My 1993 urRS4 known as Da Green Monstah...
Discussion
A couple of guys have asked for da specs on my car. First off I've owned the car since new and started modifying it on day one. Since this car is so far out there, it has a lot of one-off parts that have been custom made. Its basically an Audi I-5 AAN 20 valve that has a 92.8mm crank and a slight bore to 83mm for a total of 2.51 liters. Its got a custom equal length, firing order sequenced, thick walled, stainless steel, tubular exhaust manifold. It runs 034 IIc EMS and Injector Dynamics 2000cc injectors wit a Comp CT43 billet wheel ceramic ball bearing turbo. This setup has pulled 755hp/710ft/lbs at the wheels with 36 lbs of boost and that was before the billet wheel was added. At 30 lbs with the billet wheel it started blowing head gaskets. Its got more grunt at 30 lbs than it did at 36 lbs. There's a head gasket fix coming from Sweden that should be here in a few months. For now I've got to dial it back to 26 lbs and hang on! Here's the build sheet:

Bonkers, bet it sounds good too!
It sounds absolutely sinister. The reason for the sound is the I-5 Audi configuration, the monster Comp turbo, the 3.5" exhaust from just about turbo-back, and the unique 3.5" into dual 3" rear exit. The exhaust is 3.5' until just after the rear axles and splits into dual 3.5" at the 90 degree turns. It then necks down into dual 3" sets out to the side and then mounts to 2 Magnaflow mufflers that are 3" in and dual 3" out. This video is of a preliminary run using my old 880cc injectors. We ran out of injector at 635 wheel hp. Enjoy.

king massive Turbo dude !
Amazing.Here are a few interior pics:
Sparco pedals and custom dead pedal.
Audi 3 spoke with custom perforated leather covering. A-pillar gauges are 2 5/8" boost and EGT and center is wideband AFR.
Sparco Milano seats with custom leather/Alcantara covering. WRC type handbrake to activate rear calipers.
Function switches for:
1-Arming NOS FMIC serpentine spray bar that is activated by WOT.
2-Purge for NOS onto the same spray bar. It pre-cools the FMIC for staging at the track.
3-Launch control.
4-Turns off the wideband AFR gauge for night driving.
5-Switchable maps between high boost(up) and low boost(down).
Custom gauges mounted in the Instrument Cluster.
