Default Garrett GTX 3576 .82 or .63 a/r?

Anyone use gtx 3576 here? I currently have hta 3586 with tial .82 exhaust housing, will use it for daily and highway driving but I think it might lag on tracks with lots of corners and short straight with only one long straight.

So I'm thinking of using a gtx3575 for much faster spool, i just can't decide what a/r exhaust housing. Target whp is around 500 with E85 and around 450 with 95 oct gas. Leaning towards the .63 housing for max spool.

.63 should be fine for what you want!

i have the gtx3582 on a 2.5L the boost hits around 4000k the car made 512whp on pump on turbo xs's dyno. i feel like the 3576 will be good but the gtx3076 might be the best turbo for you in terms of response. youll def make the power you want and be way less lagy. i know someone who made 585 on e85 with a 3076.

Do you know if the exhaust housing of the gtx3076 compatible to the housing of a 35r? I don't like to replace my UP that's why i'm thinking of gtx3576 coz the exhaust housing is for 35r while the compressor housing is for 30r, minor modification only for the IC coupler and pipe from hta3586

Exhaust housings are different between the GT(X)30 and GT(X)35 families, so GTX3076 will not be a drop in affair.
The GTX3576 would be the easier 'drop-in' option for you - exhaust housing is a bolt-on and the compressor housing is also 4", like the HTA3586.

Thanks

I guess i'll just go for .63 housing of the gtx3576.

My old setup was crawford 35r turbo kit with t3 .63 housing. Replaced everything with hta3586 with tial .82. So much easier to swap turbos with the Tial v band exhasit housing

are any parts off a gt30 the same as a gtx3576? , but I feel bad wanting this after my new center cartridge replace,

main question is, what can I do to purchase this gtx3576 that can slap on my old school perrin piping, has the slight 2.5" for the last inch of the downpipe where it goes to the hotside of the turbo, 4 bolt flange

rough price of said turbo? what interchangable parts are on this, and lastly, what kind of difference power band wise would I be looking at from my gt30, .82 hotside, .60 compressor to the gtx3576 in either .82 or .63, Im looking for more whp then my current 52lb could max around 450whp, but dont want it anymore laggy then it already is

If you're using E85 I'd ALWAYS go for the larger housing. You've got more volume leaving the engine and it's going to need more flow. If you took the time/money to do a decent back to back test I feel like you'd find a smaller difference than you would like on spool. It's not apples to apples but I picked up 40WHP going to a .96t4 over a .82T3 and it lost nothing in spool on our S2000.


Thanks

So it's murky to see the RPM but it looks like under 400-500rpm spool for 35whp up top? I'd carry the .82, What kind of dyno/fuel was that on?

Nevermind, helps if I read your post. Sounds like you want to keep your current tial hotside? If so, you'll need to stick with a 35r sized wheel on the hotside as already mentioned.

If you want to sell your 35r with the hotside, you could probably get a GTX3076 with a new tial hotside for that. Not certain, but I'd be suprised if the 30r v-band inlet diameter was different than the 35r v-band inlet diameter. This should let you keep your up pipe, but call tial and verify if this is your situation.

This should answer your question regarding up pipe commonality:
