My order of modding:
With limited fund and experience, I went/plan to go with the easiest/cheapest first
1. Intake (K&N RU3530 + MAF adapter = $80)
2. Optimized Y pipe ($100)
3. Exhaust (I did it with 2 together. The price depends what exhaust you put on)
4. UIM/LIM rebuild
5. Professional detailing job
6. New tires with semi-new wheels I got for cheap
The following I haven't done, but have the parts already
BAT kit w/ Eibach springs
New Torson T2 LSD (may not even do it if I don't have a 3L plan any time soon)
I probably will do optimized Thottle Body
But like every body said, 3L may be the most impressive mod. Currently my reasonably-low-miled SVT engine still runs very strong so I probably will put off for a short time. And, if you have expericned local guys around you can save a lot on the labor. (THANKS Scott and Pete!)
