Motor and trans are in, interior is half-assembled. We had one seat with a deployed airbag. That's been stitched back up. We replaced the airbags in both STi driver seats with the airbags from the Forester.
Add to the list of parts not usable from the 2.5X Forester - Radiator fans and shroud are not compatible without getting into modifying things pretty extensively and still having questions about the ratings of the parts. We're just going to grab some XT or STi parts.
The radiator dimensions (other than thickness), mount points and plumbing locations are the same between STi and Forester, but the NA Forester radiator is under-sized for our needs.
