You'll see the return the moment you shift gears. The modern synchros of the G50 are a night-and-day difference compared to the 915/930 synchros, allowing smoother, faster shifts with very positive engagement.

Now let's talk clutch:
It's easy for a lightly modified Turbo engine, one with the standard bolt-on upgrades, to over-power a 915's 225mm diameter clutch. A clutch with enough clamping strength usually results in a very still pedal, difficult to modulate: high clamping force pressure plate, metallic disc.
With a G50, you get a 240mm diameter clutch. More clutch diameter = more surface area = more grip, more torque capacity, even if the pressure plate has the same clamping force. There are several aluminum pressure plates and organic, spring-hub discs available to match up to an engine's output. And even with the strongest pressure plate, the pedal effort is reduced thanks to the hydraulic clutch release mechanism -- no more clutch cable.


No, a G50 swap is not inexpensive, but it is utterly transformative.
