So guys with bolt ons, fuel and a tune what would an rb20 with a factory rb25 turbo be good for? Ive been searching for an hour now and cant find it for the life of me.

Go figure I find it 5 minutes after posting this thread. But still what WHP is it capable of?

I can tell you I jsut pulled off my rb25 turbo and AM performance downpipe and went back to stock rb20 turbo and elbow and I felt a noticeble decrease. I was running 12-14 on the rb25 probably around 230-240 to the wheels.

Dude, Definitely and u can literally feel it.

This is the fav. combo for RB-20 DET here in Thailand

- Swap into RB-25 turbo ball bearing (Make sure it's black turbine)- Dump pipe (optional)- LSD 4.3- 3" Exhaust pipe- HKS air filter system (or something else)- Nismo clutch- Rb 26 fuel pump- Tuned ROM (not neccessary)

Better try it and you'll know.
