i've faded ever kind of brakes there are, even brembo's. how u set them up is mroe important than what kind they are. pad/fluid selection will do more for pedal feel than even a master cylinder. q45/j30 is better imo than z32 for s13/14. unless you are going to use complete z32, which means fronts, rears, and the master. a set up like that feels good and works good.
