All 17.5 turn motors do have 17.5 turns (the wires inside the can) many other factors come into play to determine the kv rating. Manufacturers usually provide this figure.

Kv ratings and torque have more to do with each other in a visa versa sort of way; as kv goes up torque goes down and visa versa, kv down torque goes up.
