About the Porsche 911 Turbo (930)

The Porsche 911 Turbo (930) is the definitive poster car that introduced turbocharging to the 911 lineage, produced globally from 1975 through to 1989. Originally born from Porsche’s motorsport ambitions, the early 3.0-litre variants (1975–1977) delivered 191kW and were famous for their demanding power delivery and four-speed manual gearboxes. From 1978, the engine grew to 3.3 litres and gained an air-to-air intercooler—necessitating the shift from the "whale tail" to the larger "tea tray" rear spoiler—which bumped output to 221kW. In the Australian market, the 930 is an incredibly exclusive collector piece; only 41 of the 3.0-litre cars were officially delivered locally, with the 3.3-litre models also arriving in very limited numbers before official imports ceased for a period in the mid-1980s. The buyer pool is most aggressive for the final-year 1989 models, which finally received the five-speed G50 transmission, transforming the car's driveability and securing its status as the most refined evolution of the original Turbo formula. Desirability remains at an all-time high for Australian-delivered, matching-numbers examples, which command a significant premium over personal imports due to their verified local provenance and documented histories. Market value continues to surge as these vehicles are increasingly viewed as blue-chip investments that perfectly capture the raw, analogue theatre of the 1980s supercar era.
