    Arrow Another mod for my RXP?

    Hi 4-tec geeks,

    I got this stock RXP, I need some more power, not handling!

    What is the best/cheapest performance part to buy for max. horsepower/acc. and speed.?

    I thought of ECU, Intercooler and airintake.?

    P.S. I will spend max. 2000 USD.

    What to do.... ?

    with a $2000 buget i would install a Riva stage 1 kit, green charger impeller and thru hull exhaust or shorty water box if you don't mind waiting for the water box. There is currently a 4 week wait.
    Spend the left over money on cool things like the Riva finger throttle/bar extension kit, etc.

    Hi Greenhulk,

    Thanks for the very very quick response!

    With Riva stage 1, green charger impeller and shorty waterbox, how much horse power and top speed will this give compare to the stock!?

    I thought that spending the money on Racing ECU and intercooler will give most fun!!!

    If you only have a $2000 buget you don't want to go the ECU route


    ECU is $899 with the greenhulk discount
    Injectors are $200
    Valve train upgraded needed to run the ECU $540 with the greenhulk discount
    Then you need an intercooler to run the ECU
    not to mention an air intake, intake grate, thru hull exhaust, pump impeller, etc.


    You are now way over your budget.

    The stage 1 kit plus green charger impeller should get you 73 mph with much better acceleration.

    Thanks mate!



    1. If I buy a Intercooler later on. Do I then need to buy some other parts to make it run ok? Or is it just plug and play!
