The first version of this engine family was a normally aspirated 2.2 L (134 cu in) unit. Developed under the leadership of Chief Engineer – Engine Design and Development Willem Weertman and head of performance tuning Charles "Pete" Hagenbuch, who had worked on most of Chrysler's V-8 engines and the Chrysler Slant-6 engine, [1] it was introduced in the 1981 Dodge Aries, Dodge Omni, Plymouth ...

The Family II is a straight-4 piston engine that was originally developed by Opel in the 1970s, debuting in 1981.

The engine was discontinued in 2003, replaced by the 2.2-liter DOHC Ecotec engine. Although it displaces 134 cu. in, the 2.2-liter 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-body cars and S-series trucks, and a few L-body cars.
The new 9-3 departed from the Saab H / EcoPower engine used previously for a new 2.0 L straight-four Ecotec engine from General Motors' for the petrol-powered models. There are three different versions of the turbocharged inline-four, with the amount of turbo boost determining the power output: 1.8T (112 kW), 2.0t (131 kW) and 2.0T (157 kW).
The new engine was fitted with the ECU from the 2.4-liter engine. The 2.4-liter Ecotec received a similar upgrade: power increased by five horsepower to 175 hp (130 kW) at 6500 rpm, and torque increased from 162 lb⋅ft (220 N⋅m) to 164 lb⋅ft (222 N⋅m) at 4800 rpm .
The 2.0 engine was available in two different power outputs, badged by Vauxhall Di and DTi, the lower powered version retaining 16 valves and a turbocharger, but lacking the intercooler. [3] The lower powered 82 hp (61 kW) version was soon replaced by the smaller and unrelated 1.7 litre Circle L engine .
