Ok, right now i have a obd 0 b16, and i need to switch over to obd I cuz i really want that bar sticker. anyways, i was thinking about just getting the ecu, harness, injectors etc...but my block is a 89, and my car is a 90. So i think i'm just gonna swap a whole new long block in.
If i find an obd I longblock, ecu, and get the wiring harness for it, how difficult would it be to get into my existing car? any kinda of problems i might run in to?
