Garret's new GTX-R billet turbos
I am curious to see the power from the new units, I would think they could do at least 900rwhp in the high 30s...

I think even that would be pushing it. My reasoning is the Precision billet 67 puts out maybe 20-25% more flow than standard T67, the 4294R billet puts out about 15-20% over standard aero, and the 4508R puts out 10-15% over standard. I wouldn't expect the Billet 4202R to push more than 110 lbs/min, although it would really shine in the higher PR's
Only if you stayed stockport. That turbo would be way too big and bad for anything else

the true test will be when you guys throw that on a 13B and hit the dyno, but I'm stoked to see the maps for the 4202, I think it's going to be "the" turbo for street/strip.
Not exactly a GTX35R, but what about a HTA billet turbo from Forced Perfomance? They make several GT35R variants with custom billet wheels






someones gonna try it
