Ford 2.3L EcoBeast I-4 Shortblock Out Now For Mustang, Focus RS Builds

Sponsored

The Ford Mustang EcoBoost and Ford Focus RS are both powered by FoMoCo’s 2.3L EcoBoost I-4, a formidable performance engine in its own right. Thanks largely to a turbocharger, the inline-four cylinder produces 310 horsepower and 350 pound-feet of torque in the Mustang, or 350 horsepower and 350 pound-feet of torque in the Focus RS. Now, the newly available Ford 2.3L EcoBeast I-4 short block is available to purchase through the Ford Performance catalog for those that want to extract even more power from those vehicles.

The Ford 2.3L EcoBeast I-4 short block utilizes a Focus RS block, but adds forged internals for greater strength and power potential. Those upgrades include a Callies crankshaft that’s been cryogenic stress relieved with an added keyway, which weighs nine pounds less than the stock crank, as well as Callies Compstar H-beam connecting rods, ARP2000 rod bolts, and Mahle forged 2618 pistons that provide a 9.5:1 compression ratio.

The EcoBeast block itself has been treated to deck cooling jacket inserts for additional bore strength, and features Mustang motor mount bosses that can be removed if the owner wishes to install the short block in a Focus RS. The kit comes with an oil pump, a chain drive, a damper, damper bolts, an oil filter, and a head gasket, which means customers can swap over all their top end components or upgrade those parts as well if more power is desired.

Ford says that the EcoBeast short block has been tested to handle as much as 500 horsepower and 415 pound-feet of torque, providing a sturdy base for a high-power build. The kit fits 2015-2022 Mustang models equipped with Ford’s 2.3L EcoBoost I-4, as well as 2016-2018 Focus RS models, and retails for $6,485.

Brett's lost track of all the Fords he's owned over the years and how much he's spent modifying them, but his current money pits include an S550 Mustang and 13th gen F-150.

    The 2.3 EcoBoost 350hp should have been a SVO trim level after the Focus RS. Another missed opportunity to sell more Mustang to fans who love that model

      Being a turbo car. if fans of the model want more horsepower it’s easily gotten via freer intake and a mild tune tweak. Ford Performance has been selling (With Warranty) the 50 states legal kit for over 5 years, and dozens of aftermarket shops do the same. 20-40 horses will not keep anyone from buying a Mustang, as if Mustang buyers were afraid of modifying the car.

      BTW It’s called Ford Performance, has not been called SVO in 28 years…

    The 2.3l ecoboost has a single twin scroll turbo, not two.

    So far quite good, but I like the V8 and what a small inline-4 turbo that breaks quickly!
    A 2.3L I-4 Turbo ICE with 500HP and 415 pounds of torque doesn’t live long to burn out. And how stable is the Focus RS drive? I think you should calculate that beforehand.
