Okay, here's the deal. I just bought a 2002 Sentra GXE close to a month and a half ago. Already I've bought a ingen tech. cold air intake to it and plan on doing lots of other things to it. Well, to what I have found here on the net, there isn't much I can do. I've found some body kits and some lowering springs and what-not, but have yet to find anything really performance wise (i.e. turbo for the future). I would like to know if anyone has a place I could look at for mods or anything besides a sticker that says Nopi on it. Just let me know b/c I'm seriously in deparate need of some more power (it's hard to pass people on the interstate with a 1.8 lol).
