Turbo diesel engines, which use a form of direct injection, typically have compression ratios greater than 15:1.
If they tune the direct injection to delay when the fuel is injected, you can avoid detonation. Not sure how that would be different from a diesel, other than the type of fuel, though.
Of course the block has to be able to handle it, but subaru already makes a turbodiesel outside the US, so maybe the FA block can take it.

if you are going to go with a different block why not just build the block that came with the car? seems dumb to me to go and find a different block to handle the boost when you can just build what you already have.

have you ever driven a car with over 200hp? once you get a taste of that power you always want more and more....
