📖Generation guide
930 Turbo (3.0L) • 1976-1979
The early 930 Turbo featured a 3.0L turbo flat-six engine producing 234hp, paired with a 4-speed manual transmission. Known for its exhilarating power delivery, the 'widow-maker' reputation is a notable aspect of this generation.
930 Turbo (3.3L) • 1986-1989
This later model introduced a 3.3L turbo flat-six engine with power output between 282-296hp and a refined 5-speed manual transmission (G50). The 1989 model year marks the last of the air-cooled 911s, greatly enhancing its collector appeal.
930 Turbo (Slantnose) • 1986-1989
Factory Slantnose or Flachbau models offer unique styling and command significant premiums due to their rarity. Prices for these variants can reach astonishing heights, especially in pristine condition.
930 Turbo Cabriolet • 1987-1989
Convertible enthusiasts can opt for the Cabriolet variant, which offers a blend of open-air experience and turbocharged performance, attracting its own dedicated collector base.
930 Turbo Targa • 1987-1989
The Targa variant combines the hardtop structure with a removable roof panel, appealing to those seeking style and functionality in a classic Porsche.
Known issues by generation
The 930 Turbo, particularly during the 1976-1979 production run, exhibits unique engineering challenges, most notably the KKK turbocharger lag and the notorious 'widow-maker' boost spike, which can lead to lift-off oversteer. The later models (1986-1989) improved upon these aspects with enhanced power delivery thanks to an air-to-air intercooler. However, they still face issues like KKK turbocharger rebuild needs every 80-120k miles and potential head-stud pull due to high cylinder pressures. Regular valve adjustments every 15-20k miles are crucial, as is meticulous attention to the gearbox, especially the notorious Type-915 4-speed, which can suffer from synchro wear and shifting difficulties. The Getrag G50/50 found in the 1989 model provides a more reliable option.
Donation value by condition + generation
The 930 Turbo represents one of the pinnacle tiers in the air-cooled Porsche collector market. The manual transmission variants, particularly the 1989 G50/50, command impressive values, often exceeding $300k at auctions. Meanwhile, earlier 4-speed models range from $80k to $150k depending on condition and provenance. Collectors place a massive premium on original paint, and any color change alerts buyers to potential issues. Verification through a Porsche Certificate of Authenticity (COA) is essential, as is confirmation of matching numbers. Auctions like RM Sotheby's and Gooding & Company provide essential comparisons and validation for potential donors.
