If I wanted to add power to a 2.3L 160hp Duratec engine (Ford Fusion), what would be the cheapest way for me to do so? I emailed draxas, since they are doing "Project Fast Fusion" for SEMA 2005, and they are using a modified Mazda3 Turbocharger from Hiboost that runs $4200. If I want to spend less to get some good extra ponies...possibly in the 220-250 range, what would I need to do? Any suggestions would be great.
