    With all the right parts, including the RXT-X SCer and IC with RXP nozzle and right prop 75 would be fairly easy to achieve.

    You would need to get a RXP-X loom. You need the ECU from the RXT-X and then get the VTS enabled if you have it on the RXP.

    Honestly I would get it running as a 04 RXP then add some mods to it. You can run the SCer from the RXT-X with a set of 42lb injectors, if you want to run an external IC like the RXT-X does then you would need a RRFPR as well with the 04 ECU.

    The engine its self is almost the same between all years apart from small changes in the valves, camshafts and the oil system. You can use the block from any year, its just all the bits that bolt onto it.

    I converted an 07 rxp to a stock 255 set up with rear air. It is easily a 75mph ski on the stock p-x prop reptiched.
