Sorry for confusion. My "82" E21 is mechanical fuel injection, but I heard you could convert top end and injection system to electronic. I just don't know what series and year models would work the best. Anybody know?
@Dave: what do you mean with "the only way i know of to get a FI 4 cylinder of BMW manufacture"? The M10B18 and M40 4-pots were also fuel injected?
