Battle Spirits Shonen Gekiha Dan (or some other show in the Battle Spirits series), Madö King Granzört or Albegas are my closest guesses.
Was there an English dub?

In general, I remember the CGI Mecha animated series, maybe an anime, but unlikely. There, the main character, at least in the beginning, could become smarter, thanks to the alien, who later became the antagonist. He was also in a team of three people, which was assembled by a short and fat guy, who led them to something like a stunt show, where the qualifying part was a test for assembling a disassembled 3D model of a robot, where the alien increased the intelligence of the main character so that he passed . And also the third there was a smart guy who, in this stunt show, ate carrots to think better, and his rivals slipped him a rat instead. Now, these are almost all the scenes that I clearly remember.
