Torrents use HTTP by default, to transfer the data (and seed).
I'm not going to lie, I don't quite understand what you're wanting to do, here.
If you want to change the networking protocol that your torrent box uses, good luck. The main problem here, is that your torrent box still has to report to a tracker, for statistics and such. Every public (and private) tracker out there, uses the HTTP protocol as its main means of communication with the rest of the world. Hence, I'm pretty sure every torrent client out there only uses HTTP to send/receive information.
