ok first off you have a 93 .... so why in the hell would you convert it to a obd2 car .. its already obd1 ?????? secong off .. a b series is a bolt it swap its VERY EASY . takes 2 people maybe 2 hours from start to complete if you have all the tools and required stuff to do the swap ...... i recomend any b series for your FIRST swap .. dont do turbo until u put a b in and try it for yourself ... if that doesnt satisfy you .. then boost or supercharge .... my b17 with type r cams is a reallllllllly fun sol ,, but ive always wanted to boost mine so thats what im aiming at ...... dont let noone tell you the b swaps aint easy .... its like puting shoes on ... very easy
