More basic questions from Mr Vauxhall Novice I'm afraid. I've putting a C20XE from an Astra into my Mini. Minis usually have a mechanical speedo drive. Seeing as the Astra has a digital dash I'm assuming the speedo is driven elctronically? If so, where is the take-off for the speedo-sensor? Is there a convenient way of recalibrating it to deal with the fact that I'm going to be running the wrong size wheels? Or can it be converted back to mechanical drive somehow?
Cheers in advance,
