Default Turbo ls1 Horsepower estimate?

I have a 2000 trans am, with a Fast 90/90/ combo, ls6 cam, yellow valve springs, 3.73 gears....a few other mods but they dont really matter. Im wondering how much hp my car will make on 6lbs of intercooled boost? Turbo size is 69mm with a 1.0exhaust side...

I would sell your Fast 90/90 and run a LS6 inatke and take the remaining money and put it towards forging the motor. You can make 1000 hp plus on a LS6.

I wouldn't worry about a meth kit, but more so a good tune.

Good tune = Happy motor
