Hey Guys,

Just wondering if anyone would know what the max power is that the box on the 06/07 STI can take?

Thanks in advance =)

what kind of abuse are you putting out? Id say that the diffs need to be upgraded if your talking over 450whp

If your having issues turning slowly or turning in reverse or you hear some groaning in reverse then your having center diff issues. My last DD STi had a bad center diff and I was tuned at 309hp I dont know what the previous owner had done since it had broke before I even bought the car.. But I think that is pretty uncommon at that power level.
