eh.. a turbo on an xterras engine would work in theory- but just not practical. even a small turbo would boost too high in the rpms to do you any good offroad.. even onroad the top end would be crap due to how heavy the X is.. by the time you reached full boost you'd be at your shift point.. which is pointless. best bet on these motors is a supercharger- power all the time.

but then again.. me and turbos dont seem to be getting along lately since ive blow out my 2nd bottom end in the past 3 months.. something tells me i should turn the boost down
