You are buying a very original, custom ordered, light weight 1978 911SC. This car was ordered as a lightweight, it only has one (driver’s side) rear view mirror, no sunroof, no air conditioning, no fog-lights, manual sport seats, limited slip differential, Bilstein shocks/ suspension, limited slip differential, short 15” wider wheels and tires (7 & 8 x 15 instead of 6 & 7 x 16 with 205-50-15 & 225-50-15 tires instead of the regular taller wheels for faster acceleration.) Further, the car has a short shifter installed. This car drives like a go-cart!

The car just underwent a major refresh. It was all original, has never been in any accident, as you can see by its condition such as the interior it has lived a very gentle life. The front bumper, hood and the single driver’s side mirror had a lot of stone-chips. Further, somebody had put body side moldings along each side in the middle of the doors that looked ridiculous – it kept the doors dent-free. When we removed the non-original door moldings, some of the paint lifted with them, we decided to repaint some of the car. Further, the car had the not so nice factory all rubber whale-tail (it will come with the car), and we decided to treat this car with a reproduction early 930/911SC-Weissach deck-lid with a factory rubber lip. The roof of the car, as well as the rear bumper and valance are original paint. We decided to carefully sand down the rest of the car and refinish it in its original and ultra-rare mocha brown/mocha black color and the car looks stunning! The paint meter shows that the car is almost the same thickness as a new car, some areas slightly thicker. As you can see, the car has been updated with European H4 headlights and European tail-light lenses, all in excellent shape.

The car was running very well, but when we wanted to give it a tune-up and valve adjustment we found two broken lower Dilavar head-studs. As a result, we disassembled the engine (930/04 - early large port 3.0 US version), replaced all Dilavar head-studs with updated steel ones, put in new rings – this car features Mahle pistons and cylinders which are in outstanding condition, the guides in the cylinder heads were like brand new and had been replaced many years, but less than 10,000 miles ago, so we put in new Wrightwood Racing valve stem seals and left the guides alone. Further, the clutch has been updated with the all spring sport type without the problematic rubber center; pressure fed chain tensioners were installed, a pop-off valve was installed, plus all regular maintenance items such as new injector seals, intake runner bellows, new thermostat and breather seals, new spark plugs, original new spark plug wires, cap, rotor, new air/heater hoses etc. Of course the valves are freshly adjusted. The car features its original small 228mm (906 and 78/79 only 911SC) fan and fan housing – the original housing one had a crack (very common from previous, incorrect alternator service/replacement) and we sourced an excellent original replacement; the fan blades are perfect without any chips. We use silicon valve cover and sump gaskets. As the photos show the original exhaust is in excellent condition. We also checked the gas-tank, it is in excellent, original condition with no internal corrosion what-so-ever, as is commonly found these days as a result of the ethanol containing fuels.

The power robbing pollution air pump had been nicely removed, and it comes with the car complete with the air injectors, manifold, bracket and pulley if you ever want to make the car 100% original.

All windows are nice, clear and free of scratches or chips, the headliner is in stunning condition without any tears or discoloration, even the dash and sun-visors are excellent, so is the plaid/cork interior, and cork interiors with plaid dress inserts per certificate of authenticity are ultra-rare and are very, very 70s and gorgeous! This car even features its original radio (with the operation manual in the glove-box), and amazingly features the original door speakers with the ultra-hard to find original door speaker covers in outstanding condition. It is almost impossible to find a 38 year old car this original and well maintained. Even the tool-kit and original emergency air compressor are still there as shown; even the original bag that used to contain a pair of gloves for a tire change and or course the owner and maintenance manual are there complete in their original pouch.

We even found a fresh set of tires for the car, almost impossible to find in this original 205-50-VR15 & 225-50VR15 size and configuration, especially the rear tires. Also, the brakes are freshly serviced with new front rotors and pads.

To keep the engine running cool, the car is equipped with a Terbatrol front oil cooler system (in the right front fender), these were extremely efficient with much better heat dissipation than the original loop coolers or the multi-tube coolers had. Also, a nice, small hole was cut into the front valance panel to channel more cooling air into the oil-cooler, a desirable update. Even the original, factory, super loud red fanfare trumpet horns are still functioning and in the car.

This car is an excellent investment opportunity and can be enjoyed, it is an excellent driver. Thoroughbred Motorsports is a vintage Porsche parts specialty house and restoration shop and not a car dealership. The car has a free and clear PA title in Thoroughbred Motorsports owner’s name, and it was sold to him many years ago as a 1 owner car, but we have no documentation to prove it's single owner history.

Good luck bidding!

The car has been corner-weighted. It's total weight as it sits with all fluids and the gas tank about 1/3rd filled is 2,566 lbs. The car is well balanced with corner weights of:

left front: 504 lbs

right front: 496 lbs

left rear: 785 lbs

right rear: 781 lbs.

The car has a brand new battery.

We installed a new engine sound pad before the engine went back in.

The pedal cluster is freshly refurbished with all bronze bushings.

Tires are new Kumho 205-50VR15 in the front and almost brand new, very recent Falken 225-50VR15 in the rear. These tires feature a very similar thread pattern and rubber mixture and work very well together. Mostmanufacturershave stopped manufacturing these sizes and they are very hard to find.
