I have the opportunity to buy a chipped P28 (mugen program) to run my 94 JDM GSR. I am currently using a stock P72...do you think i will see any gains by swapping the ECU? I have ITR cams, exhaust, and intake. Nothing much. Thanks.

As well, how much would a ECU like this cost?

what intake manifold are you running? if you are running a skunk 2, then the p28 would be the way to go.

I have a regular GSR intake manifold.

run the P72

when u upgrade to agressive cams or the skunk2 intakemanifold
chip a P28 or chip your P72

Well, i do have ITR cams in there...but i am not sure if they are considered agressive cams.

stick with the p72 unless u get the skunk2 manifold

yeah, I agree - I'm chipping my old p28 so I can run it w/ a S2 manifold + ITR cams, if you run it w/ the stock gsR manifold it will not function the 2ndary butterflies and kill your bottom end (some info on jdmhondaparts.com under the ecu tuning section). If you want to keep the gsR manifold, you can chip your p72 to a similar program to the p28 and keep your 2ndaries functionig (again, jdmhondaparts.com). hope that helps some
