If I increased the “texture” of my Nikasil cylinders, I would want to check them for surface roughness with a profile meter. Nikasil is so hard that if you get it wrong and have the cylinders too rough, the rings wear out very quickly and the cylinders stay rough. Not like typical cast iron where the cylinders start rough and smooth out as the new rings seat.
