Ford Barra engine

[citation needed] This engine is found in the 6-cylinder variants of the BA Falcon (also derivative models Fairmont and Fairlane), and SX Territory, and was produced between late 2002 and mid 2005.

Changes from its predecessor include an increase in compression ratio, a slight revision of the cam profiles, a revision of the air intake system, the introduction of dual independent variable camshaft timing, a secondary knock sensor and an upgraded ECU, which allowed for more sophisticated ignition timing and spark control.

It is similar to the naturally aspirated Barra 182, except it has different pistons to lower the compression ratio, a single Garrett GT3582R turbocharger, higher base fuel pressure, Inconel exhaust valves, red rocker cover, and an intercooler.

Aesthetically the engine is the same as the previous model, with the exception of the Territory Turbo using a black rocker cover and a top mounted intercooler.

The increase in power is achieved through the use of higher boost pressures from the otherwise under-utilised large Garrett GT3540 turbocharger, a larger intercooler, revised air intake.

With the introduction of the BF Falcon in 2005, the 270T also inherited the upgrades found in the 245T, but the power figures were left unchanged.

The result is that the FG XR6 Turbo is faster than the FPV's BF Typhoon although they share the same power output.

Featuring a larger turbocharger and intercooler, different pistons to reduce compression, and larger injectors than its less powerful sibling (the FG Barra 270T), it was the first engine manufactured in Australia to produce more than 100 hp (75 kW) per litre, producing 310 kW at the flywheel.

In an Australian first, Ford also employed a custom designed carbon fibre air intake which increased airflow by 45 percent.

It features a liquid phase injection autogas system, allowing for much higher power and torque than previously.

Ford Australia president Bob Graziano cited unprofitability due to high labour costs and dwindling market share for the demise of local manufacturing.

With time, the turbocharged I6 engine found strong favour with enthusiasts, due to its ease of tuning for more power[14] and the cheaper yearly registration fees associated with fewer cylinders in some Australian states such as Queensland.

It also had more aggressive ignition calibration, slight increase in compression ratio, and various ECU modifications to comply with Euro III emissions standards.
