Could not find a good phone mount that worked well for my Rx8. I hen I noticed the hole that is between the radio and the glove compartment. It is covered with a small plastic cap. Took some measurements and designed and installed D printed a holder that fits perfectly in the hole and has a 17mm ball to attach any 17mm phone holder. Found a 17mm Ball Mount Extension Adapter for Car Phone Holder on amazon for around $5. Then I 3D printed a holder for the apple magsafe charger and it works great. Let me know if anyone is interested in getting one.

got versatune lite last night, flashed the prebuilt stage 1+crackles and pops cause i wanted to try it. Really liked it at first, until i realized that they didn't stop and continued until i hit the gas again. I really only want 2-3 pops, is there anything i can do or do i js have to buy the full version or run without pops.

Hello everyone, as I am nearing end of my first rebuild I thought why not to refresh everything I can before I put it all together

So my question is,

What ignition coils do you recommend ? Do I stick with OEM ? Go for LS coils or some other brand ? Dame goes for the cables,

Is there anything else worth renewing ? Like all hoses mounts etc ?

And if so could you point me to what brand would be the best for mostly stock engine ?

Some pics of the build so far included

Hey,

I was kinda annoyed with the temperatur dummy gauge, already had an Veepeak OBD adapter, didn't want to wire additional things around in the car + didn't want a phone running all the time.

Also I am just rationalizing tinkering around on a rainy weekend.

Anyway, came up with a little wireless gauge that connectes to the existing adapter over BLE, and figured I’d share it.

It runs on a round ESP32 touch display and connects directly to a Veepeak BLE OBD adapter. Similar adapters should work as well, tho I have not tested them.

Coolant is the main reading, and you can tap to switch to MAF. In principle other exposed values work as well.

So far, it's okish tested in simulation (based on captured raw telemetry), basically verified and works in the car so far. But it is still very much a prototype and work in progres.

I’m also designing a removable cradle; that hasn’t been printed/tested yet. The fancy picture is a render.

Firmware, simulator and CAD are all open source / public domain. Maybe this is useful for somebody.

I took my Miata for a trip to the grocery store, currently in remote Virginia for work. It’s about a 2-3 hour round trip to get supplies and back to my apartment.

On the way back, I see this RX8 pulled sideways into a driveway, smoking profusely. I flipped around and checked on the driver, looked under the car and saw flames. Flagged down a tow truck driver who attempted to put it out with an extinguisher, unfortunately wasn’t enough.

He called 911, we sat together and watched her burn until they showed up. Poor guy’s first car, he was understandably pretty upset. Gave him a hug and stayed with him until all was said and done. If you’re here, I’m so sorry dude. You’ll build back better, keep your chin up.

My son’s 2004 RX8 MT6 has been having PO850 on and off indicates an
Input Circuit Fault in the neutral/park safety switch system and also trigger an idle hunt. I have checked the circuit with both white connectors taken apart. Down stream to the neutral safety switch is functional and is close when in neutral position. Upper stream was open not closed, until I rocked the shifter. My question is which part do I look into to get this repaired? This seems to indicate there has to be a switch telling the PCM to send a signal to confirm that gear is in neutral position inside the transmission, and which part is it? A lot thanks to you RX8 masters here!

Hey guys, was watching a YouTube video earlier about how some girl got stranded cause her clutch pedal mounting bracket was cracked. Since I'm trying to minimize my chances of getting stranded, I decided to take a peak at what my bracket looks like. The bracket looks fine I guess, and my car shifts pretty good but I noticed some oil leaking there. Is that brake fluid from the master cylinder? Is that normal? I was looking for the master cylinder reservoir, but it seems it's hidden somewhere by the trans and the clutch slave is by the fire wall? So do I need to take care of this before it's too late? What to replace? Thanks

When I bought the car last month i had already fixed up a bunch of small things. Owner sold it to me with good compression. I know gas mileage is horrendous on this thing and it is a weekend vehicle for me. But I didn't realize it would be this bad. I had cleaned the MAF sensor as i was having a rough idle and fixed a few vacuum leaks.

This thing has an aftermarket intake/exhaust, and the intake is a HAI. Would reinstalling the factory airbox or maybe the racingbeats one give me better mileage?

when it was sold to me I was told it also has a "conservative" tune on it. Is it possible the tune is bringing down my mileage?

I'm starting to think maybe a used 2022+ BRZ or a Miata might be good for me.

edit: wanted to add that I'm at a quarter of a tank used right now and im at 90 km. So I'm doing slightly better. I also add 2 stroke oil, and have a cat delete. Going to try another bottle of fuel cleaner to make sure nozzles arent plugged (which got my abarth better mileage)

About to drop this rebuild in and not sure what route I want to go. The clutch that came with my 2nd parts car looks brand new other than some.rust from being mounted on the engine. But I can't seem to track down the exedy part number online. I faintly remember finding paperwork from exedy in the car that said something about a stage 1 or stage 2 clutch but it had gotten wet and was moldy so I threw it out thinking I'd be able to just use the numbers on the clutch.

I've attached pictures of any numbers I could find on the clutch/pressure plate. I'm mainly asking because I also purchased a new "Rally clutch kit" from Pettit Racing, but I'm not sure which is better! I'm leaning towards just keeping the unknown one as a spare but looking for opinions.

I have never owned a Mazda RX-8, but I was always wanted one. I just saw one for sale. It looks very clean and it's 1500€, but it has no engine inside, so I have to get one. I could also get the old engine, if I would pay more, but it needs to be rebuild

I'm in the market for a catback. I already run a non-resonated 3" midpipe with a high-flow catalytic converter.

I have been running a Racing Beat Rev8 and it's been fantastic. But it has now died.

I'm looking for something a little bit more aggressive sound wise but I don't want the unit to drone at cruising speed.

Do I keep the Rev8, do I go with the HKS Legamax which has the reputation of being very loud? Or do I get the R-Magic RM tuned silencer which is designed to be quiet at low revs but goes into a high-pitch in high revs?

I don't mind decibels when I'm WOT, I don't want any droning around 3.5k rpm when I'm cruising on the motorway.

Any of you have any experience with the Legamax and a 3" midpipe? How is it?!

New wheels and fully cleaned <3 ready to go again!

Edit:

• Wheels have been designed and produced by me myself and i... - https://rimcrafts.eu/product/rotary-2/
• The rear bumper is from "A.C.E." stands for "Auto Craft Evolution" (imported it from japan)

Where ya’ll at

Does anyone have 3D scans or 3D printer files of the Mazdaspeed gauge pods, other center dash gauge pods? Also if you can point me to some already on other sites that would be great too.

So far I've only found two designs on thingiverse.

I know it's a big ask and that there are other options like ash trey pods, but I'm a picky bitch that really wants those slightly recessed triple gauge pods on the dash.

No plans or ability to make them in mass or even more than just 2 for myself. If they are your scans and you want to charge for the files we can figure that out.

hey guys i was looking at exhaust for my 2004 rx8 and i was wondering for some opinions. I want a loud but nice sound with pops. I've seen some like invidia q300, racing beat race exhaust and megan racing but im not sure what would be good for me.

Made some good money on my latest worktrip. I think coilovers are next... though it'd be great if my RMagic wing would finally show up soon.

does anyone have data of their ECT before and after changing their radiators? Mine seems to run at around (212F) on highway speed with the AC on. but temps stay in the (203F) when i switch off the AC. and the outdoor temp is at 100F.

My fans are working but i cant tell if they are working as fast as it should be. Stock setup fans and aftermarket cheap radiators. the chart above are from the same duration of highway drive.

Need some inputs of your rad/fan setups with temp data if you have it.

Hi again. (Yes i searched the forums and got more confused) Those who followed my few posts will know I am a new rotary owner and the car just rebuilt.

Currently it came from previous owner with stagger wheel setup Westlake SA-37 chinese tyres in 235/45/18 rears and 225/45/18 fronts. The wheels look wider in the rear as well, i suspect 8” and 9”.

However, I’m on a bit of a tight budget and tyre availability where I am is a bit iffy when it comes to staggered sizes.

Currently I can go with:

A) Nexen Nfera SU1 in 235/45/18 rears and 225/45/18 front

B) GT Radial Sportactive2 in 235/40/18 all around

C) GT Radial Sportactive2 in 245/40/18 rears and 225/45/18 front

I don’t do trackdays, rare curve road driving but i am leaning towards that maybe once a month, more of a “touring” setup. I am aiming for quiet nvh tyre with a bit more stability and grip.

The dark horse in the room is that my friend has an rx8 with Westlake Zupereco-108’s with 245/45/18 rears and 225/45/18 fronts and that is a quiet tyre with decent enough grip in city driving. Educate me, please? AI consultation been done over a few days already but…

So i bought my first S1 rx8 3 months ago. It has just 60k kilometers (like 40k miles on it). The thing is since day one its losing coolant. Compression gases gets into the coolant. I can still drive the car and I do drive it but i have to top up coolant after every spirited drive. Power delievery is still good but I cant compare it to a healthy engine to be honest cause it had this issue aince when i bought it.

Is this an easy fix for a mechanic that has no experience with rotaries? He is familiar with my mazdas but never worked on a rotary before. I can see the revuild kit is cheap so I thibk of going for it. Can there be any other reasons im losing this much coolant ? There is rarely white smoke and even only on startups some times. So coolant isnt goong through the exhaust certainly. Do I nust need apex seals done and that will be it? Ive already changed coils, spark plugs and injectors. Changed the expansion tank too did some other handling maintenance. I really like how the car drives so i want to always have an rx8 but it is better to work on this one i got or sell it and find one with good conpression ?

Also i have the synchros shot so every time i upshift to fourth gear there is this scratchy noise. it only happens after ive driven the car for the first thirty minutes, not roght away. Can it maybe be that i need a thicker oil or is it the synchros? Is that also sth I can work on ? Sorry for the long text

Just received this rx8 2007 that's been sat for 6 years. Worked when it was parked from what I understand but having trouble starting it. Engine was seized but broken loose by a breaker bar and filled with some petrol and a bit of 2 stroke mix. Car is cranking but unsure what to look for in order to get some life in the engine
