I am wondering about some OBD issues for a head swap. I have a 1990 civic hatch and I'm about to do a swap. I am about to purchase a B20 when a friend brought up a good point, OBD2. If I run an OBD0 b16a head from the jdm crx, will it work in conjunction with the B20 bottomend, as far as the OBD? I am trying to avoid as much elec. problems as I can. Also, will the B trans fron the Jdm crx work with the B20? I fugured B's a B right?
