Oh and I do want to go with the 225mm clutch so 83 vs. 84-85.

83-91 non turbo cars all use a 225 clutch. If you don't care about the "beehive" oil cooler on the 83-85 12A, that's the best years. You can always change the "beehive" out for a FMOC.

83-85 12A engines are all the same. All have the lighter rotors, and all use the 225mm clutch.
This is partly why the 83 is sometimes refered to as a "S 2.5" The body is S2, engine is S3.
