Garrett's are proven performance, love my PTE 6262 but if I was to get other turbo I will look into a GTX 3082R or a 35.
About the clutch, if you are going over 590whp, about 450wtq, get the twin disk and a Quaife instead of the Torsen, if not CM Stg4 will handle great.
Pump Gas 385whp 319wtq
Race Gas 551whp 439wtq
