A heavily modified 1989 Porsche 944 Turbo built for competitive track use is drawing attention as it heads to auction in Michigan, offering racing enthusiasts an opportunity to acquire a purpose-built Porsche Club of America competition car.The vehicle, located in Marine City, Michigan, is being offered without reserve and represents the final production year of the 944 Turbo, a model widely recognized for combining turbocharged performance with the balanced handling characteristics of Porsche's transaxle-era sports cars.Showing approximately 63,600 miles, the car has been transformed from a street-driven sports coupe into a dedicated track machine configured to compete in Porsche Club of America SP3-class racing. Power comes from a turbocharged 2.5-liter inline-four engine paired with a five-speed manual transaxle and limited-slip differential, maintaining the layout that helped establish the 944 Turbo as a favorite among amateur racers and club competitors.AdvertisementAdvertisementThe car's current appearance is highlighted by a removable Rothmans-inspired white-and-blue vinyl wrap covering its original gold finish. Aerodynamic enhancements include a GOODAero Raptor rear wing, front splitter, air dam, fiberglass hood and cooling modifications integrated into the front fascia. Additional weight-saving measures include plexiglass components for both the windshield and rear hatch, along with a manual headlight conversion.Mechanical upgrades extend throughout the chassis.

A MOTON three-way adjustable coilover setup, Hypercoils springs, billet control arms and specialized racing suspension hardware have been installed to improve handling and track performance.Inside, the transformation is even more apparent. The interior has been stripped for competition use and fitted with Recaro racing seats, a full roll cage, racing harnesses, a MOMO steering wheel with quick-release hub and a MOMO Motorsport shifter. Additional track-focused equipment includes a Traqmate data acquisition system, shift light, fire extinguisher, boost gauge and window net.Performance modifications to the powertrain include an ECU tune, upgraded wastegate, aftermarket throttle position sensor, custom exhaust system and lightweight Odyssey battery.
