The engine comes with 190 horsepower and 280 Nm of torque enough to fulfill all daily driving needs with a sporty performance that BMW customers are used to. The M52B28 engine does not panic whether it accelerates onto highways or gets through the city streets.

The M52B28 can be deemed as one of the more reliable engines in the BMW line up. With a good maintenance, this engine can easily die after more than 200,000 miles with little problems. With that said, it is necessary to note that oil changes are a necessity and that coolant flushes should also be made on a regular basis in order to avoid overheating, which is an issue frequent with the M52 family of engines.

Nevertheless, as a true engine, M52B28 is not infallible concerning the possible problems. 

There have been reported difficulties with VANOS system, especially poor seals which eventually wear out due to age, causing rough idle or power loss. The cooling system is another typical problem, and it should be cared of otherwise it could break. Nevertheless, the M52B28 is still an engine that does pay off well should one know how to take proper care of it, and therefore, it is a stable engine for those who navigate in the depths of its inner workings.

Applications of the M52B28 Engine

M52B28 engine was applicable to several models of BMW and all of them enjoyed smooth power delivery and compromised functionality. It was used in both the BMW E36 328i, a high performance-oriented compact sedan and the E39 528i, which added further luxury and sophistication to drivers that wanted a bigger sedan. Another vehicle where this engine was applied was the BMW Z3 2.8; a roadster which was lightweight and energetic to drive.

During these models, the M52B28 offered above average performance during the time. A case in point is the E36 328i which gained popularity with driving enthusiasts due to its handling and all around driving. The 328i was capable of handling with its 190 horsepower being able to easily match its more powerful competition, and the match of comfort, agility and power is unique.

The M52B28 also gave the Z3 2.8 more pep to drive. The Z3 2.8 was quick too, with almost magical 50/50 weight distribution and smooth power delivery of the M52B28, this roadster could be fun to drive and it became one of the best small roadsters of its era.

M52B28 Engine Performance Tuning

Although those who desire to explore the boundaries of the M52B28 engine more can take it tuning to open up even more potential. A naturally aspirated 2.8L inline-six is a very ideal candidate to any type of performance modifications just like the intake and exhaust upgrades. One of the advantages that an engine can obtain thanks to a performance cold air intake is the better breathing of the engine, which translates into a more responsive throttle, and a bit more horsepower.

The other common modification to M52B28 owners is ECU tuning. Reprogramming the engine control unit (ECU) improves air-fuel ratios, ignition timing and results in increased horsepower and torque throughout the rev range offering enthusiasts increased flexibility. Also, a faster running exhaust system, such as high-performance exhaust headers, and free-flowing exhaust outlet can be used to add a few horsepower and make the sound of the working engine more interesting to the driving experience.

The M52B28 can be turbocharged should one want even greater power. It will need a lot of tinkering but a turbocharger kit will easily boost power, putting an extra 300 plus horsepower on the cylinder head.
