Bigger Master Cylinder, Ideas? Options

[Bigmeanbulldog55]

Well, since I've done some stuff to my car the stock clutch doesn't want to hold right anymore. It still holds, but it won't if once I finish. So, as a preventative measure, I want a bigger master cylinder to disengage my stage 3 clutch. I had it in for awhile, but the stock master cylinder wouldn't open it enough to switch gears super smooth. So I took it out and put a stock back in. Now I want it us it, but I have to get something to make it work. So, for you gear heads, what can I do? How can I increase pressure to the slave cylinder and make this clutch work. This might be a nice brake upgrade too. Let me know guys. If no one has any ideas, I'll just go yank one off a Tacoma and see how close it is.

well....
brake fluid designations just indicate the boiling point of the fluid, since the slave cylinder doesnt get hot it wouldnt matter at all what kind of brake fluid you put in the clutch system.

boring out the master isnt a good idea, you'd have a hell of a time finding pistons, springs, and rods to fit it, and the inside has a special finish which is very hard to reproduce.
