This post is getting a little bit silly.
Let me lay it down for you. There are no turbo EJ SOHC engines available in Australia. Only factory one I have ever heard of is the USDM EJ22 turbo, it was also missing an intercooler and apparently wasn't much of a motor.
The early Legacys came with the EJ20G motor, they were DOHC and had a water/air intercooler. The GC8 WRX's came with an EJ20G too, I beleive the heads had slightly better lifters that didn't suffer the oiling issues that many of the early Legacy motors did. These motors came with a crappy little air/air intercooler. The next motor was the EJ20K I think, from there things get a little hazy for me as I haven't ventured that far yet.
To fit an EJ20G you will need to cut the chassis rails. I don't understand why people focus so much on the chassis rails being an issue when the far greater and more important issue is the butchery you have to lay to the engine crossmember to clear the up-pipe. You have to do this to fit any turbo motor to a non-turbo car. Only other option available is to fit a crossmember from a factory turbo, best of luck locating one of them for an MY.
The wiring is something that is better done by someone who knows exactly what you want to do with the car. An auto-electrician will most likely butcher up your loom and not get anywhere with it. You really need to sit down with a wiring diagram and pick through it yourself IMHO.
All through this post I see reference to using EJ motors and EA transmissions. All well and fine with the NA stuff (although I personally feel the flywheel slotting is extremely dodgy) but for the turbo it is simply not a consideration. I don't care if anyone here says whats-his-name has an EJ20 turbo mated to a 5spd DR L series box, it's not going to be a reliable or lasting thing. The easiest and best gearbox to use behind a turbo EJ motor is the turbo pull clutch type box. You get a clutch that can withstand the pressure and you also get peace of mind.
Really, after having a good re-read of this post I have to backtrack on my previous statements regarding the EJ conversion, in your situation you really are better off with working up the EA81. Bolt on a Weber and put wide gapped plugs and a sports coil in it, then get an electronic dizzy. EJ conversions are huge undertakings, by far not the simplest introduction to the world of Subarus and really only something an enthusiast can appreciate. Plus if you're really only into how a car looks then there's not much point in making it go faster. Won't help those carpark stereo sound-offs ala Fast & the Furious at all.
Bring on the flames.
