The 'RSR', introduced in 1973 by the factory as an evolution of the already potent 2.7 RS, was both an official 'works' team car built to contest International World Championship 'Group' 4 GT endurance events and also available for privateer race teams in full competition trim. The 'RS' itself was a hugely successful development of the standard 2.4-litre flat-six. The engine was bored out to 2.7 and carefully massaged to produce 210 horsepower which was fed through a five-speed gearbox with uprated 4th and 5th cogs, all contributing to remarkable acceleration and a top speed of over 150 mph. Revised and stiffened suspension and larger four-wheel disc brakes complemented the increased power and ensured the RS remained perfectly balanced.

An initial order of 500 RS' was produced to meet FIA 'Homologation Requirements' but the cars were so popular that production eventually totalled some 1,580 units. The most hardcore, no-nonsense, version of these race-focused 911s was the RSR. These Rennsport specials, with their dramatic, pumped-out wheel arches, intensified the standard 2.7 RS flavour in every way. Wider, lighter, faster, and more capable in every performance category, the RSR was the RS unrestricted, dialled in for maximum capability with scant regard for creature comforts. The formula was successful – the 2.8 RSR is still recognised today as one of Porsche’s most successful race cars. Sadly, however, if the RSR was in the 'Periodic Table of Elements, it would be 'Unobtanium' as just 49 were built resulting in them rarely coming to market, and when they do, the numbers are not for the faint-hearted, broadly equivalent to a row of terrace houses in Bradford. Consequently, anyone wishing to experience the addictive blend of handling, balance, performance, feel and simple purity that is the RSR, has no choice but to create their own.

We are pleased to offer for sale an original 1973 left-hand drive, 911T brilliantly modified to 2.8 RSR specification and accompanied by an FIA Technical Passport (Competition GT; Class GTS27). Unusually, for a conversion of this nature, the car is UK-registered with Historic Vehicle tax status and could be used on the road or circuit.

Chassis Number 9113100481 was originally delivered to the USA in March 1973, however much of its early history is unknown. In 1991, it was registered as belonging to Patricia J Vanleen of Baton Rouge, Los Angeles and in October 2009 was returned to Germany in the care of the S & N Automobilzentrum Aachen Gmbh. From July 2010 until October 2017, the car was the pride and joy of the previous owner, who sold it through Silverstone Auctions Porsche sale in October 2017. During his seven-year ownership, upon arrival in Germany, the decision was taken to create an accurate RSR replica using the 911T as a basis and this work was entrusted to 'Scuderia-Eleven' with the engine left in the capable hands of Bienert Boxer-Motoren, who have over 25 year's experience in preparing air-cooled Porche engines.

The specification is too long to detail here but briefly; Original engine type 911/51 (2.4 Litre, 140bhp) replaced with 1974/75, 911/41 engine taken out to 2.8-litres, compression ratio 10.8: 1 producing 265 bhp with mechanical fuel injection, and dual ignition. Five-speed, 'short-shift' 915 gearbox and a ZF LSD. Front strut-brace, adjustable front shocks, adjustable front and rear anti-roll bars, front and rear polyurethane axle bushes, thicker torsion bars, and steel braided brake lines. Front tyres: 215/55 R1, rear tyres 270/45 R15. Wheels front: 9Jx15 and rear 11Jx15. The bumpers, front and rear bonnets and the wings were replaced with composite parts. 'Makrolon' polycarbonate side and rear windows. Welded-in multi point roll cage. Sports steering wheel, sports seats with full harnesses and aluminium footplates. The final set-up was completed by Kadach.com for Harry Utesche at DLS Automobile in Stuttgart.

The previous owner, a well-known racing driver who has raced RSRs in the past, admits “There
