GM 2.0 ECOTEC FORCED INDUCTION LINE

The GM Ecotec engine, also known by its codename L850, is a family of all-aluminium inline-four engines, displacing between 2.0 and 2.5 litres. While these engines were based on the GM Family II engine, the architecture was substantially re-engineered for the new Ecotec application produced since 2000. This engine family replaced the GM Family II engine, the GM 122 engine, the Saab H engine, and the Quad 4 engine.

GM 2.0 ECOTEC LK9

This engine is also known as B207 when used by Saab and Z20NET by Opel for use in the Vectra C and Signum. LK9 is a turbocharged 2.0 L— 1,998 cc (121.9 cu in)—version of the L850 (86 mm bore) series Ecotec utilizing an all-new reinforced sand cast aluminum cylinder head and upgraded internal components. The exhaust valves are liquid sodium-cooled. In Saab vehicles, this engines features Saab's Trionic 8 engine management system as well as a revised valve train. The timing chain and timing gears are also new, along with Saab's Direct Ignition system. The reinforcements, turbocharging, intercooling, internals, dual overhead camshaft, and such were developed by GM Powertrain Sweden (Saab Automobile Powertrain). It features an 86 millimetres (3.4 in) bore and stroke and a 9.5:1 compression ratio. Maximum power is 210 horsepower (160 kW) at 5300 rpm and 221 lb·ft (300 N·m) of torque at 2500 rpm. Maximum boost is 12.3 psi (0.85 bar).[WIKI]

GM 2.0 ECOTEC LSJ

The LSJ is a supercharged version of the LK9 Ecotec 2.0 L— 1,998 cc (121.9 cu in)— with an Eaton M62 Roots-type supercharger and air-to-liquid intercooler. The LSJ shares many of its components with the LK9 such as: piston cooling jets, oil cooler, pistons, connecting rods, crankshaft, oil pan, sodium-filled exhaust valves and cylinder head.[8] It is rated at 205 hp (153 kW) at 5600 rpm and 200 lb·ft (271 N·m) at 4400 rpm with a compression ratio of 9.5:1 and a 6500 rpm redline. With the end of the Chevy Cobalt S/C SS and Saturn Ion Red Line, the LSJ was discontinued after 2007. In late 2005 Brammo Motorsports struck a deal with GM for the Supercharged 2.0 L Ecotec for their Ariel Atom. The engine came in various ratings from 205 hp (153 kW) to 300 hp (220 kW). The LSJ was on the Ward's 10 Best Engines list for 2006.[WIKI]

GM 2.0 ECOTEC LNF

A turbocharged direct injected (redubbed Spark Ignition Direct Injection) Ecotec was introduced in the 2007 Pontiac Solstice GXP and Saturn Sky Red Line. In these applications, the engine is mounted longitudinally. Displacement is 2.0 L—1,998 cc (121.9 cu in)—with a square 86 millimetres (3.4 in) bore and stroke. Compression is 9.2:1 and maximum boost is 1.4 bar (20.0 psi), delivering 260 hp (190 kW) at 5300 rpm and 260 lb·ft (350 N·m) of torque from 2500 to 5250 rpm. Engine redline is at 6300 rpm and premium fuel is recommended. The sodium filled exhaust valves were based on technology developed for the Corvette V8 powertrains. The sodium fuses and becomes a liquid at idle, which improves conductivity and draws heat away from the valve face and valve guide towards the stem to be cooled by the engine oil circulating in this area. The camshaft-driven direct injection systems pressurizes the fuel to 31 bar (450 psi) at idle, and up to 155 bar (2,250 psi) at wide-open throttle. The "Gen II" block is similar to the 2.4 L and also features VVT technology. The Gen II block was developed using data from racing programs and computer simulations. The bore walls and bulkheads were strengthened with a weight increase of 1 kg (2.5 pounds). The coolant jackets were expanded to improve heat transfer, resulting in a coolant capacity increase of 0.5 liters. In December 2008, GM released a Turbo Upgrade Kit for the LNF engine which increases horsepower to 290 hp (220 kW) and torque to up to 340 lb·ft (460 N·m), depending on the model. The kit retails for $650 and includes remapped engine calibration and upgraded MAP sensors. The kit is covered by the cars' existing GM warranties.[10] This was the final Stage 2 performance tune the Ecotec family, to date. With the demise of the GM Performance Division, performance tunes like this have been relegated to the aftermarket sector. This despite newer engines being more durable, and tuned to lower horsepower levels in numerous sport-car applications.[WIKI]
