Great news! Glad you have a warranty!!
you’re correct all ecoboost mustsng 2.3 engines are the same the only thing is they ford/other companies made a new improved head gasket, for my built block I’m running a ford focus rs MLS head gasket sold by EMS and the ford focus rs has a 2.3 ecoboost engine from the mustang they use a different turbo and the engine is mounted side ways and awd but the engines are all the same the problem is the short block is weak for the power it makes so it cracks or exploded in my case lolll and usually the head gasket went out but I never had a head gasket issue that’s why the ford focus st has a 2.0 block which is stronger than the 2.3 short block ford made buttt the 2.3 makes more power that’s why you can put a 2.0 st block with a 2.3 cylinder head and make hella power but as the issue for OP check ur coolant do an oil change if it’s chocolate milk yea …. Also check to see if ur losing coolant or how much oil burned
You are correct that the Focus ST has a stronger block since it is a semi closed deck block versus the open deck block in the mustang. The difference between the 2.0L and 2.3L is the stroke since they are the same bore size and why builders use the 2.0L ST block to build HIPO 2.3L motors. The aftermarket will always fill the gaps that the new car manufactures leave open due to time and money constraints imposed by the bean counters.
defintely. I don’t want the same thing happening down the road with no warranty. The shop I’m bringing it to is a great shop but I guess we will see. Thanks for the info!
LOL, so the easy solution to saving your engine is to run 87, with its inherent reduction in power!
Here's a YouTube video from a guy who was able to take the time and explore the cause of Ecoboost head gasket failure.
No... I don't think so!?? I even run 89 octane or E15 in my Ford Fusion 2.0 Ecoboost Titanium.
No, running 87 octane fuel will help bring about an early demise of your engine since it will be much more prone to suffer from detonation and LSPI. At least 91+ only.
The best solution is upgrade your fuel pressure sensor Parker performance sells the maintenance kit spark plugs, Fuel pressure sensor , and the boost reference line that’s connected to the bov and last but most important lol KEEP THE CAR STOCK lolll it’ll be a good daily but once you push more than 20psi that’s stock max boost you’re taking that risk race car lollll
Yep 20 psi is stock Max boost loll I was pushing 25-26psi on the stock turbo pushed a good 400 hp it ran for a good while but it finally took a **** lollll but I also raced the car every time I got in it so I’m not surprised lol
I'll admit that mine is currently tuned at 24 lbs of boost, per my request. And if my car wasn't modified, I could be pushing as much as 40 lbs of Turbine Intake Pressure (that number is borrowed from a turner, who posted on another forum). However, I should be able to get some hard numbers in the next few months as I return to the track, equipped with an IMAP/EMAP sensor tapped into my ECU and developed by Jessie Ringley of EMS (engineered motorsport solutions).
You and your car, give me peace of mind! If it's good enough for Ford, it's OK with me! You have a good factory tune, and I have a good aftermarket tune. But there are a few guys with laptops pushing several ecoboost motors (with stock turbochargers) up to 29/30 lbs of boost, that's almost as crazy as telling someone to log thier motor while traveling at over 100 mph on a public streets!??
I agree with you on the peace of mind that 24psi is the safe limit for boost on a stock blocked eco. I had my FP tune since may of 2022 with just over 7K on the clock and now have right at 12K on it now with no issues out of it. I went on the Hot Rod power tour back in June that was a 1500 mile road trip thru hades with ambient temps of 100+ degrees every day of the 5 day trip and it never whimpered even getting stuck in a traffic jam from an accident in Atlanta idling with the A/C on for over an hour.
I definitely pushed those limits 🤣🤣 but nah 29-30psi on stock turbo is doable but it’s just to much stress you’re asking for it just blow up , you can push that much psi with an upgraded turbo but even then less psi on the bigger turbo makes more power my car was tuned several revisions to make more and more power I was running an e-30 mix as well on map slot 2 which is cool you can change with the steering wheel control what map you wanna run but at the end of the day the short block is it’s weakens once you pass 450 hp it’s doomed to ECOBOOM stock I was pushing close to 400. Hp but like I said I raced it every day loll I don’t have a daily bc I don’t go anywhere 🤣and I got a work truck so the only time I drove my car was to MASH the peddle loll but my boy who’s out Cali he’s pushing 400hp confirmed dyno on the stock turbo and turbo smart waste gate his motor is still stock he’s finally getting the nx2 he has the 10 speed its auto I know that but his has been healthy no ECOBOOM
Oh he’s also running the xdi 35 HPFP i Believe it’s the cheaper one so thats less stress there and he’s got catch cans , The first day I got the ecoboost I took it to Mexico to figure out it’s limit 3 runs was it before the stock interocoler over heated and my car went into limp mode since then I’ve been modding every little thing

Yep, I recommend getting one as well. Here is the same part also and is a UPR branded part but just comes in black only but 20 bucks cheaper.I would recommend getting the CFM Valve cover breather or similar to help prevent head gasket failures in the future. I have only ever used the CFM so that is the only one I can recommend.

CFM Valve cover breather observations and cleaning
A quick history, my 2015 was stock for 5 years and 40k miles before I started adding Bolt-on mods and an ECU flash. I had the notorious timing cover oil leak and front engine stain. I had previously cleaned it but it always came back. During my research I read some info on the CFM valve cover...
