It would kill you to keep quiet for even 30seconds! Hurry up and go buy your supra!

I think that the 500R at boost levels approaching 30 psi will get you to your goal. The cold side is similar to a T04Z from what I've seen.....

This was a really informative post and helped me make a decision. I've decided to recommend the GT4094R. It has a 70mm inducer on the compressor, and a 77mm turbine wheel. Available in 1.09 a/r. Sean at A-spec said it would be better than 70% efficient at 30 psi.

If you were looking at that big of a turbo I would have you atleast look at the S472 from Borg Warner. Even with the 1.32 a/r turbine side they spool up (20+psi) before 5000rpms and they are about half the price of a GT40.

This would be another option for you.

Definately worth a mention here! If money is not too much of an issue, though, gt4094r wins the race.

You could run the S472 but you don't need to be stuck with the larger 1.32 A/r Personally if money is not a object of concern, there are some pretty cool solutions/combo's out there to fit just about any need.
