any good forced induction build will require all the internals of a n/a motor build... just different individual parts designed for boost. unless you are talking about just slapping a turbo kit onto your car with no supporting mods?

the only big thing i suggest, which might not be a big deal because they seem to hold most of their value in resale, is deciding what you want to do before you even start buying bolt on mods. it would make no sense to drop any coin into things like a lid or long tubes, just to have to take them back off if you decide to go turbo.
