i have a 93 da obd1 integra. I blew up the b18c with my turbo setup. I think im going to go b20b. I have a chipped p28 running my b18 turbo setup for now. Will i have to have it re chipped if i use a b20 with an identical setup as i had before? And also i know that the b20b is a honda crv obd2 engine. If i swap my b18 intake manifold over onto the b20 will my obd1 harness and engine computer run that motor with no problems?

 

you'll need to retune regardless. no any two motors, will run identical.

 

would prob idle and drive just fine but I would trust it under boost
