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.

Damn, you're a baller yo. Are you doing the SEMA thing again this year? It will be very interesting to see your car compete making all that power.

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.

the specs posted on my chinacharger auction page were exactly what I got. I wouldn't buy any without specs.
