The first import window introduced the 3.0L turbo flat-six engine, producing 234hp with a 4-speed manual transmission. Known for its turbo lag and explosive power, this generation earned its 'widow-maker' title.
930 Turbo (1986-1989) • 1986-1989
The second import window featured a 3.3L turbo flat-six, offering improved power delivery and a Getrag G50/50 5-speed manual transmission. The 1989 model, being the final year, commands a significant collector premium.
930 Turbo Slantnose (1986-1989) • 1986-1989
Factory-option Slantnose variants feature a flat-nose headlight conversion, attracting a premium of $50-150k over the standard 930 Turbo. Authenticity is critical in distinguishing factory vs. aftermarket conversions.
930 Cabriolet / Targa (1987-1989) • 1987-1989
These body-style variants provide unique open-top experiences while maintaining collector interest in the 930 lineage, featuring the same engine options as the coupe.
Known issues by generation
The 930 Turbo has specific issues that collectors should be aware of. Early models (1976-1979) face challenges with the KKK turbocharger, known for its lag and sudden power surge, leading to lift-off oversteer. The 1986-1989 models benefit from improved turbo technology and air-to-air intercooling but require diligence in maintenance, particularly with KKK turbocharger rebuilds every 80-120k miles. Head stud pull and valve adjustments also demand attention to prevent costly repairs. Regular servicing and preventive maintenance are crucial to keeping these legendary vehicles in optimal condition.
Donation value by condition + generation
The value of the Porsche 930 Turbo varies significantly based on condition, provenance, and documentation. Manual-transmission variants, especially those equipped with the G50/50 gearbox from 1989, command a collector premium that is iron-clad. Original paint and matching numbers are essential for maintaining high value; any factory color change could result in catastrophic depreciation. The Porsche Certificate of Authenticity (COA) is mandatory for serious collectors, and matching-numbers verification can escalate valuations significantly. Auction comparisons, including Hagerty, BaT, and RM Sotheby’s, provide essential data for assessing value.
Donation process for this model
Donating a Porsche 930 Turbo involves a thoughtful process to ensure the vehicle's value is fully recognized. A qualified appraiser is mandatory to facilitate the donation, particularly for those exceeding the IRS Form 8283 Section B threshold of $5k. Clean, low-mile examples typically require enclosed transport for safe delivery. Documentation such as original paint, matching numbers, service history receipts, and Porsche COA verification is essential. A pre-purchase inspection (PPI) at a Porsche specialist is standard practice to ensure the vehicle's integrity before donation.
