1991 Callaway Corvette

Callaway produced 508 twin turbo cars between 1986 and 1991. The twin turbo car could be ordered direct from the Chevrolet dealership by checking RPO B2K. The B2K option was an engine-option-only at a $33,000 adder with body, paint and suspension options being additional. Among the engine configurations were the 403 hp version which offered nearly 600 lb ft of torque

In 1991, at the Los Angeles Auto Show, Reeves Callaway introduced a Speedster version of the Chevy Corvette. The vehicle gracing the display was a green ZR1 that had several modifications both mechanically and cosmetically. The green ZR1 had a chopped windscreen, a blue leather interior, rode on 18-inch wheels, and had no side mirrors. Equally impressive was the twin-turbocharged engine that offered an astonishing 450 horsepower.

To cope with the turbochargers, the Speedster was given a competition suspension with coil overs, and adjustable shocks. Stopping power was provided by Brembo brakes which gripped 17-inch 3-piece OZ racing wheels. The prototype car, chassis number 000, had 18-inch wheels.

The Speedster was designed by Paul Deutschman. The carbon fiber body had twin power bulges which aligned with the headrests. There was no top - it was an open bodied car. In the front were special air inlets to provide air to the intercoolers.

Callaway planned on producing 50 examples, though only 12 units were ever produced. Pricing was around $150,000.
