Garrett Medium Frame Gtx Turbos

[juggernaut1]

Anyone considered the new GTX3576 for an RB ?

Reported to have same boost response of a 3076 with more power of a 3076 as per post 33 of this thread link who is a Garrett employee.

The gtx3076 can't match a gt3076 for response I can't see the gtx3576 matching it

Might have misguided you with my previous post ...to clarify..... .the GTX3576 is reported to match the GTX3076 for boost response and make more power.

Ah I follow. Cheers

A tip, the GT35 turbine seems to be more successful in a .63 rear than a GT30.. This could be a cool combo IMHO

This doesn't surprise me too much, the GTX3076R seems to behave like a GT3082R - in response and power from what I've seen and people I know have gone from GT3082Rs to GT3582Rs and been surprised and pleased to report the response is no worse, but they get more power.

Imho this renders the GTX3076R and GTX3576R redundant when there are cheaper alternatives in the form of the GT3082R and GT3582R, respectively.

I really want to see a FP HTA 3076 compared to a GTX3076 back to back

Lith, you seem to have your ear on the ground, know of any?

[Lithium]

No straight up comparisons which I have heard of tbh, but so far FP GT3076R have made the highest power I've heard of from GT30-based turbos and they also spool better than the vanilla GT3076Rs so I'm already sold that the FP unit is the better option, given they're clearly both going to be limited by the GT30 hotside and the GTX seem to struggle to match the GT for spool/response.

I have been looking to upgrade the GTX3071 and cant find many reviews on the new GTX3576, it seems to be the best compromise for the new compressor's efficiency.

Hopefully I can find one of the new split Vband inlet turbine housings in GT35 size when they get released in around 2-3 months. Check out the Sema clip for the new housing i'm looking at. No word from Garrett yet as to what turbo's it will fit, it seems to be installed on a GTX28...

[GTScotT]

If thats a GTX28, I want one LOL

Divided t3 internal gate gtx2867 on an RB25 would be epic for a quick streeter

Those red turbine hosuings look like wax/plastic rather than Iron

Fu(k RB25, 2 of them on RB26

I agree, it would almost mimic the stock turbo's boost curve and then just keep going. I would guess over 300kw on e85 if the housing flows well enough.

The housings haven't been released yet so you are right, they would be plastic pre-production models. By the look of the wall thickness it will be made of investment cast stainless. I just hope they make them for other turbo sizes...

No takers for 4 of them on a VK50?

[N1GTR]

I was talking with someone the other night about twin GTX35R's on a VK56, in a tube frame front ended 180sx running on E85

....surprisingly, alcohol wasn't involved haha

[Lithium]

Why stop at twin GTX35Rs on a VK56 when GTX45Rs would be much more sensible?

[PJ.]

^ Very cool

[GTScotT]

ROFL @ sensible.

Any in any case, if you put 2 twin scroll turbos on an RB you have a '3s a crowd' situation X 2.

That being said, we will all have to go VK56s in tube frame front ends. There, I fixed it.

[discopotato03]

My gut feeking is that Garrett have a bit too much compressor capacity in a "GTX3076R" and their partial fix is to use a GT35 turbine with the "76X" wheel to get GT3582R type performance .

Time will tell if the GTX3071R becomes the replacement for the GT3076R 56T .

[Lithium]

^ Agreed, I have to say I called the GTX3076R pointlessness ages ago - before they even showed up on cars.

GTX3576R sounds like it makes more sense, though I'd rather just use something already on the market that already spools and responds better than a normal GT3582R but makes way more power as well (GT3582R HTA).

The GTX3071R haven't yet done anything which make me feel like they have made the GT3076R redundant that I have seen yet.
