1987 Callaway Corvette B2K Twin Turbo Gallery

Offered from 1987 to 1991, the RPO-B2K upgrade was available from any Chevrolet dealer and also Callaway’s first major Corvette tuning program.

The B2K option was primarily an engine upgrade, but was comprehensive and used over 2000 new parts. The engine itself got new forged pistons, crankshaft, better lubrication system and four bolt main bearing caps. The induction system required a secondary injection system to retain the original emissions and fuel injection system.
