From what I have read in the past...
The 15/16 MC off either an automatic 240sx or z31 non-turbo is just about perfect for z32 front brakes with stock rear brakes.
The 1" MC from a z32 is best for the full brake conversion.
The 17/16 MC is the biggest, and gives the firmest pedal feel with the full brake swap.
These master cylinders bolt on to s13's with ABS, but non-ABS cars require you to take out the middle screw and replace it with a fitting for one of the brake lines, iirc.
