The 2.3 RS engine needed a recast in order to make it a RWD application. That doesn't mean Ford did anything other than recast the RS block for RWD applications. If Ford made the RS engine stronger that is great. I wasn't aware of any issues with the RS engine that needed to be fixed. I watched the video and read Carl's comments but didn't get the impression that they made any significant changes to the block itself other than recasting it for RWD applications. The pistons, Turbo, etc. are a different subject.Correct. Re-casted was the term I heard from a reliable source. Which is exactly what Carl suggested, that Ford Performance shored up some shortcomings in the 2.3 block, to make it more robust and stronger. And while at it, added new pistons and added a bigger turbo so that the 2.3 can stretch it legs.
So, the rhetorical question remains, if everyone is using the 2.0 block for re-builds, doesn't Carl & Ford Performance also know this? So if Ford went through the effort of a re-cast, then I am sure they corrected a few weak spots, since they have access to CFD, etc.
So if recasted, only a fool would suggest they didn't add a little more beef where needed.
