For 1997, Bouresche and Jabouille went international, purchasing a Porsche 911 GT1 to race in the brand new FIA GT Championship, with Emmanuel Collard and Jürgen von Gartzen, also taking part in Le Mans.
In 2001 they switched full-time to GTs, winning the N-GT class in the FIA GT Championship, once more with Terrien and Pescatori, who also won the title in 2002.
However, the French team used the car developed by N.Technology, more troublesome than the Prodrive version, and drivers Pescatori and Boris Derichebourg were only competitive after upgrading to the 575 GTC.
The team scored third place in the FIA GT Championship with two 575 GTCs, in spite of a lack of consistency due to several drivers changes, but still won the Donington race with Karl Wendlinger and Jaime Melo.
JMB also took the Drivers title in the Le Mans Endurance Series with Roman Rusinov in a 360 Modena and was third in the Italian GT Championship, with the old 550 Maranello.
