If it's an SVO - 205 HP, in '85.5 they were rated at 210, but in '86 Ford issued more restrictive mufflers, downgrading it to 205. If it's a TurboCoupe - someone is much more knowledgable than I in that depertment.
Only the 85.5 had 205 hp, the 86 had 200hp Take a look here http://fordturbo.com/mainframe.html under TC,SVO, Merkur and XR7 Facts they list all the chages from over the years. Dan
