    Going with a Rude SC... What other changes needed?

    Hey guys, I have decided that I want to put a Rude SC in my 07 RXP. Right now it is completly stock. I want to keep the ski reliable as it is ridden every weekend during the summer months.

    If I put in a Rude what other mods do I need to install to keep everything safe and to maximize performance from the Rude?

    Here is what I was thinking:

    Rude SC
    Riva Intercooler
    Riva Valve Train upgrade kit
    Riva ECU
    50Lb Injectors
    Skat 3 Blade prop (I am looking for acceleration not top speed)
    Riva Grate

    Anything I am missing here guys? Any help would be apprciated.

    I would definitely look at putting some riva pro block off,s or RE block off,s. You will need them at the speeds you will be going to keep ski from porposing.
    I would also go with some sort of 4 inch air intake (preferbably rear air) as your rude needs all the air it can get.
    You might want to look at upgrading your exhaust system.

    For the Exhaust... can I just have the stock WB upgraded or would it be better to upgrade to a GH?

    I actually have a set of RE block off's that I bought from Jerry last year but have not installed them. I ride in surf along with lake riding... I dont think I want to go with rear air. So I guess the riva front intake or a custom 4" air intake.

    Thanks for the info so far

    Parts selection looks great but you will also want the thru hull exhaust. Hold on tight because it will be very fast

    Thanks GH... yeah I went and added that to my list... actually added a bunch of other things. Also thank you top banana for the water box suggustion.

    Here is the new list:

    Riva Rear Exhaust Kit
    Rude Charger Conversion

    Ride Plate Skegs
    Riva Intake Grate
    Riva Sponsons
    RXP Reduction Nozzle

    SS Wear Ring
    RR Front Engine Mount

    Riva Pro Series ECU

    Riva Pro Series Fuel Injector Kit (50lb)
    Catch Can
    Valve Train Upgrade kit

    Valve Train Upgrade tool
    RR 158 Degree Thermostat
    Skat 3blade prop
    Groco Intercooler Strainer

    Custom 4" Front Intake
    Riva Pro Series Intercooler
    GH Stock Intercooler Block Off

    If I go with the items listed above will I need anything else to complete the assembly and install? Basically I want the list to be 100% complete so when i put my order in I dont need to worry about anything being missing.

    Do I need a new gasket for the engine after I install the Valve train kit?

    The only changes i would make to your list to help save you some money is get the Piranha engine mount instead of the RR. It's a little cheaper and does the same thing.

    Also, i have the 50# injectors in the store for $200 (same as Riva injectors)

    Looks like you have a very complete list of parts. No gaskets needed when doing the valve train upgrade.
    Also, i will loan you my valve train tool so no need to buy one.
