hey well im thinking of puting in a first gen b16 in my 91 crx si and was just wondering wat all i need to do. a lot of ppl have told me that u dont needafter market motor mounts if u put a 1st gen b16 in a 91 crx and ive seen it done in a civic sedan. but i was j/w wat kind of wiring i would need to do i no i need to wire vtec. tried searching but didnt find n e thing.thnx ahead of time

 

You basically need to wire up vtec solenoid, vtec oil pressure switch, knock sensor, and second o2 sensor.

Its been a while since Ive done one of these swaps, but I think thats about it.
