I wouldn't run more than 7-8 psi on unforged internals... where'd you get the LT1 from? Are you still running stock pistons/rods? Are you using a stock LT1 fuel pump? What size injectors?

Thanks for your reply.
Its a 100% stock LT1 from my old '93 Formula that I wrecked, the engine has 45k miles.
Because its using a 93 ecu I'll change it to a standalone engine management system right away, and upgrade the injectors and fuel pump. Fuel lines -6 AN feed and return.
I'm really interested to know what turbo would be appropriate and what size crossover and downpipe are needed.
I'd also like to know how much power I can expect out of it.

With that kinda fuel you'll be able to run 5-6 psi pretty safely for a while, but you'll definitely eventually want to rebuild with some forged internals.
As far as the other turbo shtuff goes, I don't really know... you might want to try asking in the forced induction forum on camaroz28.com, there's lots of turbo LT1 set-ups over there.
