A bunch of questions about my 04 Pathfinder

[jroo]

Im new to the Pathfinder world. My brother passed away a few months ago and my parents gave me his truck after his estate and insurance were settled. I have been reading and trying to find out as much as I can about this before I posted. It seems there isnt much support for an 04 Path? A few questions to get me in the right direction. 1) I see a few rotor and pad upgrades, but does anyone make a true big brake kit for this truck? I want to go up in rim size but want to do brakes at the same time. 2) Are there any ECM/chip changes for this truck. I see things for older Paths and newer paths, but nothing for 04. 3) The only offroading this truck will see is going up the grass for a cookout or tailgate, so I am going to a 20" or 22". The tire sizes for both should stay at 45 series for 20" and 35 series for the 22? Last question guys. I saw a vortex supercharger for a 350Z. Has anyone tried to adapt anything for the z to fit our trucks yet? Not that I am going to do it, I just wanted to see if anyone tried anything.
