Vehicle history
The vehicle is based on a 1978 Porsche 911 SC.
Between 2017 and 2021, the vehicle was comprehensively rebuilt without regard to cost or effort. The aim was to consistently exploit the technical potential of the individual components while retaining the classic character of the G-model.
The body was completely stripped, inspected and cathodic dip coated. All components were either extensively refurbished or replaced.
The paintwork was finished in Ardbeg Green, a specially developed colour inspired by the Scottish whisky brand Ardbeg.
Body
Numerous body panels were individually fabricated. These include, among others:
– handmade fender with ventilation slots
– Original Porsche RS components were fitted to the vehicle, namely –
– front apron
– rear apron
– front lid –.
Engine
The original 930 engine is fitted, enlarged to 3.6 litres of displacement.
The engine features classic twin ignition and carburettors. Technical highlights include, among others:
– The cylinder heads were inspected, measured and CNC-machined.
– The valve guides were replaced.
– The valves were blasted. The valve seats and stem ends were re-ground.
– The rocker arms were inspected, sorted and re-ground.
– The rocker arm shafts were lapped.
– The renewed camshaft was re-ground.
– The K-Jetronic injectors were inspected, sorted and cleaned.
– hand-rounded webs in the crankcase
– double-sealed crankshaft oil seal
– large oil pump
– 8-inch flywheel
– twin-disc clutch
– individually fabricated front oil cooler
Approximately 120 working hours alone were spent developing and manufacturing the front oil cooler.
Output is 382 hp at 402 Nm of torque.
With a kerb weight of just 1,044 kg, this results in an exceptional power-to-weight ratio. The engine was completely overhauled as part of the restoration and brought to a condition better than when delivered from the factory. Acceleration is comparable to that of a Porsche 997 GT3.
Transmission
The vehicle is equipped with a 915 gearbox that has been extensively overhauled, strengthened and optimised.
The gearbox features, among other things:
– mechanical reinforcements and optimisations
– external, electrically operated gearbox oil cooler
The technical configuration is based on the standard of a Porsche 935.
Suspension
The vehicle has the classic G-model torsion-bar suspension with KW Classic dampers.
Additional components:
– adjustable anti-roll bars
– bump-steer correction
– separately adjustable compression and rebound damping
The axle geometry and basic setup were developed by Manthey Racing on the suspension dynamometer. The vehicle was then further tuned and perfected during driving tests with AC Schnitzer suspension legend Manfred Wollgarten.
Wheels and brakes
It is fitted with handmade Fuchs wheels in 9J and 11J x 15.
The vehicle was originally driven with Michelin TB tyres; it is currently fitted with Pirelli P7 tyres.
The braking system comes from the Porsche 930 Turbo / 917.
The pedal assembly was modified around the accelerator and brake pedals to make heel-and-toe driving easier.
Some time ago, the key components were inspected and adjusted once again.
The vehicle received:
– wheel alignment
– major engine service
– comprehensive detailing of the interior and bodywork
– ceramic paint sealant
Documentation
The vehicle comes with:
– expert report
– extensive photographic documentation of the rebuild
– extensive invoice documentation totalling approx. € 450,000, –
– report for H registration
Additional accessories
In addition to the fitted ducktail, a ready-to-install whaletail is included with the vehicle.
A handmade bag set is also included with the vehicle.
The car impresses with its durability and has already been driven reliably for several thousand kilometres.
