3.0L turbocharged air-cooled flat-six, four-speed manual gearbox

A 1977 Porsche 911 Turbo (930) originally delivered new in Germany before spending a substantial period in the United States. Presented in ostensibly original condition, the car has accumulated fewer than 4,000 kilometres since a comprehensive mechanical rebuild carried out in the Netherlands in 2015 at a cost approaching €46,872. Equipped with the turbocharged 3.0-litre air-cooled flat-six and four-speed manual gearbox, it retains the characteristic wide-arch bodywork and whale-tail spoiler of the early 930 series.

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.
