I think it will not fit, cause the FN2 fueltank-construction underneath the front seats.
An EP3 have a flat floorpanel and the fueltank is underneath the rearseats.
if you have the FN2 seats with the sliders, you just have to weld on new connection points on the sliders to mount them on the original points off the car (where the original seats were bolted on).
That is what I did with the Evo IX seats and it works absolutely fine.
I believe the FN2 seats can be done the same way.
