Engine
3.2L naturally aspirated flat-six (uprated from original displacement)

One of the final 20 examples of the H-series 911 coupé produced between August 1974 and July 1975, this Porsche carries a significant conversion history. Following accident damage to the left-rear quarter, it was submitted to RUF Automobile in Pfaffenhausen during 1982 for a comprehensive bare-shell rebuild to SCR 3.2 specification, gaining Turbo-style bodywork and an enlarged 3.2-litre flat-six. The original DM 30,000 invoice and annotated photographic record accompany the car, which has remained in Norway throughout its known history.

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.
