crankshafts cast stainless steel exhaust manifold sand-cast gen3 block larger bosch injectors 0 261 500 112 with ethanol safe seals due to flex fuel compatibility Note: The A20NFT engine in Opel Astra K TCR car had swapped the original direct fuel injection into multi-point fuel injection. 2.2 L61 In 2007, the L61 received a multitude of changes, that originated from the LE5. It switched to the higher-strength Gen II block and received a revised cylinder head (enlarged exhaust ports) and camshaft design (increased exhaust valve duration). The engine also switched from wasted spark ignition to individual coil-on-plug ignition; this forced the cam cover to be redesigned. It was also switched to an E37 engine controller with new crank and cam sensors (replacing timing sensor previously found in ignition cassette). These changes increase horsepower slightly and allow the engine to meet PZEV standards. Compression ratio is 10.0:1. The L61 was used in the following cars: LAP The LAP is a version of the Ecotec, based on the Gen II block with cylinder head improvements, new camshaft design, E37 engine control module, 58X crankshaft reluctor ring, dual variable valve timing, digital crank and cam sensors, individual coil-on-plug ignition, vented starter solenoid, new MAP sensor, new intake manifold seals, new oil filter element, a 32-bit computer, and improved emissions performance. Bore and stroke are and , the same as the 2.2 L L61. Compression ratio is 10.0:1. Major features that set it apart from the 2.2 L L61 are variable-valve-timing and other cylinder head improvements from the 2.4 L LE5. LE8 The LE8 is an E85 compatible version of the LAP Ecotec. Bore and stroke remain the same and . Compression ratio is 10.0:1 and the engine can run on both regular unleaded gasoline or E85. 2.4 LE5 The LE5 is a larger version of the Ecotec. Both the bore and stroke are larger, and Variable Valve Timing on the intake and exhaust improve low-end torque. Compression is 10.4:1. Power is 164–177 hp (123–132 kW) and torque is 159–170 lb·ft (215–230 N·m). The engine uses a reinforced "Gen II" block. Connecting Rods are GKN Forged. C70 Powdered Metal from July 2007 on. The LE5 is also used in the following overseas models: 2006 GM Taiwan Buick LaCrosse 2006 Shanghai GM Buick LaCrosse Buick GL8 The LE5 or a close variant is also used in the Polaris Slingshot (announced July 27, 2014), coupled with
