This 1977 Porsche 911S coupe was acquired by its current owner in 2008 and was built as a Spec 911 race car for use in NASA and PCA Club Racing classes. Power comes from a carbureted 3.0-liter flat-six mated to a five-speed manual transaxle with a limited-slip differential, and the body is finished in green. The interior has been stripped and fitted with a roll cage, an OMP WRC-R racing seat, a Schroth harness, a WEVO shifter, a fire-suppression system, custom switchgear, an AiM camera, and a CoolShirt system. Other features include Braid 16? Fuchs-style wheels, four-wheel disc brakes, a 17-gallon fuel cell, MSD ignition, exhaust headers, and a stainless-steel exhaust. The engine and gearbox were most recently rebuilt in early 2019, and suspension components and braking system are said to have been refreshed in 2022. This 911 race car is now offered on dealer consignment in California with spare parts and a bill of sale.

The body has been fitted with JWE Motorsports front fenders, quarter panels, wheel liners, and quick-disconnect bumpers as well as a louvered taillight filler panel, and portions of the car were repainted in the current shade of green in 2020. The engine cover and front trunk lid are secured with pins, and an IROC-style rear spoiler with a wickerbill has been installed. LED lights have been integrated into the taillight assembly, and the windshield, quarter windows, and rear window are made from polycarbonate. Black graphics include racing numbers on the hood, deck lid, and doors along with Spec 911, 911 Cup, NASA, and other decals. Imperfections are noted in the finish.

Braid 16? Fuchs-style wheels are mounted with 225/50 front and 245/45 rear Hoosier R7 competition tires. The suspension has been modified and utilizes a Smart Racing Products front sway bar and shock inserts, Öhlins rear shocks, and 25/36 torsion bars. Work since 2020 included rebuilding the Carrera-specification rear calipers along with replacing the following components:

• Steering rack
• Trailing arm monoballs
• Front-right strut
• Toe and drop links
• Front calipers
• Front and rear rotors
• Front and rear wheel bearings

The interior has been stripped and refinished in gray, and a black roll cage was built by Rolf By Design in Sonoma, California. An OMP WRC-R racing seat has been installed along with a Schroth racing harness, and an aluminum floor panel has been installed on the passenger side. The plastic dashboard cover has been replaced and a custom-built aluminum lower dashboard panel was installed, and equipment includes a WEVO shifter, a cage-mounted AiM camera, a Garmin head-up display, a CoolShirt system, a brake bias adjuster, a fire-suppression system, a fire extinguisher, and custom switchgear.

The microsuede wrapping on the steering wheel is visibly worn, and instrumentation includes a rotated VDO 7k-rpm tachometer, a VDO combination gauge for oil pressure and oil temperature, an AEM air-fuel gauge, a Spec 911-logo block-off plate, and a large red warning light where the clock would be. A shift light has been added atop the dashboard. The car is not equipped with an odometer or speedometer, and total chassis mileage is unknown.

A black powder-coated 17-gallon ATL fuel cell is mounted in the front trunk, and the bladder and foam that was replaced in 2016.

The 3.0-liter flat-six was rebuilt in February 2019 by David Loop European in Monterey California. The dual triple-throat Weber carburetors and cylinder heads also were rebuilt at that time, and other equipment includes custom-made aluminum intake manifold spacers, an MSD AL6 ignition system, a throttle-by-cable system, a GT3-specification oil pump, a front oil cooler, a secondary oil cooler in the right wheel well, and 1.5? euro exhaust headers with a stainless-steel exhaust system.

The engine stamping is provided above and aligns with a 3.0-liter flat-six from a RoW 1982 911SC.

Power is delivered to the rear wheels through a 915 five-speed manual transaxle with a Guard Transmission limited-slip differential. The gearbox was rebuilt in February 2019, and it is fitted with custom-machined Turbo-specification stub axles, output shafts, and axle shafts.

Spare fenders, a front lip, a deck lid, rotors, ignition components, ducting, fuel cans, a funnel, brake pads, and a box of smaller parts shown in the gallery will accompany the car.
