More info would be handy! What car? FWD or 4WD? That's a pretty ordinary turbo with limited boost/power available!
I'd be very concerned with gearbox @ this stage. This is your weak link with the projected power output you desire............have you a FMIC? increase the capacity here then, look @ injectors/larger turbo/increase boost
I can see you experimenting til' you get it right due to the variables your expecting from one build, good luck!
Then there's the brakes/suspension mods to consider.......
