RE: Motor Swap
No you'd cook the motor.
You would need more than a 2 watt motor to move this car, to give you an idea of power required...
750 watts = 1 hp
I think you should be looking at a brushless motor and ESC combo that runs on 18.4 volts and can carry a lot of watts.
Ask in the car & truck forums they would have a better idea of wattage needed.
