I got info from Kennedy engineering (805) 272-1147 and they have a nice
table and information on the various Subaru engines you could place in a
Vanagon. Since I have not seen the info on the group - I thought I'd
duplicate it here for those interested:

According to KEP

KEP does not have the exhaust adapter for the turbo.  There is one person putting in 
the 2.5 now and feeding back change information for incorporation by KEP.

About thirty 2.2's have been done so far.

They have some completed on their shop vehicle (I don't remmber how many) and love it.
Over 18000 miles done.

This mod is now smog certified for California if you use their exhaust system.

The big differences in kit cost are if you buy their radiator, starter (recommended),
and muffler/cat.
