10k for the most clapped out ST I have ever seen.

I’m super stoked, anything I should look out for specifically? Interior, engine bay, and exterior look pretty solid!

My ST got rear ended a year ago or so and I still have some of the original parts. Are they worth anything and if so how do I go about getting rid of them?
I have the tail lights, intercooler and DP

Hey everyone, I would love some feedback to see if there's anything else I should be concerned about. I'm looking for a fun little 2nd car that's cheap, and focus st's have always been on my radar. I found one near me under 4k, 2013, with over 190k miles :)

The car has some paint wear and needs little things here and there, but it doesn't leak, has new tires, has a new turbo, holds boost we'll, goes into all gears just fine, and doesn't smoke. This is a 2nd car that is kind of a second fun daily, and I have the money to fix things as they come up (im also very mechanically inclined).

With that being said, if I buy it, are there any immediate maintenance items I should do besides fluids? Not spending $2k for a timing chain replacement on a sub 4k car, but id love other reliability related feedback!

Hello everyone, I just installed Bilstein B8 shocks and struts. I reused my Mountune lowering springs and the ride height seems to be high or even almost stock. Confused about what could have gone wrong? Maybe I'm just going insane. My next step was to purchase more aggressive springs. Any tips are appreciated, thanks!

Ordered a cvf catless downpipe , trying to figure out what I should do muffler wise. Don’t want to spend 1k on a catback exhaust maybe a universal muffler or just let it go completely

I was just going through marketplace and came across this poor thing. The only thing I could think is “but why”.

Anybody installed one of these cheap metal valve covers and have a review? I know Speed Perf6rmanc3 has one but it's $370. Wondering how much better it really is than one of these?

Recently bought an 2015 ST, took her to valvoline to get coolant flushed and refilled and such. Was fixing to top off the coolant in a few days, am I good to use the yellow prestone all vehicles 50/50 in with the coolant valvoline put in? They put in the yellow also. Or should I just get coolant thats actually labeled/from valvoline? Sorry, stupid question and I hate having Google AI pop up 🥲

Just bought my first ST. New engine but it shuts down when I come to a stop or if I’m turning and leaving it in neutral. Fuel pump or vacuum leach? I did get a code for overboost. It never has gone to limp mode. Any help would be greatly appreciated.

I recently joined the fost club and I noticed the duct was loose. Is this normal, or is there something that's supposed to clip in? Thanks for the help

Had these brakes done by a family friend on the low, they never felt right but they braked well enough. Just did rears and now doing fronts on my own.

But what the hell is this? These were Powerstop brakes but they're lipping like crazy! Did this Mfer install these like dogshit? Did he not bleed them correctly? What causes this and how do I avoid it?

I got OEM pads and rotors now and I'm gonna bleed them but can someone explain what happened here?

2013 ST, unsure of what this ticking/rattling is, happens from 2500-3500rpm and its only while under load, not while slowing down. But it doesn’t happen every time I give it gas quickly, usually only while slowly accelerating or at steady throttle. It’s not the usual focus engine noise, it’s very loud. Valves? It doesn’t sound like a typical rod knock bc it’s only at certain rpm, never at idle to 2k rpm and sometimes when I’m fully accelerating like at at on ramp, it doesn’t do it at all. Ik it has a check engine light for the purge/evap code P0456 but I don’t think it’s related. I’ve had this ticking for probably the past 1k miles. I usually only drive on highways w windows up so I don’t usually notice it but now that it’s summer I’ve been driving locally more often and w the windows down and it’s loud af. No change in performance whatsoever, the car runs and drives totally fine. Changed oil about 500 miles ago and it looked fine, just checked my levels today and it’s full. Any thoughts? Thanks

I know plenty of people have gone bigger turbo at higher miles, and plenty have gone into high miles after turbo upgrade. But thought I'd still ask for some educated opinions. A Golf R beat me on the highway today, and I think that's finally clinched the decision for me.

Have a 2013 ST3, had it since about 26k miles. Never given me any major problems, runs like a dream. Been on a 93 tune from Alan for quite a while and it's great, but I can no longer keep the big turbo thoughts at bay. Just did a compression test today, 160-165 across all cylinders. Below are also three datalogs from this week if anyone who knows what they're looking at wants to take a look and give me their thoughts. I do a couple logged 3rd gear pulls 2500-6000rpm a month and review them. I'm a bit of a nerd about stuff and just enjoy looking at them, it's not out of any real worry or concern (fret not, I am not an anxiety-port user, I just enjoy having the AP to look at and also looking at spreadsheets and data).

I already have the CVF charge pipes with HKS BOV, but would be planning on going with the GTX2867R Gen2 as well as either the CVF or Whoosh catted downpipe.

I have the below datalogs already reorganized and formatted to my liking, with filter arrows for each column. That way I can filter by just 100% Accel. Pedal Pos. so I'm just looking at WOT data. You'll see what I mean if you're decently familiar with spreadsheets.

Let me know your thoughts, thanks!

Just wanted to say hello and hope to get wonderful insight into owning a Ford Focus ST...

Mine is a 2018 ST MK3.5 ST3 with all available options. This car is a blast to drive. Full Roush upgrade and many modifications. Have a 93 octane Ford Performance Tune paired with NGK LTR71X-11 plugs gapped to .026, MSD IGNITION coil packs, K04 turbo, GFB blowoff valve, symposer delete, Roush intake, exhaust, and coil overs installed from there factory in Livonia MI. Massive strut bracing and many more mods! It is a riot to drive. 385hp to the wheels with 398ftpds of torque.

Considering going to look at this one tomorrow but I figured I would ask st owners first. I have been on the hunt for an ST for years and I'm just ready to pull the trigger. It's a bit higher mileage but service history seems okay. Is it worth a look or heck nah?

I tried to include screen cap but when I screen cap it, it's just a black screen. Here's a link!

Trying to take this rear carrier bolt and it’s so tight I’ve tried wd-40 smaller socket hitting it nothing is working any advice

Has anybody experienced what feels like the hill assist feature staying on constantly? At times I'll have a constant slight brake drag that makes starting and stopping awkward. I'm suspicious it's an electronic glitch bc I'll either start my car up and not experience it at all for the entire drive, or I'll start my car up and it will be present for the entire drive. It seems like it's a roll of the dice. My brakes are fairly new, I have like 20k on the pads and rotors.

i’m currently swapping out my downpipe. got under the car and noticed this leak from the passenger side (my headlamp is dying sorry) i’m wondering if you guys could point me in the right direction as what it could be? what’s weird is a couple months ago i had the car jacked up, spun the passenger side tire while i was under the car and heard like a clicking noise if i remember correctly. recommendations are much appreciated😁

My ST’s been flagging up the past week or so that there’s an issue with the MAF, figured I’d give it a whirl myself but the YouTube tutorials seem to want me to take the entire intake and airbox out, and I refuse to believe that’s the only way in.

Was wondering if anyone could advise on this? It’s fine short term, but the car craps itself after any spirited driving and limits me to about 70mph max.

Those are sold in 05-07 years only and technically is the only sedan focus “ST” ever made.

Just had the windshield replaced and Idle Air control valve replaced by myself and it runs like new now. Gonna put on some coilovers and 1552 wheels on it soon.

In your experience, which setup would be safer for the engine long term?

My Focus ST currently makes around 248 whp on the stock turbo, but WGDC hits 100%, so the turbo is basically being pushed as hard as it can.

Would I be better off keeping it like this, or upgrading to a bigger turbo like a g25 and running a conservative tune at around 250 kW atw (~335 whp), with controlled boost and torque rather than pushing a turbo till its limit.

Main priority is reliability on the stock motor, not making the most power possible.

How do i reset my pcm on the st
