    With the stock IC you should get the 15/20R impeller. You will still have to add around 1.5 mm pitch to the trailing edge.

    The 15/22R will be too much pitch using the stock intercooler.

    Stock x prop suppose to be 14/23. Several reports show that they measure arround a 12.5-13/21 - 22.

    You could work with it but I would reccomend exactly what GH stated.
    Get a 15/20, much better prop to work with.

    I ran a rude1 and had a GH 15/20 and it worked very well.

    You mean a stock rxp prop? The answer is yes, but the efficiency will be poo. Read: the rpm will be correct but the top speed won't be that great. I ran 76-77 mph on a bent up stocker but it took a lot of boost/power to get there.
