2001 GT Mod Question

[Craig K.]

A son of a really good friend of mine is getting ready to buy a 2001 GT next week (back up north).
The car is 50k miles, automatic.

They were questioning me for a mod list.
The dad will help a little with mod money, however the son will be doing most of it, so it will be done in stages.

Here is what I was thinking about:
1) 4.10 gears
2) Cat back
3) cold air intake and a plenum
4) Pullies
5) complete the exhuast (still have to have converters for Chicago area testing) but I was thinking headers and high flows.
6) custom tune

This car will need to last the boy atleast 5+ years, and will be his only car, so no power adders will happen, and no internal mods.

Figure this would be over about a 1-2 year process.

What do you mod guys think???
