This is not your average Audi S2 – it’s pushing 550 horsepower on E85, built for serious performance. Powered by a forged 2.2L 20V turbocharged inline-5 with a Precision Turbo PT5858 ball-bearing turbocharger, managed by VEMS ECU, and supported by  MSD ignition, ARP head studs, and Siemens 875cc injectors. A rare, tastefully modified, and extremely capable modern classic–ready to terrorize backroads or hit the track.
