    stock RXP intercooler onto GTX

    will a stock rxp intercooler fit onto a gtx? does the intake manifold on a gtx have a removable block off cover where the intercooler would go?

    the gtx has a 17 tooth sc gear as opposed to a 16 tooth gear on the rxp, how would this affect things? need to change the supercharger gear?

    You would be better off with an external IC like the XS IC. To be able to run the RXP/RXT 16-tooth gear, you would need to change your GTX flywheel to a RXP/RXT flywheel... Ron

    If you have both a gtx and an rxp, I think you could swap the intake manifolds and you would not have to use stock IC block off on the rxp and run an external IC on the RXP.

    There is a Rotax gear set avail to do this. remember tho--- the 215 gear set spinning the SC faster increasing boost a stock 185HP ecu is not mapped for the increase, and doesn`t have the same rev limit to benefit from the labor and cost involved.


    there is more to it to make it run correctly and reliably...
