The engine should not be a problem if the sensors/system for the 96 is reused.

There monitors would become ready only after certain conditions are met and these are monitored after start stop driving conditions when no faults are recorded and system is working correctly.

Try a 40 minutes test drive under the following conditions. The time does not really matter, just an approximate period would do.
While doing test, avoid abrupt accelerations and do not shift to neutral when slowing down.
15 minutes on the highway, constant and medium speed driving.
10 minutes in city driving.
10 minutes highway driving.
Recheck monitors.
Repeat test drive if necessary.

Btw do not disconnect battery not perform any resettings of PCM to enable the monitors to be ready.
