ill tell you what i see, in japan where our cars come from you really dont see too many s/ced 4banners they are mostly turbo powered if theyre using forced induction. what you do see superchargers on are american muscle cars which have tons of torque to spare to drive a sc. a good turbo setup aimed at making around 250whp isnt going to cost that much more than a jr sc setup which bairly makes 200whp, and it definately will cost less than the vortech setup with an aftercooler and bov.

as far as reliability goes, most turbo engines end up paper weights cause of one of two reasons, either the owner felt doing oil changes was an option or they decided to turn the boost higher than their mechanic told them to. avoid this and you will have a very reliable turbo car.
