I was on ebay and came across some nippon racing pistons, they're suppose to be made of a different material from the factory ones. They're also made in japan( thats what the box says on it). Supposedly they're a better alternative to the stock ones. If anyone knows of any reviews about them, inform me about them. The guys ebay store is guit-guit performance.

thanx

 

Their rings are real good. But I heard their pistons suck.

 

i have heard bad things about those pistons as well.
