911 S Guide

In 1966 the beefier 160hp 911S was introduced as the first variation of the 911. The "S" which stood for "Super" boasted performance upgrades and modifications that included larger valves, a higher compression ratio, better porting and larger carburetor jets. Along with the mechanical tweaks, the 911S also received chassis upgrades in the form of a rear anti-roll bar, Koni shocks, distinctive 5-spoke Fuchs alloy wheels and ventilated disc brakes on all four corners to replace the solid discs.

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.

The final early 911S befitted from Porsche's 2.4-liter engine the the long-wheel-base body. As such it is one of the final classic 911s before the 2.7 came out in 1973. Visually, the 2.4 range received a new chin on the front valence that was standard on the 911S and optional for the rest of the range. The S model had slight larger 6Jx15 Fuchs alloy wheels over the other models. The final early 911S benefitted from Porsche's 2.4-liter engine the the long-wheel-base body
