    jhill's 04 rxp build

    I figured I'd start a build thread for my ski as I begin to reassemble the ski and get it ready for the summer. Lot's of upgrades have happened over the winter! Engine should be on it's way home this week from Slow91. Pictures to come when it arrives and as soon as progress begins. Engine was completely disassembled and rebuilt with new cp 9.5 pistons and everything new, rebuilt oil pumps. I had the cyl head completely done at the same time, ported, polished, valve job, decked the head, new supertech springs and retainers and new supertech valves.

    Current mods on the ski:
    Riva rear air intake
    Riva catch can
    Riva intake grate w/ r&d girdle trued to the hull
    Speedfreeks ride plate
    Speedfreeks pump shoe protector
    Solas 15/20r which will need to pitched for the new setup
    RE pro opas block offs
    CMD marine + WB2 w/ autotune
    Walbro fuel pump
    Turbosmart fpr800 regulator for now
    Jet trim set cover
    renthal bar, umi switch housing, farthing finger throttle and odi rogue grips
    DIY 160* stat

    Upgrades include:
    Slow 91 Custom ported and polished head w/supertech springs and retainers, supertech valves and modded valve guides to flow more air
    Slow 91 Built bottom end with CP 9.5 pistons, all new bearings, new timing chain, and new hardware.
    ET 68-140 charger with triple bearing mod
    Custom Bell core intercooler made by RAGE FAB (Gold06rxp)
    lightened 29 cam
    60# injectors
    Vtech handheld reflash (going to reflash to 9200)
    Ported and port matched exhaust manifold tapped for o2
    Riva 08+ waterbox and mid pipe setup
    Riva/ARP headstuds
    Adjustable venturi nozzle
    08 oiler mod
    06 rocker shaft setup
    New upgraded fly wheel bolts
    Danny's fuel rail with black an lines and fittings

    I need to reinforce the stock manifold as well. Trying to get to high 80's maybe even 90. I'll have pictures along the way.
    I'm sure I'm forgetting several things. Enjoy, Jacob

    I'm the same. My ski is just white with a Jettrim seat cover. Sure doesn't look like it goes 90mph.

    I picked up a solid 2-3 mph with the speed freeks plate. It does what he claims. Sits a good bit higher out of the water. I also have a riva wedge and vts trim rod.
