Extra's needed include a new fuel pressure regulator, fuel pump, ECU.
This method has the advantage of not needing the engine removed from the car. Intake and exhaust can be accessed from above and below, while the block is in situ.
You can make your own front mounted intercooler or buy a WRX hood.
I would recommend sticking with a low boost 0.4-0.6 Bar, since the heads and pistons are high compression not suited to high boost.
A total engine swap is the best solution, but requires a great deal more work, and gives a power rise that DEMANDS new brakes.

turbo exhaust manifold
turbo crossmember (as it fits the exhaust parts needed. the n/a cross member doesn't.)
better injectors (IE: EJ22T injectors)
better fuel pump
engine management to piggy back and allow the higher fuel rate needed
but with just the bare minimum, we don't suggest 9.5:1 CR with more than 6lbs of boost without an intercooler on an open deck block.
you'll want -
lower compression pistons
fuel pressure regulator
this will allow you to run higher boost. like 10 to 14 lbs. I've seen and talked to plenty of people on various boards who try to demistify the myth that the EJ22E block won't handle 10-14 lbs of boost. It's not the block, it's the high CR combined with the block's open deck that makes you not want to run very much boost.
Through all my research, i've come to the conclusion that a completely stock N/A EJ22 block (stock heads, internals, block) is not a good choice. The EJ22E block in itself, in comparison to an EJ257 block like in the STi, has similar thickness in walls. I think that with low compression, good intercooling, and engine management, you could push 300hp from one of these blocks. but I don't know if that's raising the bar too high or not. I know the EJ22T block can handle 500+ hp with the right internals. some say with stock crank and rods, it's possible to hit 500+ in the EJ22T, but I don't know if the crank and rods are capable. The thing to do with an EJ22E block is change the pistons to forged EJ22T pistons or even have some custom ones made up - keeping the forged crank and rods. That's a good thing.
