turbocharger sizing question regarding spool time and horsepower.

[1986.5supra_kid]

There is a guy on SF with a GT3582R in .63A/R with a T3 flange, with a stock block 2JZ-GTE making 497whp and full boost by 3.2k. That was with everything stock, that turbo, and a MAP-ECU2 on pump gas. And the power held till 7k all day.

So right now I have a hx35 stock parts. I have options to go to a hybrid with 60mm or 62mm cold side but I'm after 450 or more with more middle power and I was wondering if this gt3582R would spool up as quick as the hx35 does and flow enough to get to 450-up on 16-17psi

I'm not terribly familiar with the Holset turbos, but if memory serves me, the "R" in Garrett turbo part numbers designates a ball bearing CHRA, correct? If so, I would think that GT35 would be a nice setup for mid range power, quick spool, and easily capable of 450whp.

Hopefully some more experienced members could chime in and confirm my suspicions though.
