i'm a big fan of supercharging as well - instant power w/ no lag. not a big fan of how they did engine mgmt in most of those kits, however - 7th injector and piggyback computer - can't help but think there's too much room for error in something like that and, combined with a weak engine (as opposed to say the same application on a 964/993) perhaps one of the reasons why supercharger kits have a bad rap for failures - a few too many lean conditions in a weak engine resulting in holed pistons.
most of the turbo kits have gone to larger injectors and custom tunes of the existing computer, so should run safer (within the bounds of the relatively limited timing adjustment allowed by the computer, and the lean conditions caused by the lack of diverter in most cases) but i think the turbo kit makers still struggle with the bad rap FI of these engines was given in the early years by the supercharger kits.
having said that, if you have a source for a used superchager kit for $2,500 - lemme know - imagine a twin-charged boxster!
