Vortech makes a supercharger for the 2.5, but you're going to have to find a used one. Also, there was a company called Arizona Dyno (ADC) that recently went under, but there are a few kits running around out there. Check the contour.org or cougar forums for info on FI in the 2.5. Quite a few of them out there. Also, many people have upgraded the motor to the 3.0 duratec for a more reliable motor with a lot more torque.
