i am swapping a b18a1 into my 91 civic dx, it allready has a zc motor in it. i need to know if i need to get different shift linkages, can i use the stock motor mounts from the b18a1? and can i use the shift linkage from a 90 or 91 integra? and will my wiring harness work? i believe i should have an obd0 harness right now. please help me.
