMW M2 and BMW X4.

The working volume is 3.0 liters, and the power is 360-370 “horses”.

The engine is inline and has a set of six cylinders, each with four valves. The total number of valves in the motor reaches the mark of 24 pieces. A start-stop system is present.

For successful operation it is recommended to use AI-95 gasoline. As for the consumption, the figure will be around 12-13 liters in predominantly urban areas of operation. If you mainly deal with the highway outside populated areas, then, accordingly, for 100 kilometers traveled will go about 7 liters. If we are talking about a mixed driving style, the mark will vary around 8-9 liters. It is impossible not to agree with the fact that for a high-powered power unit it is quite economical indicators.

Many people are interested in the question: how much oil does this engine consume? Usually this indicator does not exceed the mark of 700 gr per 1000 km.

In general, the described motor can be called very reliable, and its power indicators are above all praise. Based on this and other characteristics that we have given you, this power unit is suitable for any purpose, whether it is a normal measured driving or traveling on the highway at high speeds.

Advantages

The advantages of this engine, as you have probably already guessed, are many. Now we will list the most significant of them:

• Thanks to the turbine control system (M TwinPower Turbo), the air supply is as uniform as possible. This does not depend on the number of revolutions per minute that the engine produces.
• The presence of camshafts and bearings.
• Valvetronic (3rd generation) is present, as well as the “Double Vanos” system. Together, these engine elements are able to regulate valve lift and stabilize the distribution of crankcase gases.
• The manufacturers have engaged a forged steel shaft that has a very balanced base.
• The engine boasts an even fuel injection system in each cylinder. This helps stabilize rpm levels and also improves the performance of the powertrain as a whole. And all this is thanks to the innovative BMW Efficient Dynamics system.

In addition, changes have been made to the cylinder head. The manufacturers refined the gas distribution phase change system and added to it a system responsible for changing the valve lift height called “Valvetronic III”.

Disadvantages

Despite the almost perfect characteristics of the described motor and reliability in general, it still has problems. We will consider most of them based on the numerous reviews that real people have left about the engine.

For example, owners of cars with this motor note periodic oil eating. If sometimes this misunderstanding is insignificant, then sometimes the oil consumption increases to unprecedented amounts. Basically, the source of the problem is the gas ventilation valve (VVGV). However, sometimes the problem oozes from other parts. You may experience various powertrain vibrations. As a rule, the root of the evil here lies in the injectors, which fail usually after about 80-100 thousand kilometers. Sometimes there are ignition skips. There may be many reasons for this, but most likely it is the fault of caked hydrocompensators.

It is worth noting that in general this motor can be called very reliable with a fairly long resource.

Chip tuning

Despite the fact that the lack of power of the described power unit clearly does not experience a lack of power, yet with it such manipulations are permissible, which will contribute to increasing the indicator of horsepower. How to achieve the desired result? First of all, you will need downpipes. Provide the motor with a cold intake, as well as a full sports exhaust, after which you will be pleasantly surprised by the result obtained. The figure will grow significantly, and you will be able to realize all the set goals.

This engine is installed on the following models:

BMW M2 (F87)

BMW X4 (G02)
