Porsche 911s - Racecar Conversion - Twin Plug

Looking to trade this for another Porsche or BMW, street legal, my track days are limited and I hate seeing this collecting dust, I'm not interested in projects for a trade, 718-Boxster/Cayman GTS/997conv/991conv/BMWm4conv or similar is high on my radar.

The 1974 Porsche 911 available for sale has undergone significant track-focused modifications under prior ownership. It now boasts a fiberglass 993-style wide body finished in a striking yellow and blue color scheme. The vehicle is powered by a 2.8-liter flat-six engine with twin-plug cylinder heads, mated to a six-speed manual transaxle. Its track history includes participation in Porsche Club of America driver education events in the past, and since the current owner acquired it in 2008, it has been actively raced in National Auto Sport Association events. Notable features include a roll cage, plexiglass windows, an onboard fire-suppression system, a Recaro racing seat, 17-inch CCW wheels, 996 Turbo disc brakes, adjustable coil overs, a Coolshirt system, and an AiM digital dashboard. This Porsche 911 race car is now available, a removable muffler system, and a bill of sale.

The vehicle's fiberglass 993-style bodywork, featuring the distinctive yellow and blue #859 livery, was installed on the original 1974 chassis during a previous ownership period. Notable exterior components include plexiglass windows, front and rear tow hooks, detachable front body panels, a removable rear engine cover, and an integrated rear spoiler with a carbon fiber rear wing.

The car is equipped with staggered 17-inch CCW wheels wrapped in Hoosier slick tires, measuring 245/40 in the front and 315/35 in the rear. Additional enhancements include drilled and ventilated disc brakes borrowed from a 996 Turbo, front brake cooling ducts, and adjustable coil overs on all four corners. The seller reports that in 2020, the car underwent service that included the replacement of front brake rotors and wheel bearings. Alongside the vehicle, two extra sets of wheels are said to be included.

Inside, the interior features a comprehensive roll cage, a Recaro fixed-back driver's seat, and a six-point harness and window net installed in 2020. Additional equipment comprises a Tilton pedal assembly, an onboard fire-suppression system, a Coolshirt system, a brake bias adjuster knob, and dash-mounted rocker switches. The steering wheel is a MOMO quick-release unit, and the car features an AiM digital dashboard with supplementary instrumentation, including a shift light, fuel level gauge, oil temperature gauge, and air/fuel ratio gauge. The mileage of the vehicle is not specified.

The 2.8-liter flat-six engine was reportedly constructed by Dawes Motorsports and boasts twin-plug cylinder heads along with dual MSD digital 6AL ignition controllers. The engine underwent a rebuild in 2020 and has subsequently seen approximately twenty hours of track usage, oil changed after each track weekend. Power is transmitted to the rear wheels through a G50 six-speed manual transaxle, and a custom stainless exhaust system is equipped with removable mufflers and turn-down outlets. The seller notes that the clutch and flywheel were replaced in 2019, and the gearbox was rebuilt during their ownership with closer-ratio gears.
