What is the largest/safest bore size

[msbweiland]

What is the largest bore size you can go on a turbo 2.0? I have a block with a BIG ding in the cw. I would assume it'll be over .040.

I think wiseco makes some .060/86.5mm pistons. Not sure if this is recommended but it makes it an option.

Some people have overbored to .080

I talked to my machinist, he suggested to just sleeve the one hole. He has done it many times before, including my Cummins w/560k. Worked out well before and saves me the BS of finding another block.
When we're done it'll be .020 over.
