save yourself the headache and get a matching mc/bb set
however, as long as the flanges match, you should be fine

didnt you ask this before?

 

i know i need a non-ABS master cylinder and booster, and i was planing on buying a new master cylinder for a type-r at honda or autozone since the one in my project car (13/16"s non abs) is bad and leaky. and someone near me is parting out an RS integra (15/16" bore) just want to know if i can use that booster and a new itr master?

 

like i said, save yourself the headache and just get a matching set
unless you have integra calipers, a 7/8" from an ex/si is plenty large enough

 

i have an ex civic but a 13/16ths master could that be the cuase of my leak??? smaller master cylinder on a bigger booster?

 

If this is for a 92-95 non abs just use the 15/16" 91 civic ex sedan master cylinder. It will match up with your brake booster and existing lines. 1/16" under a full inch and 1/8" more than what you have already with or without a 40/40 prop valve will give you a better pedal feel and bolt right up.

This is just my suggestion otherwise good luck.

 

96+ are 7/8
I would just do the above^

 

ya i have the 40/40 for the rear disc swap ill go check out that 91 ex sedan one ty for the info

 

i have a 94 ex with abs and was wondering about a type r master cylinder can i just swap master cylinder for a type r w/abs or do i need the booster also
