The ej20 and ej25 are the same physical size. The ej25 has a slightly bigger bore and longer stroke. Assuming the ft 86 will have some kind of ej20, so an ej257 from usdm sti would fit just fine and could produce well over 600 whp. That kind of swap has been done a million times. I am sure someone will come up with a kit that will fit in the intercoolling and exhaust for the turbo.
I think what is more interesting is what a built NA ej20 that is balanced and blueprinted could do. My built stroked ej20 can already rev over 8k rpm. Maybe 10k+ would be possible?
