The second episode of Motorsport Retro films surrounded the creation of one very special Porsche. Let’s get to know it better.
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.
Defined 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.
On 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.
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.
Countless final details round out the puzzle, such as center lock wheels and a rebuilt G50 gearbox. We’re in love.
