The closest you will fine will be either a BWA motor or the readily available H&R Jack Rabbit motor. The BWA and NC1 both turn about 13Kat 12V, the H&R turns 14K. H&R also make the Hawk @ 18K if you want a bit more speed. Depending on the style of your track more speed may not be wanted. 
  The BWAs are out of production and getting hard to find.
The H&R motors can be found almost everywhere for about $10.
