Sprintex Supercharger system for Jeep 4.0L I-6 engines. The Sprintex Supercharger system is made to produce reliable torque and boost right off of idle and throughout the RPM range. These systems are made with the same emphases on reliability, longevity, and torque as other Sprintex equipped systems. These systems run very well on 91 octane gas when set at 6-7psi of boost. The colder operating and discharge temperature of the S5-210 means you don't need an intercooler. We have successfully doubled the available torque in the 1500-2000rpm range. 275hp and 300ft/lb. at the crank are delivered with lagless boost and crisp throttle response.

I was looking at the Sprintex site or someplace selliing a Sprintex kit for the 4.0L.  It looked like the kits for the 4.0L were going for $4,000, I guess in Australian Dollars.  Given the exchange rate, that's probably pretty close to what it would cost here.  Of course, if you apparently don't need an intercooler, that might save you some time/money.
