The ECOTEC 2.0L turbo four-cylinder engine carries the legacy of an engine recognized as one of

Ward’s 10 Best Engines in 2012. Although it shares the same displacement as the previous turbo

engines, it is a next-generation architecture with friction-reduction technologies designed to

enhance refinements on a variety of levels. The turbocharger features a twin-scroll design that

uses exhaust tuning to balance maximum power and excellent turbo response, enabling the

engine to deliver its broad torque band. It also supports the responsiveness associated with larger-

displacement, naturally aspirated performance engines.

Gen II Engine Block• Turbo sand-cast cylinder block is a superior refinement of previous ECOTEC

engine block castings that provides improved structural support and greater

control of noise, vibration, and harshness.

• The main bearing bulkheads, which support the crank bearings and the cylinder

bore walls, are strengthened to support increased engine loads.

Rotating Assembly• The crankshaft is made of forged steel with induction heat-treated fillets and

cross-drilled chamfered oil passages for racing-grade lubrication characteristics.

• Forged powdered-metal connecting rods incorporate a larger, forged I-beam

cross section for added strength.

• The pistons are lightweight cast aluminum to enhance efficiency and

performance as the rpm increases. Individual jet sprays provide an additional

layer of lubricant on the skirt’s underside and cylinder wall, reducing friction

and operational noise, and bolstering the engine’s durability.

Rotocast Aluminum Cylinder Head with Sodium-Filled Exhaust Valves• Aluminum cylinder head is cast using a Rotocast process for high strength,

reduced machining, and improved port flow.

• Designed specifically for direct injection.

• Stainless steel intake valves that are nitrided for improved durability and

undercut to improve flow and reduce weight.

• The exhaust valves have sodium-filled stems that promote valve cooling to

reduce wear for better alignment and a consistent seal.

Two-Stage, Variable-Displacement Oil Pump• The variable-flow oiling system helps maximize fuel efficiency with a crankshaft-

driven oil pump that matches the oil supply to the engine load.

• The pump changes its capacity based on the engine’s demand for oil.

Twin-Scroll Turbocharger• An advanced, electronically controlled turbocharger with a unique twin-scroll

design increases power in the ECOTEC 2.0L turbo.

• Each of two scrolls on the turbine is fed by a separate exhaust passage to virtually

eliminate turbo lag at low engine speeds, giving the engine immediate throttle

response associated with a naturally aspirated high-performance engine.

Air-to-Air Intercooler• Air-to-air intercooler draws fresh air through a heat exchanger to reduce the

temperature of compressed air that’s forced through the intake system by the

turbocharger.
