Agreed. For what it would cost you to pay someone to beef up your WRX tranny with stronger gears you probably could just get an STi tranny and be good up to 700+ HP. Not to mention another gear which is nice for highway driving.

If you want to do the work yourself and save money, I have heard *rumors* that there are kits for the WRX tranny that beef it up almost to the STi strength level. Ive never seen one, like I said... rumors. That could be an option, or it could be more expensive. Who knows! I am doing a swap into my suby, so I am also shopping for an STi tranny so I understand where your coming from since my stock Legacy tranny is as about as strong as the transmission on a Model T let us know what you decide to do and we will all help you get your suby to where you want it to be!
