Haven't seen too many guys with it, but they guys that do have it seem to feel that it's on par with the 3.3. Given how TRX engines tune... I'd lean towards the dynamite for something less frustrating.
Maybe it bored me cause it had no power cause i sunk it in a pond and overheated it one to many times! HA HA! Decided to give it another shot and bought the 2.5r today. Was going to go for the 3.3 but didnt want to upgrade drive line.
