hey guys I have a t-maxx 2.5 and I feel the need for speed and power. What engine would you recommend that would be a direct replacement and about how fast It will make me go? I heard the sirio is nice but I don't know if it is worth it because I don't know how much faster I will be going.
thanks

The Fantom .18 is pretty good, but really it won't go much faster.
get some new tires like 40's big rims and less rubber.
