3" is probably good on the IC piping. Just use your head on the crossover, use a good transition from 2 pipes to 1, try to have 3" or so of straight pipe into the turbo, keep the sides as equal as possible, WG needs to have good airflow placement.

PT76GTS, GT-4276, GT-4580, ST76 or ST80. Those turbos leave you with more room to grow than the TC76 does. Turbonetics does have some new stuff out, if you give forcedinductions.com a call I bet they would fill you in. The TC76 really seems to choke out around 5500 rpm on a 346. The PT76GTS is a great turbo and hard to beat for it's size, it will have quite a bit less back pressure than the TC76.

For what he is doing, untouched manifolds will make plenty of power.
I would be more concerned about the small wastegate on a stock bottom end. The 38mm may only be able to control the boost down to 8-11lbs.
TC76 with a .96 A/R would be a good choice, along with any 76-78mm T4 turbo with a .96 exhaust housing.
You still need to spec out your cold side with a bov as well. Plus you still need to either tune it with the maf, or SD.

Coldside, I'll have to fab up, but it'll be a frontmount air to air intercooler. The car is a street car.
Car will be SD tuned.
