Physically, the answer is yes. the 1990 and the 1991 comanche, however have different engine management systems. the 90 is supposed to have had the Renix fuel injection system and the 91 switched to the Chrysler system. You would need to make sure the sensors on the engine were switched to match the vehicle. Also, any 4.0L HO from '91-up from the XJ, TJ, ZJ and even WJ vehicles should be a bolt in as long as you match the sensors. Later model engines are said to have stouter support ribbing on the blocks.

No
The 1991 is the 4th generation Accord. Most parts on a 1990 to 1993 are interchangeable.
Yes if it is a 4.0.
Altrincham Interchange ended in 1991.
yes
1990 is ka24e, single overhead cam, 1991 is ka24de, dual overhead cam.
Interchange would only be possible if you had a ENTIRE donor car, harness, transmission, axles ,mounts.etc
The motor in a 1991 Accord is interchangeable with the engine in a 1992 Accord. They are only slightly different but will still interchange with no problems.
Workgroup for Electronic Data Interchange was created in 1991.
