My Rb25/30 turbo choice

[Rb25/30nissan]

Hi Im currently building a rb25/30 and pretty much at the stage where I need to think hard about turbo choice The botton end is forged spool rods, cps,.. Id like a fast street car but a daily aswell looking for 400hp maybe abit more but want to stay on pump fuel Will the gt3582r turbo be a good choice cheers for any professional info.

Definitely a gtx3582r 1.x rear housing on  the 3L. It will make 400 easily on 98. Stock rb25s will do 400+ on 18-20psi 98

I put a 3582R on my RB30 Stagea but used .63 rear for max take off (heavy wagon) but would have preferred a .82 for a little more grunt on the track. Today I would use a modern turbo. Unusually a Wellington workshop did a back to back comparison on the same car (Skyline with RB30) and got the following results:

.63 rear at 18 psi = 350kw

.82 rear at 18 psi 375kw

I would suggest the .82 for you as it would be easy to get 400kw out of it and for a street car would drive better than with a 1.00 rear.

PS just noticed you only want 400hp not kw. You will do that with a GT3076 easily.

Thanks for the reply and your comments. What rev range will the gt3582r start spooling

What would a pte 6266 run like as a daily?

[klutched]

6266 would be a good choice as well. Its still a medium frame turbo and will make 700+ when turned up on E85. 

[Rb25/30nissan]

Ok. I can buy a new genuine garrett gte582r .82 for $1500 or a new pte 6266 for $2000 decisions decisions...

Update Just bought a 25 head from Nisswreak I believe it a 1994 head will this be ok?

[KiwiRS4T]

Has it got VCT?

[klutched]

I personally would go a precision, they seem to make good power and back the numbers up compared to a similar sized garrett.

Regarding head, should be fine if it's come off a turbo motor.

Did the physical bulk of this unit cause much packaging/fitment issues?

What manifold?  Pics would probably tell a lot for people contemplating the same unit.

[Looney_Head]

Nah it's not too bad, I am running a sinco twin scroll manifold for a rb30, they make the collector lower for the 30.

A walk around of my setup.

 

i tried to add a pic, but for some reason its not loading
