    Please help me ...

    I have some questions and i was wondering if you have the answers for me
    First of all i have a 2006 Rxt which has Power Filter Kit , Riva Pump Wedge
    , Riva Intake Grate , Power Cooler with Pro-Series BOV for Stage III ,
    Compressor Impeller Large + Spacer (igni-power) , Metal Clutch Washers ,
    Shorty Waterbox , RIVA Rear Exhaust Kit , 4-Tec Rideplate Skegs , Breather
    Catch Can Kit and RIVA Thermostat Kit .
    I think that i'm going to have problem at high rpm's cause the compressor
    impeller is large . Should i buy injectors or ecu or both and which ones ?
    With all this stuff on my watercraft which pump impeller should i buy ? What
    do you think also about the Nozzle ?
    Is there anything else that i need to buy for my watercraft (for the engine)
    to be safe ? (Ceramic Hybrid Supercharger Bearings , Valve Train Upgrade
    Kit) ???

    Thank you !

    With all this stuff on my watercraft which pump impeller should i buy ? Depends on your mods, If you add a aftermarket IC a 15/20 will work for you What
    do you think also about the Nozzle ?Riva sells an adjustable venturi that works great and easy to change out
    Is there anything else that i need to buy for my watercraft (for the engine)
    to be safe ? (Ceramic Hybrid Supercharger Bearings , Valve Train Upgrade
    Kit) ??? Riva rear intake, if you go with an aftermarket ECU you'll need the valve train upgrade

    Thank you !

    1 thing I would change of what Alex said. Last time I checked, Skat sells the same adjustable nozzle but with 5 rings instead of Riva's 3 rings and they're the same price.
