1970 Porsche 911 S 2.2 Coupé

Along with all the C-series improvements to the 911 line, the 1970 Porsche 911 S was upgraded to include a 180 bhp version flat-6. This further improved the performance credentials of the model which already had Fuchs light alloy wheels and bigger brakes.

Specific to the S model’s engine was a re-profiled camshaft, larger valves, better porting, higher compression and larger jets for the Weber carburetors. This resulted in 30 more horsepower for a total 180 horsepower and torque slightly improved. Redline was raised to 7300 rpm. Porsche fitted an ignition cutout that interrupted spark to the plugs near maximum rpm. One peculiarity of the 911 S was its lack of choke which required accelerator pumping for cold starts was usually enough for starting.

Chassis upgrades included a rear anti-roll bar, Koni shocks and ventilated discs which replaced the standard solid rotors. For the S, special gear ratios were installed in the five-speed transmission including an overdrive in 5th gear. The higher ratios allowed for 0-60 in eight seconds.

1970 Porsche 911 S 2.2 Coupé

1971 Porsche 911 2,2L S 9111300566. The Porsche 911 S on offer has a wonderful history. It was bought in 1982 by the Archambeaud family from the first owner, to remind them of the 1960s/70s when they had created the racing team ” Archambeaud Racing “, responsible for running numerous cars including Gordini, Renault prototypes, Lola T70 and 212, Porsche Carrera 6 and 911…

When it was bought in 1982, this 2.2 S was in original condition, having been maintained at the time by a friend of the family, the famous preparer Louis Meznarie. Mr Archambeaud’s son took the car on in 1991 and decided to return it to its former glory during the 2000s. Fully restored in the family’s workshop, the car has kept its initial colour, ” Sepiabraun 7474 “. The rear bench seat, in good condition, is original but the Recaro seats in the front have been refurbished by the Établissements Caribex, which has returned the car to the remarkable configuration it was in when first delivered. It retains its original engine, which has been well looked after. Since then, the car has been regularly maintained by the specialist Special Auto Dechaumel. Auction Source: Rétromobile 2015 by Artcurial Motorcars
