i was wondering if i could swap a obd1 gsr
motor into my 90 civic hatch dx..and keep it
obdo with a b16 pr3 ecu..i heard you'd have to
change the intake manifold due to the secondary
butterfly's...i know it'll run better if i change
everything to obd1..just wondering what do you
need and how hard is it..to convert from obdo to
obd1...i know i could probably do a search..but
hey i'm tired..i just got outa work .....thanks..

need to add some wires for obd1.. i dont think its any different then really a dpfi->mpfi (which u will also have to do).

just make sure the engine comes w/ obd1 stuff. (dist, IM, o2's etc.)

The ecus are different. They don't have the right plugs. You can get a conversion harness from hasport. I think That one is like $200. If you have a 92 and up civic it would plug right in.
