I mean.... well.... no. Not really. Where did this parallax originate? It's peppered all over this forum and is disingenuous at best.Versus the 2.3 starting as a N/A engine with a turbo slapped on
Here's the explanation from @Jomo, which is correct:
A Ford Duratec engine is essentially a Mazda MZR engine which has a closed deck Al block, iron liners, forged steel crankshaft, powder metal rods.
The current Ford Ecoboost 2.3L is a totally revised design based on the twin scroll Ecoboost 2.0L. It is not the older 2.3L Ecoboost based on the MZR . It has a ladder frame reinforced open deck Al block, chromoly liners, forged chromoly crankshaft, forged steel rods. This engine has been used since 2015.
The engines are quite different.
