What is the difference between the BMW M30 engines?

BMW M30 big-six petrol engines for E28, E24, E23 and E34. We list 2 versions: M30B35 (3.5 liter (3,430 cc), 155 kW (211 HP), 1982 to 1993); M30B34 (3.4 liter (3,430 cc), 160 kW (218 HP), 1985 to 1988).

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 M30 family was used in chassis E28, E34, E24, E23 and E32. Before a unit is listed, the yard checks the engine code against the listing, writes down the parts fitted to it, seals every opening and photographs the real engine you will receive.
