With the Focus ST specifically, the bottom line is you have to address the factory fueling limitations if you want to make around 400whp or more. There is no other way around it. Auxiliary fueling has become the best way to accomplish this and will allow for the mighty 400whp number and any point past that if you're one of the many that just can't have enough power.

The Focus ST is no slouch, that's for sure. It's an awesome performance platform right out of the box with a lot of potential through the aftermarket. Believe it or not, the engine can take a much harder beating than what Ford did with it. From the factory, the 2.0 liter EcoBoost 4 cylinder combined with the BorgWarner K03 "little turbo that could" cranks out 252 horsepower and 270 lb. ft of torque at the flywheel. In our own Focus ST project car, this netted us 237hp at the wheels. Our torque number suggested the Focus ST is grossly underrated because we measured 318 lb. ft. at the wheel. Regardless, it makes some good power at roughly 126hp per liter and even more torque. What about the upper limits of it's strength and durability though?

Nope. It's not a bird. It's not a plane either. It's the tax return sale coming in hot! Starting on March 1st going all the way through April 17th, we're super excited to help you guys save this year!

There is an endless amount of modding that can be done to the Focus ST. From shift knobs to bolt-on turbo kits to performance built engines, the range is limitless. As the saying goes, "to each their own", and that applies here. Whether it's function, form, power, or something else that you care about, there is something for everyone. The good news is you don't have to be rich to modify the ST and you don't need a mechanic's certification either. There are some seriously easy modifications to perform that will change your ST more than you might have thought, all at a very reasonable price tag.

Ever wondered if the hype is real? Here's your answer. Hell yes. Be careful though, if you take the plunge on a big turbo, prepare to never be satisfied with a stock turbo car ever again. It just won't be the same. The experience of a hard wide open throttle pull, holding 22psi, or more, all the way to 7,000 glorious rpm makes you mad that Ford gave you such a puny hair dryer of a turbo now that you know what boost can really feel like.
