I'm building all motor poorman type R and have P73 honda pistons oversized .75 over. I know I know before you start saying there is no such a thing from honda, I will say yes it's and I have it. I have done my home work on it. My problem is, I can't get Honda piston rings that is .75 over. Anyone know where I can get these rings. I called the dealer and the customer service guy told me this is the place to get answers so I hope you guys won't let me down.

Piston ring measurements are:

ring 1: 1.0mm
ring 2: 1.2mm
ring 3: 2.8mm
Pistone dia: 3.270in
