what are the best pistons

[TEEVILLY]

Just wondering what everyone thinks the best pistons to run are. I am needing to do a top end job and was just wondering what brand I should go with.

oem or pro x pistons...wiseco's are good also.

where would you get oem pistons for a 657x engine

OEM are Original Equipped Manufacturer so any Seadoo dealer or rotax dealer.

I would stay away from hypereutectic pistons. Wissco started to offer these pistons and they knock bad till warmed up. They are light weight but full of holes. They add extra silicon to the mix to get more bubbles in the casting. If these bubbles are near the ring lands the ring lands will pop off just from a bit of detnation. OEM pistons are best as of yet BUT Doo did try to run a bunch of these pistons OEM in their sleds and popped many many pistons under warranty.
