This site seems to have the most up to date info and HEAPS of pics, some interesting info there too.
Looks like it IS a boxer buy NOT an ej20 maybe? It looks similar but I am not too sure, they say it is an evolution of the engine used in the 2014 forester, was that an ej20 with a few new bits added or was it an all new boxer engine, I dunno?
