Gauges are calibrated to work with their specific senders.
If you want to use the miata cluster, use the gauges that came with it.
There are gauge skins you can buy in different colors and styles to make the gauges appear different.
I believe some year models (96?) had a fake oil pressure gauge controlled by the computer.
What ever gauges you select, make sure you get the sender/sensor.
With the miata fuel level sensor, you need a miata fuel gauge for the calibration to work.
