1995 Pontiac Firebird

I bought this car as a project. it was pretty beat up. no engine, 5 speed trans, but i have big plans for it :0) I'm planning dropping an LS1 backed by a T56 tans. I'm a little experienced with turbo engines, so i would like to fabricate a turbo system to it. but i still can't decide if i want to go the turbo route or straight engine...
