Default Bolt On time

I've finally decided to indulge and get some bolt ons. I've made a basic list of items. I figured I'd post it and get feedback (if I'm going in the right direction, better products, etc). I'm not looking for crazy perfomance but a little extra power never hurt

1. CAI - BBK Cold Air Intake
2. MAF -
3. TB - BBK 70mm TB
4. Plenum - Stack Racing Plenum
5. Gears - Ford Racing 3.73s
6. Handheld Tuner - SCT SF3/X3 Power Flash Tuner
7. Underdrive Pulleys - Steeda Underdrive Pulleys
8. Other - Full PI Swap

PI Swap is listed last because of availability. I plan on making the first purchase soon (CAI, TB). Feedback is welcomed and appreciated.

Everyone has their own opinion, however I've been told that the money spent on a CAI is kind of wasted because the flow of the stock system is sufficient. So I just spent the money on a filter and left the plumbing alone.

I'd get a filter (or whole CAI kit, whatever you prefer) then the tuner. With lifetime free tunes, it wouldn't hurt to buy it early.

Personal preference here of course.

I would do #5 first. Gears will give you the best acceleration improvement for the money.
A tuner will be needed to recalibrate the speedometer with gears, so plan to do that at the same time. If you have an auto trans, you will notice a nice improvement in shifts with the new tune also.

The PI swap would be next on my list. That will help your car quite a bit and modding the non-PI motor is going to leave you very disappointed. The PI platform has a lot more potential than the non-PI.

The CAI, TB, etc should be a low priority vs gears and PI SWAP.

If smaller projects are your desire at this time, I would suggest thinking about a few suspension mods(FLSFC, LCA, springs, shocks) instead of CAI, TB etc. You will notice a lot more difference with suspension mods than those motor mods.

Enjoy the mods and don't be bashful about asking for feedback from those of us who have been where you are now.

while your swapping the heads, have them ported and throw some stage 1 or 2's in them. i would skip the maf ans cai personally and just remove the screen in the stock intake and drop in a filter

With the PI swap, should I do just the intake or full? I found heads and cams on ebay for $450 shipped. Came of a '00 GT with 90k. Good/bad?

you want 02+ heads. 99-01 has a few different bolts. 02+ will make it easier for the full swap, not just the intake.

Agree with the two posts above.
If possible, dropping a pair of cams in the PI heads would be the way to go. Much bigger power gains that way.

If you buy heads. etc from someone you don't know, be sure to get an agreement that you can return them within a week if they turn out to have any issues. Most guys are honest, but there also could be a reason that someone has removed these parts.

When you do gears most guys on here will tell you to get 4.10's.Since you have a 96 a handheld tuner will not help you with your speedometer.You'll need a speedcal for that if you go above 3.73's.If you had a 99 and up the tuner would help.These guys are right,do the full pi swap with after market cams.I think kukzy is at almost 300rwhp with his set up.That's really really good imo.If you do the pi swap you'll want to get a dyno tune and you would need a handheld tuner for that.
