Hi all. Quick question. Would a 1990 535i engine be a good candidate for a swap into an E3? It's an auto trans, so could I just keep my 4 spd and bolt it up? Would it be better to swap injection to carbs or is that dumb? I'm just surfing the web and thinking too much...lol. It would be fun to swap to the 3.5, but I don't want to deal with fuel injection wiring, etc..
