Hey all. Been browsing around here for some time. First post.

I was interested in doing a complete upgrade on my '03 V6. Trying to get some ideas for what all that can be done to increase performance for minimal cost.. The main thing I wanted to get was a supercharger (Procharger). Some other things ive been thinking of:

CAI - what kind is best?
Dual Exhaust
Tires
Brakes
Posi?
Shocks

Other ideas?

What all would need to be added get these "features". Any cost estimates/links would be greatly appreciated.

EDIT: also, are there any performance details on the net that compare something like this to a stock mustang GT?

CAI...if ur tight on money ebay cheap one for $25 or a really good one K&N CAI
dual exhaust...i'd say get a full MAC set up, mac h pipe(mid pipe) mac long tubes and mac cat back.
tires? as in your getting new rims too?
17 or 18 x10.5 in back and 9 in the front..
posi/t-loc is a good addition (throw in some gears with it 3.73 or 4.10)
shocks i'd recommend ford c springs, drops ur car an inch in the bac and 1.25 up front, thats enough. if you want more, steeda springs are good.
another good bolt on is a 25% ASP Underdrive pulley. if u get that only get ASP pulley. its the safest choice pretty much. it'll give u hp and not make ur engine work as hard.

also a SCT XCAL 2 is a very good move too

Im just starting to get into the'stang modding world :p

But how much of that is possible to do with basic hand tools (mainly the posi and shocks).

Also info on tuning (how-to) link will help.

A friend mentioned the Nitto tires to me. Ill check those out.

Are there any other minor/easy modifications that can be done to improve performance or fuel economy.

you cannot do the rear end gears t/lok with basic tools.
you can tune by plugging the xcal 2 into the ovd2 port under the drivers side dash and load the tune in less than 5 minutes, no tools required except finger

CAI basic tools
UD pulley Basic tools
SCT XCAL2 basic...
brakes is also basic tools
exhaust, u can get what AB sed witht he long tubes and that exhaust and it can be done with basic tools but it'll take a while
(bolt ons are mods that can be bolted on wiht basic tools)
you have to rent a harmonic balancer puller or buy one to remove and reinstall the pulley

Just ordered a CAI on ebay. Should be here in a few days. Hopefully ill be able to install it w/o any problems :)

It was the cheapest one i could find on ebay. $45 after shipping and tax.
is it the bomz racing one? if it is and you have any problems with install, i can walk you through it with pics if needed

looks like the same design as the MAC fenderwell, with a little smaller of a filter. would sugguest looking at some of their stuff like their longtube headers, o/r mid-pipes, caster/camber plates, then maybe a tokico advance handling kit (lowering springs, shocks, and struts). then deceide on how much power you really want to put through it and either do a 8.8 swap or add the gears and t-lock to the 7.5

i got the same one....i regret it..after i drive fora while i touch it and its really hot...im really considering throughing back on my stock intake and K&B filter
not to bring you down but the next intake i get is either JLT or K&N yea its $150 but it does the right job
even though it gets hot it isn't really that bad, reach up and touch that upper intake manifold and see how hot that is which the air still has to pass through. also JLT only makes the intakes for the 05+ v6 mustang and the supercoupe.

the intake manifold is hot too...if i keep my car im getting a new intake manifold
good luck keeping a metal intake manifold cool whatsoever. the windstar manifold is a good stock upgrade, but a sheetmetal manifold with a correct volume and runner length is ideal

just know there is nothing wrong with an aluminum intake manifold, they also hold more boost than their composite counterparts. there are phenolic spacers that can fit between between the upper and lower manifolds that are suppose to help prevent heat soak while elongating the intake runners for added torque
