Hi. I just bought my sister a 1990 RS which has a bad B18A1 in it. I can't sem to find a place to buy a newer B18a, so I was thinking about dropping a B18B in it. I know the B18b is OBD1 as oppossed to the RS being an OBD0 car. Can anyone tell me what I need to do to be able to use the OBD1 motor in my OBD0 car? Many thanks in advance.

P.S. Ii tried searching on this website and on the interenet, so please do not respond with "try searching" or some other dumbass comment. I am looking for help, not wasting my time.

Thanks.

 

its not hard to run the b18b as obd0, just reuse all the electronics from the b18a1 onto to the b18b1.
