I'd like to dedicate this thread to discuss all things performance for Fiesta ST.

Do you guys think it could have a +250hp potential?

Highest horsepower potential with the Borg Warner KP39 turbo?

Here's are the basic upgrades I plan to do to my Fiesta ST.

1) Tune
2) Intake
3) Exhaust
4) Intercooler

Other upgrades:
1) Coilovers
2) Wheels

I think I'm just going to do a tune, exhaust, and CAI. That won't be for awhile, though. Maybe just a tune and a drop-in K&N filter. Those would probably be my first 2 upgrades. Anyone know how the fuel pump's holding up? One of the biggest problems with my MazdaSpeed 3 was that the fuel pump was pretty much maxed out, in it's stock configuration.

I remember getting a tune on my 2004 Focus SVT. The tune made it feel like a completely different car. Seemed there was a lot of potential blocked in that car, from the stock tune.

What I have read so far is that the tune and a different airbox help the most so far then the next step would be to add a bigger/better FMIC to cool the intake charge. have not heard or much in the way of exhaust So I maybe thinking that mod will be for better sounds and less weight unless I go with a HiFlo cat or go catless since here in the land cows and cheese they don't require a yearly test to get a car plate renewed (yet) But I never really like the stink a catless car has My old Acura RSX was like that and it was very hydrocarbon smelling... As for my first mod even before a tune will be light wheels and sticky tires I like the stock ones but a 22.5 lbs a wheel I can do better an the tires are ok but they are not Dunlap DZll or BFG Rivals. Anything within reason to get the 130+ lbs we took on to get this 5 door sweety rear seats Gone on track days spare tire Ill go like my 2011 GT with Brembos air pump and a can of green slime fix a flat... I think we get roadside assistance don't we ?? maybe find a doughnut spare that will clear the rear brakes and do a dble swap if the front is flat and the rear is good spare on rear and full size on front it would work in a pinch.. fun fun fun thinking out load while a wait for my car to be built and shipped this next week or so.... this is the silly season. looking forward to SEMA and what that brings for ST toys :)
Oh one final thought on a tune .. it make the car so much more fun to drive I had a tune on my Mustang like woke it up to the point it was like this is how it should have came from Flat Rock with the drive by wire car they dog up the tip in of the throttle so when you step on the gas it is a second or so before the throttle plate moves with this tuned you have quicker response and better drivability and lots mot fun cuz when you nail it its there ... Also love the Torque this car has at launch speed my other car a FRS had nothing till 4500 rpm great after that but typical Japanese car all go up hi and little grunt down low. anyway I am really stoked about tuning this car to see if we can get 250 rwp.. and if the clutch can take it lol can you say smokey burn outs ?? LOL naw they can build 2 step launch control into the tune i bet or at least hope so.... im babbering now so I bid you good night :)

When it comes to the world of performance tuning, there's only so many options. Whenever a ripple is made in the small pond we call the automotive performance world, it sends a shock wave through the marketplace. All it takes is a new vehicle that is built within certain parameters and walla; a new automotive enthusiast market is born.

Thanks to Ford, the ripple has been made with the 2014 Ford Fiesta ST, a 1.6 liter inline four cylinder turbocharged engine nestled into a beautifully crafted four door hatchback. This is the perfect platform candidate to fall in line with the tuning legends of hatchback lore that we've all grown to love.

Consider the previous iconic hatchbacks and what they offered to our world. Thankfully, praise be to the Ford gods, the new "EcoBoost" engine lineup for the entire Ford family of vehicles is based on turbocharged principles and that technology has found its way into a 2,700 pound front wheel drive fun-buggy. More specifically, the EcoBoost lineup comes with a slightly higher compression ratio than the conventional turbocharged setup, thus yielding daily driven efficiency in combination with turbocharged performance; but more importantly more power and more fun than ever before.

2014 Fiesta ST specifications:
•1.6 liter Ford EcoBoost inline four cylinder engine
•1596 cc of displacement (97 cu. in.)
•197 hp @ 6500 RPM / 214 tq @ 3500 RPM
•6-speed manual transmission
•Flashable CAN-BUS ECU (Tactrix & Cobb compliant!)
•21 PSI / 1.44 bar
•Borg Warner KP39 turbocharger
•10.0:1 compression ratio
•Twin independent Variable Camshaft Timing
•Direct Gasoline Injected
•All aluminum block / head
•2720 lb. curb weight (estimated)

Enthusiast Oriented Details

While there isn't any details available on what the internal components are made of such as pistons, rings, etc.; it is safe to assume that this is an OEM internally forged or strengthened motor. In order to run 21 pounds of boost from that small of a turbocharger, we all know that heat is increasing the chances of detonation. The Fiesta ST even comes with a unique boost controller that switches between max and min settings of 21/14.5 psi set on 20 second, wide-open throttle increments. This tells us that it is safe to assume that the motor is well-built internally, and could accept larger power output numbers; but the stock turbo's efficiency for horsepower output just isn't there so Ford uses the ECU to limit high pressure, high heat output.

Unfortunately, we never get a "perfect" tuning enthusiast vehicle straight from the manufacturer. There are always compromises, and the Fiesta ST's only fault is an all-aluminum block, which could lead to stumbling points on performance builds. Unlike certain JDM brethren, the 2014 Fiesta ST comes with an aluminum block to help save weight and improve fuel economy. Aluminum blocks make it very difficult to run high amounts of boost and tend to crack around the cylinder wall / coolant jacket adjoining radii. Relax, there is a remedy for this and it is called "block sleeves". Sleeve your cylinders and you should be good to run 30-45 psi depending on your build. That being said, in my opinion you should still be able to double power output on the stock block with a larger turbo at same or slightly higher pressure and be just fine.

Build Examples

There's basically two levels of performance in the enthusiast world; daily driven, and full-race. Whichever side of the fence you fall on, the Fiesta ST should be able to accommodate. For those who just enjoy a simple bolt on and tune, the Fiesta ST should have no problem cresting a conservative 250 whp with simple upgrades such as an exhaust, larger fuel system, intake, intercooler, and a tune. At this power level, the Fiesta ST should remain totally dependable and still achieve 25+ mpg.

Noteworthy details!
•The BOV or bypass valve is built into the turbo compressor housing. In order to run an external or aftermarket valve, you'll need to plug the compressor housing and run a custom pipe on the chargepipes. You can't just buy the turbo, you'll need the plug for the compressor housing plumb work too.
•The Fiesta ST engine control unit, or ECU is totally tunable and is CAN-BUS compliant just like the Focus ST. There isn't anything on the market yet for the Fiesta, but rest assured that interested aftermarket parties are hot on the trail of allowing you to flash this ECU just as they allowed you to flash the Focus ST ECU. I haven't had access to the Fiesta ST yet, but I imagine that the Tactrix 2.0 cable and ECUFlash / RomRaider with the right definition XML files should open the ECU without problem. There are also handheld tuning computers connecting through the OBD port in older European models, so it is safe to assume the same can be said for USDM vehicles as well.

On the opposite side of the spectrum, let's say that you want to go all out and have the baddest Fiesta ST in all of the land. You're going to be able to accomplish all of that and more. The car weighs next to nothing, and with a full build, some street/strip tires, and a little bit of weight reduction; your Fiesta ST will be a highway monster! I see no problem hitting 600-800 horsepower out of the Fiesta ST once fully built. Please understand that 600-800 whp is going to require that you do every engine building trick in the book and is not for the novice enthusiast.

Summary

Overall, the Fiesta ST appears to be quite the impressive beast. Based on tuning principles covered above combined with an initial offer sticker price of mid twenties brand new, given five years of market saturation it is totally reasonable to believe the Fiesta ST will be in the $10k tuner market no later than 2018. For those of you wanting in on the action now, go talk to your local Ford dealer about ordering one in advance. Don't be surprised if you see a line!

PS - A little bird told me that aftermarket companies are totally randy over the new Fiesta ST and that they all have big plans for it. This is a car to keep an eye on!

Well said, and yes SEMA is the place to see what comes out for the ST.

Not 250hp but pretty damn close and for this type of engine and setup I would be totally satisfied If my FiST had this output...


Today's Fiesta ST tuning project comes from Loder1899, a German company that specializes in Aston Martin, Land Rover, Jaguar and Ford. They took the Fiesta and breathed new life into it, especially under the bonnet. Through the usual mix of ECU, filter and exhaust, the 1.6-liter EcoBoost has increased its output from 182 PS and 240 Nm (177 lb-ft) of torque to 235 HP (173 kW) and 335 Nm (247 lb-ft) of torque.

I would be happy with that amount of power.
