GM 122 Engine - 2.2L/2200 OHV

2.2L/2200 OHV

For the 1990 model year GM replaced the 2.0 L engine with a bored and stroked version displacing 2.2 L. Known as the 2.2 from 1990 to 1997 and the 2200 from 1998 on, it used throttle body fuel injection and produced 95 horsepower (71 kW) and 120 lb·ft (163 N·m) of torque. For 1992 multi-port fuel injection replaced the old throttle body injected version in the J-body cars increasing power to 110 horsepower (82 kW) and torque to 130 lb·ft (176 N·m). In the L-body cars it was converted straight to Sequential Fuel injection. In 1994 all 2.2L engines were updated to Sequential MPFI and power increased to 120 horsepower (89 kW) with torque increasing to 140 lb·ft (190 N·m). The MPFI and SFI versions produced enough power to allow the 2200 to replace the old Pontiac Iron Duke engine as the 4-cylinder offering in the S/T platform trucks and A-body cars. A final revision to the 2200 occurred when emissions updates were done in 1998 lowering power and torque to 115 horsepower (86 kW) and 135 lb·ft (183 N·m) respectively. The 2200 was discontinued in 2003, replaced by the 2.2L DOHC Ecotec engine. Although it displaces 134 cu. in, the 2.2L OHV is still commonly referred to as the GM 122 today, and has been reputed for its simplicity, reliability and ease of maintenance in the J and L-body cars and S-Series Trucks.
