    at what point do GTX SC owners draw the line for mods with the stock fuel system?

    how much can it take before you need injectors and/or fuel pressure regulator

    I`d have to say stage 2 Steve...
    remember I had the Riva wheel, RXT ECU, 58 psi reg, etc and she was good to go. major improvement over stock. The only thing I didn`t do was change out the SC gear set...PR...

    I found that adding the RXP fuel pressure regulator really helped my acceleration at all speeds. I only had a wedge, prop and riva gate with 4" intake and metal washers, of course.

    are you checking your plugs frequently? the 58psi reg is best suited for the RXT/RXP ecu`s (example).

    no doubt it would run a bit better, more fuel...
    but then again, more air, more boost, more RPM`s would be the ticket...PR...

    all stock 2003 GTX SC

    3" Air Intake
    Exhaust (Power Pipe)
    Rotax Racing High Boost SC Impeller

    what would you do for fuel? leave it alone, add a RXP fuel press regulator in, or what?

    with mine i went the limted with the cast pistions so i knew i needed the rxp fuel pump i still have the stock injectors in my 03 gtxsc even with the 05 i/c, s/c over drive gears rr s/c fan & rxp ecu added the extra oil pressure spring what i have is a 215 stage I +, since ur not turing any more r's the stock fuel pump should b fine its when u start 2 run more r's or bigger injectors when u run out of fuel pressure, but i dont think it would hurt 2 have the rxp fuel pump
