Ok I am kinda new to the whole engine swap scene. I used to have a 1997 Acura 3.0 cl and now I have this 1991 CRX. First off I know I wanna go B18, but wich one? with the B18C is all I need the mounting kits? The two engines I am looking at come with the ECU and tranny. The B18C5 needs the engine mount and OBDII conversion doesnt it? Is this costly? Will I need to relocate my battery? I can get the B18C5 for 1g more (with LSD) and didnt know if it would cost even more to get it running. Any thoughts?
