    185 converted to 215??

    Are the supercharges the same? I know the Pistons aren't. What else does it take to make a 185 a 215?

    the flywheel and SC gears are different
    the ecu stock rev-limit is different
    the drive shaft and props are different on some
    the pump is plastic on some 185 and all 215 are aluminum

    Can I change the gear from the 215 sc and put on the 185? And then put the 215 injector in?

    the gear can be changed
    do not know if the injectors are different but the fuel psi is
    you cant change the injectors without a 215 ecu or flash your 185 ecu

    Been said on here many times, it'll cost you a fortune, come will loads of work n headaches and you'll end up at best with a bastard machine worth less than it was worth stock.

    Best trade it for a 215. Will be cheaper, quicker and hold its value.

    VERY good advice by tornado!

    The little 185 will never be a 215, mainly due to the pump tunnel being smaller, the pump / impeller being a 155mm vice a 159mm. You can swap all the other items out and add a external IC but it will never be equal.

    Our GTX 185 is slightly modded and is old reliable with over 200 hours on it and just goes and goes. I suggest you leave it alone and get something else that will set your hair on fire, like a new RXP-X.
