There's write ups that explain how to use jdm or other obd1 motors in our obd2 cars , one of which is popular where you splice 4 different wires on pcm plug c to jump signal and eliminate the crank sensor. Unfortunately for luders, the tdc sensor is not in the distributor, so making the splices, simply jumps one dead wire to another dead wire.

The fix:

Simply swap the oil pump ober to your new block, retain all crank snout sprockets from odb2 motor, bolt in the two sensors, and away you go.

Never saw anywhere online where the prelude issue was specifically addressed so here it is.

 

This has been discussed many times and is in a bunch of threads on this forum. Just have to search and you will find this.
