I drove a Supra with a GT3582R. twin-scroll T4 1.06 A/R housing. The tune was a little rough but it spooled slow. My car drives nice with the VVT and big A/R 2871R, I think once I get the boost turned up it will make 370-380whp and have excellent response.

No it's not. The turbine on the speedyracer 2870 is 52.9mm and the turbine on a Garrett t25 series is 53mm and a t28 series is 53.8mm. The speedyracer is more like a 2570.
Don't trust the names these guys slap on these china turbos. They aren't the real sizes, just names.
Compare the turbines:

The china 3076s are the same way.

I'm aware that the specs posted on ebay are not to be believed enitrely. I said that because Levnubhin measured that same turbo, and IIRC it was very similar to a 2871.
