I have a 99 maxima with 56,000 miles on it i want more power but im not sure if i want a turbo or a supercharger how much are each of these and which one is more reliable? and do i have to take out my a/c and reloacate my battary for this? thanks guys!

 

Cost is similar. Differences are installation difficulty and maximum power potential. S/C does not require removal of A/C or battery. Turbo might.

Read the stickies, search around. Good luck.

 

The Stillen SC kit is pretty much plug and play, as long as you don't get a pulley smaller than 3.25".

A turbo is going to require much more effort in installation and tuning, but the reward is substantially more torque than what the SC will produce for a given boost level.
