2S li-po with a nemesis 8L for a crt.5 ?

I just received my monster conversion kit for my crt.5 and I already have a couple of 6000mah 2S maxamps, so i was wondering if i can use this motor http://www.finedesignrc.com/nemesisspecs.htm which gives 3072rpm/v
and also what kind of pinion should i use? something big like close to 20t? if this motor is not good, any suggestion for a motor ?
Thanks for your help guys!
