Powered by the legendary 5.7L LS6 V8, the C5 Z06 was engineered as a no-compromise driver's car, featuring reduced weight, upgraded suspension, and track-bred performance that helped redefine what an American sports car could be. From the factory, these cars were already special, this example takes it several steps further.This Z06 has been thoughtfully and professionally upgraded, with major performance work completed in 2023 by Koza Motorsports. Featuring a cammed LS6, ceramic-coated headers, X-pipe, Billy Boat axle-back exhaust, upgraded intake, and a fresh clutch and flywheel, the car delivers an aggressive sound and serious performance. Dyno results show 421 wheel horsepower, well beyond stock while retaining drivability and reliability. All supporting systems were addressed at the same time, including gaskets, sensors, belts, hoses, fluids, and hardware.Inside, the car blends modern tech with original charm. A full audio overhaul completed in 2021 includes a Kenwood double-DIN head unit with Apple CarPlay and Android Auto, Alpine amplification, and Maximo speakers. For collectors and purists, this Z06 also includes an impressive selection of original items such as the second factory key, original manuals and pens, sealed VHS overview tape, original shift knob, and factory speaker boxes, rarely seen together today.Mechanically sorted and well maintained, this Z06 runs flawlessly and benefits from a new A/C system installed in 2024 and a recent oil change in 2025. With its raw LS power, unmistakable cammed idle, and strong documentation, this 2002 Corvette Z06 offers an exciting opportunity to own a properly built modern American performance icon that's equally at home on the street or at a weekend car event.
