I'm new to this forum and to the fiesta. I don't currently own one but I intend to and I'm doing my research ahead of time, I'm considering a 2014 fiesta st. I'm having difficulty googling results that I'm looking for.

Performance wise, is there enough upgrades without rebuilding the engine or upgrading the turbo that would allow me to get around 250 hp? I know there are cold air intakes, FMICs, and cat back exhaust systems, but finding the increase in horsepower is not as easy as I would have thought. Sound is a concern to me but the power and torque are more important to me. I haven't seen any exhaust manifold or headers that are aftermarket. Any suggestions for better cold air intakes, FMICs, and exhaust systems that would maximize performance?

Also would I have to get a new engine to handle a more powerful turbo?

coming from a 2011 Fiesta, the ST is probably one of the easiest cars to find performance parts for. It is crazy how much stuff there is for the ST and how great the increases in performance are with each part.

Is there a reason why you are targeting 250hp?

You can easily get 250 out of the FiST if you're willing to spend the money to import the parts you need.

240bhp: http://pumaspeed.co.uk/product-Ford-Fiesta-ST180-240-bhp-Power-Upgrade_16275.jsp
260bhp: http://pumaspeed.co.uk/product-Ford-Fiesta-ST180-260-bhp-Power-Upgrade_16515.jsp
270bhp: http://pumaspeed.co.uk/product-Ford-Fiesta-ST180-270-bhp-Power-Upgrade_16584.jsp

I don't recall if the Euro FiST has a different ECU/sensor set up than the USDM one but if so you can probably buy the parts without a tuner from Pumaspeed and get an access port and custom tune to match the parts.

The higher spec kits are using their modified stock turbo. The small turbo, even when optimized is still small. Nevertheless, I'm sure with current bolt ons as soon as a slightly larger turbo comes out achieving the extra 20hp needed at the wheels to hit 250 would be very, very easy.

US spec uses a differnt ecu. Ive seen cars with upgraded fmic intakes and tbe with cutom tunes and seen none over 230 whp. The turbo is pretty much maxed from stock. Bhp and whp are not the same. 270 bhp is around 230whp. Even with an updated stock turbo 230 whp is not much for some. Atp has 3 turbo upgrades available. Smalles turbo available can reach around 265whp

Thanks for the replies, very helpful. 250whp. I just thought 250 would be easier without huge upgrades. Although after looking at that PumaSpeed site maybe Ill go for 270bhp. I heard somewhere that the Engine can handle up to 250hp....maybe I misunderstood, Maybe it was the stock turbo with the stock engine.

The ATP turbos actualy are still not big at all. Their biggest turbo the GTX, is actualy not maxed out at 310whp, it still has some power left in it. That is with supporting mods, but no engine work.

The chart above is very general in nature, too many variables to go by it directly, you have to look at the compressor maps, dyno charts, etc....

I was really excited about the ATP turbo and was going to get one until I read the dyno plot, the GTX has no bottom end so what you have really done is robbed the bottom end to feed the top end and where to you do most of your driving, on the bottom end....not really a good solution for a daily driver, etc.....only for when going all out. What about the GT25, still give up bottom end and from somebody that really knows this stuff, worse than it seems and it runs out of steam on the top end so you are pushing it hard just like the stock turbo on the hotter tunes being done to it now, ultimately it may fail.
What to do, I wish they had an offering that could make a nice wide power band so we have power available all the time and more top end, anybody in for a sequential turbo setup??? Lots of added weight and complexity there, same with an SC/Turbo twin boost setup.

The only real choice I can see and still not perfect but much better is the BW EFR 62/58 at least for my needs and on a well ported manifold, it needs and adapter to mount it, etc....but there is a manifold in the works for a direct bolt on, I hope to have one here soon to test out.

Cool thing is that it will not be a huge task to install, it is a BW afterall, not a bolt on, DP will need to be made or as in my case modify the DIY one I have. Intake, etc, not much to that, water and oil lines easy to hook up, sensors, controllers, etc, pretty much plug and play.

I have talked to ATP, to BW, to tuners with great experience, studied all I could find, I am going this route.

If you want 250 max and not try to make more later, you might be OK with the GT25 but the EFR will be better and not much difference in the end cost.

I really like ATP, great company, I just wish they had a better turbo for us, if they had something like the EFR and ready to bolt on I would buy it, now.

you've done your research ramaudio. the 250hp goal was more of me just trying to be realistic. if I can get more hp and torque fairly easily, I'll do it. I definitely don't want to lose much at the lower end so I may go with the gt25 or the efr and an exhaust system to compliment it, along with air intake and fmic. If money was no issue at all i might just drop a mountune rally cross engine in :)

Be patient, the EFR is being sorted out in the not to distant future, it will be the one you want, it is the best option we have for those that want good power and the best power band we can get. Those that want big power either know that they are doing and OK with no bottom end or are excited by big numbers but may of never had to live with all that it involves on a 1.6L engine.

I had the first 1ZZ turbo Matrix back in 2002, 250WHP, about the same weight, really good torque out of the 1.8, still got 35MPG on the highway cruising and it was quick, daily driving, mountain runs, autocross, decent at drags, very reliable.

In the NA world, a huge number of parts only rob the bottom end to add to the top end and end up being slower when needed the most if you use your car for a daily driver. In boosted cars it is a bit the same if you go with to big a turbo but can be a significantly bigger end result.

Example, going through an intersection, big ass truck about to Tbone you, punch it, gone and safe, big turbo, could be dead meat.

That is a bit extreme it may seem, I have lived through some scary times and glad I had power when my life depended on it.
