I have a gen 1 b16 in my 90 civic. I was wondering if that poses a problem if I were to get a longblock ls/crvtec from say importbuilders as far as wiring, etc.? Would I have to convert to obd1+? I'm figuring they use an non gen 1 b16 head. Does anyone have this setup in their 4th gen civic? I was planning on keeping my cable y1 tranny. Thanks all.

 

You could keep everything and go obd 0 or get a convertion harness and run as obd 1. are you getting your head built for the motor. If so the swap will be plug and play. I would think that you could request what type of head to use. even if it is obd 1 you can still use your obd 0 stuff.
