Hey guys
was wondering of what kinda of power i should spec with this combo on a SR 94-96
combo :
GT25 60 trim 60 mm compressor, (.60 A/R hsg), w/ 60 trim 53mm GT25 turbine wheel in .60 A/R based
Power FC/ boost controller
Nismo 740cc injectors
is it possible to reach 300-330WHP with that combo? if yes , is that kinda of power to much stress for a daily drive car?
other details like intercooler/koyo rad/ etc etc

hey, your injectors are way too big for a GT25, 550cc would be fine, and why a GT25? Why not a GT28 series? This way you can make the power you need and not put stress on the GT28 rather then trying to stress the power out of the smaller GT25 ya know.

I would get bigger turbo for those injectors and just make the power easier with the larger turbo at lower psi.

that is what i have for now . i can upgrade to a GT28 pretty soon and i only paid 270 for the turbo
so do im able to put that kinda of power with that setup? or i need a GT28?

I think it would be hard to get 300whp out of a t25, at least reliable power. I would say just run the t25 moderately until you get your t28 then let all the power flow, with a good tune of course.

with t25 boost up top will fall off and you wont be able to get 300.

think about it man. A stock s15 motor puts out 250 to the crank on T28 and stock boost. So maybe 270 to the crank but I doubt to the wheels.
