lots of junkers


I don't think most of the 90's non-turbo ECU's had any aftermarket tuning support, so changing the speed limiter at its source isn't an option. You could put an interrupt switch in the VSS input signal to the ECU. That will cause a code & check engine light and will make the car more prone to stalling if you coast up to a stop and push the clutch in, but it may also eliminate the speed limiter. Depends on what the default value was for a failed VSS input. Having it switchable would prevent the drivability issues, only cut the circuit when you're on a speed run.

Worth a try, the ECU's easy enough to get to under the passenger carpet and you can trace the wire from its appropriate pin at the ECU connector and cut it a couple inches back from the plug.

There's not much reason to be going 110+. Make sure your tires are rated for those speeds and are in good condition. Just saying.
