get a master cylinder from a z32 300zx. There are a few different ones as far as size goes but any will be a major improvement over what you have. You are currently trying to move four times as much fluid with the same master cylinder. When you upgrade you will see that the 300zx m/c comes with a plug in one of the holes. You will have to remove it and from the old master cylinder you will have to carefully cut out one of the brass seats and install it into the zx m/c. Other than having to pull and bend on the lines a little because one of the lines is on the other side, it's a straight forward swap.

you only have to remove the plug if you use an ABS MC on your non-ABS car. I know, I've done it. I went with the 300zx 30mm brakes upfront and rear and the 300zx 1 1/16" (17/16") Master Cylinder. There are plent of MC's on ebay all the time.
