A Honda bud did this for drag racing because of the closer gear ratio.

It served him well with a short throw shifter for faster shifting, but he had other mods that work together.

Just get one that comes with an appropriate transmission.
Most likely, the ECU that comes with it is mapped and tuned for the ph16 transmission.
