....unfortunately it turned out that I had cracked a piston, at best case you have messed up the rings, at worst cracked piston(s).
My piston held together, and I ended up installing a pretty closely matched set of used pistons and new rings, because luckily the cylinder bore was not screwed up.
I would stop driving it immediately. What did you set the timing and boost to? Since it looks like you will have to pull the engine regardless, I'm sure you can get some used turbo pistons really cheap, or just do a nice econimical rebuild if you can do it all yourself. I didn't even change bearings in mine, we just put the rod bearings back in upside-down so the upper ones that were more worn from the compression stroke were in the cap, and the lesser lowers were in the rod. Runs like a champ now, we just had to take it easy for a while while the new rings broke in, we didn't even hone the block. The whole thing took a weekend and like $60 in rings, because we borrowed an engine lift.
Sorry for the (possibly) bad news, hope some good comes out of it!
Drew
