Hey guys, I picked up a new precision turbo for my y8 build.

I ended up getting the sc34 which from the looks of things it is identical specs to garret 57 trim t3/t4E.

compressor= t4E .60 a/r 57 trim turbine= t3 .48 a/r stage 3 76 trim

I originally ordered it with the .63 a/r hot side, then switched it to .48 after discovering that with my crap tastic gear ratios in a y8 s40 tans. I might be dropping out of boost between shifts with a .63

My goal is 400 whp, Do you guys think this turbo is capable of it?

Build is a simple y8 stock head, custom rods/vitara pistons 8.5:1 c/r.
I am hoping that with like 25 psi I might still be able to hit 400 whp even with the .48 hot side.

 

Not with a .48 housing and a .63 housing work just fine on a d series. When making that kind of power its going to take a larger turbo than a 57 trim IMO to hit 400 unless your going for that hp on race gas only then you can max it out on 400

 

.63ar turbine housing would work better than the .48ar
