How much boost?
How much boost can a stock '05 5.3 take? I am buying a 2005 Chevy stepside and want to put a STS kit on it since it is just sitting in the garage. What is the weak point in these engines ie. pistons, rods, crank, etc.?
BTW, I will also be running an i/c and meth.

I tend to stay a little more conservative than most, but I would stop around 10psi with the right supporting mods. You need more fuel, intercooler or meth, and a great tune. There are people who do more, but I dont like to break 'em.
Weak point IMO is the pistons/rings. Seems like the most common issue is broken ring lands.

Most 5.7L's will already take a 5.7L's piston...
