the kit complete needs the s-tube for inatake, inatake mani,eaton m42, snout pulley,alt bracket with 2 pullies, jackson racing fmu(but dont use it), some superchargers for d16 vtec 96 and up need a crank pulley becasue they offset the belt for fitment on ek models. and a new belt. simple to install too. some even have a water/meth already tapped
they are good for 160whp stock boost 210 with a hair dryer 20psi and meth. the charger is too small imo even for a dseries. but its fun and great for a dd setup stay out of boost 40mpg in boost 30mpg. way better than new crz
