Nitrous plumbing A1A...??..

I have SRP sportsman 4032 alloy forged pistons vs 2618 alloy pistons.
Is there a safe ammount that can be run with the 4032 higher silicon pistons?
Any piston can survive nitrous.. it's more about ring gap and tune. Forged just take a little more (a lot more) abuse than a Hyper or cast piston.
