I just did this to my buddys civic.
Use a rigid stone hone not a flex ball hone. I used wd40 to lube the cylinders while I honed them out.
500-800 rpms...Fast speeds can take off to much material and instead of a hone job, youll end up with a bore job.
20-45 seconds is too much imo. After all the research I did I decided to hone for 10-15 seconds for each cylinder,
Dont try and remove all the scratches in the cylinder. Just give the rings a good surface to bite into.
Def. wash with soap and water. Wash it several times extremely well.
After about 20 miles of break-in, the compression is so good, I can barely rotate the engine by hand with the plugs in. This was a stock 2000 civic btw..
Good luck and practice on an extra block before you do the real thing!
