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

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.

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
