i'm interested in swapping my S5 NA power steering system for an S4/S5 speed sensing system (with the lower ratio rack, i.e. S4 Turbo).

i'm pretty sure i know what is involved (swap rack, pump, lines, computer), but has anyone done this?

and before anyone asks,

1) i want to keep power steering

2) the speed sensing system probably works better than engine rpm based system

3) i want the slight faster ratio rack

thanks.
