well as most of you know i blew my motor, on taking off my intake i checked my turbo and there was a 1/4 inch of shaft play so i ordered a t04b for my turboII its a p trim, .63 trim with a 96 a/r exhaust side with a divided exhaust housing, i got a couple of questions.



if i run 10psi of boost where will i see full boost?

if i run 14psi of boost where will i see full boost?

am i going to have to make custom oil fittings and oil lines?

is the hks cast iron manifold good quality? is it divided or undivided?

and will the powerband be ackward if i just run 14 meaning will it hold full boost and not fall off till redline?

and will i need bigger primary injectors?



yes i know i need an ems, fuel upgrades. my car already has a haltech e6k, 1600 secondary injectors and im going to order a supra TT pump.

hmm so anyone can help me with this?

Hks is undivided. Its also overpriced imo.

You won't need larger primaries.

Spool depends on porting, so does when it will fall on its face..

How big is the exhaust port?

depends on the manifold, the hks undivided will spool later

So we have the fact that it depends on the porting, the manifold, now I 'm going to say the turbo. What do you mean by .63 trim? Is that 63 trim or AR .63 compressor housing? How big is the inducer and the major of the compressor wheel? If it's a TO4B it could push enough air for anything from 175hp for a small TO4B to 500hp for a big TO4B.

personally i like the to4 series of turbo........



my car starts boosting at 3400 rmp and starts hiting full boost at like 4700-5200 rpm on my car currently full boost is 10lbs right now
