Master Cylinder, Sive Matters?

I have a chance to swap my brake system(93 sentra E)to 93 NX2000 set-up,now would I benefit from or need to use the brake master cylinder too. info appreciated!

you do not need a bigger MC but it might help somewhat
though dont go too big or it will overload the brakes and cause overheating or early lockup (especially without ABS)

swap on the brakes and if it feels like you have to push too hard on the pedal to get it to work then swap MCs

thanks,will try.
