The m/c really doesn't replaced unless you go to a larger set of front calipers. Just change the prop valve to the 40/40.
The SI civic, and Integras have that valve.
The larger m/c for EX civic from around 90 up or preludes will interchange, and some are 7/8 and some are 15/16.
For the EX front disc you need the 7/8 and for the larger caliper Integra, use the 15/16.
