OK, finally made it all the way through the thread!
I have now learned that I don't want Atkins apex seals or gaskets. Guess I bite the bullet and order from Mazdatrix or Pineapple if I need them.

That latest FC is certainly a showcase of PO fuckery.

I've probably mentioned in other threads that I own 7 RX-7s, 1 SA, 1 S2 and 3 S3 FBs (including two GSL-SEs), one S4 FC and 1 S5 FC. As you might expect, out of those 7 RX-7s, exactly 1 runs (the S5.) I've avoided the FDs, because I don't hate money. Also, I barely fit in the damned things. Somehow, the FBs and FCs have more headroom.

I picked up a spare S5 engine several years ago. The dingleberry that had it bought it as a spare for his autocross car, but stored it completely open - intake, exhaust, coolant, everything unplugged. It was at least in a garage. He also didn't dump any MMO or ATF into the chambers, and it was stuck when I got it. I got it unstuck using a tool made from an old starter for the purpose, but, of course, I have compression on only one face of one rotor. Looking inside, the seals are intact, and nothing looks beat up, but the apex seals are stuck in the grooves by carbon and smutz. Do you (or anyone else) have any suggestions for a chemical to dissolve said smutz? ATF doesn't appear to be strong enough. I'd really prefer to get this thing operable without cracking it open, since it's like $1000 just for all the damned soft seals. The plan is to drop this engine in my '79, which lost the oil control o-rings, and thus compression AND all the oil, some years ago.
I mean, if it has to come apart, it will, but I'm a cheap bastard (see the part where I don't own an FD. Or even a Turbo II.) The housings on the 12A are probably good, since it was the oil control rings that went, but I've not taken it apart, and it's not really cost-effective to rebuild a 12A.

I plan to sell the running FC and one of the GSL-SEs and dump that money into the '79. It's solid, but like a lot of old Japanese stuff, it needs the interior refreshed, and there was a rust issue in the rear quarter under the radio antenna that a PO let leak. Already has the suspension and rear axle from one of the aforementioned GSL-SEs, so has decent brakes and a common wheel bolt pattern. I really want that FrankenRex to live again, since it's literally my first RX-7, and was a bastardized mutt even before I got it (it had an S3 engine in it that I got properly wired up to run, and drove it until it coughed up an apex seal. Then I put in a '80 12A of barely known provenance, and ran that until it died.)

I really enjoy reading about your efforts to keep rotaries alive. Kinda inspirational. :) Makes me wish I lived closer, except for all that cold wet stuff in the winter (I'm a Texas boy, so that much snow is... evil, or something.)

If you are looking for something for the carbon locked seals, try out http://www.lubecontrol.com/products/lc20-gallon.
They have a bunch of snake oil claims, but something it certainly DOES accomplish is turning solid carbon into a slimy lubricant / colloidal graphite. If you mix it with ATF at 70% LC20 to 30% ATF, it makes a penetrating oil that dissolves carbon. Pour that in the spark plug holes and turn it over with your tool occasionally over the course of a few days. There's a review by a chemical engineer over at the Bob is the Oil Guy forum that you can find here: http://www.lubecontrol.com/pages/dyson-analysis

Sweet mother of god. I finally found a set of Spirit R 17" wheels and they were under 1k! I've had some "knockoff" PIAA racing wheels on my 94 Chaste White that were pretty close (I'm still convinced PIAA just copied them anyways), but I've always wanted a set. With the average selling price around $2800 and going up, they've been low on the priorities list. This means I just need the Recaro seats to have a complete "replica" 2001 FD in LHD.

Here's the first picture the seller sent me. Not bad, little dirty and a few scuffs on the paint.


I'm sure they would clean right up with some elbow grease.

FUUUUUUUUUUUUUUU.
Ok, so the reason they were so cheap is the seller decided to strip the wheels and have them painted. He apparently found other wheels he liked better and tossed these on a shelf mid process. I'm a bit concerned about them sitting after being stripped, who knows if he neutralized the chemical stripper properly. But what the hell, might as well see what they actual look like in person.
:shepspends:


"Oh, I have these rare wheels - I should strip and paint those a non-original color, rather than buying knockoffs or similar wheels and painting those" - idiot PO.

also, I'm disappointed that there's no overnight option on Croooober.

The issue I see with that around Portland is that you still need to get it through DEQ. How are the emissions on those typically?

If everything is working right, no problem. They tend to be high on HCs, typically. Fortunately, my '90 RX-7 has been exempt in TX since 2015, because it seems to be running rich for some reason, despite a fresh O2. A little E85 got it by the last inspection. At some point I'll figure out why the ECU is doing that (no check engine light, just runs a bit rich.)

The descriptions on the corner seals was confusing me. I was thinking "when did Mazda use 1mm Alex seals?", but the next pic pointing out *side seals* cleared it up.

Well, that's just silly, as we all know the bits just embed themselves in the rotors and subsequently destroy the chrome plating on the rotor housings. Or wedge between the rotor and housing and stop everything dead.

It does make the project take longer, because you've got to set up shots, and explain stuff, and make it clear, but I would definitely watch rotary tech/project videos.

Jumping way back. The first part we had made was the shifter relocation. I've hit a major dilemma here. We originally were going to have the "cup" piece machined. Turns out it was going to be ~2k in tooling/material/fixtures. So we modeled it and my buddy had it printed in Acrylic. A few revisions later and we had a working part. The idea was see what 3d printing it in 316 stainless using SLS would cost. My first quote from ProtoLabs is..... drum roll. $1900. drat it. I may just scrap the idea here and use two of the core transmissions to hack together another one like the prototype pictured. I can buy trans for $200 and since I only need 2-4 of these, it's cheaper to buy the trans. Another option is to just make the little cut piece and weld/braze it on to the existing piece in the trans.


Could you maybe cast one using your printed parts as molds or masters?

That’s the one that goes with the kit. He decided to go with the repro Rocket Bunny bumper since it has those extensions to the flares molded in, and the repro RE Amemiya he had was poorly made. He added a splitter to the bottom that also improved the look, getting rid of the receding chin.

I suppose you could reason that those cover “muscle” and “sportscar”, so the Corolla could cover, I don’t know, “‘80s shitbox”? Follow up with a pickup and a wagon, and I’m good, right?
