Is NX a wet shot or a dry shot?
Either way, I wouldn't go over a 100 shot.
Any form of forced induction wears parts faster than normal use, but in my experience, once you start producing the heat, wear, and combustion that a 125 or 150 shot would produce, you're asking for trouble on stock parts. It may not go today, and it may not go tommorrow, but something WILL go. It may be something somewhat easy like a head gasket.... it could be something bank draining.... you never know.
An x-pipe will definately help, but to be honest, to get the numbers you want somewhat safely, its time to consider a new head\intake combo or other similiar engine work. Put some forged pistons in that brute while you're at it....
Just my opinion...
