The engine is based internally upon the Barra 270T, with extras added from the Barra 310T variant such as the turbo, intercooler and injectors. In an Australian first, Ford also employed a custom designed carbon fibre air intake which increased airflow by 45 percent. It was chosen to base the engine on the 270T instead of the 310T due to the increased compression ratio.
The decision to base the engine on the Barra 270T was influenced by its higher compression ratio, which led to the incorporation of additional components from the Barra 310T variant, such as a turbocharger and intercooler.
