Motor can be arranged. Right now i have one S52 in stock, but any motor i can get. Let me know if you are serious and we can work something out with this tranny. Thanks.
Comes with ECU also. Don't know if its a direct fit for an E30, but maybe someone on here may know or ask Charlie(Bimmersport) if it's possible. $700 for this tranny is reaaaally cheap.
