Rb25ecu In Rb20? ? ?

[lush31]

got a quick question. Im only new to the twin cam rb engines. Im into the r31. Will a rb25det ecu fit in a rb20det silver top. And will it run good. With no problems? A lot of people will read this and say wat a stupid question. But only new to the turbo rb's. Cheers guys

I don't think you'll have much luck with it as most rb25's have vct which the rb20 doesn't. rb20 ecu's are easier/cheaper to remap (tune) aswell.

match the ecu to what head your using.

You do not want to use a 25 ecu into a RB25. Sure it could be done. But you would waste hundreds of $$ to go backwards.

Buy a 20 ecu and whack it in.

any idea how much a 20det manual ecu will run me?

edit: searched... i'm an idiot
