I was reading the archives and i was wondering what the size is for the 1982 turbo zx master cylinder. is it the 15/16 or 7/8? i put this on my 240z when i did my brake conversion, and i wanted to check this out because i think im going to need to change my brake booster soon. any suggestions on which booster to use with this master cylinder. is there a better combo to use? i currently have the 4X4 front vented brakes with the 280zx turbo rear disc brakes. thanks in advance.
