I am just starting to kick around the idea of moving from my passat to a 2001 or 2002 A6 2.7t or a 2001 s4. I am only looking at 6 speed, and I am not looking at anything with more than about 45K on the clock. Was wondering what you all knew about used 2.7t engines and would I be getting myself into a nightmarish relationship. I am quite sure the urge to chip the car would overwhelm my sense of self control. In other words, I would chip it. No other engine mods would be done. Thanks for your opinions. I'd love to get a new a6 2.7t, but It's just not "fiscally responsible." Even if it was, I don't think I could afford it anyways.
