So you have a Z31 Turbo and just can't get past the crazy speed of 137mph. Well this is because Nissan installed a speed limiter in the ECU of all Turbo Z31 models shipped to the USD Market. Non-Turbo models did not have this feature in the ECU therefore they are only limited by power.

If you wish to remove this limiter it isn't hard to do. You only need to disconnect the speed signal to the ECU. This is done by Cutting the wire that feeds the signal. The Wire is a Purple wire going to Pin 29 on the ECU.
