    Trying to put together my own Stg1...

    I am looking to put together my own Stage Something and would like you guys input and suggestions and predictions. Not looking for bigger injectors or a new ecu at this time. So, give me some feedback guys. Thanks.

    14/19R
    Riva Intake grate
    Riva 2 degree pump wedge
    Riva rear air intake
    Vortech impeller
    RE block offs

    Or any suggestions as far as "don't get this, get that, it will do you better".

    Good list. The only change i would make would be substitute the Riva SC impeller for the Rotax Racing high boost. (they are on sale right now)

    You won't need bigger injectors to run this impeller until you go with an external IC.

    Thanks for the input. It's always nice to hear from the Master. Any predictions on this setup if I did change SC impellers and with the change would the 14/19 still work fine? Thanks.

    42# injectors and either the 15/20 4 blade or 15/19 3 blade. I would take a gamble and go for the 3 blade

    Yes, because you don't have an external intercooler. You will not get the full effect of the RR Wheel until you get the combination of the ECU and the intercooler. If I were you and have the money, you next mod should be an aftermarket intercooler instead on the RR impeller. You will make more HP this way until you buy the RR impeller.

    Muddy is right ..I have been looking into differant SC combos alot lately.
    Im doing a stage 2 and i want to use the stock injectors and ecu..so basically i have to go with the riva wheel like you have..heck you get a 15/20 4 blade or a 15/19 3 blade prop and a riva intercooler and your pretty much a stage 2 yourself..Later
