Ok so I just bought a 2001 mustang gt convertible about a month ago. I live in Michigan so I got to drive it for about 2 weeks before I put her away for the long winter but now I have a little extra cash and want to make some upgrades. I need advice on what I to do. I was thinking a PI intake manifold along with a 75mm throttle body (is that too much even if I put a supercharger in later on?) and plenum. I would add a cold air intake as well. What do you guys think? What kind of exhaust should I do? Any info and opinions would help.

lol. I was hoping to start with some simple things and only spend $1000 or so. at least for now.

well whats your furture plans for the car? staying n/a? power adder? what times do you want to see? what power numbers? a lot goes into this.

Well what I really want to do is put a supercharger in it. From what I understand I can get around 400 hp with certain types. I would be content with that for quite I while I think.

Your 01 already has all the PI goodies from the factory (not sure if they can actually be considered "good"). I wouldn't waste the money on an CAI as you won't gain anything from it besides a cool sucking sound. Exhaust is up to you, you need to decide what sounds best; go on youtube and start listening to clips.
What exactly are you wanting from the car?
I would do springs and shocks/struts so it handles and looks better, midpipe + catback.
That will give you a little of everything. A tad more go, a little more show, and some fun in the corners.
If just more go is what you want get some gears.

you are correct sir! my car made 380 rwhp and 383rwtq with a p1sc. 400 whp is a very obtainable number with a blower. although boost is fun, don't get too happy, when you boost a stock motor it becomes a time bomb, push it too much and it will blow. with that being said, mods to get the air in and out faster is always a good idea. a throttle body and plenum is a good idea along with a intake manifold. some headers may be good for you too, but if you don't install them yourself you will get raped on labor. gears will make a very big difference in your car also, a set of 4.10s will make the car fun to drive.

after awhile you will get bored of this though, as i am experiencing. this is where things become very, very expensive
