There's a pretty good supercharged forum on ka-t.org if you guys wanna learn more about the whole dealio.
The main things to know is that after about 250hp, the m62 from the Frontier/Xterra is out of its efficiency range, and only produces more heat. Right up at 250hp, most people are running water/meth injection to cool down the intake temps as it is, anyway.
The down side of this setup is you're pretty limited to the m62 or the m90 (which takes a bit more work to fit on the header-size of the engine).
Still... instant boost, and the s/c plays off the strengths of the KA really well, too!
