I have a turbo on my 2.1 from an old subie...although the van has very few
miles on it with the mod, due to the original turbo being bad shortly after
I installed it. Tried an Audi S6 turbo but it didn't produce the right
boost, so back to a new  subie IHI unit.
I had Boston Bob do big valve heads and a cam with more Exh lift and ration
rockers and bobs stronger rods.
Modeled it after the Robert Lilley Mods of a few yers ago..
Love the way it runs..feels like a 2.2 subie as far as power goes with the 5
psi boost...some prototype pics on the link at the bottom of my home page.
