Ianetti Apex Seals

[Schtoo]

Had a quick look at the one and only mag I have here, which fortunately covers "oobaahooru" (overhaul) of engines.

The have an in depth interview with 6 builders.

Fujita makes no mention of ceramic seals.

Some curly haired guy\'s shop had no mention of them. Didn\'t work out who this was, till I looked at the characters, Amemiya...

Some shop called Top Fuel has a pic of 2 seals.

The pic shows a * 2 piece ceramic. Not sure on what the kanji (Japanese character) means, but I suspect it\'s a Mazda part. The other seal is a domestically made 2 piece ceramic seal (I can read that kanji!). The domestic seal\'s corner peice is much longer than anything else I have seen. Normal corner pieces are a triangle, this one looks like it is a square and a triangle just to give you an idea of the pieces size.

Also many pics of 3 piece seals and similar parts. Also shows some of the special tooling used to get the seals to size and stuff like that.

Surprised by Amemiya though. The curly haired guy is out on the street with a hose and a die grinder doing ports...

The other 3 builders are Pan speed, Revolution and Knight Sports.

Rebuilds from these guys range from Y220,000-550,000 for a standard rebuild. Plus extra for as wild as you want to go.

Interesting, but completely useless if you can\'t read Japanese. I can\'t read as much as I would like, but I can make out enough to know what\'s going on.

No mention of prices in this book, but I haven\'t been looking for ceramic apex seals either.

I have read that using ceramic 1 piece 3mm seal with used rotor housing can take up to 5,000 miles to break in properly and to start seeing sensible compression. Apparently when using the 1 piece 3mm ceramic seal on used housing a harder spring is used to get better sealing to help overcome this issue.
