Will Brown's Ford Mustang could get Mostert, Wood engine
The Ford Mustang Will Brown is getting customised will be powered by a V8 Supercars engine, but it might not come from his car.
A new V8 Supercars-powered road car is on the way, with the build of Will Brown’s custom Ford Mustang kicking off, and he is calling for the public to choose what engine should be under the bonnet.
After announcing the project last month, the second episode of Brown’s 1967 Ford Mustang Fastback build revealed the three engine choices available to the 2024 Supercars Champion, with fans getting to pick what will power the pony car.
While giving famed car builder Rob Zahabi of Rides by Kam and his crew a tour of the Triple Eight Race Engineering workshop, Brown said there are three potential engines which could end up in the Mustang, all of which have seen race service in the Supercars Championship.
Two of the engines are ex-Walkinshaw Gen3 Mustang 5.4-litre ‘Coyote’ V8s, both of which were bought by Triple Eight upon its transfer to becoming Ford’s homologation team, coinciding with the ex-WAU team becoming Toyota’s HT.
According to Brown, one engine is that which powered Chaz Mostert and Fabian Coulthard’s #25 in the opening stanza of the 2025 Bathurst 1000 until it expired, leading to an iconic moment where the eventual series champion was offered beers by trackside spectators.
The second Walkinshaw-sourced engine was in Ryan Wood’s Mustang for the final race of the 2025 season in Adelaide, when the Kiwi controversially clashed with Broc Feeney, spinning the latter who was in contention for the title.

A third engine is also being offered to Brown, with one of his current V8s from the 2026 season to become available when it has reached the engine of its racing life.
Brown has detailed the Mustang’s engine will revert to a more production-spec wet sump rather than the expensive and complicated dry sump system used on the Supercars-spec Coyotes.
Fans of Brown have been encouraged to leave comments on his videos and posts about the project to cast their vote on what engine should power the Mustang, as well as have input with later modifications.
