how much boost

i have an audi a4 b5 1.8t(awt) quattro, i just purchased a gt2871r, new fuel pump, injecters, fpr, manifold, and looking into some software dont know what type of software yet but my question is, what kind of boost can i handle on the motor, without upgrading internals, that will come next after i recover from this purchase. what is my max boost that i am safe to run.

It's the tune you go for not so much the psi, the power a stock engine will take is around 320-330bhp.

thanks for the help, then just one more question, when i start to do internals what should i start with to be able make more hp?

thanks agian

Well most say just a set of scatt rods will do the trick but if you are looking at a solid 380+bhp mark then I would say Rods & Pistons to be safe.
