Hey. So I took my block to the machine shop and they said i need .020" over sized pistons, which is .50 in metric. The problem is, I dont think I can find anyplace that sells oem honda pistons at that size. So Im not really sure what my options are. Im not going turbo so I dont need low comp. pistons, and Im not using race gas so I dont want high comp pistons, and I dont need forged for sure. Any ideas or sites to visit would be great. Thanks.

Anyone have an idea?

 

So this is what I found from Wiseco. Im pretty sure they are forged. But the compression ratio is rated 9.3-9.8, so im not sure exactly what that would be with an lsvtec set up. But the next compression ratio up is in the 11's. So I think that would bump it up too much. I still want to find OEM ones, but have had no luck searching. Im guessing they dont make them .50 over sized.
