What is the difference between the BMW N52 engines?

BMW N52 naturally aspirated petrol engines for E90, E60 and Z4. We list 2 versions: N52B30 (3.0 liter (2,996 cc), 190 kW (258 HP), 2005 to 2011); N52B25 (2.5 liter (2,497 cc), 160 kW (218 HP), 2005 to 2011).

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 N52 family was used in chassis E90, E92, E60, E85, E87, E70 and E91. 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.
