BMW M52B28 engine reliability, problems and repair

The eldest representative of M52 family was firstly introduced in 1995. The series of engines also includes M52B20, M52B24, M52B25 and S52B32. This motor was used on E36, E39 models as well as on E38 728i autos produced by major Bavarian automaker. Cylinder block was made of aluminum with the exception of autos which were exported to the USA. M52B28 engine is square: Bore x Stroke – 84×84 mm. Cylinders diameter is the same as in M52B25. Crankshaft has increased stroke, piston compression height is 31.82 mm while connecting rods are 135 mm long. The size of injectors is 250 cc.

M52TUB28 modified version was produced in 1998. It was equipped with cast iron sleeves located in the cylinder block. Double-Vanos engine included new connecting rods and pistons as well as renewed and improved cooling system and electronic throttle body. Specifications of M52TUB28 camshaft are the following: duration – 244/288 deg, lift – 9 mm.

This motor was mainly used on BMW autos with 28i index.

In 2000 successor from new M54 series was introduced. M54B30 engine replaced its predecessor in 2001 and production of was stopped.

Disadvantages of 2.8-liter engine are the same as its related M52B25 has. HERE you can find detailed information on reliability of the given engine.

BMW M52B28 engine tuning

M52B28 Stroker 3.0. M50 Manifold. N/A

The easiest way to increase the level of power is to install M50B25 intake manifold as well as cold air intake. At the same time you need to upgrade camshaft and tune ECU. S52B32 camshaft will be the best bet for this purpose. Such kit will guarantee from 240 to 250 HP which is perfect for a city ride and will not cost you a fortune.

There is another alternative to turn your engine into 3-liter M52B30. You need to purchase M54B30 crankshaft to implement this project. Standard pistons should be milled down to 1.6 mm. The rest of bearings should be left stock. M50B25 intake manifold is recommended for improvement of HP characteristics.

M52B28 Turbo. Supercharger

The easiest way is to buy and install Garrett GT35 turbo kit using M52B28 stock internals. After Megasquirt tuning is completed M52B28 Turbo will perform 400 HP when the boost is 10 psi/0.7 bar. It will be followed with a perfect acceleration. Such kind of engine will be the best bet for your everyday drive. It will also show high level of reliability.

BMW M52B28 stock bearings are able to handle with 14 psi/1 bar pressure. Sometimes this rate can be a bit higher. If the HP rate is higher than 450-500, stock pistons should be replaced by forged pistons with 8.5 compression ratio.

If you are a true fan of superchargers, you will certainly benefit from ESS TS2 supercharger kit which is produced on base of Lysholm supercharger. Such systems make it possible to upgrade your engine up to 300 HP and more without replacing stock pistons.
