Nutzurchin - a very good seller here on h-t. vouch thread - (https://honda-tech.com/zerothread?id=967673) is offering to sell me some pistons and new wiseco rings. He is unsure of the brand. He said his machine shop checked them to be 9:1 in a Z6 standard bore. He has no pictures. He says they look like any other forged piston on the market. The machine shop was not able to determine a brand. My question: Are there any high quality forged pistons out there that do not have any stamp to determine what brand they are?

 

did he check underside of the piston?

 

yes there is nothing there... i have been told CP and maybe wiseco do not have stamps

 

Im 95% sure my cps had stamps.

 

extreme power outers here on h-t said that they do not...

 

i just looked at my cp's and they DO have stamps on the bottom.

 

thats weird that they would say that then, strange strange strange

 

Mine say them as well....

 

I've had two diff sets of CP's and both had stamps on the bottom.

 

my CP's had stamps on the bottom

 

thanks for the replys guys... guess they're definitely not CP's - does anyone have wiseco's? stamped or no? Pics look like no...
- also would a ring made by wiseco for a certain bore fit a wiseco piston and maybe not a SRP or CP or JE or Arais?
