For those of you that are looking to part together your own twin turbo kit, I have GTM turbo manifolds (great condition), Garrett GT2860RS turbo's with .82 AR (Stage 2), and 3" downpipes for sale.
These turbo's have around 20,000 miles on them, and have made 675 whp on E85. We also were able to get them to briefly make 717 but I consider that a power spike as the car was happy in the 670-680 range.
The manifolds do not look to have any cracks on them and they were used with an exhaust system that did have flex piping in them.
The TurboXS upgraded actuators will also be included.
See my build thread in my signature showing when I used these turbo's before upgrading to go a different turbo and manifold route.
