I sort of liken it to how GM has the LS in everything from luxo-cruisers, work trucks, sports car, etc, all just packaged a bit differently.

If we look to 2007ish in Subaru history, the EJ25 NA, EJ25 Turbo, and EG36 were the only motor options.

Now, we have FA20, FB20, FB25, EJ25 turbo, EG36, it's really unnecessary.

Even simplifying it to a product stack like 07-ish would have huge cost savings. I still can't believe the EJ25 is still in production.

Simplifying it to a 2.0l and 2.5l block, both built to take boost, and using a variable head casting I *think* could make a lot of sense in simplifying the product stack.

Yes!
This is why I have a hard time believing there is a 2.4 in the works. A company doesn't try to streamline all their cars to one platform and then start making different engines for each and every one of them. They already have a lot of money invested in developing the FB engines so I don't see the case for building yet another type.
Could be totally wrong but we shall see eventually.
