I decide to do a project thread of my UrS4 now when I have been familiar with this forum.
I bought the car last summer and it was one of the cheapest ones that was on the market at the moment. It is a 6-speed and hade done 275k km. It had a "bigger" hybrit turbo, stainless china tubular exhaust manifold and MTM-chip. The owner told it should have ~300hp. I think maybe 270-280hp was closer to the truth. Commonly the car was in quite sad shape. Scratches and rust here and there, bumbers was hanging, boost was acting strange, turbo oil-lines was leaking oil(almost catch fire ones ) and there was some electrical problems also. The central locking didn't work and the insrument cluster had several issues, light check control and brake pad check was alerting... etc. etc...
This was the look when I first got it home:
After some close investigating I finnally found someting positive. Did know there was Weitecs lowering springs, but there was also Koni yellow shocks all around, and they was in good working shape.
Well, few hours with the soldering iron resolve all the electric problems...
Central lockin pump looked like this:
...and after maintenance:
Have workt fine since.
The insrumen cluster did also get full overhaul:
Also the light check modul did get a small mod...
Soon it was time to get some more power, I had the feeling the engine run lean on upper rpm's and I did not want to destroy it, so bigger injectors, a 3bar map and Walbro 255LPH fuel pump was first on the list.
Before remapping I also bought a 76x300x400 IC which I put in serial with the stock IC. Not easy thing to do. There was almost no space at all behind the bumper. Had to move the radiator 20mm backwards and give the bumper a lightening cure.
It's also good to approve the air flow for the stock IC with a B5 S4 inner-fender grill:
