Spotted in Europe is a 1971 Porsche 911 ST for $1,850,000 USD on Ebay. This S/T is an all original , numbers matching car. There were only 15 produced in 1971. The seller states this car comes with documented race history as well as Porsche COA documents. Not much more is said about the car in the ad. Not even the picture is representative of the actual car. The real car is green with black interior. This is a super rare car and will need to be researched thoroughly before buying.
The racing version of the upgraded 911 S became known as the 911 ST. Taking the lessons learned from the development of the 1967 911 R, the engine car went on a diet. Once again, thinner gauge steel was used for the body tub and there was an extensive use of fiberglass for the external body panels and Plexiglas for all windows but the windshield. Removed were any kind of ‘bright work’ and body fillers normally used in street car production. Added were wider forged aluminum Fuchs wheels and the front brake calipers from the 908/2.
The 911ST was originally intended to primarily be a rally car, and it enjoyed much success in the hands of Swedes Bjorn Waldegaard and his co-driver, Lars Helmer. The 911 ST also found some success on the race track in the hands of privateers, however. 911 STs were entered at Le Mans and most of the other important European races. Its greatest success came while in the hands of Peter Gregg and his Brumos team.
The Porsche 911 2.3 and 2.4 ST/GT cars were produced in 1970 and 1971. These were intended as racing cars and served as a replacement for the T/R that had been in limited production since 1968. The ST/GT ran in Group 4 competition and the FIA allowed Porsche to increase the bore and ultimate enlarge the engine. Displacement increased to 2247cc due to the 85mm bore and unchanged stroke of 66mm. Porsche dubbed these vehicles as the 911/20.
Porsche took the opportunity to enhance all areas of the engine. Biral cylinders, higher compression ratios, Mahle pistons, twin-plug heads, polished connecting rods and plastic intake trumpets were a few of the improvements. Horsepower jumped to an astonishing 240. The body material was exchanged for lightweight material and all non-essential interior items were removed. Alloy doors, hoods, bumpers and wheel arches were comprised of an exotic and ultra-thin fibre-glass material. When work was completed, the vehicles weighed just 850 kg.
