motor swap and complications with 93 eagle summit

You most likely can swap the intake plenum. Since the 96 appears to have an external crank angle sensor and the 93 has the CKP (crank) and CMP (cam) sensors inside the distributor, the simplest solution would appear to be to use the orginal distributor. You should realise that the 93 has one O2 sensor and the 94/95 models have two. The 96 probably requires two as well. Be aware that the O2 sensors are outrageously expensive. One (non-OEM) has a list of $321 last time I checked. You would need the 96 ECU to go with it all.

All this comes back to replacing the 96 intake and distributor systems (if possible) on to the 96 engine core. If swapping the distributor is possible (it may not be) you are faced with getting schematics for both engines, and adjusting the 93 wiring to 96 specs. Its not difficult, just tedious, and the second O2 sensor has to be fitted after the cat.
