Is it possible to change the instrument clusters in a car? (ie,
Speedometer)
If possible, i intend to buy a COE 200SX s13..

Yup, it's possible to change the whole instrument cluster. IIRC,
for the S13, there should even be a Nismo speedo for the S13,
though it will not be easy to find nowadays..
In addition, parts for the CA18DE will not be easy to find
also.. Think maintanence may be quite jialat
