I prefer 3/32' wall sleeves unless there's a hole in the cylinder wall. Then I use the 1/8 wall sleeve for more support for the piston with nothing behind the sleeve. It's necessary to bore the hole about 1/4" oversize, less a few thousandths for a press fit, to install a 1/8" wall sleeve- - - -at least for the 200 or so I've done in the past 50-something years. I used to buy my competitors' "worn out" racing engine blocks for pennies on the dollar, install 8 sleeves as a training project for my students, and outrun those guys the following season with their own junk. Some of them never figured out what I was doing.
