LS3 and boost...
What all would be required in making a setup on the LS3 to withstand 15-20#'s of boost on a consistant basis? Also the same goes for the L99?
I am not fully knowledgeable on the LS3 or the L99. I would assume different rods and possibly pistons would be a must, but past that I really don't have any idea.
Specifically thinking years down the road when the new Camaro has been out for a while and there are turbo kits available what all would be needed.

No, it is for the new Camaro, and thinking of getting one if the aftermarket is open to my needs.

what size turbo are tou talking about... for example a t3 w/ 15lbs isnt as much air being pushed through as larger turbo @10lbs (which is more effeciant)
but for what you are asking i would say you will definatly want to add thick metal head gaskets to drop compression some and replace head bolts w/ arp studs. upgrade fuel delivery and add larger injectors. what numbers are you trying to get to as far as hp/tq?

Billet main caps and pistons would also be a requirement. Thick headgaskets are not going to change your CR to the point at which you would be safely away from detonation while running 20#'s of boost. A small turbo would unlikely be able to support this. Think more around the lines of a 76mm sized turbo or blower equivilant of the Procharger F1A.
A decent setup with supporting heads and cam with that boost amount should net 750+ to the wheels easily.

There is absolutely no reason to run that much boost on a large displacement motor. Simply running the right camshaft to increase the dynamic compression ratio at a reasonable boost level [12psi] will allow you to achieve more power than the stock bottom end will put up with. 20psi is for motors which have no displacement, which is hardly a shortcoming of the LS3.
