I know there´s a lot of guys out there who have swapped in M50's, S50's (some guys have all the luck), S14's, whatever. Obviously those are the most popular choices. Now, are those the only ones? What are the issues fitting other, maybe newer bmw´s motors in E30's engine bays? size? harnesses, sensors, ecu, electric issues? transmission?
I mean, there's a host of options out there, makes me wonder why some go unexplored.
just asking, since I haven't seen any threads related to this. If there is any, please forgive me (and post a link!)
