I am still interested in an answer to the question. How big pistons can you get into a sleeved 968?

Why not. To weld the outside of the block is easy. The cylinder lacks a small part in the lower end were there are little forces. I'll then fill up with concrete to support the sleeves.

Bengt, I would think many times about using that block by welding it. Anytime you have that size of a hole, in a cast aluminum with high slicone content, and in a block in which all parts contribute to stiffness and therefore to structural integrity, and because when you weld you rarely ever get the same strength and resistance to cracking that you had with the original it would not be the route I would take. I would get some opinions from someone who has actually welded up a 951 block and who knows metallurgy well enough to give you a knowlegeable answer.

I have done some welding of this type before which will help.
Looking at where the damage is located I am quite convinced that the strength is not affected by the hole. I could probably just put some plastic in the hole. The danger, I believe, is that when welding, the heat induced tensions may warp the alignment of the bearings.
I will not weld the bottom part of the cylinder since I believe the sleeves will be enough. There is really nothing to loose here. I do not think there is any risk of cracking that will appear at a later stage.
I'll post the results, successful or not, when I have tested. I am in no hurry since I have a brand new block to start with.
