Safe PSI numbers?

what is the max you can boost on GSR piston’s?
Im just trying to get some helpfull info before i spend alotta money on this turbo kit.

well theres safe and theres more power and less safe…untill detonation

What id shoot for is a goal dont try and go as high as possible, Id personally push anywhere from 7-10 psi be carefull tho if ur pushing anywhere near 10 and its untuned, your gunna total your entire project.

300whp. oh and get it tuned

Boost AS MUCH as you want until you get the desired whp/wtq numbers you are after. I would stick with anythig under 350whp on a stock bottom end.

Rating an engines capacity by PSI means nothing, It’s all about the output in the end that the amount of psi produces :slight_smile:

PSI has nothing to do with it, Or almost nothing

Depends on what turbo,
10psi on a t25 is much diffrent than 10psi on a Super T3 etc…

Its all CFM’s. Just depends on what turbo your using etc…

T3/T4 NON BB.

what stage is the exhaust and what trim is the compressor? also the A/R’s

I’ll take it it’s prolly around a .63/.60 with stage 2/3 and 57trim wheels. Around there. So 8-12 psi roughly will net you around 250-300whp give or take.

.50 A/R COLD
.63 5 BOLT STANDARD HOT SIDE
3"INLET DIAMENTER
2"OUTLET
.57 COMPRESSOR WHEEL TRIM
.60 A/R COMPRESSOR
.63 A/R TURBINE
57 TRIM

TURBINE WHEEL:

EXDUCER:2.48"
MAYOR:2.89"

COMPRESSOR WHEEL

EXDUCER: 2.07"
MAYOR:2.36"

excuse me, it a T3/T4 T04E

t3/to4e bigshaft?
pretty nice turbo :slight_smile:

Turbo XS turbo off ebay I see

YEA, people have told me their turbo’s and intercoolers where good, but besides that their products crack or crumble…How’d you know?

You copy and pasted their specs sheet off the Auction. That’s how they list the specs for all their stuff.

You know too much about the itnernet when… lol sigh

lol, thats great… :rofl: are those any good? the t3/t4 t04e?

honestly get a used garret/turbonetics and rebuild it… thats what i did and she runs beautifully and got it all said and done for about 500 :slight_smile:
Ive heard bad things about their turbos but u cant always believe what ya hear… but id buy a turbonetics
and yea the t3/to4e will spool about 4k (dependent upon setup) but its a large turbo soo itll put u in ur seat and keep u there

This man tells no lies! Thats the exact same turbo I have (yes, same brand too :/) Nearly 1000 miles and strong. I get full boost at 4k and I got whiplash the first time I opened it up all the way. Have fun, be safe :]

5 -9 psi no more on stock internals my friend had his on 10 for like a couple weeks and he raced me and blew up haha rod right threw his block ruined his turbo header and something else i dont remember(besides his engine haha lol)

i have a pte sc61 67trim its an awesome turbo and its cheaper lol. its the same turbo that the second fastest s2000 uses so it must be good.

On my old SC34 I was boosting 14psi on my B16 and reving to 8600 day and night. :slight_smile: rating safety by PSI is as bad as saying VTEC is no good for turbo because of the “jump”:wink:

Do you have turbonetics or XS Power?
