Is a T70 T3 EXHAUST FLANGE TURBO CHARGER STAGE 4 good for a 2000 mustang gt?

I have a 2000 Mustang GT and I am trying to up the looks and power. I have just purchased BBK cold Air Intake/BBK 75mm Throttle Body/BBK chrome long headers/BBK O/R X pipe w/o converters, slim chrome radiator with fans, chrome oil catch can, chrome starter, chrome altenator, full chrome dress up kit including valve covers, 4.10 gears, I just put a Black Widow Type III body kit and lambo doors on it as well and much much more....I am getting a 75-150 hp nos kit changeable to 300hp and now i need to find a nice supercharger/turbocharger, I assume I will need need new pistons and roller cams and crankshaft or whatever but not sure the best way to go from there as well. Any help/suggestions are greatly appreciated....thank you in advance...
