OHC-derived block with 86 mm bore & stroke and a Cosworth -developed DOHC Cylinder Head ( Cosworth Project KB). Cylinder heads were manufactured by Cosworth and Kolbenschmidt . In general, the heads from this engine family are supposed to flow appreciablу better than most Ecotec heads. Power output is rated at 110 kW (150 hp) @ 6000 rpm and 196 N·m @ 4600 rpm (C20XE) or 156 hp (20XE). Russia n car manufacturer AutoVAZ also used the C20XE in a limited-edition sports version of its Lada 110 model. This engine is used in:
X20XEV The first engine Opel branded as Ecotec, a mass-market successor to the C20XE with a Lotus -developed Cylinder Head . The new cylinder head had a smaller valve angle compared to the older C20XE, which was supposed to give more torque in the lower revs. It is a 1998 cc naturally aspirated engine with 16 valves and belt driven double overhead camshafts ( DOHC ). 86 mm bore and stroke in cast iron OHC -derived cylinder block and aluminium cylinder head. X20XEV was equipped with exhaust gas recirculation ( EGR ) to reduce nitrous oxide emissions and Air Injection Reactor (AIR) to speed up the warming up of the catalytic converter and to reduce unburnt Hydrocarbons and Carbon Monoxide . Power 100 kW / 136 hp. This engine was used in:
ECOTEC The Ecotec name was adopted in 2000 for the new generation of Family II engines. The name was already used for the Opel Family 1 and Family 0 ranges.

DI A high-end Direct Injection version of the 2.2 L Ecotec is available for: L61 ]] The basic Family II architecture was substantially reengineered in 2000, becoming the Ecotec 2.2, model '''L61''' (or '''L42''' for the CNG version). First appearing in the 2000 Saturn LS1 , the L61 spread throughout North American GM products, displacing the Quad 4 and its descendents. Unlike its notably harsh predecessor, the L61 was designed for smoothness. dual in-block Balance Shaft s were integral to the design, and all accessories were mounted directly to the engine block to reduce vibration. The oil filter was cast into the block with a removable cover and replaceable paper element. Displacement is 2.2 l (2189 cc) with an 86 mm (3.38 in) bore and 94.6 mm (3.72 in) stroke. Compression is 9.5:1 or 10:1, delivering 135 to 143 hp (101 to 107 kW) and 142 to 152 ft·lbf (193 to 206 N·m) of torque. The Ecotec line is manufactured in Tonawanda, New York , Kaiserslautern, Germany , and (for Saturn ) in Spring Hill, Tennessee . The L61-powered Saturn ION replaced the Saturn -powered Saturn S-Series . There are a few variations to the standard L61. The new . The Malibu and Saturn versions also use returnless Fuel Injection . In 2007 the L61 was upgraded with a second generation cylinder case, Coil on plug ignition, 58x crankshaft position sensing and a 32-bit computer. The 2.2 L Ecotec is used in the following cars:
Following the GM-Fiat agreement, the 2.2 L engine is also used in L42 The Ecotec 2.2, model '''L42''' is the CNG version of the Ecotec 2.2. It delivers 129 hp (96 kW) and 129 ft·lbf (175 N·m). LSJ ]] The LSJ is a de-stroked (to 86 mm) version of the L61 Ecotec with an Eaton M62 Roots-type Supercharger and air-to-liquid Intercooler . It is rated at 205 hp and 200 ft·lbf. With the end of the Chevy Cobalt SS and Saturn Ion Red Line, The LSJ will no longer be available in a production car after 2007. The LSJ was on the Ward's 10 Best Engines list for 2006. This engine is used in: LE5 ]] The LE5 is a larger 2.4 L (2384 cc) version of the Ecotec. Both the 88 mm bore and 98 mm stroke are larger, and Variable Valve Timing on the intake and exhaust improve low-end torque. Power is 164-177 hp (123-132 kW) and torque is 159-170 ft·lbf (215-230 N·m). The engine uses a reinforced "Gen II" block. The LE5 is also used in the following overseas models:
D-TEC/E-TEC II Holden makes various Family II engines for GM India and GM Daewoo at its Melbourne plant. Variations include displacements from 1.6 L. to 2.4 L. Unlike the Ecotec engines, the block is made of iron. L34 This is the 2.0L (1998cc) variant of the engines, featuring 86mm bore and 88mm stroke.
