Time to start playing Lego engine builder.
FWIW, the big bore delta likely means the bore spacing is different, meaning FA and EJ heads-n-blocks will have to stay in their own family.
Now, the FB20 has a 84mm bore with a 90mm stroke. Since Toyota/Subaru have admitted the FA is a derivation of the FB. We might be able to drop-in an FB 90mm stroke crank into the 86mm bore and end up with a whopping 2.09L and the reduced ability to rev.
The FB25 also has a 94mm bore, just like the EJ25.
