Sean, honestly I don't know about the internals....I know people are putting over 400 to the wheels on e85 with no issues to the clutch/transmission....depending on how you drive the car. The transmissions in the 08+ WRXs are the same found in Legacy GTs, and JDM 5-spd STIs. It's not the (problematic) transmission from 02-07 WRX.
Just a teaser....Got the intercooler on and trimmed the bumper/grille. The TurboXS fits like a glove, no issues what so ever. The GT Spec ELH, uppipe, motor mounts and trans mounts should be on either Thursday or Friday. Cant wait to see the header after the black ceramic coating.
