Motorbase Performance will use 2.0-litre Ecoboost engines in the Ford Focus STs it will enter in this year's Dunlop MSA British Touring Car Championship.
The competition unit is derived from the 247bhp four-cylinder engine from the Focus ST road car and replaces the Duratec unit used in last-year's race-winning Focus.
Tuning specialist Mountune was charged with making adaptations to the Ecoboost engine to ensure it meets the BTCC's Next-Generation Touring Car (NGTC) specifications. Official power figures aren't forthcoming, but it's common for BTCC engines to produce in the region of 320bhp.
Motorbase's technical partners Samco Sport, Pro Alloy and Specialty Fasteners all provided assistance throughout the process.
The build and preliminary testing of the first engine has been completed. Next, Motorbase will test the unit ahead of the opening round of the season at Brands Hatch circuit on 4/5 April.
“It’s been a busy winter for us behind the scenes, but I’m delighted to be in a position to finally go public with this very exciting development for Motorbase," said team boss David Bartrum.
"The Ford Ecoboost engine has been a long time in the planning and it’s only really come together in recent months thanks to the great teamwork and input from Mountune and our technical partners."
David Mountain, technical director of Mountune, said: “There's still more development to do before the start of the season. Having said that, we're confident that by the first round we'll have a strong package available, from which we can build during the course of the season.”
