I am renovating a PA engine, something fairly standard. The min bore size is already 58.52mm and the remaining liner is about 0.5mm thick, see image. Any advice on whether to continue to bore it out and get larger pistons or re-sleeve and go for original size? Is it wet or dry?

Hi,
By my reckoning the linered bore is now at 57 mm plus 60, that is the maximum it will do. If all looks well and not worn plus 60 pistons would be fine, if it is worn new sleeves snd back to standard is the way to go. The sleeves are supposed to be dry but yours would not be the first to have liners repairing damage.
Hope this helps,
Garry
