I found this Brazilian guy that has done some seriously awesome mods, from adding paddle shifters to converting display cluster to hid conversions... His car is a Jetta sportwagon, but the vac-com adjustments should be the same, and most of the physical mods should be very similar as well. Minor tweaks may need to be made sure to form factor differences, but very informative stuff...
