What are you doing to the brakes to necessitate the bigger master cylinder?</TD></TR></TABLE>
I thought the Integra has 15/16? Oh well, it's one of those

If you are doing a rear drum to disc swap and keeping your front brake calipers the same, you do not need to go to a bigger master cylinder; the rear wheel cylinder on the drums take up about the same fluid volume as the rear disc calipers.
Now, you may find that you will have to switch out the proportioning valve.
Once you upgrade the front calieprs, get the bigger master cylinder.
Otherwise, keep 'em drums in the rear, get good fluid and good pads for the front and solid/blank rotors, new shoes and drums in the rear and you're good to go.
A trick is to engage the parking brake a couple clicks while auto-xing or road racing to get the shoes closer to the drums so you will have better pedal feel. Remember, the fronts do about 70%-80% of the braking on our FWD hondas.

If you do a rear drum-to-disc swap and leave the fronts alone, you just need to swap out the prop valve. What model/year is your car? For the EG, you'd swap from the 30/40 to the 40/40.
For the EK, youd swap it for a 99-00 Si valve, although, if you were to compare part numbers, you'd find that the 99/00 DX prop valve is the same as the 99/00 Si one. So for the EK, the prop valves are the same. You could swap in the 99/00 Si master cylinder if you wanted to reduce the slight additional pedal travel from going to disc from drum.
And I'd like to correct myself, the 99-00 Si coupe actually have a 7/8 m/c;
the DX/CX have a 13/16.

If you are not changing your front brakes, you don't need a new master cylinder. Just make sure to bleed ALL the air out of the lines before you drive. The pedal should be rock hard like it was before.
***IMPORTANT***
All 96-00 hatchbacks have the same proportioning valve as 99-00 Si, so there is no need to worry about changing it out. If you don't believe me, check part numbers at hondaautomotiveparts.com. Nobody knows why Honda did this, but you should just leave that part alone...
FYI: 99-00 Si has 7/8" master cylinder (same front calipers as EX & Del Sol VTEC)...

Only the HATCHBACKS have the same valve as the Si!

I just checked slhondaparts.com and they list the same propvalve part number for the DX coupe and the Si coupe, model year 99 or 00.

It took me two hours to do a MC and booster swap, and that includes bench bleeding the MC and bleeding all four calipers. Now if you don't want to swap out the booster the 98-01 MC will still bolt onto the stock booster.
