There are two different T5's. You don't want the Borg Warner T5 that came out of the S-10s. Even though it will bolt up to a V8, it can't take as much abuse as a T5 out of a Mustang. I'm not sure what years or models of stang it came out of. I just had this conversation the other day with a buddy of mine. I asked a couple people afterwards, and they all agreed with him. So, the general consensus is go for the stang's T5.
