In addition to the supercharger (which includes the supercharger, inlet manifold,discharge manifold, supercharger shaft, housing and pulley) here's the list.
Fuel system booster
11/32" x 16" Line (to PVC)
11/32" x 11" Line and coupler(to vacuum tree)
Vacuum line assembly
New drive belt (same size as stock)
Front Supercharger support bracket, idler & hardware
Manifold bolts
Lower intake manifold gasket
EGR plate gasket
TB gasket & bolts
Fuel sysytem Booster lines (2) and Safety clips
Thermostat Housing, Gasket and bolts
Radiator Hose sleeve, clamps (2) & loom clamp
Coil bracket
Coil wire
T-handle wrench
That pretty well sums it up. Be aware that if you have a GT40 intake the standard KB will not fit. Since you have 24 lb injectors you may not need the Fuel system booster (it's designed to work with the stock 19 lb injectors. At WOT the booster shuts off the return line flow which increases fuel flow to the injectors). Confirm with KB.
