I note that the MY09+10 WRXs have 41 HP more than my Turbo Forester. Whatever differences there is between these two engines is interesting as it is likely a conservative method to get substantial extra power for the Forester.
Does anyone here know what provides that extra 41 HP???

Bigger turbo.

in addition to the larger turbo I'm sure they are tuned differently.

I can't wait for wrx and STI guys to start upgrading their stock turbos cheap turbo upgrades for the rest of us.

FXT--TD04
WRX--VF52(basically a vf48 off the sti, with different compressor housings)

they also have a more favorable final drive ratio. the 4.44s of the foz suck for dragging...
