Description

Where would we be without the Porsche 911? The do-it-all sportscar that can trace its history back through the last 6 decades has continually been the benchmark to stack all newcomers against.

If one was to ponder however, what would happen if you took all the great bits from various iterations to create what some would see as the ultimate air-cooled 911? Someone did just this, and created the stunning example you see before you.



Purchased as a standard 1985 narrow-body Carrera 3. 2 in Prussian Blue by the previous owner, the 911 was used and enjoyed, and, over the years as parts wore out, were either replaced or more often upgraded until the whole car has been refreshed and upgraded to the specification and condition presented today.



During 2015 and 2016 the 911 underwent general body maintenance including replacement of the sills, kidney bowls, B-posts and genuine Porsche panels where needed, and converted to ‘Wide-Body’ utilising 911 Turbo steel rear arches and matching steel front wings. This was just the start however, as the custom fabrication work included deleting the roof rain gutters as per RUF cars in that period, converting to a single windscreen wiper and deleting both the fresh air intake and windscreen washer jet; the latter now moved to the wiper arm.

At the front end the fibreglass bumper was extensively remodelled in the style of the now-famous Porsche IROC cars. Limited to only 15 examples, the 911 RSR was created to compete in the highly regarded international racing series in the 1970’s. That bumper – now housing the huge RSR-style oil cooler - channels hot air through and over the custom bonnet, not only keeping oil temps at bay but also aiding aerodynamics. It's the same at the rear, this time in 1974 3. 0 RS/ IROC-style with discreet ventilation holes, and grilles mounted behind the offset rear number plate to further aid cooling. And of course, no period 911 would be complete without the iconic ‘Whale Tail’ spoiler, this example sporting an IROC/ RSR inspired example mounted on a lightweight engine cover. Even the wing mirrors were chosen for their aerodynamic benefits.

Upon completing the extensive upgrades and ensuring the car was made rust free, the owner chose not to repaint the car in its original shade of Prussian blue (Preußischblau), instead going with a period Porsche shade of Arrow blue (305/ pfeilblau).

For reliability and usability, a Dansk fuel tank was also fitted, along with a lightweight alloy protective belly pan. The car now also features lightweight 964-style front and rear screens which feature heating elements if the next owner wishes to wire them in, and 993 rear quarter glass and seals.

While the works to the exterior were both intensive and stunning, the running gear featured no less attention. The original 3. 2 flat-6 was removed and, in its place, now sits a 3. 6 litre example from a ‘964’ 911. However, before it was slotted into its new home it was given to renowned engine builder Nick Fulljames of RedTek for a complete overhaul with no stone left unturned, and now features many upgraded components – too many to list here – so please take the time to read through the specification list.

The engine has only covered 18, 000 miles since and having been tuned by known expert Wayne Scholfield of ChipWizards, the engine produced an extremely healthy 318 BHP and 293 lb ft of torque.

The noise is intoxicating, that flat-6 howling through a custom titanium exhaust system exiting through a 997 911 GT2 RS rear silencer. The gearbox was handed to highly respected Porsche specialists RSR Engineering, who overhauled the late 915 unit using genuine Porsche parts. For the suspension Chris Franklin at Centre Gravity was called in to thoroughly work his magic and the car now features a fully adjustable suspension setup.

Moving to the inside a focused but minimalist style was employed. No harsh race seats or roll cages, instead reclining Recaro seats fit perfectly with the alcantara headlining and A pillars.

The carpet is an accurate recreation of the 911 turbo carpet of the period, and of special note are the interior door pulls which were originally activator pull cords for fighter jet ejector seats, noting the passenger side which had actually been used to eject.

This stunning example is idea for road or track use, uses only the best components from the best names in the business and to replicate its condition and specification would cost significantly more that its purchase price. Please contact for further information and to book a viewing. Exterior:
