2012 Ecotec 2.0L I-4 VVT DI Turbo (LHU) for Buick Regal GS<\/p><\/div>\n

For 2012 models GM offers two tunes on the current LHU 2L Turbo:<\/p>\n\n\n\n\n\n\n\n\n\n
Applications:<\/td>\nHorsepower: hp ( kw )<\/td>\n<\/tr>\n
Buick Regal CXL<\/td>\n220 hp (164kW) @ 5300 RPM SAE CERTIFIED<\/td>\n<\/tr>\n
Buick Regal GS<\/td>\n270 hp (201kW) @ 5300 RPM SAE CERTIFIED<\/td>\n<\/tr>\n
Applications:<\/td>\nTorque: lb-ft. ( Nm )<\/td>\n<\/tr>\n
Buick Regal CXL<\/td>\n260 lb-ft (353Nm) @ 2000 RPM SAE CERTIFIED<\/td>\n<\/tr>\n
Buick Regal GS<\/td>\n295 lb-ft (400Nm) @ 2400 RPM SAE CERTIFIED<\/td>\n<\/tr>\n
Maximum Engine Speed:<\/td>\n6350 rpm ( forward gears )<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

The LTG 2L Turbo announced for the upcoming Cadillac ATS makes 270 hp and 260 lb-ft of torque.\u00a0 Compare to the N20 2L Turbo in the 2012 BMW 528i, which makes 240 horsepower and 260 lb-ft of torque.<\/p>\n

2013 Ecotec 2.0L I-4 VVT DI Turbo (LTG) for Cadillac ATS<\/p><\/div>\n

The current LHU engine has these features:<\/p>\n

DI ( direct injection )
\nDual-scroll turbocharger
\nDual CVCP (continuously variable cam phasing)
\nSodium-filled Iconel exhaust valves
\nAluminum pistons with jet-spray cooling
\nForged Powdered Metal (PM) connecting rods
\nForged Steel crankshaft
\nSemi-permanent-mold 356 Al cylinder head
\nVariable pressure fuel rail ( 50-150 bar )
\nStronger block bulkhead and deeper water jacket
\nCoil-on-plug ignition
\nDirect injection high-pressure multi hole injectors
\n58x engine position sensing
\nStainless steel fuel system components
\nDual converter system
\nCam driven high pressure fuel pump
\nMechanical brake vacuum pump<\/p>\n

and the new LTG engine features<\/a>:<\/p>\n

Among the 2.0T engine\u2019s highlights: a direct-injection twin-cam, four-valve-per-cylinder engine with continuously variable valve timing; twin-scroll turbocharger with air-to-air intercooler; forged-steel crankshaft with modular balance shaft system; and a two-stage variable-displacement oil pump with jet-spray piston cooling.<\/p><\/blockquote>\n

None of which spring forth as new compared to the current design.\u00a0 The current applications do have an air to air intercooler.<\/p>\n

Looking at the two engine images above, there are some clear differences in configurations.\u00a0 However, I wonder if the real secret of the new LTG 2L Turbo tune is that it can make 260 hp on regular unleaded instead of premium?\u00a0 The current LHU engine is “premium recommended, but not required; L85 capable”.\u00a0 Only needing regular unleaded would fit well with Cadillac’s tuning for the 3.6L to run on regular unleaded, and makes a nice bonus for the ATS.<\/p>\n","protected":false},"excerpt":{"rendered":"
