Due to his sub-standard performances for Olympiacos in his first season, as well as the fact that he occupies a non-EU player spot at his current team's roster, Olympiacos had the desire at the end of the 2006–07 season to sell him or loan him for the upcoming season. Due to that decision by the club, Borja was loaned out to German club Mainz 05 for the 2007–08 season. At the end of the season, Mainz signed him permanently. Having limited success, especially after Mainz earned promotion to the Bundesliga, he transferred to the Mexican club Puebla  In the 2011–12 Apertaura season, he was transferred to Pachuca F.C..
On 24 January 2017, Felix Borja signed a contract with El Nacional. Previously he was a free agent.
He was included in the Ecuador for the 2006 FIFA World Cup, despite his relative inexperience. He played in several of the 2006 FIFA World Cup qualifying matches for the Ecuadorian national team, including the game against Uruguay which confirmed their passage to Germany 06.
