Well, the first thing you REALLY need to understand about the EG33 is that the aftermarket is non-existant. If you understand this, then that answers half of your questions right there.
No custom fuel rails, no specific pistons or rods, (the legacy 2.2 turbo pistons will supposedly work, however i don't know of anyone actually running them),
I'd suggest looking into closing the deck, however for 400 i'm not sure if this is neccesary. you may want to look into a custom headgasket... I'm not sure the stock will hold that much boost.


I think that you'd be much better off with the full standalone. however, you need to make sure that it will work with the type of ignition system we have. The coilpacks are actually "attached" to the individual spark plugs.

getting custom pistons and rods made shouldn't be all THAT expensive, but you're still looking at about 1000$

Good Luck!, have you seen the other impreza swap thats going on right now? its posted on nasioc
