Ive searched and searched for answers all over. YES... there are threads that cover this.. well, kinda. However, they all redirect and point the person in the other direction suggesting not to buy that specific engine and go with this one over here instead, it would be cheaper and blah blah blah. Anyway, I've already got my engine, tranny, etc. Im just confused on what i need to do with it to work. I have a fully built b16a2 out of a 99 em1. I have an integra "a1" cable tranny with the 4.40 final drive so itll match the b16 rpms, etc without modification or need of a hydro converter and alk that garbage. My biggest concern is going from obd2 on the engine to match my rex. Its a 90 si, mpfi from factory and all that good stuff. Im not worried about the ecu right now, ive got the conversion harness for that. I just need to know "how" to convert my obd2b engine to work with my car. Again... i know theres threads out there on this, but not really ON this. Theyre mainly deterring the person from doing the obd2 b16 swap and less on the "how" to do it part. So any help on "how" i can convert my engine would be appreciated. What Dizzy, alternator, etc is needed to match? Thanks!
