looking for a t3 or t3/t4 in good condition, no shaftplay with 60 trim. possibly ideal a/r is .48/.63 - needs to be able to supply boost to 10K Engine RPM's (seriously)

shipped to 98146

very flexible for other turbo's

 

You state specifically what turbo you want, but it has to be able to "supply boost to 10K Engine RPM's (seriously)." Which has nothing to do with anything.

If you don't know what you need, AFTER reading the how to size a turbo thread stickied at the top of the FI Forum, THEN make a post THERE. Try telling us something about your setup and what you want out of it when you do.

 

haha joseph, you always beat me to there stupid *** comments lol.

 

well sorry for being confused about a little thing, ----. i thought a small turbo would crap out and not be able to supply enough boost at higher RPM's. i guess not.

and i do know what kinda turbo I want, but im flexible to other similar sized turbo's

95 GSR with built head, skunk2 IM, jg cam gears, what else is there to know?

 

if you knew what you needed you wouldn't have to even mention the fact that u want it to rev to 10k... you should just be asking for a specific turbo that u already kno can boost even at 10k. yeah some turbo's do crap out in higher rpm's. jus kno what ur askin for and dont mention dumb ---- like "it has to rev to 10k (im serious)"

 

Turbo runs out of steam in the higher rpms at 6 psi, or turbo runs out of steam in the higher rpms at 15 psi?

It's a compressor-limited situation. When the dynamics of the system have the engine requiring more flow than the compressor can provide, it runs out of steam. So, set a power figure you're happy with, pick your compressor based on it, and go from there. If the turbo will make 350 whp at 7000 rpms, the compressor map can probably handle 350 whp at 9000 rpms - small variance, and while it might happen at different "psi" it hasn't moved too far away on the compressor efficiency map.

If this is a stock GSR block, and you're shooting for the usual 350 whp, one of the run of the mill T04E/T3 hybrids with stage 3 turbine wheel and .63 AR turbine housing works pretty well. If you'll really be revving to 10K, you can even go a tad higher on either turbin housing or turbine wheel size.

 

im not trying to bust out 10 psi on stock gsr, im shooting for 6 psi but if i get boost-happy maybe up to 8 or 9

350hp? didn't hotrex's motor start falling apart at barely 300whp?

 

Don't confuse hotrex with reality.

 

very well put... set your goals and aim for them, dont let someone like hotsex get u down.. gsr block can take 12psi all day if tuned right. 6psi will get boring trust me. i thought i'd be happy with 7, then i wanted 10 thinkin that was cool. 18psi owns me and my roommates car at 24psi ------ hands my *** to me. but nothing compares to the fully tuned 500+hp dsm at 30psi. undescrible feelings

 

my car was lasting beautiful on 10-11 psi until my wg broke and 16 psi owned me at a 14.0 afr
