[QUOTE="patooyee, post: 375033, member: 483"] I think this is the one I would want due to power, torque curve, availability and price. LNF[edit] Ecotec LNF in a Pontiac Solstice 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.[5] Unique LNF features[6] include: a twin-scroll turbocharger cam-driven high-pressure gasoline direct injection fuel system dual camshaft continuously variable valve timing sodium-filled stainless steel Inconel exhaust valves low-friction cast aluminum pistons with oil squirters forged steel crankshaft forged steel connecting rods cast stainless steel exhaust manifold This engine is used in: Year(s) Model Power Torque 2007–2009 Opel GT 260 hp (190 kW) @ 5300 rpm 260 lb·ft (353 N·m) @ 2000 rpm 2007–2009 Pontiac Solstice GXP 260 hp (190 kW) @ 5300 rpm 260 lb·ft (353 N·m) @ 2000 rpm 2007–2009 Saturn Sky Red Line 260 hp (190 kW) @ 5300 rpm 260 lb·ft (353 N·m) @ 2000 rpm 2008–2010 Chevrolet HHR SS 260 hp (190 kW) @ 5300 rpm 260 lb·ft (353 N·m) @ 2000 rpm 2008–2010 Chevrolet Cobalt SS 260 hp (190 kW) @ 5300 rpm 260 lb·ft (353 N·m) @ 2000 rpm 2009 Elfin T5 264 hp (197 kW) @ 5300 rpm 259 lb·ft (351 N·m) @ 2000 rpm 2012 Fisker Karma 260 hp (190 kW) @ 5300 rpm 260 lb·ft (353 N·m) @ 2000 rpm [/QUOTE]
