Master Cylinder upgrade

Ive got a 91 RT and am looking to do a huge brake setup on it for future time attack events and so forth. I picked up some 05 Acura RL front calipers and am working on the rear setup but need to change it to disc brakes first. My real question is a master cylinder upgrade. Id like to go with a 1 inch bore but it seems difficult to find one that is a direct bolt on. I know about the 15/16" masters that can be used but I'm looking to go bigger in order to fill these massive calipers with enough fluid. Anyone have any suggestions?

...and the GSR is a 1" 2-port MC already.
EDIT - 12/16 -
I do remember having to replace the fitting on the brake line that is moved with the fitting from the master cylinder. The ID is the same, but the OD is bigger.
After reading this I did some checking, and apperently any Master Cylinder on any 98+ integra (Excluding the RS model) had a 1" bore.
Edited my post above, as I remembered I had to swap fittings on the line that was moved.
Haha nah man wasn't hinting at that at all. But found it interesting that a 98+ Type R MC is around 100ish, while a 98+ GSR MC (which is the same bore) is around 80ish.
Yea I did this swap my self, since I was sticking with drums in the rear. The only "mod" I had to do was slightly re bend one of the brake lines, but nothing I couldnt do with my muskules.
Slotted Rotors
Upgraded Pads
Braided Brake Lines (While we are at it, are the lines the same for all civic's?)
and this 15"/16" MC
Any opinions on this set-up would be great! My brakes are ready to go, I need this done this week! Thanks!
for the master cylinder, the 15/16 comes on many models. Preludes, accord LX-i and SE-i, 88-91 Civic EX, probably more.
For the master cylinder I don't know if ebay is the best route if its a made in Taiwan type of deal.
If you are just added slotted rotors and nice pads I don't think the 15/16 is absolutely necessary. If your MC is bad and you are replacing it anyway that's another story.
For the stainless lines, Earls and Goodridge seem to be the most affordable brandnames. You can get them on Amazon.com or Summitracing.com. If I remember right, for a wagon with rear drums you would want to get ones for a Civic sedan 4 door. Some one with more experience can chime in on this, I just know they need to be the right length and not be for rear disc applications.
