Okay so your budget is $5k.
You would want (as a good all-round platform):
-Revert back to stock
BOV (better for you in the long run).
-Downpipe
-*edit* Fuel Pump
-Tune (Ecutek/Verso....use the search button for more info)
-Slotted rotors
-Better pads
-Beter brake fluid
-Stiffer springs
-Bigger swaybar/s
Then you'd have more grunt as you want (specifically, a lot more torque). As Kato said, no point upping the power and then relying on stock brakes + suspension to keep you away from trees/poles/old people
.
If you aren't giggling like a school girl from those mods, save up some more $$$ get a VF34/P20 or a TD05/20G, set of injectors if required and a retune. Giggidy
My 2c.
Happy Modding.
