1982 Porsche 911SC

History

The Porsche was acquired by the prior owner in 2006. Since that time the car has been extensively developed and run in Porsche Owner’s Club (“POC”) events. The current owner purchased the race car in 2021. He drove the car at several club outings before the engine failed during a 2024 POC event at Sonoma Raceway. The engine was then shipped to the original engine builder, JB Racing, in Florida. JB Racing was subsequently sold, and the disassembled engine was returned to the owner. Since then a replacement engine case has been purchased but the rest has not been repaired and reassembled. That is the current status of the car.

Description

The Porsche is based on a 1982 911SC tub. The tub was fitted with a carbon fiber hood, spoiler, doors, and a carbon fiber front splitter. The front 996-style air dam, rear wing, and fender flares are fiberglass, and the rear and side windows are made of Lexan. Up front are a Fuel Safe 100-liter fuel cell, and a three-gallon Peterson dry sump oil tank.

We understand that the car’s damaged air-cooled 3.7-liter flat-six engine was built with the parts listed below. What parts are salvageable needs to be determined. However, the engine builder offered the owner $18,000 for the parts as-is. Having said that, the  owner would prefer to sell the car and its engine as a complete package, as-is. 

Engine:

• 13:1 compression pistons
• Twin-plug cylinder heads with stainless steel 52mm intake and 41mm exhaust valves
• Stroked crankshaft
• Carrillo rods
• Custom Elgin camshafts
• TWM throttle bodies with TIG air filters
• JB Racing stainless steel six-into-one headers
• MOTEC engine management system
• Sakata Motorsport Electronics wiring harness
• Carbon fiber engine cover
• Clewett Engineering serpentine fan belt kit
• Tarett Engineering solid engine mounts
• Tilton Engineering starter
• Denso CPN coils

The Porsche is equipped with a 915-style five-speed manual transaxle that has been fitted with a JB Racing lightweight three-disc clutch, a Guard Transmission billet main shaft, a Windrush Evolutions final drive housing equipped with a Guard Transmission limited-slip differential,and a Tilton Engineering differential oil cooler pump with an external cooler.

The cockpit houses an 8 point bolt-in chromoly cage, with tubular chassis reinforcements up front. The Sparco Pro ADV seat is FIA compliant through 2026. The Schroth racing harness is also good through 2026. Steering is through the quick-release Alcantara Momo steering wheel and Turbo tie rod ends. MOTEC engine management information is provided via the MOTEC digital dash unit mounted in carbon-fiber. Ignition switches and circuit breakers are also affixed to an aluminum dash panel. 

Suspension components include the following:

• RSR-style coilover front struts with raised spindles
• Custom-valved Bilstein shocks
• Eibach springs
• Tarett Engineering 935 control arm kit with crossmember
• ERP bump steer kit and spring plates
• Turbo tie rod ends
• Tarett Engineering camber plates and front sway bar
• Blade-type rear sway bar
• Rebel Racing upper spring hats with thrust bearings

Braking is supplied by Porsche Brembo Big Red calipers equipped with slotted front rotors and drilled rear discs.

The Porsche will also come with a spare set of wheels, a race radio system, log books, and a clean California title. An IMSA-style refueling rig with a Red Head style dry brake is also included in the sale.

This Porsch is a great buy, period. It is an even greater buy if you already have a spare Porsche race engine. You could bolt your spare in now and race, and build the other engine as you have time. That way you wind up with not only a spare engine, but a whole spare car – or one to sell. 

Another option might be for a race shop to buy the car, rebuild the engine, and then either use it as a rental car for clients/potential clients, or resale. 

Yet another option is to buy the car, buy an engine, bolt it in and go racing. An awful lot has already been invested in building and developing this Porsche race car. You are starting with a highly prepared chassis for a small fraction of its build and development costs. Add an engine and go race this very cool Porsche from Laguna to Daytona.
