    Smile RXP Tips Plz

    Hello,

    My dad and i are soon to be upgrading from a 1998 XP LTD to a 2006 RXP.
    I was just wondering what type of mods will i be looking at to be able to hit 80MPH, that is our target for over the winter, because my dad and i dont have as much knowledge as you guys on 4 TEC engines.

    Thanks Nick

    Check the 4tec speeds and mods database. But you will atleast need a bigger charger, external i/c, bigger injectors, aftermarket air intake and grate, and probably aftermarket ecu, and prop to match..

    thats a very good start but youll need some more stuff and id do an 08 style waterbox upgrade like the riva box and scrap the rotax and riva thru hull. and IMO scrap the wedge, my best speed was 2 click above N so not sure how a wedge would work

    youll need

    -Boost and wideband AFR guage, Dynotune is the best

    -Gridle kit, this helps to keep the grate on at hight speed

    -Fiberglass opas blockoffs.

    Sounds like a pretty good setup.
    You will need some head work to run that ecu.
    I would go with the riva kit but some like to run other setups.
    You might need a Walbro fuel pump.
    Dont forget some block offs and ditch the opas at 80 mph+.
    You might want to look at beefing up the grate area of that 06.

    And last but not least, a way to monitor AFR.
    With those mods i would motor boost at a minimum also.

    GoodLuck!!!!
