garrett 76mm turbo I'm doing a 6.0 build and found this turbo new for a great price.($470) What I would like to know is this turbo enough to make 600rwhp with my set up? Or should I sell it and get something different? 6.0, truck manifold, regaped rings, arp studs, ls6 cam? is the A/R to small? what trouble will I run into. Looking to run 12-15psi.

If you build everything for low RPM it might. I made 714 with a 6.0L and TC76 with a .68AR 68mm exh wheel. Peak power came at 4500RPM and was a steady decline from there. Cam was small too. Never dynoed it with the .96 AR but it picked up 3mph at the track.

thanks, would a cam change bring the rpm up or is it the turbo. If the cam, what would you suggest? I would like to peak around 6200.

It's not the cam it's the turbo. With the .96AR it peaks around 53~5500 RPM.
The same 212@.050 cam and Garret GT76/94mm exh wheel it keeps gaining power to 6200RPM and holds to 6500.
