Won't make much difference if you haven't got the volts to go with it. Volts are what give steppers there speed.

To be honest without knowing more about what's inside I'm relutant to advise any more and suggest until you know exactly what you have and the voltages you have that you don't go messing about because it's very easy to kill these boards.

Based on expereince of these machines I think you'll find the only way to get them to go faster and be reliable is a full retro-fit with new drives, psu and motion controller the motors you can usually keep. When this is done it transforms the machine to another level, but it costs money.
