To4/rb25 Exh Housing...on Rb25 Wise Decision?

[Ryanrb25]

hey guys, I have supporting mods, 660cc injectors, power fc, walbro pump, FMIC ra ra ra. Was waiting to buy either GT3040 or GT3540 with .63 but recently picked up a cheap, close to new t04e housing a/r 60 with RB25 rear with steal wheel real cheap. A good mate of mine had this on his rb20 and made 240rwkw with 18psi, Is this a suitable turbo for my rb25 and how will they compare to the mention gt30/3540 turbos...they are obviously different but would like to know what sort of drivebility and power output on around 15-18psi i would be looking at...

thanks guys, tried to search but couldn't find what i was after..

Without the wheels specs/trims etc. Its absolutely impossible to give you any idea mate

It would just be a guess.

But what i can tell you, is it wont make anywhere near the power with a RB25 rear housing as its a very limiting factor.

thanks mate, the rear housing has been machined out to its max and the wheel is that big...lol...ill get specs tomorrow....

If it made 240rwkw at 18psi on a rb20 expect to make the same power with about 5 less psi easy and with a better torque curve.

I have a similar turbo and the guy before me made 210rwkw at 20psi on a rb20, I made 235rwkw on 12psi.(<--Both cars were auto aswell).

If you got it cheap, good buy.

Good luck,

My main point was if you can make decent power on low boost with the turbo your engine will thank you for it..
