i throw my bias around, but i like the supercharger. if you want your ranger to be like the "lightning" (the come stock with the S/C) thats just my thought..if i had the money, i would swap the 5.4 with S/C into my ranger...like those dudes already did...thats a lightning bolt for you..
i have the whole lightning setup ontop of my 4.0 v6..yaa its expensive as someone said, soo the 2.3 might be the best bet on this one.
if you really want a "lightning'ed" ranger, i would stay with the lightning supercharger, otherwise, what about it will connect it to the lightning?
