r/FiestaST

Hey there thinking of buying a fiesta st

Well my brother used to have one of these fiesta a orange with orange interior, we really loved that car but hes got family now 2 children and he traded the fiesta for a ford explorer 2022, and i want to be that cool uncle and really like that fiesta, i used to have a mustang but with the fuel price rising i got a ford escape hybrid 45mpg.

But now i really want something with soul and i cant get that fiesta st out of my mind, can you all tell me problems that the fiesta st has? I know that the normal fiesta is a very bad car, but idk about the st.

To join the Fiesta club?

Greetings Fiesta group!

In my usual Facebook browsing, I found this little thing for sale for 5K. 2016 with 100K miles, but Description said it has an issue with the throw out bearing and is undriveable, as well as the obvious paint issues in the pictures provided.

I hit him with a 3000 offer, and he responded with 3200. Has a video of the engine running, so it doesn’t hurt to check it out. I’m mechanically inclined, so have no issue dropping in a new clutch and other needed things.

Currently have a 98 GT, and my Gen 2 MDX as a daily, so this would replace my Acura. I’ve driven a 2016 focus st, and a 2019 golf tdi, I liked both driving and size wise (and the child in me loved the BOV of the focus), so I’m just curious how the fiesta compares?

Honestly, at this price and from what I’ve seen on similar listings, I’d be in maybe 4K altogether granted nothing else major. So I could sell it and at the very least make my money back if I don’t like it, or have a reliable and fun daily?

So, thoughts from owners? How is this is a daily/ just grocery getter, and would this be an easy sell if I ended up not enjoying it like its bigger counterpart?

Amplifying all speakers and adding sub

As the title says, this is my next project on my 2017 FiST.

Got a lc5i pro 5ch LOC and a recoil red1800.5 5ch amp, focal ISFORD series speakers, as well as a rockford 12” sub in a spare tire box.

Any tips on wiring? All the youtube vids ive watched only have cryptic descriptions of how they wired and didnt show what they did, and i’m a visual learner unless it is described in GREAT detail.

I’d like both the sub and the LOC to be under the false floor in the trunk, but am unsure how to begin. I’m assuming running speaker wire from the front/rears in the head to the trunk and then back to the front so i can reuse the factory wires to the doors is the easiest, as the focals are plug and play, not wired in. i’ve wired in amps before but that was with older cars using aftermarket single DIN stereos.

How do i power the LOC? where do i wire the remote turn on to? Should i use the LOC bass knob or the amplifier bass knob?

Pulling the seats is a non issue if i have to for a clean install but would also like tips on wire routing. Any help is appreciated and pictures would be fantastic if you have a similar installed setup to what i’m trying to do

Help! Coolant leaking, can’t find source.

Howdy! Our ‘15 has been leaking coolant but I cant find the source. I’ve highlighted the area where I see pooling.

Before I start removing the intake and battery harness, has anyone dealt with this? Or know what part is located in the highlighted area?

Thank you!

Hot side pipe needed for mapping?

Hi guys, planning to do a custom map for the car. So far I got an airtec stg1 intercooler, itg intake, colder plugs, new coils and a rear motor mount. Are hot and cold charge pipes weak and is it needed? Any answer is helpful, thanks!

Those who have done your own timing belt.

How involved was it? I have no problem turning wrenches, doing shit by the book. I've already done control arms, engine mounts, rear bushings and spring seats. I've always worked on my own cars but I've never done a timing job and this motor in particular seems a bit tricky. Any tips going in? I will be buying the full lockout toolset and doing the job properly. I've heard of people bending the locking tools though and throwing off timing.

17x8 Rims

Hey lads,

I’ve recently bought some 17x8 Rotiforms for my 2013 fiesta. It’s currently lowered on white line lowering springs. Any recommendations on tyres size or any info on if i’ll have to roll my guards to make them fit would be appreciated.

Odd Whining Noise

I'm getting a whining noise from my Fiesta ST that I got a few weeks ago. I thought maybe it was the infamous transmission whine, but it does it in all gears, in neutral, clutch up, clutch down, standing still, etc. it makes it from about 2k-3k rpm.

Sounds pretty similar to a sustained pigeon cooing, or like blowing across the top of a glass bottle.

Lithium Battery Replacement Issues?

Planning on replacing my front battery with a Titan8 PWR S5-3400 in the trunk. I tried looking up some posts but didn’t come across much other than track focused builds. Has anyone tried running off solely a lithium battery, and if so, did you run into any issues or difficulties especially with the factory BMS? any input would be appreciated

Fumes smell in cabin

Bit of a random one, this has been going on for about a year and a half ish.
Its fairly intermittent but that could be on and off each day for a week to be on for a month and off for 4 days before its back.
My dad thought it couldve been from oil burning (which it does burn oil in fairness) but its sometimes strong on startup after maybe 3-4 days without turning it on although he is much more of a mechanic than me.
Im starting to get annoyed at the car tbh with random maintenance things coming up but this is what bothers me the most as I cant figure it out. Not seen anyone else have this specific issue so thought id have a punt here for any help.
Engine runs reasonable well and the pcv was changed if that means anything when that packed in about a year ago (around the time that the fumes started but feel like it was before so likely unrelated imo)

Any help would be greatly appreciated, Cheers.

Looking into getting this fiesta st

Mileage is 110k as of now, mods list is listed below, one accident it was a side swipe but clean title. Talked the dude down to 8,770$ would this be worth it only thing unknown is how many miles on bigger turbo and clutch. Should I purchase or stay away any opinions would be amazing! It’s a 2 1/2 hour drive from me. And anything to look out for?

Is this how the top of my window trim is supposed to look? I feel like I’m missing a part here. If it is, anyone know what it’s called?

Broken terminal clamp

Hi folks,

Battery nearing the end of life, planned to change it today. When I got to unhook the old one, it's full of corrosion (I had noticed some a while back but didnt realize the extent of how much it had worsen, that's on me).

The corrosion/rust has eaten up the clamp and whatever small connector attached to it (there is a bit of broken copper in the connector, see the elegant finger pointing 👉)

Any advice as to how to deal with this? Would you know the parts #, and whether a swap would be just some bolts + crimping of wire, or would require more labor?

Picture of the sadness enclosed, appreciate the help!
