    You can get a factory TPI from GM Performance Parts that's already available with the motor.

    It's called the "Ram Jet." /forums/images/icons/wink.gif

    Tuned Port Injection Specialties........... has one.........so does Arizona Speed and Marine.......... if I remember right. Not for the faint of heart (or light of wallet) /forums/images/icons/frown.gif . Ram Jet is a good way to go as it is all inclusive, just add high pressure fuel pump (and new lines IMHO for safety), power wire and ground and pretty much go. Downside to RJ is the lack of O2 sensor........which Az Speed and Marine has a kit for - otherwise there is no closed loop operation. /forums/images/icons/shocked.gif RJ is also not cheap.

    I've seen the RJ 502 in an older vette. It's a sweet setup, and very reliable. Worth the money, if you're looking for dependable, reliable horsepower.

    You mean that's not pocket change? /forums/images/icons/confused.gif /forums/images/icons/crazy.gif /forums/images/icons/grin.gif /forums/images/icons/tongue.gif /forums/images/icons/wink.gif /forums/images/icons/laugh.gif /forums/images/icons/blush.gif

    Someday the 80 will have a FI 502 but that's only when the motor blows in the 78 (the 78 will get the pulling motor out of the 80 and the 80 will be upgraded)...........wait did I just hear a voice say "pipe dreams".... /forums/images/icons/grin.gif


    Is that motor open or closed loop?

    Open loop AFAIK. Maybe thats still a "good" deal for a new 502, but why you'd throw away some performance to have a "standalone" system for that kind of money, not quite sure...might as well go carbed.

    Yeah, it's open, but the AZ Speed and Marine O2 closed loop kit solves that.......... /forums/images/icons/tongue.gif

    For $8000 I gotta buy even more stuff? I thought the RamJet standalone controller was "revolutionary" lol. /forums/images/icons/smile.gif Only playing folks, as soon as GM puts a TPI 502 in a truck, there will be plenty of swapping fodder lol.
