FOR SALE is my 1995.5 Audi URS6, my pride and joy. My build on here is 1995.5 URS6 EFR 7163 w/ QSV- FOR SALE in the build section.

Fully built 2.2L AAN with ceramic coated internals from Swain ($8,000+), Iroz twin scroll manifold (.84A/R) Borg Warner EFR 7163 turbo, twin walbro 044s in custom ...

All, I never thought this day would come, but I have decided to sell my beloved ur-S6. I would like to sell it on here to someone who will respect and use it as I have, with lots of love and throttle.

I am asking 39000 OBO, you can see the build on here.

I am buying a house and unfortunately ...

Well, it has been an interesting summer with the S6. When I took it to the track, the front rotors cracked. I was able to track down the original builder of the car in 2000 to find what the rotors were on the car, they are custom 2 piece rotors made for the Porsche 993TT calipers. The company that ...

Great job Jeff, I pray there is video and sound. Pretty cool see a 25 year old car spank an R8! Jeff, you are our hero.

Good numbers, but wait until we add 10-12 lbs of boost! @mushasho, yes, the load on the street is different so spool is much sooner. It normally isn't 1000 rpm, but anecdotally yeah, boost hits closer to 3500 than 4000 for me on the street. I'll eventually re-dyno it when we turn everything up to ...

Matt,

It was a blast at the track. I had Cooper Zeon RS3-As on which are an all season leaning summer tire- it was not ideal in the dry, so Toyo R888s for next year. In the wet, they were awesome- I was still able to his 125 on the straight and not hydroplane like everyone else... I've attached the ...

Well,

I finally took the S6 to the track. What an experience. First, I'm putting Toyo R888 on next time. I was at Grattan in Belding, MI, a fairly small track for this kind of car. The car performed flawlessly other than I cracked my right front rotor (as I got home from the weekend 2 hours north ...

Looks like a fun build! I second the tradeoff for spool. Unfortunately, we don't live where there is an autobahn so most of our fun is getting up to the speed limit(ish). For 340wheel, maybe a gtx3076 or the equivalent? Although I"ve heard that compressor is mismatched... I wish you luck!

For anyone curious about the clutch:

It has been installed and is in its' break-in period. The pedal effort is not much more than the stage 1 that was in it before. The engagement, however, is very touchy, but that was expected. The friction zone is very narrow but hey, this is a stage 4 extreme ...

Just replaced these parts through Marc after removing trans:

SO epic! Makes me feel bad for not putting the locking diff on the urs6 to use in the winter, rather using the open diff of the b6. They get around great. Does anyone have input on how the new haldex cars do vs the older torsen ones? This is such an awesome build! I'm in Northern Michigan and we got ...

Say, for example, you found a cat wandering on the street. You take it in, give it some love and eventually you find out that it already has a home. The right thing to do is give the cat back. /endmetaphor

Imgur won't upload anything, unfortunately.

Here are some photos of the air intake. Front of air intake touches front of right front fender well, goes up towards turbo and hooks around to front of turbo. Apologize for bad photos but using a manual focus Leica in one hand and flashlight in the other in a dark garage proved to be a challenge ...

UPDATE:

I have purchased a South Bend Stage 4 Extreme clutch (full face, cerametallic), Sachs 707pp and Fidanza LWLW through EFI Express. We are currently testing to see if Shrick cams will clear stock pistons and if they do not, I will be in a tight spot to see if I am going to replace my pistons ...

@Herbehop, always confirm with the expert but I believe boost pressure. We have a built in safety that if the exhaust backpressure exceeds 30psi the valve opens. I will say, the induction/turbo noise with the QSV is really different and sounds awesome! You can hear the change in induction noise when ...

Marc put my Apikol FMIC in for me and it fits like stock- just two small slats need to be cut into the lower bumper but any specifics he'd know about. They aren't terrible to put in from what I have heard. He would be the one to ask, EFI Express is his business. I have the same kit with the 7163 and ...

Thanks a lot- will that clutch setup fit an aftermarket Fidanza aluminum flywheel?

Thanks, that makes sense. Didn't even think of that. Next putting in cams and a new clutch. I know you said Sachs 707 pp but I couldn't find a clutch that met your suggestion, Jim. If you had a link that would be great, looking for street driveability and ability to hold 500wtq.


Thanks!

Since the new EFR has been put on, the exhaust is much quieter. I have some magnaflow muffler (not sure which), no cats, no resonator. 3" turbo back. Any suggestions for mufflers that are loud but don't drone? I would be okay with some drone if it was louder. I miss the bass of that fifth cylinder ...

Crazy how once you open up this can of worms you never run out of things to improve upon. As my fuel gauge was being looked at, we realized that 93,94,95 and 95.5 C4s have NO rear sway bar, so I have ordered a rear sway bar kit from Apikol, who also did my FMIC. Going on next week.
