I've stated my point quite clearly. I think he'll be better served (money and time) to either go EJ205 or STi/FXT/LGT longblock swap. It is most probably that his EJ22 block with RS heads isn't going to dyno spectacularily better than an EJ205 dyno (if at all). It certainly won't be any stronger, as it has those same toothpick rods (which is the limiting factor for making power on both blocks). Not only that, the displacement is just bore, so you're not really going to get a big jump in tq like you would with the EJ25's.
I looked into this a lot when I was going to build project "22C" a few years ago.
Again, my $.02
