fully built

A word used by people who have little or no experience with engines to attempt to describe how much work has been done to their motor. It usually implies they have done all the work possible to their motor and it is now at its maximum potential. Their credentials usually include having watched one or more of the Fast and Furious movies, several times. Although automotive engineers are constantly "building" and rebuilding their engines to improve performance, the people who use the term "fully built" feel their motor has reached its maximum potential after swapping out their cam gear with an awesome looking blue one they saw in Modified Mag. Additionally, the people who use this term will often detail all of the modifications (carefully noting the brand name) to their car even though all you asked them was: "What do you drive?"
