Oops, I almost forget. One of the most important mods you need is an upgraded rear diff mount. SU makes them $175 and so does CPE $255 (rpm store). The stock rear diff mount is a very well known weak point, and is a must do. They break an axles snap even on a bone stock speed. The aftermarket ones I mentioned are bullet proof, and you can launch all day on them (slip the clutch, don't just dump it). Regardless if you launch or not, I HIGHLY recommend this mod. There is a thread on another forum dedicated just to "broken diff/axles" thread.
Just do a lot of research, and keeping asking q's and search some threads. I went like this:
1. SRI + TIP
2. TWM Stage 2 sts 2/ bushing, and all Redline synthetic tranny fluid + gear oil (my 1-2 shift was glitchy as hell and I couldn't stand it. This eliminated that completely.... car shifts like a dream. Have a vid if interested.
3. CBE
4. CPE rear diff mount, and SU rear motor mount
5. SU test pipe, Access Port, and hpfp (you'll need a hpfp using the AP), Denzo ITV-22 1 step-colder plugs (also need w/ AP)
6. CPE fmic + HKS bpv. The stock BPV works great. I couldn't use mine w/ the fmic, because there is no bpv flange (to mount on cold pipe) that is specific to the speed's stock bpv. I was holding 19 PSI all day on the stocker w/ no problems. the point is, you don't need to upgrade the stocker imho unless you decide to get an fmic.
7. Perrin ebcs
I'm waiting on a CPE fuel pump (don't buy the PTP internals... they F'd up my car). Finally, I have the following awaiting install when the hpfp arrives (been 6 weeks):
8. PTP intake mani spacer
9. Labonte Stage 2 w/m kit
I put the DP off earlier bc it's not a 'reversible' mod... I was under warranty until 2013/100K miles, but now that the warranty is pretty much useless, and ATP catted DP is next on the list. Then a pro-tune, and I'm done. I swear this time!! lol Maybe a BT and egw exhaust mani if the funds ever appear.
