on these forums most of the time everyone will tell you to forget about superchargers and go with a turbo. they are right. you will see better torque curves and jsut more torque from the turbo (unless you plan on launching at 2k). if you want to supercharge, go ahead. dont let everyone tell you what to do with YOUR car, just make sure you do a lot of research before hand.
im gonna have to disagree with nissanfanatic about the efficiency of supers and turbos being the same. the supercharger will heat up the air more than a turbo and teh turbo can be intercooled. i dont know if the jackson unit is a centrifugal blower but if it is not then you wont be able to intercool, but if it is then the compressor might be as efficient as a turbo. dont forget that you will be using some of your already meager 107 ft/lbs to turn that supercharger so you might not get the response you want out of that unit. i personally am not a fan of belt driven blowers on any engine but especially not on little ones.
