1973 PORSCHE 911 CARRERA RS – Outlaw
For sale is this viper green, right hand drive 73 Carrera RS Outlaw, nicknamed the “The Green Mamba”. Weighing in at 1,000kg and delivering 290 HP, gives this car an impressive power-to-weight ratio for a normally aspirated 50 year old car (the original 2.7 RS made 210hp).
It was recently brought out of retirement where it was part of a collection of rare cars in a collector’s man cave since 2005. It received a mini restoration with a complete respray, a ceramic protective coating was applied, new decals, brakes completely rebuilt, Weber carbs reconditioned and thorough service was done.
This unique 911 was built in 1994 by Peter Gough, one of the most respected and legendary racing drivers in South Africa. At the end of his lustrous racing career, he started building RS and RSR recreations. He even raced some of them very successfully. Peter aimed to build a normally aspirated 290 hp car weighing in at 1,000kg, which he achieved using a 1981 3.0 SC engine, increasing the capacity to 3.2l and fitting a 930 crank, RSR cams and a performance exhaust. Fuel delivery is handled by 46mm Weber carbs and twin spark takes care of the ignition. This winning recipe created a high-revving flat-six engine that sounds amazing when hitting the higher RPM range. The power plant is mated to a 5-speed 915 gearbox.
The donor car was a rare 1972 911T RHD, sprayed in the original Viper Green No255 used in 1973. It is an all-metal car and the rear RS metal fenders were welded in. Ducktail and bumpers are lightweight fiberglass. Some parts were deleted and even with a full roll cage the weight of just over 1,000kg was achieved.
To be glued to the road this lightweight 911 sit on original 16” Fuchs wheels and H&R coil over racing suspension were fitted, supplemented by oversized anti-sway bars. Shaking off speed in a hurry is handled by Porsche 928 brakes that were completely rebuilt with new pads. The brake system was upgraded using dual brake master cylinders and the brake bias can be adjusted from the dashboard.
To keep the weight further down Carbon fiber lightweight Corbeau GT Seats were installed with red 5-point harnesses for safety. Steering this special 911 is done with a Momo MOD.07 steering wheel covered in Grey Napa.
In 1998 it caught the eye of the then South African Porsche Club’s chairman and he bought it from Peter Geoff. He entered the Porsche into many competitions including gym kana events, time trial events, show car competitions, some races, and even a drag race or two. He won over 51 trophies during his ownership. A full list and details of the trophies are available on a dedicated website with the link below. He sold the car in 2005 and it stood as part of a collection until now.
