master cylinders for porsche brakes

[dgluyas]

:silly: I have Brembo 944 turbo calipers and need to know has any one used a stock 19mm master cylinder with these and did it work? I have heard a 23mm one from a 944t will work well (obviously) but some say a twin turbo one will give the right bias? Do we need to run a brake booster or will it work ok as is? I have currently 944 steel calipers at the rear and standard fronts that run well but have heard the standard m/c wont cope with the fluid requirements of the big reds? Any one got any experience?
