Somebody who knows more would have to gauge the bore scratches. They may come out with a light hone. Otherwise cylinders aren't that expensive.
Clean up the races, Replace the bearings and move on.
Unless a short block is stupid cheap, that should be the cheapest way to go and should last 75-125% as long as any other rebuilt short block.  |
I'm not rebuilding a $1000 turbo that's too small for what I'm doing anyway.
If I hone the cylinders more than .05mm the car will have a bunch of blow-by unless I can get some oversized rings. And even then, there will be a bunch of wobble to the pistons. I'll end up with pretty bad compression, which may or may not be a big deal. However, "cylinders are not that expensive" is not at all true. Sleeving the block will likely cost more than a new shortblock.
Cleaning up the races and replacing the bearings isn't simple. It means getting the crank cut on all 4 cylinder races, getting custom sized bearings, and potentially replacing all the rods. At that cost, paying the $1500 for a new crank is probably cheaper.
A shortblock with forged pistons for $2500 sounds damn cheap if we're talking $2000 for sleeves and $1500 for a crank, and $200 for a rod. Plus $200 for bearings. Then paying to assemble it all.
