Description: 1981 Porsche 924 GTR IMSA VIN: 4159560 WR001-84 * One of 17 Porsche 924 Carrera GTRs * Comes with FIA papers and Historic Technical Passport * Comes with spares, including spare engine Porsche built 17 examples of the 924 Carrera GTR. Top speed was rated at 180mph, 0-60 was sub-5 seconds and the price in 1981 was $75,000. They came from Porsche with fully integrated roll cages, fully adjustable suspension, and four-piston 935 brake calipers squeezing 12.2 discs. The engine is a highly modified version of the 2.0 L I4 used in all 924s, featuring dry sump lubrication. The 4-speed transmission has a dedicated cooling system, and the rear differential is 80-percent locking. Weighing just over 2300 lbs, the GTR was good for 375 hp and 299 lb-ft of torque thanks to a boost pressure of 21ps on a static compression ratio of 7.1:1. One of the GTR's most notable victories was a class win at the 24 Hours of Le Mans in 1982, where the light and nimble car won on street tires. 5 street tires to be exact. Not 5 sets of tires, 5 tires total. This example of the GTR was delivered to Tom Winters from Porsche in 1981, and was driven by himself and Bob Bergstrom, starting with an appearance at Lime Rock in 1981. Running under the banner of Whitehall Capital - Promotions they would race the car in the IMSA GTO and GTU classes over the next several years, including multiple appearances at Sebring and Daytona. Being an active racecar, there were always modifications as the car passed through the seasons. In 1982 the car was modified to increase cooling to the engine, and the engine compartment sidewalls were removed. The turbo was also moved from the right to the left side of the engine compartment. In 1984 the IMSA rules were changed allowing a space frame, so to keep car as competitive as possible the GTR was rebuilt around a new space frame. All the original GTR mechanical components and body were hung on the new frame. This frame, WR001-84, is still in the car. In 1986 the car was sold to Dave Pannacione who campaigned it at Daytona and Sebring. For 1987 the 924 moved to the ownership of Don Chilsen and was raced by him and Peter Dawe and Alex Tradd under the sponsorship of Creative Coachwork until 1988. In 1989 the car was retired from racing and went into the private collection of Steve Wellings until 2011. A new owner purchased the car in 2011 and brought the car to Germany. Beginning in November 2011 and completed in April of 2012, the car received a complete mechanical and cosmetic restoration by Reiner Telkamp of Ludwigsburg, Germany. During the restoration the engine, transmission and differential were completely rebuilt. All critical parts were x-rayed. The exterior was dressed in its original 1984 livery. To address the Achilles Heel of the turbo 924, the engine cooling was modified so that both the engine block and the cylinder heads have their own dedicated cooling systems. Since its restoration the 924 has successfully participated at historic races at Hockenheim, the Nurburgring and most recently at 2013 Rolex Monterey Motorsport Reunion.
