I dont' have a digital camera right now so I can't show you my Xterra. I haven't DYNO tested my truck yet, but I can feel and see the difference in acceleration since I got the supercharger along with the other mods. All my mods are emissions friendly, I know cause I've recently taken a smog test and passed. As far as my modified hood, I don't think you have to modify a 2002 and up yr models of the Xterra for the Supercharger to fit. Since my 2000 Xterra has a flatter hood that the newer 2001 and up models. I think the 2002+ models have a slightly raised hood and the installer said I just need an inch or two of clearance space. The Alpine supercharger with installation only cost me $1500. This is way below their suggested pricing ($2700) 'cause supposedly mine was their first 2000 Xterra model to have a supercharger installed.
