M30B32

Despite having a capacity of 3210 cc, this engine appeared in many cars badged so as to suggest 3.3 litres of displacement, such as the 633i, 3.3 Li, and 733i. It has a bore of 89 mm, a stroke of 86 mm and a capacity of 3210 cc. In the E24 633CSi, it uses Bosch L-Jetronic fuel injection.[5] The US version used L-Jetronic from 1978 until mid-1981, changing over to Motronic fuel injection in June of that year.
