The mid 1970s are sort of the forgotten years for Porsche in the U.S. (or at least the years Porsche wishes they could forget).
Ever-tightening emission control laws played havoc with engine longevity from 1975 until 1977. Unbelievably, Porsche s answer to smog regs was heat. Thermal reactors burned exhaust gasses and they even removed some fan blades to raise running temperatures.

Experienced Porsche engine builders can fix these issues today, but not if the car still has to pass smog tests. It s a bit of a moot point anyway as few 1975-77 911s seem to have survived.
The standard 911 model had a flat-six engine with a displacement of 2.7 litres. This initially developed 150 hp and 165 hp as of MY 1976.
The engine of the 911 S delivered an output of 175 hp.

I traded my Karmann Ghia for this 911. I really enjoy driving this 911 BUT...
No 3 points seat belts at the back. So no way to have a car seat for my daughter"
I sold this car on ebay to a french Gentleman. The car was sent to France and he did a full body/Paint resto (car was repainted in green)
However the engine blew few months after :-(...
