I'm planning on performing an engine swap (Ford 5.0L H.O.) on my '93 Miata. 
The California Air Rersources Board (CARB) requirements on engine swaps dictate that the engine and emission controls for the swapped engines must meet the year of the vehicle or newer.
I'd rather use an earlier 5.0 H.O. ('89) but don't know the differences from year to year on emmissions equipment. Can anyone direct me to a site where I might get yr-to-yr emissions equipment changes for 89-93 5.0L H.O. Mustangs?
