Hello Tiago, and welcome
I didn't know that Fiat made a "sport" version of the 1.3 M-Jet, unless you refer to a 3 door car instead of a 5 door car as a sport?
On another subject, have you had any experience with TRW Performance, who are based just outside Lisbon? They list some interesting performance parts for the 1.3MJet on their website, but communication in English is somewhat difficult when I have tried
