260 Rings$$$

I’d just bite the bullet and buy a set of the Gold Ti Nitrate rings. Nic bore 2.5s are getting harder to come by and hanging a piston in the bore at high RPM due to a cheap ring breaking or sticking will make a nice window in your block. Don’t ask how I know. I see Powers has them for $599, which is a lot, but a lot less than replacing/repairing your powerhead.

you may want to check with Dean at Wizard too, his pistons use merc rings. Is this what your talking about with a stuck piston in an expensive nik block? haha check out number 4!

John Marles has sets Chromoly rings that apparantly last just a long as gold rings and does not hurt the nic. He said he has seen no issues with them. $200 shipped for 12 rings. Probably Ti coated.

Thanks. Good to know. That guy really knows his sh!t, so if he says it works, I would take his advice.

That looks good to what I did to my first 260 years ago. It stuck the piston so hard that it broke the crank, the rod snapped and windowed the block so bad you could stand on one side and read a newspaper on the other!

These are the rings I have been referring to, they are black oxide coated.

I'm leaning towards staying with the gold rings. John said the black oxide rings would last 100 hours...does that mean they need to be replaced somewhere around 80-90?
I know the gold rings will go at least 120 hrs. It's worth the money to me for another 30-40 hours of life. Not to mention the cost of gaskets and seals to do a re-ring.
