Questions about a twin turbo setup on a truck.... I am thinking about pulling the Radix and swapping it out for a pair of small turbos. Get some good dished pistons to drop my CR back to around 9.5:1, run a Z06 cam with LS6 springs and stock rockers, sell all the extra crap, buy a pair of decent-sized turbos that would spool quickly. Truck is big and heavy, and still needs to have good street manners, still needs to tow and be able to go off-road.
Questions:
1. How much boost can I safely run on a 9.5:1 6.0L with 91 octane?
2. How much boost can a stock manifold take?
3. Would a truck or car intake manifold be better suited?
4. Any benefit to running a 90mm TB when it's set up in a blow-through manner rather than a draw-through?
5. What size turbos would work well that would spool quickly and get me to the max amount of boost that I can safely run?
6. Make custom manifolds or flip the stock manifolds and run them towards the front?
7. What kind of heat shields need to be made?
Thanks guys, I did some searching and I am starting to get a little familiar with turbo-speak, but I don't know much about them at this point....

1 - 9 pounds intercooled should be fine
2 - more than your engine can handle
3, 4 - i think you should just focus on the forced induction part
5 - i would call forced inductions if your serious, they will set you up with a perfect pair of turbos to match your application
6 - the actual turbo piping and labor for welding my headers was a small fraction of the overall project cost, i would recomend having headers made for your application if you want a nice setup, or if your into the quick and dirty setup you can make a cross pipe to join your manifolds and just run a single turbo - but since your asking about doing twins I'd assume your willing to dump some money into it.
7 - that really depends on what is too close that needs shielded from heat, where are you planning on putting the turbos?
Me not being real familar with how the truck engine bay is setup its hard to make recomendations on pipe routing and stuff, I'd suggest doing your homework and getting familar with your vehicles engine bay and how other turbo kits are setup. Maybe you can even find another TT truck and borrow some ideas, I got lots of my ideas from harlans old setup and his pictures were quite helpful.
