So far I've just got the airbox mod done for performance. Soon I plan on getting a GMPP Sport/Performance catback, too. However, in the future I definitely plan on porting my blower. In order to do this, I also plan on getting injectors and a custom tune. Well, with the injectors, I might as well get the Stage 2 kit.

So, my question is.. will the Stage 2 injectors and the stock internals (pistons mainly) hold up to just an intake, exhaust, ported blower, custom tune, and full GM Stage 2 kit? Also, what type of psi would you expect me to be running with these modifications? I want to keep my engine from exploding, but I want a nice amount of power.

Check.

So now I know I can run stock pistons up to 350 HP or 290 WHP, and I'm almost positive these mods aren't pushing that limit. I should also run the 60 lb injectors.

Given those restraints, is there anything else I should worry about such as cooling, spark plugs/wires, head gasket, etc?

 

Should do a cooling mod such as cobra h/e 1 step colder plugs if you want
