Description
1982 Porsche 911 SC 3. 0 Targa Flachbau
Guards Red | Black Interior | 3. 0-Litre Flat-Six | Jenvey ITB Induction | Manual | LHD | 62, 048 Miles
An exceptionally individual example of the air-cooled Porsche 911, this 1982 911 SC 3. 0 Targa Flachbau is presented in the quintessential Porsche colour combination of Guards Red over black.
Combining the distinctive, low-profile Flachbau silhouette with the character and mechanical purity of Porsche's naturally aspirated 3. 0-litre flat-six, this particular example has benefited from an extensive programme of restoration, mechanical rebuilding and sympathetic development.
With £92, 827. 09 of documented expenditure since 2020, the car represents a substantial investment in both its mechanical integrity and overall presentation. The result is a thoroughly developed classic 911, retaining the analogue driving experience for which the marque is celebrated, while incorporating a number of carefully selected modern enhancements.
The car has covered 62, 048 miles, with very limited use throughout much of its later life. A substantial history file accompanies the vehicle, documenting specialist maintenance, restoration and development work carried out in both the United States and United Kingdom.
Engine & Performance
At the heart of this 911 is its naturally aspirated 3. 0-litre air-cooled flat-six, which has undergone a comprehensive mechanical rebuild by Porsche specialists Rennspeed.
The engine was fully dismantled and rebuilt, with extensive internal component renewal, including replacement pistons and cylinders, crankshaft, bearings, timing components and associated ancillaries. The cylinder heads were machined and fitted with new valves and guides, while a new clutch assembly and engine mounts were also installed.
Further development has seen the installation of a Jenvey individual throttle-body (ITB) induction system, complemented by standalone programmable engine management.
This sophisticated induction arrangement provides individual-runner throttle control, offering enhanced throttle response and a more immediate connection between driver and engine, while preserving the unmistakable character of a naturally aspirated Porsche flat-six.
The conversion incorporates dedicated engine-management wiring, bespoke ECU integration, crank-trigger and sensor systems, together with subsequent rolling-road development and calibration.
More than £30, 000 has been invested in the engine and induction system alone, including £12, 900 for the Jenvey ITB and standalone ECU installation.
The exhaust system has also been developed as part of the wider engine programme, completing a carefully considered mechanical package.
Transmission & Drivetrain
The manual gearbox has undergone a comprehensive rebuild, including the renewal of first- and second-gear dog teeth, selector components, synchroniser rings, internal seals and associated components.
Further attention has been given to the gear-selection mechanism, with refurbished linkage components, a short-throw shift arrangement and subsequent adjustment and refinement.
The clutch system has also been renewed, including a replacement clutch assembly and cable.
Together, these works represent a significant investment in the drivetrain, complementing the extensive engine development.
Chassis, Suspension & Braking
The restoration programme has extended well beyond the engine and transmission, with considerable attention devoted to the car's chassis and running gear.
Both front and rear suspension assemblies have been extensively dismantled, inspected and refurbished, with the renewal of bushes, mounting components and associated hardware where required.
The steering system has received similarly thorough attention, including work to the steering rack, coupler, column components and associated linkages.
The braking system has been comprehensively recommissioned, with professionally rebuilt front and rear calipers and a replacement brake master cylinder.
The car sits on traditional Fuchs alloy wheels, complemented by 28 mm wheel spacers, with final suspension geometry and alignment undertaken following the mechanical works.
Bodywork & Restoration
Presented in Guards Red, the car retains the dramatic and unmistakable appearance of the Flachbau, a distinctive interpretation of the classic 911 silhouette.
The restoration programme has included extensive attention to the engine bay and front luggage compartment, both of which have been stripped, inspected and refinished.
Corrosion repairs and preventative measures have been undertaken where necessary, alongside the refurbishment or replacement of numerous brackets, mounting components, seals and ancillary fittings.
The engine bay has been carefully refinished, with attention also given to engine tinware, brackets and surrounding components.
The front luggage compartment has similarly benefited from repairs, refinishing, renewed protective coatings and electrical refurbishment.
Further exterior work has included the renewal of various seals and trim components, followed by professional machine polishing and detailing.
Interior & Equipment
The black interior provides a purposeful contrast to the Guards Red exterior, retaining the familiar and engaging environment of the classic air-cooled 911.
A significant programme of interior refurbishment was undertaken in 2003, including renewed front seat upholstery and extensive work to the Targa roof and associated trim.
Fewer than 1, 000 miles have been covered since this interior refurbishment, contributing to the car's overall presentation.
More recent works have included the refurbishment of the pedal box, replacement of pedal bushes, adjustment of the heater controls and further attention to interior fittings and mechanical components.
The car has also benefited from the installation of a modern audio system.
Air Conditioning & Electrical Systems
An important element of the recent development programme has been the installation of a modern electronic air-conditioning system.
This substantial conversion incorporates a new compressor, condensers, receiver-dryer, associated plumbing, bespoke mounting arrangements and dedicated electrical controls.
The electrical system has also received extensive attention, with both front and rear wiring looms inspected and refurbished, damaged or redundant wiring removed, and new engine-management and fuel-pump wiring installed.
Additional works include the installation of a rear fuse and control board, refurbishment of lighting and mirror wiring, replacement headlamp connectors and the fitment of LHD Wipac headlights.
These improvements represent a considerable investment in the car's electrical reliability and usability.
