History and trivia
The second-generation RX-7, internally known as the FC (1985-1992), replaced the original SA22/FB with a more grand-touring-oriented approach, featuring a rounder body and a more refined chassis, moving away from the stripped-down sports-car character of the first model. Mechanically, the big news was a turbocharged version of the twin-rotor 13B engine, which in Japan even used a sequential twin-turbo system to reduce lag, an unusual solution for a rotary engine at the time.
Outside Japan, the RX-7 FC competed successfully in American racing categories such as IMSA GTU and GTO, building Mazda's motorsport reputation well before the historic overall win by the RX-7-derived 787B at the 1991 24 Hours of Le Mans. Today the FC is highly regarded within JDM and tuning culture for how easily its rotary engine can be modified, though its popularity has been somewhat overshadowed by the third generation, the FD3S, which many enthusiasts consider the definitive RX-7.
