my buddy has an '02 convertible with just the KB S/C and injectors. The car has about 415rwhp and about 500 some odd rwtq. For a daily driven mustang... and a sleeper no less... he has 20k on the blower, 60k on the car and it still drives reliable getting 15-18 mpg on the street and 22-25 mpg on the freeway because he did not change his gears. If you do not want to get taller gears get the KB. If you want taller gears get a Centrifugal with a cam and other modular tunes to get similar numbers. Trust me though... the KB by itself still smokes 04 zo6's. Im assuming this car does around mid 12's to high 12's depending on driver. I drove it, and it blew me away. I had a 5.0 with every modular mod you could do with tall gears and couldn't smoke him. I probably wont go back to the 5.0 motor now.
