1978 Porsche 911 SC Coupe

The 911 SC effectively replaced the 911 S and was one of Porsche’s first models that was meant for the international market. It was sold as a cheaper alternative to the 911 Turbo.

The SC used an unblown version the 930 Turbo unit that offered 180 to 200 bhp depending on model year.

Options included the rear whale tail, front chin spoiler, Bilstein dampers, 16 inch wheels with Pirelli P7 tires and sports seats. Sometimes dealers lumped these options together to create their own sport package.
