Ok so I just purchased a new turbo I am excited but I have a couple of questions I'd like to get thoughts on!.... Its a Garrett T3/T04E 60 trim with a turbine A/R of .63 and a compressor A/R of .60.... I plan to run 8-10psi on my re-tune and this is my daily driver.... My question is do you guys think I will have a usable curve with this application and where about in the RPM band does a turbine at .63 A/R spool, with a tubular mainifold?? thoughts would be appreciated

 

maybe about 3200-3500 my guess

 

I have a 54 trim/.63 AR and I love it. Full boost is around like 3000+ RPM's ish.. great spool. You will have fun.
