Old NA 2.3 duratec, closed deck design for superior sealing. New turbocharged 2.3 ecoboost, open deck design for inferior sealing. They call it “progress.”

That's because the 2.3L Duratec is a Mazda engine and the 2.3 ecoboost is clean-sheet design from Ford.

They're used in older Focuses, the NC Miata, and a LOT of kit car builds like Caterhams. The 2.3 is a bit of an odd choice today since the 2.5 is available. The current trendy setup is to pair the shorter crank from the 2.3 with the bigger bore of the 2.5 to make a 2.4 build. That results in better bottom-end geometry than a Honda K24, and kicks ass until you start running into block limitations around the 500hp mark. The Duratec has had some attention from pretty serious players like Cosworth, Mountune, and Esslinger. Put it this way, it's not good enough to get put into an S2K, but it's too good to justify K-swapping an NC.
