sad to say but i think rebuilds are going to get more expensive...
was looking at my stock of parts, craigslist, ebay, for sale section here.... TII irons are becoming scarce to the point that used might not be an option soon, and it is only a matter of time before new will also not be an option as mazda has been selling off all their added warehoused inventory for anything pre RX8.
what it basically means is jspec cores, the good ones will soon be depleted as well as many other sources for the internals. the rotors also are very scarce.
i'm sure there's some people hoarding parts but even that is a last ditch to hold off the inevitable.
housings can be resurfaced to an extent, iron seal walls repaired/supplemented, rotor seal slots milled but it seems the parts are just disappearing lately.
this is mainly focused at original turbo engines, high compression rotors can be used and are not all that rare yet, but i can hardly even find a turboII shell of a motor to build up for those who want them anymore.
soon you might not have an option but a 6 port high compression turbo motor.

i guess i need to get off my butt and take a sweat rag and go pull some n/a motors before they get crushed.

I think I messed up the multi-qoute but anyways. The tub is thin. same as the rest of the rotor. I'm pretty sure one can't machine a turbo dish into an S5 NA rotor. I've sawed a junk one in half and welded on one just to see. I don't think it's possible.

The problem is really figuring out how to copy mazdas exact procedure for manufacturing them, they spent millions on R&D it wont be so easy to just manufacture by some company that just has a rotor they are trying to copy. If you look at the evolution of the rotary we may go back to the dark age of the chatter mark while they figure this **** out.

Meh, If Mazda drops the ball Ill just get one of those engines from a certian company that was just too big to fail.
Ever since I realized Racing Beat built the engine for the Furai instead of mazda proper Ive lost a lot of faith in mazdas comitment to further development.

So is it advised that I buy a personal stash from Mazda now to hold me over the rest of my FC driving life? I think I would need rotors housings and plates for 2 turbo engines. 1 set for and N/A engine. That should do me for the next 50 years.

Smells like 2 stroke.
It pisses me off that it's still possible to buy a GM iron 350ci engine from GM, but Mazda is phasing out everything before the Renesis. What the hell? It's like hell on earth! The 350 has been around in one form or another since 12A times!

that 350 probably fits over a dozen applications, our rotary engine only fits one car which is long discontinued and has a negative rep to those who don't know much about them. I think if this becomes a problem in the future, than you either baby your rotary, or turn to swap.
Im thinking about getting a 80's toyota 4x4 or 4runner with the 22R motor for a daily driver... engine rebuild kits for that engine are less than $200 -300 bucks all day everyday on ebay with new pistons too. Would be lovely to get rebuild kits for our cars that low.

all of the stock parts you are buying are NOS(new old stock), basically mazda stopped producing almost all parts for the FC a number of years ago, you're just buying what's left on the shelves. it will still be a few years before the rotor housings run short, then the rotors, then the irons, etc, etc, etc.
but problem is it's getting more difficult to piece together used engines for budget rebuilds. even with a single iron replacement would push even the cheapest rebuilds to around $2k or higher(unless you have a 100% good core).

Maybe Mazda will make a new rx7 and give us an option of buying a new car. Outlook doesn't look promising though. 16x or whatever has been talked about for years and seems like its only a concept engine. I should have bought an FC back in high school 6 years ago.

the competition department is also in LA, along with the big warehouse where they keep all the competition parts. maybe the engine wasn't ASSEMBLED in japan, but that's where everything else came from

part of the reason there are so many used parts in japan, is because they replace the irons, housings and rotors, so that "good used" part came out of their junk pile.
i've done a few builds with NEW irons, housings and rotors, and those engines always run better.

Can't blame Mazda, like others said, our engine only fits one car and there are too many neg press from people who has zero idea what he/she is talking about. so it's totally understable for Mazda to discontinue older parts.
I guess maybe it's time for me to start "storing" new old parts ... hohoho
