Well you have not supplied much context to your question, but I will try to offer what I can.
The NB Turbo S is the "GTI" of New Beetles. So while it has some bits that could be considered an upgrade for your regular Beetle, these parts are not exclusive to the Turbo S.
It will have:
larger front brakes
stiffer springs
bigger sway bars (the rear is part of the beam)
All that stuff can be found on later AWP GTIs and GLIs, too, as well as some VR6 and non-GTI/GLI AWP models.
The NB Turbo S *might* have HID headlamps, these were a rare option. Personally, I would never want them, but....
They have larger wheels that are exclusive to them.
Anything else is cosmetic: the bumper covers for instance, and they have the rear hatch spoiler (most all AWP NBs had these). The front seats are more the bucket type.
They have a 6sp manual, but it is not geared appropriately for the TDIs.
