Anyone considered the new GTX3576 for an RB ?

http://www.atpturbo.com/mm5/merchant.mvc?Screen=PROD&Store_Code=TP&Product_Code=GRT-TBO-185&Category_Code=

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.

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.

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.

  • 3 months later...

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...

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

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...

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.

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 .

^ 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.

    • So could it be assumed it has been installed intentionally with potentially a power FC boost controller kit? 
    • Had my rig on Matt's dyno at PITS the other day. After a few years between tunes I added a few sensors and swapped intercoolers. Result. 553hp at 26psi. Not bad for an FJ20 that was built in 2007. The problem.. It filled the overflow bottle on hard runs which leads me to believe the head gasket isn't sealing. I have a coolant pressure sensor which was reading cap pressure at 22psi and occasionally overrunning to 23/24 psi on deceleration after a pull. It was not spiking. It has arp2000 head studs and a cometic gasket. As its been 18 years in service, I pulled the engine out and head off. Everything looks good but we obviously have an issue. Where I'm at.. Years ago I had the same issue, I checked the stud tension and they were all over the place. Some at 60 to 70 and some up near 90. I nipped them all to 100ft lbs and this stopped the water push until now. I believe this compromised the gasket back then. What do I do? 2 options are..  1) I bought arp 625+s, which I could put in with a new gasket. Thinking Kameari this time, reassemble and try again. 2) strip the block, get fire rings machined in with copper gasket and try that. I do not want to push it more than 28 to 30psi. I think the turbo will be out by then anyway. (G30-770). My other concern is the long term ability of a copper head gasket. Are they streetable for years? I feel like a new gasket with the new studs will probably suffice, but I don't know. Any thoughts welcome and advice on copper gaskets and fire rings. Thanks!
    • I'm a fan of the JZX110, and the Aristo. Big cruiser cars, and with the factory cars, super comfortable and feel like you're driving an armchair! And the JZ motors are a pretty nice engine too, especially with some basic mods.   The import process, and the need to be able to trust people, and the fact there's so many scammers around is what ever puts me off wanting to go through that ordeal!
    • I don't care for these at all, but at least the underside looks straight and not rusty. A good basis for a long life. Many cars from Japan have been lifted with forklifts and f**ked almost irrepairably.
    • Yes, but it's not dumb or dodgy. You can build a perfectly good boost controller from a pressure reg, a relief valve (looks same same as a reg if all from Norgren or SMC, for example) and a check valve. I ran one for years. Only superceded with  EBC because I could get one for cheaps and wanted finer control.   THis mod is certainly not a sketchy boost mod, provided the boost is kept below the "spin to death" threshold of the turbos.
