Alright, i have an 04 GT. i work at a ford dealership so i get discounts like crazy through ford racing. when i purchased my mustang i didnt have the money for a cobra, or the insurance on a cobra. but i really want one, i love everything about the cobra's. is it possible and what would i need if i were to do a cobra 4.6L 4v DOHC supercharged engine. Would i need a new computer, wiring harness, etc.? I will end up paying about $6,000 for the engine, which isnt bad at all considering it retails for over $11,000. I know im ganna get a lot of its not worth it, just build the bottom end up on the GT throw a kenne bell, vortech, and other superchargers on and you'll be smoking cobra's. i agree, but i already have a cobra body kit because i think the appearance of a cobra is astonishing, i love the looks of them, and the interiors are just even more nicer with the suede interior. Alright back on track though, please just reply and let me know what i would need. Thank you very much
