Thread: 250 Parts

    250 Parts

    Some one needs to make.....

    Larger pully to jump Roots to 15 psi
    ECU to match
    Lighter intercooler
    Prop????
    Exhuast Mod.
    K&N or Large intake kit.
    Mirror block off kit
    Fuel pump and EFI's
    Pistons.

    Seeing how this is a 15 F motor then the Riva SC ECU might work
    The RIVA forged piston will work.
    The RIVA EFI,s and Fuel pump should work.
    TJ Cams should work.

    Gentleman I think we will all be shocked as to how fast parts will be availible. Alot of R&D on the 15F motor has been done already. Boost is boost weather a Roots or a Vortech

    I agree, parts will come fast. Boost will easily be adjusted by pulleys. Im digging this a lot!

    I think the 15-f uses forged pistons. If this is true for the 250, they should be up to the task of adding ponies.

    The Riva 15F Endurance Kit should give it around an extra 5mph or so for a mere $2K. Hard to say at this moment what top speed could be with with new ski. I just know this ski has a lot of hidden potential, especially from 15F aftermarket parts.

    Riva SC kit has Forged piston the have a different crown to lower Compretion. This Boat already have that done but do not have forged one. So it would seem to be reasonable to do a swap out to Forged.

    Cams will pop in.

    Let me make a prediction.

    """""" RIVA Stage-1 that pushes out 300HP availible by March """""""

    Im sure Im gonna get beat up for this one.

    First thought to mind was "What a hater" then I laughed because its kinda funny.

    Riva will be on it. Damn half the works already done.


    Forgot to add the free flow exhuast mod of ditching the muffler and boring out the water box.
    Anyone wanna buy a bunch of stock stuff for a Ultra 250.

    Keep digging it and go down to the dealer and open your "Good Times" account. Send me your fist payment stub.
