ke17rolla

I'm looking at converting my ke17 sprinter and dropping a 13B into it. I was just wondering if you guys can point me into the right direction in terms of gearbox and diff. The car currently has a T50 celica box in it, would that hold up behind a 13B or is another box required? If so what would you guys recommend? Also, any recommendations for what diff to run? Not looking at running ridiculous power at the moment but might go down the turbo path in the future. Cheers
