I cant say whats acceptable and unacceptable for a rebuild as I havent done it, but it says it can repair wear up to the steel liner.

I'll throw the link up with of the .pdf with all the info. Just jump to page 3.

It's true, doesnt seem very cost effective at the moment but someday used housings are gonna get real expensive

 

Rx-7 Specialties in Calgary can cermet coat old housings, though they want just under $700 to do it.

 

IIRC its 2mm of chrome flaking in from each edge.

 

So what you guys are saying is that nowhere in the world do they cast rotor housings?....sorry I'm a bred V8 guy....I do not posses teh full rowtawree nawledge

 

thats what we are saying. new 12A housings, like the dinosaurs, are extinct.

 

We should break into Mazda headquarters....steal the housings diagrams...and then force someone to make duplicates....or else...or else....

Or else we drop a 4 cyl. Vtak in their 7 as punishment

 

There was a fire at Mazda's Hiroshima casting plant a few years back. After that they concentrated on making only housings for the RX8. I don't know if the equipment for the earlier housings was destroyed or not but I was left with that impression.

 

 

SHOWOFF ........... **** off

 

Yeah, that's approaching cruel, Sarge. /crai

 

the rotary is pretty unique, unlike just about every other engine, mazda actually makes everything except the seals in house.

seals are made in germany, right next to F1 pistons
