thanks a lot
there's one more thing i just thought of.
have you ever heard of a brand named PN racing?
they made a motor that was faster than the xspeed called the Speedy motor. it requires no turbo esc upgrade, but it sometimes burns the board on the MZ. i was wondering if you have ever heard of something like that and if it can be prevented when using the motor.
i personally have witnessed a board fried by that particullar motor. it didnt fry the board at once but after many runs my friends Z just stopped and it had a distinct odor. i really recommend installing a turbo. this will protect your Z board and give your car hella torque!
