If you can do the 5S to 3S swap, then converting to a manual while you're at it will be a walk in the park and well worth it.

Yes, you will need to drill a hole for the clutch pedal and master cylinder, but that's easy when there isn't a motor in the way. You'll need new shift cables but again, easy. It's a small investment that will give you huge returns when it's all finished. I've had both and trust me, the auto just can't compare
