I want to get a wiseco piston for my blaster. My question is that on their site they have a big selection. I want to just get a replacement. Is it correct that the replacement size is 66.00mm? Also if I wanted to buy something like a 66.25mm piston, would I need to buy a bigger cylinder?

Thanks, sorry to be such a noob
 
get the bigger size that you mentioned and have the cylinder bored and honed it will be like putting a new piston into a wore out cylinder if you dont
