What is the difference between the BMW M50 engines?

BMW M50 24-valve petrol engines for E36 320i and 325i. We list 2 versions: M50B25 (2.5 liter (2,494 cc), 141 kW (192 HP), 1990 to 1995); M50B20 (2.0 liter (1,991 cc), 110 kW (150 HP), 1990 to 1995).

The versions share the same basic design, but the power, the turbo or injection set-up, the electronics and the emission standard change. The right one for you is the one your car was built with.

The M50 family was used in chassis E36, E34 and Z3. Each engine in the yard is inspected in Hamburg. The code is matched to the listing, the parts on the engine are recorded, the openings are sealed and the real unit is photographed.
