I am curious if anyone has used nippon type s h22 pistons with the stock h22 sleeves? I was looking at a set of oem honda's but they cost a little more and dont come with rings. here is a link to a set on ebay http://cgi.ebay.com/ebaymotors/JDM-P...3A1|240%3A1318

 

The block i have now is sleeved but ive run them in stock blocks and i have not had any problems but you can get stock ones for the same price with out rings but you can get the rod bearings,main bearings and rings for like eighty shipped so its what ever you want . I think i still got the stock set that came out of my motor i just bought new ones before i tore it down but it ended up being a balance shaft bearing so the pistons were fine.

 

take a look at the dimensions of the oversized pistons and compare that to the service limit of the block. now would you trust them?
