twin turbo lt1 z What size Turbos should I go with on my 94 LT z. I know very little about turbos, only what Ive read. I'd like to make between 500 and 600hp. I've seen a lot of t76 Turbo lt1 but those were single set ups. Any help would be great. I'm kinda lost on this. I've been banging my head against a wall about whether to procharge or Turbo. As of right now I'm Leaning towards Turbo. I have read the Turbo FAQ it helped some.

1st off, do you have a forged engine with boost pistions? if so, you can procharge and make 550 whp with ease..but if you want a turbo a single kit would make more sense and would be cheaper to do the same exact thing...

Look at several builds and decide which one you want to do. Packaging is the major issue.
For twins - 60-1 w/62mm turbine
Single - 76mm with 75mm S wheel exhaust
The TC series with the 68mm turbine wheel will meet your HP goals -should have a reverse split custom cam or a small conventional cam and will support the least amount of HP based on the smaller turbine.
A 219/219 113 lsa custom billet lunati voodoo series is a good compromise.
Check into what power level the stock style intake becomes an issue. They eventually have fuel distribution issues and the back runs lean.
