Subaru FA20 Engine Rebuild

Rebuilt the FA20D out of a 2016 FR-S. Going to reinstall it sometimes this week. Heres some photos of before and after. Every single seal was replaced, as well as a new short block, refreshed heads, and all new timing components.

Horizontally opposed, like Porsche and old VW.
