This 1981 Porsche 911SC Targa was modified under prior ownership with a 3.6-liter M64 flat-six engine paired with a rebuilt 5-speed 915 manual gearbox. Professionally refinished in Guards Red over a black interior, the car also features upgraded air conditioning, GIAC performance software, a short shifter, enhanced brakes and suspension, an M&K exhaust system, and more. Acquired by the seller in May 2023 from the previous owner of approximately 18 years, this example has since received additional maintenance and is now being offered for auction out of Virginia accompanied by extensive build documentation.
The exterior received a full glass-out refinish in Guards Red and seal replacements at a Porsche dealership in March 2007 at 97,463 miles. Equipment includes a black Targa bar with a removable roof panel, upgraded H4 headlights, a custom lower front valance with integrated fog lights, black quarter panel stone guards, European-style rear bumperettes, and a rear whale tail spoiler. Under current ownership, 17" Maxilight Fuchs-style wheels were installed, measuring 8” wide in front and 9” in the rear, mounted with new Continental Sport tires sized 225/45ZR17 and 255/40ZR17, respectively. New Porsche crest center caps were also fitted, and the Targa latches were replaced. Detailed images are provided in the gallery along with a damage-free CARFAX report.
Inside, the cabin features black upholstery and aftermarket front bucket seats. Audio upgrades include an Alpine CDA-9815 head unit with aux input compatibility, a Pioneer 400W MOSFET amplifier, and Infinity Reference 6"x9" and 6" speakers. The heat system remains fully functional with Carrera-style footwell blowers and a 3-speed fan bypass switch on the engine. Air conditioning has been updated with a 964-style compressor and a Griffith kit for R134 refrigerant. The pedal assembly and shift coupling were reportedly rebuilt using brass bushings. Upon the seller's acquisition, a MOMO steering wheel was installed, and the carpet was removed and replaced with a black plush OEM-style set sourced from Pelican Parts.
Under previous ownership, a 993-sourced 3.6-liter flat-six engine was installed in 2007, paired with a rebuilt 5-speed 915 manual transmission featuring a Patrick Motorsports lightweight flywheel, a Sachs Power clutch kit, and a short shifter. The engine was reportedly overhauled and modified in 2004 with Bosch Motronic engine management, twin-plug ignition, a GIAC ECU chip, and an M&K exhaust system. The battery was replaced in 2023, and the engine compartment insulation has been removed. A host of build documentation is provided in the gallery, additional mechanical modifications under prior ownership include the following:
This sale will include a clean title, a toolkit, a spare tire, a car cover, and documents showing the technical specifications for engine conversion & other mechanical modifications.
The seller would like you to know: “This 1981 911SC Targa has been extensively modified with a 993 engine, upgraded suspension, improved braking and cooling systems, and a modernized air conditioning setup—making it a joy to drive. It’s fast, stable, and well-balanced, offering performance comparable to much newer non-air-cooled 911s, while remaining lightweight and engaging. The cabin is comfortable, with strong heat via the footwell blower, a quality sound system, and upgraded cold A/C. Finished in shiny Guards Red (code 027) over a black interior, it sits with a great stance on 17" Fuchs-style wheels. It sounds fantastic, has no known leaks, and is in excellent mechanical and engine condition.”

Thank you for your comment.
Yes this build was done very professionally & the engine is just fantastic. Works like clock. Vey smooth and loves to rev. Everything else on the car is functional & in good shape with updated Cold AC.
I have multiple Porsche , BMW & Mercedes. Given my age & health condition, I decided to keep one of each. So Vey tough decision between this & the 84 Euro 930 Slant nose that I bought here at Pcar s few years ago. It is just absolutely beautiful. The Traga has a more modern engine and better acceleration. But when the Turbo kicks in the slant nose 930 feels like a whole different car with 335 tires in the bac
I did intend to keep the Targa and that's why I changed to Fuchs wheels & a classic Porsche steering wheel. It needs nothing & starts right up every time & sounds amazing like a race engine .
Among my BMW's the choice is clear . just finished a multi year & very expensive restoration of a 1972 Euro E9. 3.0 CSI. Which is now 3.7 M90 with Megasquirt.
Beautiful car. With so many of these all hacked up it is great to see a car where everything fits together. Why sell it?

Very smooth with lots of power. Loves to rev up there!
Engine sounds amazing. Very nice SC Targa.
There are 3 big binders of records and manuals related to this build covering, engine, electrical, ecu, wiring harness, suspension, clutch transmission and etc.
Engine is very strong and runs perfectly. I did not need to do compression or leak . Not too many mikes since complete engine rebuild.
Down test. Clutch is fine
Hi, nice looking SC. Would you have any compression/leak down figures? Any other records of repairs/maintenance? How about the clutch?
