Isringhausen Imports presents a unique occasion for car enthusiasts and collectors: the 1991 Porsche 911 “Greenwich Commission,” reimagined by Singer Vehicle Design.
With 1,747 miles, this Type 964 model shows its heritage and transformation. An Oxblood Red leather interior complements its classic GT Silver exterior. Under its exterior is an engine built for performance. The 400-horsepower hand-built 4.0L F6 engine retains the 964 case with custom crankshaft, 50mm ITBs, a heavily reworked 997 GT3 Plenum, and extreme high-flow heads all run by a MoTeC M1 series ECU. Shifting is done by a G50 6-speed manual gearbox which is the cherry on top of when old meets new in what most enthusiasts consider one of the best driving cars ever built.
The original rack-and-pinion steering has been upgraded using the Type-993 model series technology, ensuring better handling and driving experience. This shows attention to performance and tradition in the restoration.
Aesthetically, optional exterior features include a center-fill hood, carbon fiber roof, 17-inch Forged Aluminum Fuchs-style wheels, Brembo Carbon Ceramic Brakes finished in a beautifully contrasting Champagne Gold, and fender-mounted oil filler. These are not just functional but also symbolic of the car’s past and racing DNA. Inside, the interior appointments include a Ivory Headliner, Red Wine Velour carpeting, extended black leather Coverings, Piano Black seatbacks, leather-wrapped Momo Protipo steering wheel, Porsche Classic Nav-Stereo with subwoofer and XM Radio.
The list of mechanical and cosmetic improvements integrated into this vehicle is extensive. Each aspect was carefully considered, creating a classic air-cooled 911 that represents style, performance, and craftsmanship—a collector’s item that also shows the potential of automotive reimagination. Additionally, this offering provides a chance to own a unique vehicle without the usual waiting periods associated with Singer Vehicle Design.
