📖Generation guide
930 Turbo (3.0L) • 1976-1979
Known for its thrilling performance, the early 3.0L turbo flat-six produces 234hp and is distinguished by its 4-speed Type-915 manual. This version is infamous for its 'widow-maker' reputation due to turbo lag and sudden power delivery.
930 Turbo (3.3L) • 1986-1989
This iteration features a more refined 3.3L turbo flat-six engine generating up to 296hp. The 1989 model, equipped with the Getrag G50/50 5-speed, is the last of the air-cooled Porsches and is highly sought after.
Slantnose / Flachbau • 1986-1989
The factory Slantnose variant features a unique flat-nose headlight conversion, commanding a premium that ranges significantly depending on originality and provenance.
Cabriolet and Targa • 1987-1989
Offering a different driving experience, these variants hold their own collector tiers and are appreciated for their distinct styles while still featuring the legendary turbocharged performance.
Known issues by generation
Each generation of the Porsche 930 Turbo has its unique set of challenges. The 1976-1979 models are known for KKK turbocharger issues resulting in boost spikes and lift-off oversteer, while the 1986-1989 models benefit from improved power delivery but still require careful attention to KKK turbocharger maintenance and the critical head-stud replacement to prevent failures. Regular valve adjustments every 15-20k miles and the necessity of ensuring proper gearbox health, especially in the pre-1989 4-speed models, cannot be overlooked. Collectors must be vigilant and proactive in addressing these known issues to maintain their vehicle’s value and driving experience.
Donation value by condition + generation
The Porsche 930 Turbo has reached peak collector-tier value, with late-model G50/50 examples often fetching between $150k and $300k at auction, while earlier variants still command strong prices of $80k to $150k. The manual transmission, especially the G50 variants, is a significant factor in these values, as collectors prefer the direct driving experience over Tiptronic alternatives. Original paint and matching numbers are paramount, with a factory color change being viewed as a catastrophic red flag for collectors. Documentation, including a verified Porsche Certificate of Authenticity (COA), is essential for establishing provenance and ensuring that vehicles meet the rigorous standards expected in this collector tier.
Donation process for this model
Donating your Porsche 930 Turbo involves a few essential steps to ensure compliance with IRS regulations.
