What Piston Size for .050 Over Bore?
Well everyone,Like the Title says.
The Mechanic that is Building My Block
Just told Me one of the Cylinders was no good
and that it had to get Bored out,I asked him
What Size Piston's we would need after doing a ".05 Over Bore"
But he doesn't know it by Millimeter.
The Block is a B16A2 and At stock Bore its 81mm.
So What Size Pistons would I need Now?
I'd Greatly Appreciate any Help or light you could shed
on this
Thanks

So 81.5mm if its .020 over?
well when the Block was pulled
out it sat at my brother house outside in the rain
Trust me I know.
So there was a bad compression on one of the cylinders due
to the water getting to it.
However What would I need for ".050"?

.050" would be a custom size.People often mix up their mm and inches when they talk about import piston and bearing sizes.Import piston sizes usually are available every .25mm (.25mm equals .010").If it's just some surface rust without deep pitting than a 81.5mm (.020") piston should clean up the cylinders.
