23 mm Master cylinder?, From a 930? Options

[HalfMoon]

A friend of mine who owns a race shop that does alot of Porsche work said when queried about reducing travel on the 914 brake system that the 23mm master cylinder from a 930 would far better reduce the travel over a 19mm master cylinder.
Has anyone done this mod and if so, what were the performance gains/differences?
Thanks

And, important to note, with just a larger m/c your brakes will NOT have any additional braking force, the car will stop exactly the same, brake fade will be exactly the same, the pedal will simply be harder to push.

I come from sport bikes. Have you seen them do stoppies, a wheelstand on the front wheel while braking? Requires a HUGE amount of control to keep it right on that edge, and the only way that's possible is with modulation, i.e. a long lever (or pedal), which is the exact opposite of what you get with a larger 23mm master on the same calipers. Nothing's free, so with a harder pedal and less modulation what you give up is control. You have the same amount of brake so you can still "go through the windshield" but it's more binary, on-off, and that's not usually desirable. For me, anyway. Tastes differ, as always.
