The Chevy 2.2L/134 cid is the latest in a family of engines that had its beginnings in the 1982 Cavalier, Chevy’s new "J" car that came with an all new 1.8L/112 cid engine. Unfortunately, this four cylinder, pushrod motor didn’t have nearly enough horsepower, so Buick, Oldsmobile and Pontiac all opted for the 1.8L SOHC Opel engine from Brazil for most of their "J" cars, and Chevy promptly made its new engine into a 2.0L/121 cid that delivered more power in 1983.
The 2.0L was upgraded in 1987 with the addition of an aluminum head and crank-triggered spark along with a longer rod and a shorter, lighter piston that reduced noise, vibration and harshness (NVH). GM called it one of its "Generation II" engines.
In 1990, the stroke was increased from 3.15" to 3.46" to make the 2.0L into a 2.2L. Since then, the block has been revised four times, and the head has been changed three times.
Beginning in 1994, when the 2.2L became the base engine in the small pickups, there were some more subtle differences, too, so there are a total of seven different long blocks and plenty of opportunities to mess up if you don’t know where to look.
