If you're looking at brushed, I would go with a 19 turn wind, but more likely I would look at getting a brushless system. There's less maintenance involved to keep it running well, and there is a plethora of motors around that will satisfy any speed you would like to go.
I would look at brushless systems made by Speed Passion. They have their Cirtix line of ESC's that are a little more simple, and then they have their GT2.0's and GT2.1's as their more complicated, but better featured competition line.
