Quick Question

There are so many variables to these questions;
In stock form, keeping things safe, 7500 RPM's. Have people gone over that; yes. Throw in big cams and expect to rev higher in stock form; no. Are you willing to upgrade springs and retainers?
How long to spool a GT35r on a 2.0 or a 2.3; What's the A/R on the exhaust housing?
PSI on a certain turbo for a certain whp requires a lot of math, compressor maps, and serious trial and error. The only way to know for sure is to try.

I am less conservative than Larry I guess, I have been reving my stock head with 272's to 8,000 on a daily basis for over a year without issues. Now on the 05 I have (being installed on Monday) a stage 3 head from Buschur Racing, and will rev that as high as Dave says the stock bottom end can take without comming apart

Larry is correct on the other issues. Way to much variation to tell you any real answeres.
