Rb25 With Rb20 Ecu?

[Charlie4401]

Hi guys i'm looking to put my RB25 into my patrol. I have a RB25 motor with a R32 turbo so it has the 10psi spring and i all so have a R32 Mines ECU i just want to know can i run the R32 ECU with the RB25 with a RB25 wiring loom??? if not could anyone tell me Y???

yes you can but it will need to be tuned to suit and it wont run the VCT

If you want to retain the vct but still have a remappable ecu, use a z32 item. Requires some modification though. If you dont want to remap your engine. Just get an rb25 ecu.

Yeah you can run a s1 rb25/loom/etc from a rb20 ecu... there may be a few minor wiring changes though. Also as said above, you'll need a window switch to run the VCT.

Why are you running a rb20 turbo on a 25? They flow less than a 25 turbo and won't spool up much quicker...

If your going to stick with the mines ecu, you'll need to put rb20 injectors in it, rb20 tps and a coolant temp sensor from memory.

Personally, I'd buy a z32 300zx ecu, get a nistune board installed and plug that into the rb25 loom, then ditch the rb20 turbo for at least a stock rb25 turbo.

What do you want from it?

ok well it looks like i need to sell my Mines ECU and buy a R33 ecu. I got the R32 turbo cuz it was cheap and was only just down the road. I'm putting it into my partol so just looking for more power than a carby RB30..lol
