Not neccesarily.
Also depends on how much torque the motor develops (varies on brand/wind), your gearing (what can the motor/ESC handle before you fry it), battery choice (both voltage and max current) and the ESC (how much current it can deliver, will it run boost or not, is it sensored or not).
The 2000/2250 is just the rpm/volt rating. So (theoretically) its just the top speed. If you are on a circuit, the nominally slower car may be quicker as it can change direction/accelerate quicker, but on a bigger circuit the faster motor may come into its own.
FWIW, you can pick up 1/8th scale motors from places like giantshark and hobbyking for not very much.
