may be this was answered somewhere, but I wanted to replace my 300CE 24V 1990 engine with a 320E engine.
my questions:-
1- are there any much diff in the performance HP and Speed?.
2- will I need to change anything else beside the gear box from 4 speed to 5 speed?.
3-any other engine type that would fit with the 300CE 24V?.

Peace
Sadig
