The GT3071R doesn't offer any more flow then the IX turbo. That's the main reason it's useless in this community.
And it doesn't match the IX turbo configuration in either spool or transient response. As for the GTX version, I can't imagine it doing anything that a factory-framed upgrade doesn't do better, while converting the factory configuration to T3/T4 to accommodate the Garrett unit represents an added expense to boot.
People always talk like the stock turbo is responsive...but it's not.
For sure, you can make that argument against expense though. Myself, I see value in separating from factory frame setups if you want to go beyond an IX turbo though. Particularly if you are the type to buy an aftermarket manifold either way.

How is a 9 turbo not responsive? It may not be a K03 on a direct inject 2.0L Volkswagen GTI motor with full boost at 1500rpms, but it is still responsive..
Boost threshold, sure, it does well. Time to boost...not really. They are two different things so comparing to a K03 1500 RPM boost threshold doesn't make sense as that's not at all what I'm talking about.
Seems like everybody that goes to the TME, FP White, HKS 7460R, Tomie 7960, etc. all comment on drastically better spool over stock while making as much or more power.
Similarly, I've driven cars with GT30 and GT35 derivatives and absolutely the GT30 cars do have late boost thresholds that on a dyno makes them look nearly as laggy as a GT35. But without a doubt, the GT30s have far better time to boost behavior above the boost threshold then the GT35.

Added more boost. about 23 peak boost. Feels a lot better than my stock gsr turbo so I ain't complainin' currently making the same power as on stock turbo E85 and 2psi less.
