    Gprxpjersey's build thread

    Here's where it all started. I blew my 07 gpr motor up (crank bearing let go) and decided to build a conversion.
    Want to thank a everyone who helped me along the way, especially hydrotoys and everyone else on this site who shared their builds and also Jerry for giving us this site and the wealth of info that goes along with it.
    Also want to shout out Inkaddict for physically helping with the build, beerdart, addicted, and all the boys of ECP.

    More motor pics, its a low hour 06 rxp motor with greenwheel and riva washers. Going to start out with a stock setup with greenwheel and 4inch intake for now then by the end of next season I plan to upgrade to a 1st gen rude with external i/c.

    Next we stripped the ski, turned it upside down and trued the hull but I only have one kinda crappy picture of it from my phone because I forgot my camera. We spent a total of about 6 hours trueing the hull and filling in some damage from beaching the ski so much.

    After the hull was trued the next thing to do was seal the shoe and transom. It was so much easier doing it while the ski was flipped over than the first time I did it. I had to redo it because once we flipped the ski we realized the shoe was not only crooked but sitting a little low.

    After doing the bottom end (except for the intake grate), the hull was flipped and the hull cuts were made as well as taking the midwall out. The hull cuts were done as a 2 man job, one making the cuts and the other stickintg a vaccuum right next to the wheel to suck up the dust. This worked out perfectly and minimal smc dust escaped. Instead of remove the goo where the intake grate mount is but burning it we chisled it out. No toxic smoke that way.

    I have both an rxp gas tank and an efi gpr tank. Just this past week I decided to go with a closed loop setup so I will be using an efi tank with the old oil tank to hold the coolant. I ride 100% saltwater and like my setup to be as durable as possible. I still have to mount the ecu, run the elevtric, and put back in the gas tank.

    This past week I got some goodies in the mail. First was my driveshaft, its an 07 gpr i-shaft/rxp shaft combo. I went for this setup not only because I already had the 07 i shaft but also because I like the idea of it better. Just personal preference. A forum member on here was kind enough to help me out getting this done (beerdart).
    I also just got my MC-1 waterbox.

    I would be careful about using the oil tank as the coolant resivoir. You will have to find a way to get a pressure cap on it, then you will have to modify it with bigger coolant fittings for proper flow, etc. The oil tank may sit lower than the engine, so you may have to put an air bleed somewhere in the head to purge all of the air out of the cooling system. It sounds like more work than what its worth. Just throwing some ideas out there for you to think about.
