Ok, I know the car isn't even out yet, but just for grins and giggles how difficult/expensive would it be to boost the Sti up to a full 300 hp? The current consensus seems to place the car at around 260+- hp when it (hopefully) gets here. So that would mean adding 40 hp (note how comfortable I am at this higher level math). What would be the best way to add this horsepower taking into consideration $$, driveability, longevity.

Also, would a hp boost of this level necesitate(sp?) mods in the brakes, suspension, or exhaust to maintain the overall performance balance of the car?

Finally, what performance would a 300hp STi be capable of?
