Audi UrS6 Quattro 2.2t

The Audi urS6 Quattro. 3800lbs. AWD. The engine is an inline 5 cylinder with dual overhead camshafts, 20 valves, a k24 turbo and a front mount intercooler running 20+ psi of boost. The result? Three hundred horsepower.

As a luxury sedan this once 45,000$ car shines. Quality materials and engineering are at every turn. Many of the parts from this car were later used for my own A4 Quattro. The S6 is luxury car delicious. Automatic climate control. Huge leather, well bolstered, heated, infinitely adjustable seats. Front and rear fog lights, a dash mounted ignition, a thick solid steering wheel, and an easy to read, attractive, assortment of gauges. Since its purchase M and I have gone on multiple road trips and this is where it truly shines. Miles are dispatched with a vengeance.

23psi manifold pressure over ambient is a lovely place to be if you ever get the chance. M didn't really ring it out for the test drive (on unknown roads) but coming out of a toll booth on the way back 2nd gear was exploited to its fullest. The resulting explosion of engine and exhaust noise was deafening from my A4 chase car.

  6. Brake fluid flush, twice so far.
  7. Carputer, inverter, amp, Infinity speakers, and OFC wire.
  8. Weight reduction: misc screws, stock amps and speakers, stock HU and phone, the manual crank for the sunroof.

Shifter

shifter

The stock shifter in the S6 has good action and is mechanically satisfying but the throws are way too long and have a spring loaded effect that can be disconcerting. The stock piece is half plastic and has enough play inherent in its construction to be irritating. M replaced it with an exquisitely made unit from 034 motorsports pictured above. I wish I'd had this piece long enough for a good photo shoot with it!

The plastic piece in the top right is stock.

cup

The cup that the shift lever pivots from. It's mounted in that rubber piece which surprisingly doesn't add any slop to the complete mechanism. However there are several things to address. The lever itself is two pieces and they are not a perfect fit, presumably to make room for grease and to facilitate the push down reverse. M wants neither the grease nor the push down reverse so a permanent fixing of the shift lever itself will be in order. The other slop is at the transmission where there is some kind of bushing. We haven't had it apart yet but there are ways to fix it.

shifter

This is a must buy for this car in my opinion. For me the interface always makes the biggest difference when it comes to repairs and modifications. So far on this car all have been addressed in some way:

doord card

Here is the fabric insert removed and re- covered in synthetic suede. You have to drill out multiple plastic rivets and pry the glued panel apart to get it out but they are flat making them quite easy to get the fabric onto cleanly.

door card 2

Finished product after cleaning the door card and gluing the panel in. The trim will be painted and installed next. This is a good opportunity to emulate the s6 plus if you are so inclined. Several online retailers sell synthetic suede by the yard. With two yards we had enough to do four doors, shift and brake boots and almost the headliner.

After some testing we realized that the super crappy intercooler that came on the car when M___ bought it was leaking probably since forever. In an effort to reduce the number of vacuum/boost leaks he replaced it with a nice bar and plate unit.

When we were taking the old, frayed stainless brake lines off of the rear hard lines the fittings at the hard line twisted off. One brake tubing bender/ flare tool later and it's as good as gold. Maybe we'll get to use it on the fuel lines one day?!
