People are griping in another thread the TC76 with .96 is clogging up about 5k rpm on 6 liters, you might want a bigger turbo. Why 4-7 psi? Run 15psi on that focker with a forged bottom, I run 15-16 on a stock bottom end so do alot of people, you say 4-7 now you will want to crank it up as soon as you do that so plan on 15.

^LOL I am starting to think that is gunna happen to me.

Do you plan on running E85? If not 60# for 4-7psi should be good. The turbo I am putting in my 6.0 is a T76 with a .96AR and A buddy down here put a T70 with a .96 and that convinced me to go turbo lol.

don't think you will find a internally gated turbo big enough unless you go twins.
