    Or wait for a nice ski already done up and buy it to save money, time, and the hassle

    X Charger
    15/20R 4 Blade Prop
    External Intercooler
    Aftermarket Air Intake (4" front or a rear air setup)
    2 Degree Pump Wedge
    Adjustable Nozzle with 81mm Venturi Ring

    That should get you into the low 70s. Add a set of aftermarket valve retainers and a ECU reflash for more speed/rpms.

    Don't forget fueling.

    You'll need bigger injectors (probably 42's with an X-Charger) as well as a RRFPR if he's going with an External intercooler.

    You don't need a rrfpr. Go 50# injectors with the x charger
