There are many classic 911s that look as if they promise something.
This 911 delivers on that promise.
Based on an original 1973 chassis, this Porsche has been purposefully built over the years into a raw, mechanically compelling interpretation of the legendary 911 Carrera RSR 2.8.
The result is a meticulously assembled RSR-inspired 911 in which driving experience, mechanical purity, and visual authenticity take center stage.
Technology & Character
The heart of the car is a 3.0 SC aluminum engine block, professionally built to 2.8 RSR specifications with 92 mm RSR cylinders, RSR pistons, and mechanical fuel injection (MFI).
The rebuilt 915 transmission with short shifter reinforces the car’s pure, mechanical character, making every shift feel direct and unfiltered.
The car was recently retested on the dynamometer, where the engine delivered 237.5 hp at 6,633 rpm.
Combined with the low weight, the direct throttle response of the mechanical injection, and the short 915 transmission, this creates a driving experience much closer to a 1970s race car than to a classic street-going 911.
Driving Experience
Everything about this car feels light, mechanical, and direct.
The steering, the clutch, the throttle response, and the way the car reacts to weight immediately make it clear that comfort was never the starting point.
The harder you drive it, the more the car comes into its own.
Appearance
At Dieben Collectables, a conscious decision was made to go for a more understated and timeless presentation. The previous livery was removed, and the exterior was given subtle Carrera stripes that visually bring the car back to the spirit of the RSRs.
It is precisely in its proportions that the car really stands out. The low stance and wide rear give the car exactly the taut appearance for which the original RSRs became so famous.
The deep original Fuchs wheels in 9J and 11J, combined with the new Pirelli Cinturato P7 Vintage tires, reinforce the car’s period-correct character.
The interior follows the same philosophy as the rest of the car: lightweight, functional, and entirely focused on driving. The Prototipo-style steering wheel, classic bucket seats, exposed roll bar, and minimalist finish give the car the exact atmosphere of a 1970s endurance 911 where everything revolves around driving.
Details such as the central fuel filler, Cibié spotlights, and minimalist finish reinforce the car’s functional character without feeling forced.
History & Documentation
This exact car was previously featured in RTL GP Magazine and appeared at Circuit Zandvoort during a track session with Jan Lammers.
Since approximately 2007, the car has been verifiably documented with invoices, maintenance history, and photographic evidence. Since 2019, maintenance has been performed by Porsche Specialist Visser in Hilversum
Condition
As with virtually every air-cooled 911 that has seen some use, there are a few areas of concern. The car has some cosmetic imperfections and an oil leak at the crankshaft seal.
On the other hand, the car is mechanically sound and has demonstrably been built up and maintained with care.
Asking Price
The asking price deliberately reflects the type of car this is.
This is not an over-restored museum car that fears mileage or stone chips. It is an air-cooled 911 built to be driven, and that is exactly where cars like this come into their own.
