I have the money to start heavily modding my car and was wondering what you all think of the following setup. I have a year left on my warranty so I plan on staying all motor for atleast the year maybe for ever. If I do go FI it will be comptech w/ aftercooler.

Apexi Single n1 cat back exhaust Installed
Comptech CAI
Comptech Reinforced Differential
Rick's 4.77 gears
AEM EMS Standalone
Clutch Setup after my stock goes out, suggestions?
Toda or Comptech Header
Wieght Reductions
Alaniz head work?

What would you think all that would net me. I know it will be alot of money but thats not an issue I just figure if I do go FI it would be nice do already have that stuff done minus CAI. I will switch to 4.57 final drive for FI if I do. I plan on having shawn (ultimate lurker) do the tuning.

 

I'd say that's a pretty good setup considering the fact that you aren't sure if you want to stay NA or go FI. Most of those mods would be beneficial to either setup. My only comment would be this:
Before you get your headwork done, you need to decide whether you're going NA or FI, as Alaniz will need to know this so he can design the flow characteristics of the head accordingly.

Also, when you do the clutch, you may want to consider a lightweight flywheel.

With all of those mods (and the head work targetted for an NA application), I'd say you'd probably gain 20-30rwhp (peak). However, if tuned properly, you should get some really noticeable gains in the mid-range (5-7k rpm).
