@NINJA some work in progress...

@SpookDog Taiwanese manufacturing often as good as found in Japan - in my experience. There is little evidence to support hard anodising of piston crowns when the piston is manufactured well in the 1st place. PVD coatings can be great, but unless designed in, and included in your bore finish & clearance allowances, a waste of time/money. It's very, very often just a sales gimmick as properly useful PVD coating is not cheap...
