I have a 1991 Honda Civic STD, I am converting it to disk in the rear, I am using 1993 integra LS trailing arms etc. and and putting larger disks up front, probably use the knuckles and rotors etc from a 1996 Civic EX, what should I use for a master cylinder, will the STD one work, or should i switch it with another one, if so, which should i use, i also have a MC from a 1988 CRX Si, i'm not sure if this will work either i just had it with some spare parts. Any help would be great thanks

 

88 crx si master is probably the same as what you have. only the 90-91 crx si had rear disc. i would just change out the proportioning valve to the integra model first and go from there depending on what your pedal feels like.
