Rb25 In R32

[bretto]

hey guys

ive just got a 32 registered that has an rb25 in it, but the wiring loom is all rb20 still. does this mean i will have to put an rb20 power fc in it or can i use an rb25 one?? also im getting a td06 20g kit on wednesday but i need to know if i can put the turbo on and safley use it without upgrading the ecu and only run like 1 bar of boost?? my current mods are 264 cams, adj cam gears, 1.2mm metal headgasket, sard fpr, dont know what type but very noisy fuel pump, fmic.

thanks......brett

What ECU are you using now?

20 or 25 one?

i heard the looms and comp are the same just different maps maybee series 2 might be different

the only diffrence that can be seen on the wiring loom side is that on the rb20 there is no vtc control and injector triggers for cyls 5 and 6 are swapped.

i just got a rb25 pfc for use on my rb20 and i plan on swapping pins for clys 5 and 6 and it should be mint.
