1973 Porsche 911T Twin-Plug Outlaw

Offered for sale by K2 Motorcars is this incredible modified, non-sunroof 1973 Porsche 911T Twin-Plug Outlaw car built with guidance from Magnus Walker. The previous owner acquired the car in 2013 after it had been placed on consignment by Brian Cunningham, grandson of American racing icon Briggs Cunningham. Power is provided by a fuel-injected, twin-plug, 2.8L flat-six, which was built by TLG Auto using the original case and is mated to a 915 transaxle equipped with Guard limited-slip differential. The car is finished in Gemini Blue and features rear fender flares, gold exterior accents, a louvered rear decklid, fifteen52 Outlaw wheels, and suspension refurbished by TLG using Elephant Racing parts. The interior is equipped with Recaro sport seats, a roll bar, and a custom fiberglass dash made by Rod Emory. This 911T is now offered with a Porsche Certificate of Authenticity, records from the build, and a clean Florida title.

Originally Gold Metallic, the car had already been repainted in Gemini Blue when it was acquired by the previous owner. Magnus Walker is friend of the previous owner and provided creative direction on the subsequent modifications, which included installation of a custom louvered rear decklid, as well as fitment and metal work performed by Rod Emory. Scuffs are present on the underside of the front bumper, and sandblasting is visible in the finish near the wheel arches.

The car is equipped with rear fender flares, as well as an oil cooler mounted in the passenger-side front wheel well. Magnus Walkers painter added stripes in the factory Gold Metallic color on the front and rear lids. Additional features include European-style headlight rings, a 911S-style front spoiler, a dual-outlet sport exhaust, and gold Porsche side script.

The Fifteen52 Outlaw 001 two-piece forged wheels were ordered by Magnus Walker for the previous owner with a custom matte finish as shown on an invoice included in the records. The 157 #8243; fronts feature an offset of ET23, while the 158 #8243; rears have an offset of ET10. Pirelli Cinturato P7 tires measure 205/50 up front and 225/50 out back.

Recaro sport seats are upholstered in black, and the cabin is also equipped with a four-point, bolt-in roll bar. The rear seatbacks have been removed, and lightweight door panels are fitted. The amber fiberglass dash was made by Rod Emory, and other interior modifications include a 917-style wood shift knob and a leather-wrapped MOMO Prototipo steering wheel. Silver-dot VDO instrumentation includes a centrally-mounted 8k-rpm tachometer, 150-mph speedometer, oil, and fuel level gauge, oil pressure/temperature gauge, and an analog clock. The odometer was reset during the build, and approximately 5,400 miles have been added since.
The injected flat-six engine was rebuilt and modified by TLG using the original 2.4L case. It now displaces 2.8 liters and is equipped with twin-plug cylinder heads. It reportedly produced 220 horsepower at the rear wheels during dyno tuning, which is sent to the rear wheels via a Type 915 five-speed manual transmission. The gearbox is equipped with a Guard limited-slip differential and was recently rebuilt and strengthened by Marty Mehterian.

Stamping *6130800* is pictured above and corresponds to the number shown on the Porsche CoA, confirming the originality of the engine case. The transmission carries number 7333419, which indicates a short-ratio gearbox produced in 1973.

TLG removed the suspension from the car for refurbishment and fitted an Elephant Racing adjustable bump steer kit, Bilstein Sport dampers, 22mm front torsion bars, 27mm rear torsion bars, adjustable rear spring plates, and new bushings.

A sample of receipts from Emory Motorsports, fifteen52, and TLG Auto are shown in the gallery, including records for more than $51k in work from the latter. The Porsche Certificate of Authenticity shows the factory colors, equipment, and powertrain numbers.
