EcoBoost series are turbocharged gasoline motors with direct injection, manufactured by Ford. The debut motor of this type was a joint venture of FEV Engineering (Germany) and Mazda (Japan). Ford 2.0-liter and 2.3-liter motors are turbocharged modifications of Mazda L motors.

Motors of this range were created to reach the identical efficiency with naturally aspirated motors featuring cylinders with larger capacity, but, simultaneously, reduce the fuel consumption and emissions. Basically, the producer asserts that this motor consumes 30% less fuel and is 15% more eco-friendly. Seeing the EcoBoost technology as more affordable and miscellaneous than it’s hybrid and diesel rivals, Ford applied it for a great number of its automobiles.

In 2015, Ford presented its 2.0-liter EcoBoost Generation Two along with the 2.3-litre variant, the largest 4-cylinder motor of the range as well as the strongest one. In 2015, the 2.3-liter I4 turbocharged motor appeared. Initially, it was employed for 2015 Lincoln MKC crossover and the next year, it was utilized for Ford Explorer and 350 hp Ford Focus RS.

However, EcoBoost reached popularity thanks to Ford Mustang, producing 310 hp and a torque of 320 lb/ft (434 Nm). To the point, Mustang SVO, released in the mid-80s, was the last automobile of the brand, keeping a 4-cylinder motor with turbocharging.

High-quality Parts

Substantially, the EcoBoost with 2.3-litre displacement was built on the framework of 2.0-liter EcoBoost Generation Two and is often denominated a “stroker”. Though these motors are manufactured at the same plant in Valencia (Spain), the 2.3-litre modification was strengthened to cope with greater power and have better endurance.

This motor keeps an aluminum cylinder block featuring a die-cast open deck. Having the identical bore size and deck height with 2.0-liter EcoBoost, the block of the 2.3l Ecoboost variation keeps larger oil and cooling passages plus structural ladder frame (fortifying ribs formed around the cylinders), comprising integrated main bearing caps.

Fresh forged 4340 steel crankshaft featuring 96 mm stroke (comparing to 83.1 mm stroke in the 2.0-litre motor) allowed increasing the capacity. Besides, it gained shorter forged steel connecting rods plus lightweight pistons having steel piston ring carriers plus floating pins.

More efficient lubrication and reduced friction are achieved thanks to updated pistons with low-friction skirt cover and fewer amount of oil drainage ports. Oil, which is spread by the block by special oil jets, cools the cylinder underside. The motor bottom comprises oil pump controlled by a chain, balance shaft plus die-cast deep-sump aluminum oil pan featuring a baffled surface for oil slosh prevention and oil delivery maintenance under active driving.

An aluminum cylinder head, located on the block upside, keeps 4 valves, 1 GDI fuel injector and spark plug for each cylinder, 2 double overhead camshafts controlled by a chain. The structure of the cylinder head supplies the exhaust manifold with 3 high-flow ports for the updated twin-scroll IWG turbocharger. While the 2.0-liter motor has 28 mm exhaust valves, its bigger version contains ones of 30 mm. The intake valves are 32.5 mm. High-efficiency materials were utilized for valve seats.

Being managed by Ford’s Twin independent Variable Cam Timing system, also called Ti-VCT, camshafts got higher lift along with better duration. Simultaneously, the exhaust camshaft ensures the functioning of the high-pressure fuel pump (cam-driven fuel pump or CDFP).

2.3 EcoBoost received a modernized plastic intake manifold with bigger volume and a throttle body of bigger diameter. A twin-scroll turbocharger provides an immediate boost as soon as it’s necessary. Additionally, it grants a flat torque curve much faster than a classic turbocharger. Consequently, upgraded intake details provide more power and faster acceleration reaction, producing less emission, improving turbine performance plus reducing turbo delays.

Engine oil check

To check the engine oil level consistently and accurately, do the following:

  1. Make sure the parking brake is on. Make sure the transmission is in park (P) or neutral (N).
  2. Run the engine until it reaches normal operating temperature.
  3. Make sure that your vehicle is on level ground.
  4. Switch the engine off and wait 15 minutes for the oil to drain into the oil pan. Checking the engine oil level too soon after you switch the engine off may result in an inaccurate reading.
  5. Open the hood.
  6. Remove the dipstick and wipe it with a clean, lint-free cloth. Replace the dipstick and remove it again to check the oil level.
  7. Replace the dipstick and remove it again to check the oil level.
  8. Make sure that the oil level is between the maximum and minimum marks. If the oil level is at the minimum mark, add oil immediately.
  9. If the oil level is correct, replace the dipstick and make sure it is fully seated.

Note: Do not remove the dipstick when the engine is running.
Note: If the oil level is between the maximum and minimum marks, the oil level is acceptable. Do not add oil.
Note: The oil consumption of new engines reaches its normal level after approximately 3,000 mi (5,000 km).

Adding Engine Oil

Do not remove the filler cap when the engine is running.

Do not use supplemental engine oil additives because they are unnecessary and could lead to engine damage that may not be covered by the vehicle Warranty.

Only use oils certified for gasoline engines by the American Petroleum Institute (API). An oil with this trademark symbol conforms to the current engine and emission system protection standards and fuel economy requirements of the International Lubricants Specification Advisory Committee (ILSAC).

To top up the engine oil level do the following:

  1. Clean the area surrounding the engine oil filler cap before you remove it.
  2. Remove the engine oil filler cap.
  3. Turn it counterclockwise and remove it.
  4. Add engine oil that meets our specifications. You may have to use a funnel to pour the engine oil into the opening.
  5. Recheck the oil level.
  6. If the oil level is correct, replace the dipstick and make sure it is fully seated.
  7. Replace the engine oil filler cap. Turn it clockwise until you feel a strong resistance.

Note: Do not add oil further than the maximum mark. Oil levels above the maximum mark may cause engine damage.
Note: Make sure you install the oil filler cap correctly.
Note: Soak up any spillage with an absorbent cloth immediately.

2.3 Ecoboost Twinscroll Turbo

2.3-liter motor is the premier motor of the EcoBoost line equipped with a twin-scroll turbocharger. The unique cylinder head keeps a three-port integrated manifold construction, separating inner and outer cylinders into each inlet passage on the turbocharger.

Twin scroll turbochargers guarantee a broad, flat torque, emerging when you stand on it – just the way Mustang fans suppose it to be. Consequently, spool and torque function faster than classic turbochargers while the acceleration reaction is related to the throttle stance. The extra advantages are lower emissions and refined turbine performance.

For better breathing and higher power in Mustang automobiles, the big plenum tapered runner intake manifold plus separated split-pulse twin-scroll turbocharger body were enhanced. Thus, the drivers, who seek for high-performance motors able to consume less fuel, get exactly what they want.

Ford 2.3 EcoBoost Problems and Reliability

2.3 EcoBoost is a heavy-duty turbocharged motor with direct injection, created for drivers, who can’t imagine their life without speed driving. Consequently, the endurance of many details may be shortened in comparison with naturally-aspirated motors.

Leakage of the head gasket is a rather common trouble of these motors in Ford Focus RS vehicles. First, you may notice white exhaust smoke plus excessive coolant consumption. But, afterwards, you may face misfiring under load or on a cold start, a sweet odor of the coolant in the exhaust, motor overheating and loss of cabin heating.

All those malfunctions are a consequence of utilizing the wrong head gasket, the one for Ford Mustang. Basically, the motor must have special gaskets as 2.3-liter EcoBoost features identical styling but other coolant passages. Besides, bear in mind that head gaskets don’t leak in Mustang motors.

GDI motors, including 2.3 EcoBoost, may face some output loss. The malfunction is accompanied by reduced efficiency and higher fuel use. The reason for that is the concentration of carbon on the back of the intake valves and intake ports walls. What’s more, the carbon black layer limits intake airflow and averts intake valves from proper closing. The resolution is to clean the motor from carbon black by initiating the special cleaning process.

24 thoughts on “2.3 Ecoboost Engine

  1. I just purchased a 2016 Ford Explorer limited w/ ecoboost:
    When the car is initially driven if feels like the transmission may be slipping.It does not transition to each gear smoothly. Is this because of the eco boost?

  2. Dan Hoffman says:

    Hi! What’s the mileage of your Explorer? It doesn’t seem like it’s somehow related to EcoBoost. I’d rather visit my dealership or customer service to check the transmission.

  3. Hi Dan,
    I’m looking at Mustang EcoBoost to use as a daily driver.
    Read somewhere that this engine will start losing power in 4-5 years and it’s much better to go with GT (5l).
    What do you think about keeping Mustang EcoBoost for more than 5 years, how do these 2.3l engines age?
    Thanks a lot!

    1. Dan Hoffman says:

      Hi! You know that thing: “No replacement for displacement!”)) That’s a major reason to go with the 5l engine. But, generally, it depends on how do you maintain your engine (and a whole car). Please, understand one thing: The Mustang is a dream car, and first of all, it’s a muscle car, so they were driven aggressively. And after 5 years of this, you want to buy such a car? That’s the first thing.
      The second one: comparing these two engines, they have the same set of problems and after 5 years of use it is more like a lottery. Whatever you choose – prepare for problems. But in this case, I would prefer to mess with the 5L engine.

  4. Thanks for your reply!
    I’m looking at new Mustangs and always maintain my cars more than required 😉

  5. Michael Micallef says:

    HI Dan, I periodically use “BerryMen” chem tool in my 17 year old Maxima. Valves are spotless. Would this product work as well in the 2.3 Eco-Boost Engine.

    1. Dan Hoffman says:

      BerryMen, CRC or Seafoam – all are good enough. But cleaner should be designed exactly for Turbo engines. This one is exactly right – https://amzn.to/2VZNlzM

  6. There was some opinions that the spray cleaners may damage the engine. What do you think?

    1. Dan Hoffman says:

      It really does not matter if the outside of your engine is dirty, but it’s important that the inside of your engine is clean. Generally, cleaners are not supposed to harm. As long as you use good gasoline and change the oil regularly – you do not need to use them.

  7. Jack Hyde says:

    I’ve heard that using these chemical cleaners could damage turbos and may void warranty. I have the 2.3 in my explorer. Any experience with turbo damage or was that a ploy to get us to the dealership?

    1. Dan Hoffman says:

      It is not allowed Under the Ford Warranty.
      I don’t think it could harm: the theory is that If a solid chunk went through a turbo it could POTENTIALLY cause damage but the likely hood of this happening is slim to none. I’ve never seen this in my life…
      Your experience may vary but this is my opinion.

      1. Sarah Alderman says:

        Our 2018 explorer 2.3 I4 eco boost is fluttering when around 2000-3000ish rpms. Almost like julting /jumping.

        Only 20k miles on it.
        And we are on a road trip currently so any ideas? Also seeking out the nearest ford dealer!


        1. Dan Hoffman says:

          I hope your dealer wont say: “It’s a usuall thing, so everything is fine”))
          Basically, if it “comes down” after it warms up – I would not be panic. In other case – ypu should check for the errors and visit your local dealer.

  8. Bill King says:

    I have a new 2019 Ranger with 500 miles on it. So far it is great, 25 MPG locally and lots of power. I generally go gently for the first 1000 but I had to punch it to pass the other day and it was suppressing. Because of the Direct Injection should I install a catch can? If so which one should I use?

    1. Dan Hoffman says:

      Yes, you should install it. I would recommend one from the UPR or Mishimoto.

      1. Bill King says:

        After looking at my Ranger more and looking on line, It has an oil separator in the PCV line. Does that mean I do not need a Catch Can?

        1. Dan Hoffman says:

          I think you can wait until it starts leaking and then replace it with much more efficient.

  9. What’s your opinion on an oil catch can for the Ecoboost?

    1. Dan Hoffman says:

      I would recommend using cans from the UPR. They are just great and easy to install.

  10. How do you set the timing on this engine there are no marks and the intake camshaft phaser bolt snapped it half. So the phaser spun without moving the camshaft. Replaced all the valves and seals and got everything back together but can’t set timing.

  11. dominic giacci says:

    Hi Dan long story short,,thinking about purchaseing the new Ford bronco it comes with an optional 2.7ecoboost engine,,i ve read that there are issues with the oil pan leakage? Apparently its been an issue for a while,,,

    1. Dan Hoffman says:

      Despite multiple repair attempts, the oil leaks keep coming back and cannot be fixed. While the oil leak might stop for a while, even for many months, the oil leak keeps coming back.

  12. According to Ford engineers, induction cleaning will cause turbo damage. It is not fron the gunk going through the turbo but the increased turbo temperatutes caused bu buring the richer mixture. This was confirmed by testing not opinion. But this is a free country and everyone is free to do what they want to their own vehicle.
