Ford Australia’s Barra is possibly the greatest motor produced in Australia, and I feel it should come to Forza, as a swap option for the Falcons (and possibly the Holdens/HSVs), as well as other Ford vehicles, other large sedans/muscle cars, and up to anything that currently gets the similar 2JZ swap.
The Barra is a family of 3984cc Fuel Injected DOHC Inline 6 engines, with came from the factory either naturally-aspirated or fitted with a single turbo. The NA factory builds are the Barra 182, Barra 190, and Barra 195, the numbers referencing output in kilowatts, and the turbocharged builds are the Barra 240T, Barra 245T, Barra 270T, Barra 310T, and the Barra 325T, just to give you an idea of the factory/street build power ranges.
In the aftermarket space, they’re an alternative to the 2JZ, and people are getting to 220kw and above with naturally aspirated builds, and turbo builds can get north of 1000kw. This does put it into a similar box as the 2JZ, but Barra builds will have more torque down to the larger engine size. They’re also a good alternative to a V8, as they produce similar power but reduce weight over the front end, which aids handling. Crucially, they also give us some Australian automotive representation, and I think more people should have the opportunity to experience Australia’s best engine.
