Callaway Engineering completes its 500th Twin-Turbo Corvette conversion – Videos
Dateline: 9-26-15: Callaway Cars did something that no other outside vendor had ever done before or since for the Corvette line. From 1987 to 1991 Chevrolet offered, on the official Corvette order form, RPO B2K – Callaway Twin Turbo (not GM installed). RPO B2K started as a $19,995 option on top of the ’87 Corvette’s base price of $27,999, making it the most expensive option ever offered on a Corvette – a record that stood until the arrival of the $27,016, 1990 RPO ZR-1 option. The twin-turbocharged L98 engine was initially rated at 345-horsepower, up from the stock L98’s 240-horsepower. By 1991 the Callaway twin-turbo was rated at 403-horsepower.
The first Callaway Twin Turbo Corvettes sported twin NACA ducts on the hood and unique lightweight wheels. Later versions had full body kits designed by Paul Deutschman and are very unique-looking. After the 500th car was built, only 12 more were made. – Scott
