the std breaks are not too bad unless ur going on th etrack. Just get some new fluid and some decent pads initailly.
ECU has to be up higher on the list...unless ur doing a re-map who cant really do shit witht he stock ecu.
1. Zorst, turbo back
2. ecu + cheep boost controller. $22 ftw initially, nice EBC later to hold boost better.
3. hi-flo or equiv turbo + fmic - at the same time. Will need a new AFM to run the bigger numbers and either a pod or new intake pipe for the stock box.
5. suspension. shocks, springs, sway bars, pineapples - do this all at once and get it set right.
if u wanna run to 250, then 1-3 is definate. If you wanna be able to drive it fast then 1-4 is a must.
Then you will find ur coil packs and plugs are crap. And buy new ones - another $650
Clutch will not last - $1k-2k
GB and Diff should be fine.
You might like some nice wheels...always looks good.
