Focus Mk3 ST Diesel

A diesel that embarrasses petrol STs. 235, 250 or 280 bhp, and the fuel economy stays.

The Focus ST Diesel has always been a firm favourite in the Pumaspeed office. With the cost of buying one ever more affordable, it's a car that, with a simple remap, has proper hot hatch performance while keeping fantastic fuel economy. What's not to love?

Two development cars, every product tested

Since the Focus ST Diesel's release in 2015 we have owned two development cars: our original white car, taken all the way to stage 3 with 280bhp and 600nm, and our current Stage 2R Tangerine Scream car running a petrol-ST-bashing 250bhp and 520nm.

Owning both has let us test every product on the market and design plenty of our own, which is why we are at the top of the tree when it comes to Focus ST Diesel tuning.

The home of Ford tuning since 1999

Pumaspeed started with the Pumas in 1999. Today the development fleet runs to a Mk4 Focus ST, the Puma ST and the Mk8 Fiesta ST, and we have branched out into the BMW, Toyota and hybrid markets. Our MAXD Out remapping software is unrivalled and the R-Sport hardware we stock is second to none.

So whether you have just picked up your ST Diesel and want a little more punch from the turbo with our Stage 1R remap, or you're after a fully fitted Stage 3 X37 hybrid turbo kit, you know you're in the right place.

Stage 1R  |  235bhp / 490nm  |  From £499.90

Remap, induction hose & engine mount

ST180 Stage 1R Custom Power Package

Where the car should have left the factory. Up to 235bhp and an incredible 490nm. The MAXD Out software is paired with the high-flow induction hose and a lower-vibration engine mount to cope with all your juicy new torque. It is the essential first mod for every Focus ST Diesel, and it can be left as it is or built on for stage 2 or stage 3.

Stage 2R  |  250bhp / 520nm  |  From £1,389

Remap, induction hose, engine mount, intercooler & dummy DPF pipe

ST180 Stage 2R Custom Power Package

The most fun you can have on the stock turbo. More air in, more air out: the R-Sport intercooler and dummy DPF pipe let the standard turbo do everything it can, and the MAXD Out remap turns that into up to 250bhp.

Stage 3R  |  280bhp / 600nm  |  From £2,799

X37 hybrid turbo, remap, induction hose, engine mount, intercooler, dummy DPF pipe, flywheel & gearbox synchros

ST180 Stage 3R Custom Power Package

The ultimate Focus ST Diesel. Need we say any more? Tried, tested and perfected over the years on our development car, with 280bhp and a crazy 600nm. This turbo and the MAXD Out software could not be better.
