i got the same set up...using a chipped p28 (92-95 civic ex) ecu...custom program from a fellow honda-tech member...

you can use a 98-00 type r ecu if going obd2, otherwise chipped p28 (obd1)

you're converting from a obd1 car to obd2b?...good luck...hope you have a obd1--->obd2b conversion harness, some obd2 sensors like crank fluctuation, and a secondary o2 sensor

if it were me and the car is OBD1 I would go hondata on a P28 and create a tune for that motor since CRVTECS don't exist from honda directly

oh sorry no you don't need a conversion harness since the obd2b engine harness will plug directly into your obd2b si ecu. However you might want to check up on the extra obd2 sensors that your SI ecu will be picking up. if your motor is obd2 and has all those sensors, you should be fine. oh yes, you want no cel with o2 sensors? then add the secondary one after the cat or so.

stay obd1 but want to use the SI engine harness? get a obd2b--->obd1 conv harness...

YEP, B20 V-TEC (GSR HEAD) IS THE WAY TO GO
OBD-1 WITH A P28 (92-95 CIVIC) ECU NO NOCK SENSOR. CHIPPED AND TUNNED, ALSO IT WOULD BE GOOD TO GET SOME NEW FUEL INJECTORS TO RUN BETTER...310 CC OR HIGHER
