I'm less than a month from closing on my house and after selling it i'll pocket close to 24,000. Most will go towards paying off remaining credit card debt and my wife's 06 Tribute to lower the monthly note but I'll probably have about 8500 left to purchase a cobra. I'm wondering what mods I can make to get mid to low 13's maybe 12's without gutting the car or adding a power adder. What gears?exhaust?cold-air kits? how much will a custom tune help with simple bolt-ons? As I already have a 94 5.0 that i'll drive daily my ultimate goal with the cobra is a turbo from turbochargedpower.com (hoping for 550rwhp) Will a 4.6 block from an 01 GT work for a engine build up and do the 96-98 cars come with the aluminum blocks? Oh are 4.10 too much for the car as a daily driver?
