you will need the conversion harness, but its not worth it to switch to a jdm p72. From what i've heard, the jdm p72 has a speed limiter, and isnt good for chipping....i think it would be a waste of money, but thats just MHO

i would get a usdm p72 obd1...but what are you plans for motor modifications? I have a friend selling a stock p72 obd1 and a mugen chipped p72 obd1...and I also sell chipped p28's...depending on your plans or your motor mods right now, i can recommend something for you.

for now i just want a stock p72 obd1...i plan on puttin on comptech I/H/E for now and get a VAFC...
maybe in the future put some skunk2 cams, IM...i heard hondata is the best to chip the ecu? wouldn't a JDM p72 be better than a USDM p72?

Re: JDM p72 okay for GSR? (KriLYu)
yes..hondata is the best way to go........Theres not much difference between the jdm and the usdm p72. But i would just stick w/ a usdm one. If you do plan on getting the skunk2 cams and a new IM, then i do recommend selling the p72, and look into trading or buying a chipped p28, or just look directly into hondata

I've dyno'd back to back with both USDM and JDM P72 OBD-I ECU's. Same fuel cut rpm and seemingly the same fuel mapping. No changes in power or redline.

Yes, if you want to convert to obd1, the obd2B-1 conversion harness is needed. JDM ecu's are usually smaller than the usdm ecu's. And yes they are basically the same.
