Forged connecting rods, a forged crankshaft,
improved cylinder head and
block water pathways, and sodium - filled exhaust valves give the 2.0 - liter additional durability and power capability.
The
cylinder block was thicker for
improved strength, the turbo upgraded to a Garrett T04, a larger intercooler and better oil cooling system and revised induction and injection setups, for a maximum output of 222bhp.
The
cylinder block was covered by a 16 - valve SOHC head, but with modified intake ports and
improved combustion chambers.
Turbochargers are packaged adjacent to the
cylinder block and have
improved mounting providing NVH (noise, vibration, harshness) improvements.
Better engine crankcase breathing and efficiency.: Significant development work and computer - aided engineering optimized the
cylinder block for more efficient airflow in the crankcase as the pistons move up and down in the bores, resulting in
improved torque at higher engine speeds.
Cylinder block head was also
improved.

improved.
By shortening the bore pitch compared to the present engine models and reducing the thickness of the
cylinder block and camshaft, engine weight is reduced by 15 % and fuel efficiency is
improved by 10 %.
The engine has an aluminum
block and steel pistons, as well as further -
improved Nanoslide coating of the
cylinder walls.
To that end, a
cylinder block rapid warm - up system suppresses the flow of coolant into the
block when the engine is cold, and a piston cooling oil jet control system cuts the supply of oil to the pistons to
improve warm - up speeds.
