The Rise of the Ford Barra: An Australian Legend
20200924 213047 1024x1024
When it comes to Australian automotive history, few engines have left as indelible a mark as the Ford Barra engine. This engineering marvel emerged from the fierce rivalry between Ford Australia and Holden, a competition that dominated racetracks and sales counters alike. The Barra’s story is one of ingenuity, resilience, and power, cementing its status as an Australian automotive legend.
The War Between Ford and Holden
The rivalry between Ford Australia and Holden in the late 20th and early 21st centuries mirrored iconic battles like Carroll Shelby versus Enzo Ferrari. Holden’s Commodore, armed with the revolutionary LS engine, had begun to dominate both racetracks and sales. This forced Ford Australia to rethink its strategy, ultimately leading to the creation of an engine that would redefine the performance car market: the Ford Barra engine.
The Genesis of the Barra
Faced with Holden’s success, Ford needed something extraordinary. Holden had already introduced the LS1 V8 to the Commodore, refined by HSV (Holden Special Vehicles) to create a 400-horsepower powerhouse. Ford’s lineup, in contrast, relied on ageing inline-sixes and V8s that couldn’t match Holden’s innovation.
Gordon Barfield, Ford Australia’s Special Vehicle Operations Manager, proposed turbocharging their reliable 4.0L inline-six. This idea became Project Barra, named after the barramundi fish, symbolising its Australian roots and tenacity. After $500 million in development and over 24,000 hours of testing, the Barra engine was born in 2002. It combined durability with exceptional tunability, becoming a symbol of Australian automotive pride.
Barra vs. The World: A Design That Dominated
The Ford Barra engine stood tall against global competitors like the Nissan RB and Toyota JZ inline-sixes. Its robust iron block featured extensive ribbing and reinforcement, essential for withstanding the immense pressures of high-performance tuning. The closed-deck design provided additional rigidity, preventing cylinder bore deflection under extreme loads.
Key highlights of the Barra engine included:
- Twin Variable Cam Timing: Inspired by BMW, this system optimised exhaust flow at low RPMs, improving turbo spool and efficiency.
- Garrett GT3540 Turbocharger: This oversized turbo was capable of delivering 600 horsepower worth of airflow, even in stock form.
- Perfect Balance: Inline-six engines, including the Barra, are inherently balanced, ensuring smooth operation and durability.
The Barra’s initial output of 322 horsepower matched the LS1-powered Commodore of the era. Yet, it was its untapped potential that captivated enthusiasts. With modest modifications, the Barra engine could handle up to 2,000 horsepower—a testament to its exceptional engineering.
A Tuner’s Dream: Unlimited Potential
The Barra engine became a favourite among tuners for its versatility and affordability. With variants like the naturally aspirated Silver Top, turbocharged Red Top, and dedicated LPG-powered Green Top, the Barra offered a wide range of configurations. The robust iron block and crankshaft were shared across models, making them ideal for high-performance builds.
Popular tuning setups included:
- Using Green Top taxi engines as a base for high-power builds, leveraging their stronger connecting rods.
- Adding a turbocharger, upgraded valve springs, and head studs to achieve over 700 horsepower.
- Running E85 fuel and larger turbos to extract even more performance.
This adaptability made the Ford Barra engine a cost-effective alternative to imports like the 2JZ and RB engines, often delivering similar or better results for a fraction of the price.
The Falcon and Beyond: Barra in Action
Ford Australia utilised the Barra engine in the Falcon XR6 Turbo, a car that quickly became a favourite among enthusiasts and law enforcement alike. Police agencies across Australia and New Zealand appreciated the XR6 Turbo’s speed, comfort, and reliability. It became a staple in patrol fleets, capable of matching or outpacing vehicles used by offenders.
Efforts to bring the Falcon and Barra engine to the United States were made in 2005 and 2009, but Ford executives ultimately blocked the proposals. Instead, Holden seized the opportunity, exporting the Caprice as a police patrol vehicle in the U.S., leaving the Barra as a uniquely Australian treasure.
The End of an Era
Despite its success, the Falcon and its beloved Barra engine met their end in 2016 when Ford Australia ceased local manufacturing after 56 years. The Barra’s legacy, however, continues to thrive in the tuning and motorsport communities, where it remains a symbol of Australian ingenuity.
The Barra: Australia’s Homegrown Hero
The Ford Barra engine represents the pinnacle of Australian automotive engineering. Its combination of reliability, power, and tunability rivals some of the greatest engines from Japan, Germany, and America. While the Barra may never have graced American roads, its impact on Australian motoring culture is undeniable. For enthusiasts around the world, the Barra is not just an engine—it’s a legend.
