not sure the cooper would handle too well with the 13 turn motor
unless you widen the track.

the cooper only accepts 16, 18, and 20 tooth pinions.
with the sport tuned motor (stock silver can motor with advanced timing) it's recommended at 18tooth pinion.
I've run it with a 20tooth pinion and 1/10 scale touring car tires
and it's pretty fast already...almost 19t mod motor speed on regular TC.
any faster though, and the cooper will flip.
On top of that, the gears will easily burn out and you don't have much in terms of motor cooling.

anyways, i'd probably suggest the 18t pinion for a 13 turn...too much speed and it's uncontrollable...
