forged internals for turbo?
so im looking at getting a turbo for my ss. thing is, i heard that the ls3 wasn't made to handle the boost and will not last very long. i also heard stuff about getting forged internals and that they are needed/recommended when adding a S/C or T/C. i think i have a general idea of what that is, but can anyone explain this to me in greater detail? like which internals do you want to replace with forged? what about cost?
what else should be modded when adding a turbo to increase longevity? my car is only 2 and a half months old, and since modding it will void the warranty, i really don't want to risk blowing up the engine so i really want to do this the proper way to avoid that.
