This 1981 911SC has been modified with 964 RSR-style bodywork, a 964 flat-six displacing 3.8 liters, and a race-prepped interior featuring Cobra seats, harnesses, a welded-in cage, and a fire suppression system. Power is sent to the rear wheels via a 5-speed manual transaxle fitted with racing gears and a limited-slip differential, while further additions include 18″ Kinesis 3-piece wheels, JRZ coilovers, 993 Turbo front brakes, and 930 rear brakes. The build was reportedly completed for the original owner in 2014, and the car was acquired by the current owner in 2017. This 964-powered 911SC is offered by the seller on behalf of a friend with a clean Carfax and a clean California title. The car was painted silver in 2014 and is fitted with a 964-style fiberglass hood, bumpers, and front fenders as well as bolt-on rocker panels and a 993 RS-style rear wing. Fiberglass doors were replaced with standard versions equipped with powered windows under current ownership. The headlights have been converted to European specification, and 964 aero mirrors are fitted. Chips and scratches can be seen on the front spoiler, bumper, and rocker panels. Kinesis 3-piece 18″ wheels are mounted on studs and wear Toyo Proxes R888 tires showing 2017 date codes. The suspension has reportedly been modified with JRZ coilovers, while braking is from drilled rotors with 993 Turbo front calipers and 930 rears. The race-prepped interior is trimmed with Porsche-branded upholstery on Cobra Suzuka racing seats and custom door panels. A welded-in cage features crossbars behind the seats and in the door openings. A fire suppression trigger is mounted to the right of the 964 RSR-style steering wheel. Instrumentation includes a 964 tachometer, tilted 3.2 Carrera speedometer, and SC supplementary gauges. Just under 73k miles are shown on the 5-digit odometer, with total mileage unknown. The current owner reportedly installed a new air conditioning compressor and hoses in March 2018. The front trunk is equipped with a 19-gallon Fuel Safe racing fuel cell, a battery shut-off switch, a brake bias valve, and welded-in bracing between the strut towers. The 964 flat-six is said to displace 3.8 liters and is paired with a 5-speed 915 transaxle reportedly overhauled with racing gears, an 8:31 final drive, and a reconditioned ZF limited-slip differential as well as a Wevo shifter. The build is said to have been carried out by Stuttgart Auto Service of Walnut, California, though supporting records are unavailable. The car has been reportedly tracked for 40 hours since the latest overhaul, and the seller states that the owner has tuned the engine and changed the oil and filter. The exhaust system is not fitted with a catalytic converter. The Carfax report shows no accidents or damage between 1996 and 2002, with no further entries listed.
