There is a guy on mazdas247 that calls his 5 the Bosswagon 7.0 and it is an auto trans with the mazda3 Tri-Point turbo kit on it. He says it'll outrun his chipped Cruze 1.4 turbo but I'm not sure how quick those are. He estimates high 14s in the quarter.
The kit could be a good option if it becomes my work commuter.
