words: Bill, photos: Sopt_Built via Cars & Bids

I’m a sucker for a Coupe quattro. I’m an even bigger sucker for a 2.2 turbo 5. Combine the two? Oh man. That’s what you see here. This 1991 Coupe quattro’s engine was swapped to the more desirable 2.2 turbo 5 plus it’s in that quintessential Audi 1990s color, Pearl White. Here’s the ad:

Doug’s Take

Here it is, folks: the first B3 Audi Coupe on Cars & Bids!!! It’s a cool one – it’s been swapped with a 2.2-liter turbo 5-cylinder engine, and it boasts Quattro permanent all-wheel-drive AND a 5-speed manual transmission. It’s essentially a clone of the S2, which was not officially sold in the United States, and it should be A LOT of fun to drive. It’s also rarer than many assume, Audi only sold these here for two model years. This car isn’t perfect, but the hard part of sourcing and installing the engine has already been done. It’s offered with a clean, accident-free Carfax report and the allure of no reserve.


THIS… is a 1991 Audi Coupe Quattro, finished in Pearl White with a black interior.

  • The attached Carfax history report lists no accidents in this car’s past.
  • The seller states that this Coupe’s factory engine was replaced by a 2.2-liter “AAN” turbocharged 5-cylinder by a previous owner. Some of the other modifications reported by the seller include an intercooler from an “ABY” engine, an EFI Express coil-on-plug kit, H&R Special Springs lowering springs, Porsche-sourced Brembo front brake calipers, and headlights from an RS2 fitted with HID bulbs. More information about the aftermarket parts installed on this Coupe is provided below.
  • Factory equipment includes a rear window wiper, leather upholstery, heated and power-adjustable front seats, and split-folding rear seats with a ski bag.
  • Audi released the “B3”-generation Coupe Quattro for 1990 as a replacement for the “B2” model. Based on the 80/90 platform, it closely followed the German firm’s upmarket shift by putting a bigger focus on comfort and luxury than on performance. Buyers in Europe could order the S2, which combined the 2.2-liter engine this car is powered by and Quattro all-wheel-drive, but Audi never sold it in the United States. American sales ended after 1991, though the Coupe remained available in Europe until 1997.
  • Power comes from a 2.2-liter turbocharged 5-cylinder, rated at 230 horsepower and 258 lb-ft of torque when left stock. The modifications might increase those figures but a dyno sheet is not available. It spins the four wheels via a 5-speed manual transmission and Audi’s Quattro all-wheel-drive system.

Seller Notes

  • The seller states that this Coupe has previously been repainted.
  • He adds that he performed a compression test on this Coupe. With the engine cold, the results were 145 psi on cylinder #1, 135 psi on cylinder #2, 125 psi on cylinder #3, 138 psi on cylinder #4, and 140 psi on cylinder #5. With the engine hot, these numbers increased to 148, 140, 135, 140, and 145, respectively.

So it’s not in perfect condition with a few bumps and bruises but the owner is very upfront and thorough in this car’s condition. There are hundreds of photos showing the good and the bad plus the video above. Right now, the bid is $9,400 and there are 4 days left. It’s the S2 coupe that we never got and it’s fantastic.
