Changing speedometer max value

Hey guys.

I was thinking of purchasing a indigo glow gauge kit for my series 5 rx7 turbo. The only problem is my car is a Japanese import and its max speed on the speedometer is 180km/h. The max speed on the reverse glow gauge is 260km/h. I was wondering if anyone knows how to change the calibration of the speedometer so it shows the correct speed for the new indigo glow gauges.

cheers
