This 1975 Chevrolet Cosworth Vega is #12 of approximately 2,600 examples built for the model year and was acquired by the seller in 2000. A subsequent refurbishment included installing a 5.7-liter LS1 V8 and four-speed manual transmission, repainting the body in black, overhauling the brakes and suspension, and more as detailed below. Features include gold pinstriping, Hurst badging, 15″ alloy wheels, and a Hurst shifter. This Cosworth Vega is now offered with a clean Colorado title in the seller’s name.
The car is said to have been refinished in black circa 2005. Rust repair reportedly included replacing the battery box and spare tire well. Features include gold pinstriping, Hurst badging, and bright trim and bumpers. A later-model hood has been installed and the seller states that the windshield and weatherstripping have been replaced. Noted flaws include scuffs on the door and hatch moldings and scratches in the door glass.
Five-spoke 15″ wheels feature Hurst center caps and are wrapped in 205/55 Cooper Zeon 2XS tires. Four-wheel disc brakes were reportedly sourced from an S-10 pickup, and the seller states that the shocks were recently replaced and that the front end was recently overhauled.
The cabin is upholstered in black and features cloth seating surfaces and an engine-turned instrument bezel. Equipment includes a Hurst shifter, a heater, and an AM/FM radio. The transmission tunnel was cut to accommodate the shifter, and the seller notes that the replacement carpets are not installed properly and that the reverse lock-out on the shifter needs adjustment. A plaque affixed to the dashboard identifies the car as Cosworth Vega #12.
The four-spoke steering wheel features a Hurst horn button and frames a 120-mph speedometer, an 8k-rpm tachometer, and auxiliary gauges. The five-digit odometer shows 45k miles, approximately 30 of which have been added during current ownership. Total mileage is unknown.
The factory twin-cam inline-four was reportedly damaged during a theft in the 1980s. The currently installed 5.7-liter LS1 V8 is said to have been sourced from a 2000 Camaro and equipped with a Comp Cams camshaft. Custom valve covers have been fitted, and the transmission mounts were relocated to accommodate the larger engine. Additional service performed during the swap reportedly included seam welding the engine bay, installing an aftermarket exhaust system, and replacing the timing chain and oil pump. Dyno test results can be viewed in the gallery and show a maximum output of 324 horsepower and 345 lb-ft of torque.
Power is sent to the rear wheels through a four-speed manual transmission, and the seller states that a 3.73:1 Positraction rear end has been installed. Additional underside photos are presented in the gallery below.
