1978 Porsche 911 Turbo (Type 930)

9308800443roadGermany
Engine
3.3L air-cooled flat-six with air-to-air intercooler, 265 hp, 291 lb-ft torque, four-speed limited-slip transaxle
Colour
Triple black (black exterior)

A 1978 Porsche 911 Turbo (Type 930) finished in a rare 'triple-black' specification and unusual for its deletion of the factory electric sunroof, which improves body rigidity and reduces weight. Ordered new through a Boulder, Colorado dealership, the car retains its original 3.3-litre turbocharged flat-six with intercooler, Sport Seats, and Pirelli tyres. With only around 33,000 believed-original miles, no recorded accident damage, and largely original paintwork, it represents a well-preserved, single-region example accompanied by a Porsche Production Specifications certificate and two decades of supporting documentation.

Are you the owner of this car?

This car's public record is built from its auction and competition history. Register your ownership and privately add your own records to make it a verified Legacy Metrics passport — provenance that backs your car's value at sale and gives your insurer evidence to price against. Roy reviews and verifies every registration personally.

Each chassis record is compiled from public auction archives and links to its source material. Ownership, competition and maintenance entries are extracted from those catalogue listings by an LLM, which can make mistakes — please contact us with any corrections. The summary is Legacy Metrics’ own writing; we do not reproduce catalogue text.

“Full” and “partial” documentation labels indicate how well each entry is corroborated in the underlying sources, not an audit of the car’s physical paperwork. Names of recent or living owners are withheld for privacy.
