My t-maxx 2.5 has had a 3.3 engine installed and the only upgrades to any other part was upgraded differential gears and bearings. Not sure what the gears are exactly. Then the slipper clutch upgrade whitch I am expecting any day to install. Due to the bigger motor on the 2.5 chassis and tranny what else would be a wise and necissary upgrade to the vehicle to be able to better handle the bigger motor?:\
You will need to learn a little throttle control once you get the 3.3 broken in and tuned with the short 2.5 chassis. Otherwise you will be landing on the lid or looking for a wheelie bar.
