Did my search but still no answer for me question..

Car:
240sx, 92 KADE

Upgrade:
Front ONLY 300z 30mm

Question:
I have the calipers already but just need to find out which/type of brake master cylinder I should go with.

What ratio? 1-1/16......

Well you can run the stock master, which will be okay (I did for a while when I only had the fronts done), or you can get a 300ZX 90-95. There are slight differences in the size of the diameter. I belive the smaller the diamater the less pedal effort you need for braking.

I forgot which one I have, but on my 95 240SX I run 26mm Z32 fronts and rears along with the master, but I have ABS but changed my brake booster to a non ABS one due to turbo clearance issues. I also have stainless steel lines all around. The pedal does require a bit more effort then on a stock 240 but I dont mind. It doesnt really bother me.

This page should help you out, there is a clarification on which size/year master to run:

I'm running Z32 fronts and R33 rears with a R33 master cylinder and it works perfect for me.

I used to have a s14 silvia Q's version, and swapped brakes out with R32 GTR with the 14 BMC....and worked great.
