I'd go for the EXP or '89 Escort engine. Those are the closest to what you've got. Also, if I just remembered correctly the 2.0 block has a different bell housing bolt pattern since it was used with a different transaxle. The 2nd gen engine is not what you want since it was rated at 88 hp. The head is the biggest problem. If that '89 Escort engine is from a vin 9 car, then it's CFI, and basically the same as the 2nd gen, which would make the EXP engine the best choice. Specs for that '82 are as follows: 8.8:1 compression ratio, 70 hp @ 4600 and 89 torque @ 3000. Not very strong, but there is plenty of room for improvement. I wouldn't go for the Mexican, either, as that's a different animal, What kind of prices are on those early complete engines?
