![]() I'm going to step up and say you have the rarest rotary car on this forum. I'd love to see pics! Have you looked into ceramic seals?? I've read that the early NSU rotaries suffer from more wear and tear than the Mazda rotaries (rebuilds aren't uncommon at 50K miles) and ceramic seals (apex and side seals) might help with the longevity of the NSU rotary.

Carbon seals will work great, and they'll last 50K miles, which is plenty for me. However, I've been told they can break if or when (in the case of my car) backfires. Steel seals are stronger and work well with the cermet, but they take forever to break in, and develop less compression, at least in the NSU motor. |

The only problem I see is the size difference in rotors. He's made the seals for 12A and 13B motors so far and I don't know ANYTHING about the NSU and it's dimensions.

That does sound good actually. This engine makes 50 hp, but I like the fact that they don't damage the housing. I'm going to try my steel Ro80 seals in my cermet housing first, they may just do the trick. But if they don't, I will definately give ceramic a look-see.

Hey all
![]() Not up to speed on NSU stuff. This is a 1 rotor right? I think they used a 6mm seal just shorter than 12A? The best option, if considering ceramic seals, is to find other owners of like engines to keep the cost down. If you are using cermet housings you will want ceramics.......cermet loves ceramics ![]() Cermet housings with 80,000 miles on NRS 3mm 2pc: ![]() ![]() ![]() ![]() ![]()
