Yeah, like he said, you don't need an intercooler or a blow off valve. Some have complained that the engine bay will get kinda hot, or the supercharger itself will, but as long as you have a competent fan (ie. even OEM, and it works), you have nothing to worry about. The boost guage, the oil cooler, all that is second to the JR MAP sensor. It'll run you about $150 (cheapest I've seen, you might find it for less), which I would recommend you buy WITH the JRSC. You posted because you were worried about internals getting damaged, well, you only need to worry about it if detonation occurs, and that might at lower RPMS if you run the OEM MAP sensor. So, buy the JRSC, and get the MAP sensor along with it. I envy you ... if only one was made for my 94 H23A.
