The F-150s and transverse 2.7s were 99.9% the same up until 2017? or whenever Ford went to split-injection on the trucks. They shared the same engine internals, etc... but the turbo packaging and oil pan orientation was obviously different. The 3.0 debuted on the Lincolns (MKZ and Continental). I don't believe the Explorer ST is split injection, so it probably has a lot more in common with the transverse 3.0s than the current pickup 2.7. The oil pans may differ with the transverse based on the drain plug location, but the sealing surface design is the same.
I have heard of Fusion Sports getting their pans resealed/replaced recently where the dealer said there was a new design that they are not using as replacements until the old design is consumed.
FWIW the stock turbos on the Explorer ST are amazing based on their compressor map. Not surprised at all when they are running low 12s when tuned.
