There are many, many rumors about Tamiya motors for a Mini-Z. Yes, some will work but, others will cook your ESC. This happens if the current (mA) being drawn from the motor is above 1.5A or 1500 mA. The safe range is 1.0A ? 1.5A.
Of course, if your are using FETs or a turbo, a higher amp draw is allowed.
