I think people don't appreciate this, but back then 165hp -- the rating on a '77 911S -- was nothing to sneeze at. Even into the 80s, sports cars had horsepower figures that are today pretty quotidian; the first gen Nissan 300zx had only about 170hp in the normally-aspirated version.

A 2022 Kia Optima -- ie, a fairly bland sedan -- his more horsepower than that.

By the 90s the numbers were getting higher. The Porsche I had the longest was a base model 1995 911 (so a 993; last version of the air-cooled cars). It had something like 270hp, which was reasonably serious for the era.

The current base-model 911 is something like 380hp if I'm not mistaken.

My car was loud, rattly, and smelled like oil much of the time. The interior "domestication" that eventually came to the car was still a generation away, so my car was more like a VW Bug inside than a modern luxury sports car. Driving it was a MUCH more visceral experience than driving a newer car, though. I stopped driving it regularly and ended up selling it when I realized what it was worth (damn near what I paid for it), but it was a great car.

The new owner put some money into it and is having some success at autocross. I get visitation rights. :)
