the RB25 is a t28 turbo with a t3 exhaust flange,

you'll have to use a top mount manifold and make custom lines for the turbos coolant and oil ports.

with a q45 maf, a rom tune, and 550 cc injectors you could do 280 - 320 hp.

Dont use it. Depending on the turbo, the R33 RB25 turbo had a ceramic wheel that broke down quickly at boost levels higher than 12-14psi. Its way cheaper to just get a new GT28R once you figure in the work to go T3 Setup.

yeah he's right,

the ceramic wheels shatter above 14 psi,unless your getting it for free, and your making your own log manifold.

but even then, its like investing into a headache
