In 1978, Porsche introduced the latest version of their 911 designated the '911SC'. It featured a 3.0-litre six-cylinder engine with Bosch K-Jetronic fuel injection and a 5-speed (915) transmission. Originally, power output was 180bhp, later 188bhp and subsequently, by 1981, an impressive 204bhp.

This particular left-hand drive 1979 911 3.0 SC was originally supplied new to Colorado and raced in the Porsche Club of America Enduro Championship. The car's history file contains its old Colorado Certificate of Title and details of much expenditure from its time in the USA. 

Our vendor purchased the Porsche and imported it into the UK in August 2015 with all import duties and taxes fully paid, generating a NOVA reference number. The car was then prepared and raced by our vendor and his friend in their inaugural season of UK motorsport in 2016. 

For the 2017 season the engine was fully rebuilt by marque specialists, Pro 9 Porsche and upgrades included; Jenvey throttle bodies, high compression JE pistons, a coil pack conversion, Omex ECU and new loom, new injectors, RS cams, an RSR flywheel, and competition clutch. The invoice for this engine work was just under £15,000 for this work however peak power was now a very competitive 264bhp. The car is fitted with a Giken LSD and the gearbox was rebuilt at the end of 2017 with a Seine gate shifter ( it has only completed one race since the rebuild). Wevo mounts hold both the engine and gearbox firmly in place. 

Bilstein shock absorbers are fitted along with Tarett adjustable roll bars, Elephant Racing adjustable spring plates, a tower strut-brace, Monoball bushes, and tie rods from a 911 Turbo. Retardation benefits from competition 6-point callipers at the front and 4-pots at the rear, along with a rebuilt master cylinder and pedal box. 16” wheels are fitted and shod in Toyo R888 tyres.  The geometry was professionally set up by specialists Centre Gravity and there are details included in the file. 

The interior features an Autopower bolt-in roll cage, a Recaro bucket seat, in-date Sparco harness and a removable Momo steering wheel. The fire extinguisher will have its annual service prior to the auction and, as always, we recommend that all prospective buyers satisfy themselves as to the currency and legality of all safety equipment in the car. An ongoing weight reduction programme has resulted in the dry weight finally reaching 1040kg. This smart 911 has just been fully repainted in Silver and no longer sports the Martini decals.

Having enjoyed the car for two seasons, our vendor is moving onto another motorsport project, and hence this car has come to the market. A great entry-level Porsche racer that could be used in CSCC's 'Advantage Motorsports  Future Classics' Series, the 750MC Roadsports Championships, or would make a great Sprint or Hill Climb car.
