hey so yeah i'm new to bmw's, but not cars to say the least. i just bought an 87 325e. my most important question was i wanted to know what is compatible with 325e? i know the block is the same on both the 325e and 325i (different strokes) so what can be swapped into my 325e? just certain parts (like cams, intake manifold, etc) from the 325i or the whole engine itself? do the ecu's differ at all?
also are the differentials compatible? i know the 325i has a numerically higher final drive and also can have limited slip.
