the 2.2/2.5 motor should actually swap over and vice versa...you may have to do some motor mounts up though and wiring would be a headache...but physically fit and bolt up to the tranny...yes, you wouldnt get too much for that motor BTW, I just threw away my old DOHC block the day before yesterday, they are only really in high demand to SOHC people afraid to swap to the 2.4, I would love to see one in an omni though...it would be funny as hell
