    05 RXP RIVA ecu

    havent been on the site in a year or so. Decided to blow the dust off my parts collection and start bolting them on my ski.
    I purchased a virgin Riva Racing ecu and 50lb injectors. Im Wondering what other recommended parts i need to get for this thing before i add the new ecu. Its got an x charger with intake and exhaust stock IC right now. Thanks guys

    drill out the manifold so you can add a AFR gauge

    forgot to mention ive already ordered new head studs and fly wheel bolts. I know the valvetrain need upgraded but to what extent. My old mechanic was just telling me retainers and keepers but i see alot of guys saying springs as well. as far as th AF guage is that just to look for catastrophic situations? any mods to the fuel system if the ecu and injectors are paired up properly?

    Those 05's are prone to valve failures. I'd highly recommend replacing your valves. Go with these Supertech valves they are lighter and stronger than stock and also cheaper

    as far as retainers go, you may as well go with the supertech spring and retainer kit. This kit is just slightly more expensive than going with just retainers

    AFR gauge is just to make sure everything is in check. You can adjust your air fuel ratio by adjusting your fuel pressure up, or down. This is the fuel pressure regulator for your 05

    whats the best way to mount 02 sensor in an 05 ski. from what i recall the manifolds usually get jacked up on the older skis. would a riva waterbox screw up the r&d mount?

    DashPac does work on the 2005, but you still need to install an O2 sensor somewhere.

    I personally like drilling and tapping the exhaust manifold. Buy a newer one and install. There are a few used. Keep yours on the shelf to put back on latter.
