Hey man how you doing?
Im still building my rb25det neo. I bought a set of piston rings from you a few months back. Now I'm at the point to install the internals, I start filling my rings to specs, everything seem to be fine. My questions is! I have r33 rings and neo pistons. can I use r33 rings or do I need to buy r34 rb25det rings. I know neo has a different part number than r33 rb25.
If I need to use new rings for my neo do you have them? How much?

Thanks!!
