The FE-DOHC is the 16 valve DOHC variant of the FE. Commonly called the FE3 because of its head castings, it was used in some 626s from Europe, New Zealand and Japan; but not the U.S. or Australia. After the GD platform stopped production in 1992, FE-DOHCs continued production until the end of the GV wagon in 1997. The FE-DOHC was also produced under license by Kia for the 1995+ Kia Sportage.
The FE-DOHC shares the same dimensions as the original FE-SOHC, including the square 86mm bore x stroke and it has an ideal 1.74 rod/stroke ratio. The FE-DOHC is usually identified by a gold coloured cam cover, however not always. There were at least five different FE-DOHC engines available with various compression ratio, camshaft and ECU tuning combinations however none were fitted with a turbocharger from the factory.[WIKI]
