How much PSI is safe on stock compression? I have a Turbo that I salvaged off of a SISU with very low hours on it. I would like to use on a Silverado. What are the upper limits of PSI I can boost a stocker.

Doesn't matter so much as to how much boost, what really matters is HP, and the limit is around 500rwhp in most cases...

try taking that number down to about half that.
unless you're putting 400* air into the LS1, its going to be making 500hp long before it reaches 20PSI..

thats because 1 . you have a big motor 2. you have a big turbo
20 psi of boost out of a t28 does not = 20 psi of boost out of a T04E 60-1 or T67 r T70 etcc

do not turbo, or supercharge a stock motor, thats an accident waiting to happen, its too much stress on the bottom end of the motor, u might want to get heads and a Camshaft from MTI first. go to www.motorsporttech.com

5500 would easily do it for a used kit. but be ready for bs things and little odds and ends.
do it the first time and do it right, you won't have problems out of it.
get sloppy with Forced Induction and you lose things...
