i am lookin at a late 80s or early 90s 2.3 fuel injected mustang.is there any definite way to tell what year it is without running v i n numbers.i have plans to put a 428 cobra jet in it .also did they come with the 8.8 rear end or another one.
non-airbag car = 87-89
airbag car = 90-93
25 years dash emblem = 89 or 90 model year
dash emblem without 25 years = 90-93 model year
large SN95 style dome light = 92-93
Start with that, tell is what you find and then we can give you more clues.
A few other ways to check: The door tag will show month/year of manufacture. Check the ignition coil cover for the emissions decal. That will show the model year. Check the glovebox for the original owners manual and see what year it's for.
Some stuff I have found with the 2.3L that may help identify the year:
87-89 got an HR980 small steel body A/C compressor. 90-93 got a 10P15C aluminum body compressor with top mount inlets and outlets.
91 (90 california)-93 cars are mass-air and have coil packs, 8 spark plugs, no distributor, and a large mass-air sensor in the intake tube.
