I have a stampede with a photon speed motor in it and i would like to know your suggestions on which motor(as low as 15 turn)would work the best in it.It is now longer a monster truck.I have converted it to a street racer. So i need a faster motor. Something that is fast with out eating brushes.

All brushed motors "eat" brushes... that is something you can't get away from unless you go with a brushless motor/ESC. For a burshed motor I would suggest one of the Trinity Speed Gem motors. They have them available from 19T to 9T.
