Here is what you need:
EJ251/3 (Phase 2) block + EJ25 head gasket
Your stock heads + Delta cams
That should put you in the 180-200 hp range with 200+ torque.
hmmm. Another interesting thought. I think I would have to use the ej25d though because pistons on the phase II ej25 do protrude slightly from the deck. I have done quite a bit of reading on the high cr frankenmotors in the past but for some reason I don't like it.
In all honesty I would sooner swap a full ej25 in than do the frankenmotor.
