Get your daughter on a 800 154 and see will do fine, if you buy something smaller you will be buying another sled next winter cause see will get bored of a little sled
My 2011 etec aerocharger turbo running 9lbs boost is probably no more then a honest 210-220 and hi elevation so i dont think the xm is gonna be anywhere near 300...lol
If your planning on turboing next summer, talk to Ken at Mountain Magic he will put you into the right clutching so you dont have to spend abunch more money after you turbo, Im running paragon secondary and a P-85 primary on my etec turbo.
