1973 Porsche 911E LWB

This Porsche 911 RSR Tribute is a remarkable lightweight ‘restomod’ build by renowned specialist Corse Automotive. Under the decklid now sits a 964-generation air-cooled 3.8-litre flat-six, rebuilt and tuned to send 270kW (360hp) to the rear wheels via a close-ratio 915 five-speed manual transmission and Modena Motorsport limited-slip differential. The 1010kg curb weight and uprated engine equate to an impressive power-to-weight ratio of 2.8kg/hp. Project ‘Enigma’ is based on an Australian-market 1973 Porsche 911 E shell, and Corse Automotive’s extensive programme of restoration and conversion included chemical dipping the bodyshell, subsequent bodywork and a bare metal respray, uprated suspension, braking system, drivetrain and engine, and a bespoke interior retrim by SRK Customs. The car has been with its enthusiast custodian for around nine years, and is fully road registered in NSW. This Porsche was most recently serviced by specialist Corse Automotive in September 2024. The five-digit odometer shows 6,500Km, having been reset to zero at the time of the extensive ‘restomod’ build. ‘Enigma’ is finished Mint Pastel with contrasting matte black Carrera side stripes and rear Porsche script, over a bespoke black Alcantara-trimmed cabin, punctuated with a body-coloured transmission tunnel and red contrast stitching.
