P&P heads but thats $1,400. Air filter w/ MAF adapter, headers, true dual exhaust, struts and springs, tint, wheels/tires, SAF-C, custom chip. Not all performance but there's a ton of stuff you can "waste" money on. Oh get a Torsen or Quaife.
Torsen goes in the transmission and makes sure you don't break your stock trans. from anything. It helps a lot with traction off the line and in corners as well. Sort of like the "takes power from the wheels that slip to the wheels that grip" idea. Take your time and search for everything I talked about above. The forums have been around for a while so you should come up with a ton of info. on what to get and what not to get.
Of the mods I did to my 2.5, god rest her soul, the quiafe combined with the lightened flywheel was probably my most favorite mod I did. Gets that powa to the ground!
