It’s unusual to have the words “muscle car” and “four-cylinder” used in the same sentence, but that’s exactly what’s going on here when it comes to the EcoBeast short block crate engine that’s available from Ford Performance. Going by part number M-6009-23EB and is listed with a price tag of $6,485, the EcoBeast engine fits itself in 2015 to 2022 S550 Ford Mustang, as well as the bygone 2016 to 2018 Ford Focus RS hatchback. Both of which already feature(d) a high output 2.3L EcoBoost engine from the factory – but not exactly this high of an output.
What makes the EcoBeast crate engine so special? It’s tested to 500 horsepower and 415 ft-lbs of torque. So if you want to surprise Scat Packs, this engine might be for you. How power dense are we talking? This inline four-pot turbo is capable of comfortably handling 84 more horsepower and 46 lb-ft more torque than even the famed Mercedes-AMG M139 engine, which goes on record as being the most powerful four cylinder to ever make into a production car.

Giving the Ford EcoBeast short block crate engine the fortifications to handle 500 horsepower consists of a Callies crankshaft that’s both 9-pound lighter than stock, and has been cryogenically stress relieved, as well as Mahle forged 2618 pistons. There are also connecting rods from Callies, and Compstar H-beam connecting rods w/ARP2000 rod bolts compliment the race ready engine insides. All of which are operating under a 9.5:1 compression ratio.
The Ford Performance EcoBeast short block engine kit additionally comes with an oil pump, a chain drive, a damper with keyway, damper bolts, an oil filter, and a head gasket. Out of the box, the engine comes with Ford Mustang EcoBoost motor mount bosses, but can be easily removed for Ford Focus RS applications.
Using the term “race ready” implies the engine is meant for race cars. The Ford Performance website does display a glaring warning that mentions the EcoBeast engine should not be installed on any vehicle expected to drive on public roads, stating that “this part is designed and intended for competition use only,” though we’re sure that disclaimer comes with a wink and a nudge.
