Does anyone have any detailed info on how they get 296HP/295lb-ft from the WRX S4? I saw the subaru japan website but couldn't find anything helpful. Especially since I can't read Japananese.

Change the tune, I'm sure.

It's crank horsepower, so it's really not a very big bump from the normal WRX.

The Japanese website states torque in non-SI units?! That's disgusting.

Modified intake and exhaust parts would be my guess
