Dunno. I guess they are getting to be a rare thing these days, what with people going backwards and swapping manuals into them

Mine flared in 1st gear on three separate occasions last year some time. I checked the fluid levels and it hasnt done it again. Nothing else out of the ordinary to report for it. Mine is going on 21 years on the original engine + automatic. Which must mean something..

 

Still ridin' slushy here. I haven't been paying much attention to the car lately due to other cars demanding more of my attention.

But, the transmission I swapped in has been holding up fine through me beating on it at Autocrosses and just general driving to shows/events. After, I get it re-registered this time I might throw on a High-flow cat, PFC, and some injectors and see if the trans can handle more power.

 

The Auto trans can hold plenty of power, we have ours at 14psi sequential, with full exhaust, intake, 850/1300 injectors, SM intercooler, Power FC with our adapter, 4.30 rear etc... it spins the tires every time it shifts into second. Pulling the engine next month to street port it, then we will put it on the dyno.

 

Good to hear, I have one of your harnesses to go on along with the PFC. I was planning a similar setup to yours only I have 4.44 gears in the rear and will probably stick to a max of 12 lbs since my turbos have 100K+ miles on them. That is my intention anyway, boost creep may have something to say differently once I get the full intake/exhaust on.

Keep us informed with the numbers. Are you going to do before/after graphs for the port job?

 

Nice to hear. You have had to rebuild your engine during this time though right?

 

No, original engine and trans, never cracked opened. I still have good compression and no major mechanical faults (although I am chasing a relatively minor cold start warm up system fault where it runs rich for a few minutes)

To be fair, this engine has done 108,000km of work in 21 years. No go-fast parts or anything added apart from a boost gauge and water temp gauge.

I have this feeling that the autos are longer lived because they arent thrashed as hard as the manual cars. They have a more sedate life maybe?

 

I treated mine very easily until I blew the motor while driving it gingerly at 90,000 miles (145,000 km) it was my only car at that point so I wanted it to last. After seeing how much carbon had built up on the rotors I'm not sure if what I was doing was helping or hurting it.

That said, after the rebuild it's life hasn't been sedate at all

 

How have the auto boxes been holding up? Has anyone put more than 480hp through them yet?

 

 

apology for going full-necrobump, but I’m looking for REW automatic trans rear irons,

please pm me if you have one (or more)

at the moment I’ll accept one in **any** condition even if not reusable/trashed/etc.

After that I may become more selective.

TIA.

I smell a DCT..

 

question for the wankel veterans; I understand the differences between the main RE and REW rear irons, but I’m thinking the placement/profile/machining of the automatic starter area would match up between them? Not having direct experience on this though, I’m not sure.

Because at this point I’m mostly of the opinion that machining a manual iron is the ultimately going to be the only real solution to this situation. It seems doubtful that Mazda will ever produce them again. So then it just becomes a matter of having something to work from to take a manual iron and replicate the automatic starter area onto it. It seems that the Cosmos rear iron is likely to be easier to find for this purpose if they match up.

What are you trying to accomplish? Based on some DCT installs, I know the manual iron can be cut down to allow room for the auto starter, there is plenty of meat. But I can’t quite tell what you are looking to do. The DCT kit I use is thick, so that leaves room for mounting the starter, not sure if you are doing something different though

 

yes, it could always be hacked off in any old fashion, but my preference is to handle it a bit more elegantly if possible. I’ve see enough out there that seems to confirm that the RE starter area matches the REW auto. Those seem to more readily available at the moment, but I’ll keep searching around and consider that as a fallback since the situation doesn’t accommodate using an RE rear iron instead.

I’ll take a picture for you when I hack off mine haha.

Have you called any shops? A few shops have piles of old parts from leftovers over the years. Might be worth calling a couple, maybe banzai or pineapple racing or something.

 

I contacted a notable rotary specialist company that has the capability and skill to machine it, but also inquired if they had one. They want to push me toward a Cosmos iron(s) instead. That doesn't work for mounting the engine in an RX8 chassis plus dealing with the other mismatched mess it creates. The post covid world seems to have transformed men into weaklings. No thanks, pass.

Banzai sold what was probably the last NOS one on fleaBay earlier this year. I had a WTB ad on here, but missed it over there.
