See post 47, sounds like it is doable.Well it has been proven that the RS 2.3 is more stout than the Mustang 2.3.
That said, they are both fairly weak.
I'm looking at the 2.5 Duratec right now.
Closed deck. Girdle mains.
Would really like to know if the 2.3EB head will fit. I will have to use the 2.3 crank already.

From my quick glance at head gaskets for a duratec and ecoboost it definitely isn’t a straight swap. I would personally stick with the 2.0L ecoboost block as it is simple and widely done. There are far more high horsepower ecoboost builds in the focus ST forums than with mustangs. They run different intake manifolds and single scroll turbos but you will learn far more about block strength and overcoming fueling limitations as well as cams over there compared with here.
