just upgraded piston , how much the motor can take?

[nismo1003]

I searched around. I heard the stock rod and cranfshaft are strong. next spring ,I wanted to upgrade some 8.5 cr piston and ring first. for just this upgrade? can it handle 15-18psi with 550cc injector cobra MAF T3/T40e (pump gas). my goal is around 350-380hp.

If it can be done with stock pistons (it has) then I'm certain you'd be fine with some forgies in there Oh, but just a disclaimer: stronger pistons wont make up for piss poor fuel management If you detonate badly you will obviously still run into problems no matter how strong the internals are.
