its about $6500 parts for a good system, and 11 hours labor if you do it yourself and have proper tools. you will gain a good 100 HP at the wheels easy. 0-60 will be under 5s. if you are installing a supercharger it would be "smart" to change all the ignition coils and spark plugs, and engine performance sensors (O2, air intake temp, crank position, TPS, MAF) but not required. also do valve cover gaskets, and make damn sure your oil pump is in proper working order, and you have new trans and engine mounts.
since you have a manual, i would only worry about the clutch, but you should be ok drivetrain wise....
