became the last engine available on an American-sold vehicle to use throttle body injection for fuel delivery. Through the 1985-1991 model years a turbocharged MPFI version of the G10 was offered in some markets. This engine delivered at 5500 rpm and at 3500 rpm. This turbocharged engine, with mechanical lifters, was available in both the US and Canadian Firefly/Sprint/Forsa from 1987-88. Only the Canadian Firefly/Sprint had this option, with hydraulic lifters, in the 1989-1991 model years. In the Japanese domestic market, the car was originally carbureted ( JIS at 5500 rpm, at 3500 rpm) and went on sale in June 1984. In October 1987, along with a facelift, the home market Turbo received fuel injection and power output went up to JIS, torque to . It was a short-lived version, however, as by September 1988 the car was no longer on sale in the Japanese domestic market.
