So if I build my motor I might have to go stage 3 like Squeeze n that's more money ill have to spend. Wish someone had actual experience with the gt28s on this platform and not what the manufacturer "claims" it can handle.

Sam posted a graph in my thread of a stage 2 making 608whp 15 PSI.
If you go with the stage 3 like me make sure you get the .86 A/R , I am learning the hard way backpressure with the .64 A/R I have now and T25 turbo flanges. My goal has been 700whp+ all along ,and after speaking with Garret the PRI show I am sure I should have went bigger.
