3.6L-Powered 1977 Porsche 911S Coupe

This 1977 Porsche 911S Coupe is a US-market example that received a major service in October 2025 totaling ~$69k, which involved retrofitting a replacement 3.6-liter flat-six, installing a performance exhaust system with Dansk SSI heat exchangers, modifying the wiring harness, resealing the five-speed manual transaxle, replacing the fuel tank, and more as detailed below.

The car is finished in metallic green over tan leather upholstery and also has a sunroof, a driver’s side mirror, a front strut brace, and 15” Fuchs wheels.

This mid-year 911 was acquired by the seller in 2020 and is now offered in Canada with 2025 invoices, the removed factory engine, and Alberta registration in the seller’s name.
