With the .63 power will come in with more of a punch later on, this is at the expense of LOST power lower down, 32psi, I'd seriously reconsider upping the turbo size for long life.
Although you cam make the power I'd seriously consider some porting, even having the exhausts ports cleaned up will bring the power in a lot lower and harder, and also help the top end, but not 100% essential.
