I am replacing the H23a1 in my 92 Prelude. While searching for the motor someone told me that I could put the H23a4 in because they are basically the same. What kind of issues do I need to prepare for if I do this?

Again just like the two top threads, just use the long block and transfer over the intake manifold, exhaust manifold and all sensors.

And the check to see if the engine mounts are the same, some times different regions had slightly different mounts.
