I would definently water cool the turbo. Its easy ( T off your heater core lines) and it will extend the life of your turbo. Check out the diagrams page of northursalia.com. Thats where I got the ecu pinout for my SAFC-2. I'm running a similar setup with a wrx turbo but i'm using a fmu on stock injectors. What intercooler setup are you planning on using? You'll need to get a custom oil feed line made and weld a bung in your oil pan for the oil return line. PM me for any parts you need or ?'s. Good luck with the install!

yea notching the xmember works just fine just try to measure out the cut so you dont sacrifice too much strength. Definitly T those heater core lines for coolant its easy bc they are right there. The turbo will run much cooler even though i have seen people running them without, the turbo will not last as long in that case. Are you going to run an intercooler, I would recommend that you do in order to keep your intake temps down. The engine will run more safely if you keep those temps low.

Have you thought about the oil supply? that was the hardest part of the conversion for me. right now my mechanic is tapping the block on the new motor that i am installing in my car after the origional one blew due to a oil supply problem i had.

what is the compression ratio? on this block, I'm thinking about doing this. I just upgraded wrx and I think I might throw this into my daily driver (2.2 Legacy)

Also, does anyone know were I can get suspention upgrades for this car (wagon)?

N/A EJ22 CR is 9.5:1 its straight for a few psi prolly no more than 6 psi for stock internals.

EJ22T was 8.0:1 for 8.7psi

Another question, I've been doing some research, I read that this 02'+ WRX turbo components (the exhast manifold) will only cross over to 95 or lower EJ22 Legacy?

96 and up are single port heads and the WRX is dual. So this won't mate up with eachother? So what are my options? can I just change the flange to make it fit? Also does the brackets for the stock intercooler cross over as well?
Thanks for the input I'm really interested in this. I'm about to do a full tune up on the Legacy anyway(@ 75,000miles) .

that is generally correct although you may find some legacys with dual ported heads after 1995 but mine at 1992 is dual and i know all the legacy's from 1990-1994 were dual port so no problems running the wrx headers uppipe downpipe cat and midpipe it will need to be extended 1.5 ft though inorder to make it to the end
