Well I'm sure it's possible, however, is it worth the hassel. I mean, if your going to use forced induction, you will probably be better off going for an EL XR engine. There cheaper to buy, so you could spend the extra money on the induction system.
If I were to do it personally, I would rebuild the existing bottom end of the EA for max strength. Slap on an EL XR head and manifold, with some head work done. I would then spend the rest of the money on a Unichip and the induction system.
