PSI is not a limiting factor, it is just a variable as. Be more concerned about the power limit, not the psi "limit".

Like patrick4588 stated, your flange will more than likely be T3, not T3 and T4.

I would also suggest an injector/pump upgrade and go over your setup well with whoever is going to be tuning the car. Be carefull w/ the c/r, but theres no need of being scared of it.
