Gallery: Up close and personal with the 911 Group 4

Submitted by on December 16, 2013

911 Group 4The second episode of Motorsport Retro films surrounded the creation of one very special Porsche. Let’s get to know it better.

wd40-4 If you’ve watched the film already you’ll likely agree that the Autohaus 911 Group 4 is a stunning piece of machinery. Inside and out, from top to bottom, it pays beautiful homage to one of the coolest 911s ever.

wd40-111Defined by the unmistakable aggression of those 911 SC Group 4 bolt-on wheel arches, the body features the full kit with matching front spoiler, rear ducktail and 935 mirrors. The car itself started life as a factory right-hook 3.2 Carrera, and has been refinished in the original GP White.

wd40-13On the inside it boasts Alcantara trimming, a Momo wheel, RS carpet, carbon seats and a host of killer touches which bring it in line with Group 4 specification. Since completion, Autohaus have gone to the effort of eliminating typical rattles and squeaks.

Group 4 engine The engine has been pulled down and painstakingly reconstructed to the finest of tolerances. The blueprinted assembly is now decked out with a 3.4L piston and barrel set, custom ground camshafts. Turning over with a cranky 10.3:1 static compression ratio, it runs purely on 98 RON premium unleaded fuel thanks to a remapped Motronic engine control unit.
