agreed on the $$$ making it fast. to make serious power you have to put rods in it, and these motors don't rev high so i don't see the sense in putting a big turbo on it without building the head. the turbo is actually a subaru turbo lol...probably around a gt28r or possibly disco potato size if i had to guess?
oh and the car has the oettinger kit on it too...i looked long and hard to find this avant (got it from canada actually). i got an avant for the same reasons u said...timeless looks and u don't see modded audis often, much less avants.
