Dood you can get them from JHOT on ebay for dirt cheap. Just be sure to look into the fact that you CANNOT TUNE THIS MOTOR. and the fact the TWIN TURBO SYSTEM BLOWS. I guess it might be fun to have power up until 4000 and then 500rpm of nothing while you're waiting for the second turbo to spool. The EJ20TT guys call this the power valley and if you shift and get stuck in it you may as well be in a D-series honda.

The internals are great on the EJ20R but the heads suck, the cams suck, the primary turbo blows out, and the secondary turbo doesnt flow enough for adequate topend. Not to mention the OP is the first person to successfully swap it into a LHD drive car. If you get to know Subaru guys, you'll learn that most anything that is reasonable has been done before, yet these shotty motors have been avoided for the latter decade, thats saying something.

Spend a little more and get a USDM EJ205. If you wait around for long enough you can get a shortblock for free and piece together a 2.5 block for less than $1500 including new pistons and rods.

EJ20R is the worst motor subaru has ever made IMO. I'd turbo a SOHC 2.5 before swapping in one of these, at least that would be fun until it blew up, this will last forever and leave you wanting more.
