The 2.3l EcoBoost engine of the new Ford Mustang

Specifically tuned for use in Mustang, the all-new 2.3-liter EcoBoost® engine brings the performance Mustang drivers expect and the ability to deliver projected improved fuel economy. Turbocharging, direct injection and twin independent variable camshaft timing are projected to deliver more than 305 horsepower and more than 406 Nm of torque.

This engine is the first Ford engine that uses of a twin-scroll turbocharger for more power and quicker acceleration response. It also integrates high-flow cylinder head with integrated exhaust manifold, forged steel connecting rods and crankshaft, steel piston ring carriers for better durability and balance shaft for vibration-less operation.

Regarding the twin-scroll turbocharger, delivering two separate exhaust streams to the turbo preserves pulse energy for quicker torque delivery when the driver needs it for passing maneuvers and similar performance to a twin turbocharger configuration.Twin-scroll turbocharger

The base engine includes light weight, high-strength pistons with low-friction skirt coating and cooling jets. The connecting rods have full floating pins. The cylinder block is made of high-pressure die-cast aluminum and it includes a structural ladder frame with integrated main bearing caps. Finally, the deep-sump oil pan is in die-cast aluminum with baffles to help maintain oil delivery during spirited driving.Ford EcoBoost 2.3 liter gasoline engine

Romain’s opinion:

This is a clear proof that USA market is following the way of downsizing. 20 years ago, US cars engines were mainly V8, even more in sports cars like Mustang or Corvette. 10 years ago they have switched to V6 engines, and now we see 4 cylinders coming in this kind of cars. Do you think customers will buy the Mustang with this engine despite the fact that it has much less torque than the V8 5.0l engine which is also in the catalog? I still think this is a strong message coming from the US manufacturers.

    1. Could this engine be fitted to a 1987 Thunderbird Turbo Coupe based on size and displacement? And if so, will it work for an automatic based on such horsepower?

    2. Original question! I think it could be done as 1987 Thunderbird automatic was also equipped with a 2.3l engine (150 hp). However, automatic transmission, rear axle and brake system should be adapted to handle the torque excess from the new 2.3l engine (300 Nm to 400 Nm).

    3. I think there will be people who will buy this car. I own a 2014 Ford Fiesta ST, and love it. I would also like to see Ford sell the Mustang 2.3 liter drivetrain on their SVO catalog. I am eyeing a 1952 Ford Anglia, that this drivetrain would fit nicely into. I now own a 1965 MGB with a stroked out 302 (347) in it with a 5 speed and a 9″ Ford rear-end. It’s an exciting car.
      I also own a 1950 Ford coupe (drag car) with a 428 Cobra Jet engine in it
