The Mk3 Focus ST250: precision over brute force, and 350bhp when you want it.
From a simple power enhancement to a full-blown forged-engine 350bhp cruise missile, the Focus ST250 can be built to your specification. The experts at Pumaspeed can advise the correct path to the perfect ST250.
Big shoes to fill
The Mk3 Focus ST250 had big shoes to fill. Ford had set the bar high with the ST225 and replaced it with something very different: the much-loved five-cylinder was dropped in favour of a far more efficient 2.0 EcoBoost. Here at Pumaspeed we understood straight away that the ST250 was a very different animal from its predecessor, replacing outright power with precision and smoothness.
The 2.0 EcoBoost is no less tuneable, and delivers serious pulling power with only minor modifications. Working closely with MAXD and R-Sport, Pumaspeed have developed a range of tuning options to make your Focus ST250 a true powerhouse. There is something for everyone here, from simple stage 1 maps right up to X-37 hybrid and Garrett turbo options.
