The horsepower numbers are nice to have but IMHO they will not put a 6 cyl into the WRX. It seems most of the industry is moving to less cylinders. And the difference of hp numbers between the WRX and STi seem too high. I can see maybe a 60hp diff between the two cars but not 100hp. But this is all pure speculation on my part.
As I mentioned earlier, and this is more speculation, I would like to see a 270hp turbo 4-cyl in the WRX that weighs about 3000lbs. This should give a very practical and doable increase in power to weight ratio - with possibly a 0.5 second drop in 0-60 acceleration (all else being about the same). Less weight should perhaps give better mpg, and all around better braking, handling, and so on ... all else being about the same.
A 270hp turbo will be easier to do than losing 200 lbs! But I am hoping Subaru can make it happen.
