Ok what the hell. I goto the HASPORT swap guide, and it tells me for a B20 swap into a 5th gen civic I want a PR4 from a 94-95 civic... but when I look up PR4, its the EARLIER ECU and not the "OBD2" one they seem to be talking about. So what exactly am I looking for, for my swap?

Someone said the P75 is plug and play - but even the P75 I seem to only find that it is 94-95 (maybe this is the one HASPORT was talking about?) or 96-98... that part makes sence since MOST CRV motors are 96+ (but they were made in 95) Should I just save myself some trouble and get a 95 CRV motor?

 

for b20 swap, i'd use the a P75 (LS ecu) or the CRV ecu.

both will work well with it.

 

um a crv ecu will be an automatic not to mention the crv transmission is 4wheel drive. who knows what that ecu controls. and its OBDII

your best bet is a LS ecu or have a p28 chipped.
