This Car

The Porsche 911 presented here owes its exceptional specification and distinctive appearance to its current owner – Los Angeles based Porsche enthusiast Magnus Walker. A prominent figure in the Porsche community, Walker maintains an impressive stable of 911s – ranging from a rare 1964 model to early 930s – each car bearing his unmistakable imprimatur. Following in the tradition of Southern California hot rod builders, Walker creates highly individualized cars that, while immediately retaining the appearance of a classic 911, abound in personalized details and the finest high-performance components.

This car, dubbed the 911 “STR II,” was originally constructed as a Gemini Blue 1972 911 T. Discovered in Sacramento, this Porsche was an ideal candidate for restoration and was selected for its one-year-only external oil filler, rugged Type 915 gearbox, and potent 2.4-liter engine.

Inspired by 911 race cars of the early 1970s, the “STR II” is a brilliant amalgam of Porsche’s famed ST and R models that combines early short-wheelbase details with Walker’s preferred custom touches.

In creating an aggressive, track-ready appearance, the “STR II” incorporates re-profiled SC and Turbo fender flares, neatly integrated 911 R-style indicator lights, an outside fuel filler, lightweight fiberglass bumpers, and Campagnolostyle Group 4 PAG wheels shod with Hoosier R6 tires. Among the many custom features, a louvered rear deck lid, Plexiglas bubble quarter windows, and drilled door handles are Walker’s favorite details. Finished in a splendid tri-color livery with white bodywork, orange bumpers, and blue hood stripes, the “STR II” is a subtle homage to the legendary Gulf 917s of the era.

In keeping with the car’s outward appearance, the competition-oriented interior is equipped with a period-correct bolt-in roll bar, Recaro rally seats, Schroth harnesses, drilled floorboards, a J-West Rennshifter, and a Racemark steering wheel. The addition of a 917-inspired Balsa wood shift knob, a Heuer clock, chrome gauge bezels, and a short-wheelbase rearview mirror add to the overall presentation and give the car a unique personality.

Designed as a “street car with track aspirations,” the “STR II” makes use of a 3.2-liter short-stroke engine based on a three-liter SC case. Built by Porsche specialist Rennwerks of Camarillo, California, the engine incorporates JE Pistons, a high-lift Mod S cam, ARP connecting rod bolts, AASCO racing valve springs, stainless valves, and Bosch mechanical fuel injection. Breathing through 1 5/8" headers and an M&K twin pipe muffler, this 911 makes an unforgettable noise.

This potent engine is kept cool by a frontmounted Carrera oil cooler with Elephant racing finned oil lines and it delivers power to the rear wheels through a Team VDS-built 915 gearbox equipped with a limited-slip differential. Tipping the scales at less than 2,200 lbs. and generating approximately 275 bhp from its 3.2-liter engine, this 1972 911 has a power-to-weight ratio comparable to Porsche’s brand-new 991.

In the effort of creating a well-rounded package, the suspension has been thoughtfully upgraded with quick-change torsion bars, adjustable spring plates, RSR-style adjustable sway bars and strut mounts, Bilstein sport shocks, turbo tie rods, sealed monoballs, raised spindles, 80 mm wheel studs, and a bump steer kit.

Described by Walker as the car “I’m most proud of and definitely my best build to date,” the recently completed “STR II” has garnered widespread acclaim, from Porsche aficionados and high-profile collectors alike. Perhaps the greatest testament to this car’s appeal is the fact that it was selected to appear on the cover of Road & Track in June 2013 as part of a special issue celebrating the 50th anniversary of the Porsche 911. Beyond this impressive feature, Walker’s “STR II” was the subject of a featured article in Total 911: The Porsche Magazine titled, “The New Legend,” and it has been showcased on Fifth Gear, Adam Carolla’s CarCast, and Jay Leno’s Garage.

Offered from Magnus Walker’s collection, the “STR II” represents an exciting opportunity for the collector in search of a unique and much-admired variation on the classic Porsche 911.
