Singer's tribute to the 1970s 930 Turbo — a 964-based, twin-turbocharged 'reimagined' Porsche.
Revealed in 2022, the Turbo Study is Singer's separate, narrowed-shoulder commission that pays explicit visual tribute to the 1970s 930 Turbo while using the company's now-mature 964-based engineering. The 3.8-litre twin-turbocharged flat-six is air-cooled with water-cooled cylinder heads and produces approximately 450 bhp, with a 6-speed manual transmission and optional all-wheel drive.
Like all Singer programmes, the Turbo Study begins with a customer-supplied 964 and is built to a personalised specification at Singer's California facility.
Singer's first turbocharged commission and a clear collector's signal that the company is broadening beyond the naturally-aspirated Classic Study.

Start with identity, paperwork and originality. For the Singer Turbo Study, the strongest cars have continuous ownership history, matching numbers where applicable, original books and tools, factory build documentation and evidence of work by manufacturer-approved specialists. Original commission paperwork, Singer service history.
Twin-turbo engine is bespoke; intercooler, charge-air plumbing and bespoke ECU should be checked at every service. A proper pre-purchase inspection includes cold-start behaviour, ECU diagnostics and fault-code history (where applicable), leak-down or compression testing, underbody photography, suspension and chassis inspection, brake condition and a long enough road test to expose heat-related faults. Deferred maintenance on a car of this class is almost always more expensive than buying a better-sorted example.
Use a paint-depth gauge, lift access and a specialist familiar with the model's factory panel gaps and finish standards. Collector value is dramatically affected by structural repairs, refinished panels, poor paintwork and missing factory trim or option content. Documented cosmetic refresh is acceptable; concealed accident or fire damage must be priced severely.
Original commissions with Singer paperwork; unmodified delivery spec; AWD vs RWD market preference is regional. Specification, colour, options and limited-build variants move values significantly. Buy the best-documented example in the most desirable specification you can justify, rather than a tired example of a rarer derivative that will need years of corrective work.
Regional ranges authored independently — each reflects its local market, not an FX conversion
Budget annually even if the car is used sparingly. Fluids age, tyres and date-coded rubber components must be replaced regardless of mileage, and stored cars need exercise. A documented maintenance rhythm protects both reliability and resale value.
Service realistically through Singer or named partners only. Before purchase, confirm parts availability for model-specific bodywork, electronics, gearbox and engine components. A discounted car waiting on unobtainable parts or a factory service slot is rarely a saving in collector ownership.

Strong demand carryover from the Classic Study; the Turbo Study is the marque's growth narrative.
