2004 gt

[famousone]

I'm about to buy a 2004 mustang gt. Im new to the mustang family , my friend just recently got me interested in it and i wanted to know what would be the first performance upgrades i should purchase for it.

welcome to M.E. most people start with the basics like CAI and cat back exhaust. than you can move on to gears and a tuner and go from their. but it all depends on what you want to do with the car.

exhaust and a shifter (dont buy an auto... if its an auto keep on looking)

if you have the money go supercharger, if not there are all kinds of websites like ninosports, etc that sell the CAI, underdrive pulleys, exhuast (i would suggest going headers/manifolds back instead of catback), etc.

im pretty new too, or maybe just still green but gears means rear end gears right? will that make you ride higher rpms for the same speed (higher rpms on the highway with the diff gears)? and what does a tuner do for you?

Got me an 04 GT. First up for me, and most, was the CAI. Next, exhaust...

but yeah, all depends on what you want the car to do.

exhaust first than cold air kit trottle body and tune thats what im doing under 1500 dollars for a added 70 to 100 hp

It does mean rear end gears and you are correct about the higher rpms. Gears don't give more horsepower but better acceleration, and even a few mpg in town. Most people say 3.73 for stick and 4.10's for auto. The 4.6 can rev better than a 5.0 so even 4.10 in a manual is great, thats what my dad has and its awsome. A tuner will re-program your computer and unlock some horsepower and torque, and if you get gears you can re-program the computer to correct the speedo, depending on which tuner you get.

i put CAI on my 04 GT and am looking at a new throttle body and exhaust. but ive heard that a performance underdrive pulley adds some significant power assuming you're not addin a SC any time soon. (please lemme know if im wrong.)

[SpectorV]

most bolt ons will give you less than 10hp/tq I would say a cai is worth about 7hp/tq on a gt and exhaust is about the same. The UDP will also be right in their~

[Arron's racecar]

and is it true that a throttle body adds hp?

[rwboring]

guys help me out here but ive always heard that CAI arnt worth the money to just get a drop in spend the money elsewhere... such as pullies...

[lowering kit]

thats what everyone on the forums says (CAI doesnt add any HP)
they do look cool though

[rwboring]

once again personal preference but i think id reather spend 200$ on a better sounding exhaust or a set of lowering springs to me thats a better look then a CAI
