Formula Pacific was a motor racing category which was used in the Pacific Basin area from 1977 to 1982. It specified a single-seat, open-wheeler chassis powered by a production-based four-cylinder engine of under 1600cc capacity.[1] The formula was based on Formula Atlantic, with provision made for the use of Japanese engines. The category was superseded in 1983 by Formula Mondial, which was devised by the FIA to replace both Formula Atlantic and Formula Pacific.
