1970 Porsche 911 S 2.2 Targa


1970 Porsche 911 S 2.2 Targa

In 1970 Porsche offered their S model in an optional Targa body style which became the rarest model in the 911 lineup. This combined the 180 bhp race-ready package with the removable stainless Targa that was first introduced in 1967. 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.
