This is what I read about boring and sleeving a 1.8 to bump up the displacement to 2 liters. Not sure if they do 1.6 motors too though.

I don't believe I've ever seen an off-the-shelf piston larger than 79.5mm for the 1.6l engine, though either Wiseco or JE will custom-manufacture a piston to damn near any spec you could want.
I guess the big question would be why? Good 1.8l blocks are a dime a dozen, and there are plenty of lower-than-stock-CR pistons available for them.

I am a 1.6 purist and will fight for them!
Wiseco makes off the shelf .060 over pistons, 79.5mm bore
If you need bigger than that, you might as well get a built 1.8 or 2.0

I mentioned sleeving because at 81.5mm you will very likely be in the water jacket. But if you have it sleeved you can typically go much larger than the standard overbores because sleeves are thicker and will have a consistent thickness unlike a 20 year old cast block of rusty iron. And yes, it can be done and is a common procedure.

There is no way you'll be able to get an overbore that big without warping your cylinder walls, they will be way to thin, or like said above you'll be in the water jackets. If you want to go that big you might as well get a 1.8.
Sleeving is expensive, and not common practice on our motors due to them being iron. I am not sure what you're going to get out of it anyways, any of your goals and dreams can be done with .60 over like I have.

FULLY agree with these guys... Overbore too much and you will either break into water jackets or it will be so freakin thin that even street driving youde risk overheating the metal near the jackets to the point it will either warp or burn through completly, let alone be able to hold boost/power... Thats why instead of just boring out the 1.6 Mazda created the BP 1.8 block. They HAD to stretch it out a bit to get enough meat between the cylinders that problems wouldnt come up. Sleeving the block, while possible, I wouldnt reccomend just because of how much $$$$ would be involved. Get a BP and call it a day.
