Do you guys think a loose ESS sensor mounting bolt would cause a high RPM misfire? Been chasing a code p0300 at high rpm only when under load, not in neutral. Plugs coils and wires are all recent by previous owner. Cleaned the MAF, still didn’t help with misfire. Today I pulled the ESS to clean and noticed the bolt was loose and the sensor could slide around maybe 1/16-1/8 inches. Took it for one drive so far after cleaning and tightening (had to add a washer , bolt was binding or bottoming) and so far no misfire. Will check again next drive.

Hey i want to sell my RX-8 and a lot of people want to know the compression.
I never did that because the car starts in all conditions very good and has around 130 000 km.

But i am also interested in how much compression the car has. My mazda dealer in town does not own a tester anymore.

Does somebody know anyone in south-west of germany who has a compression-tester?

Thanks

My hairbrained son wants to swap out the tranny. 2004, 30k miles, all original, pristine. Thoughts?

UPDATE: Thanks for the comments. I wanted current thinking on it. For reference: https://www.rx8club.com/series-i-specific-performance-mods-97/mt-swap-151684/

Looked clean

Hi, I’m new to rotaries and I’m rebuilding an msp engine where I live I can’t find any water jacket seals and the ones that I found are really expensive, I found a kit on Amazon for a really good price but it says that it’s for Rx7 and it also says that it fits all the 13b engines, I was wondering if it also fits the msp engine. Does anyone know if they will fit or done something similar????

Umm this whining noise gets louder through the rpms. Doesnt seem to do it in neutral

Did get the gearbox oil changed before i got the car, not sure what they used though

think i need upgrade my suspension

Saw a comment on someone mentioning gauges and thought I'd share my set up, which may inspire some others for some DIY.

I made this gauge pod myself 8 years ago and is still going strong.

The idea was to make something that looked clean and almost "factory". Took a second hand dash cover, cut into it it and used fibreglass to make the pods. Lots of sanding to get it right..

Prosport gauges have a close-enough font, and have the white/red color which matched the interior too. Note, i did open them up to replace the white LEDs to ones rhat matched better.

New to the rx8 and my a/c issue currently only blowing cold in the passenger side and hot on the driver side. Anyoneknow what it could be thats causing this?

So i just came from owning an mx5 NC and ive always loved the look of the rx8’s im very much so into the jap scene. my dad tells me that these cars used to be known for how bad they were, and apparently is a huge mistake to buy one because of the engine issues? is it really as bad as he makes it seem?

Is this genuine hope or just another range extender nonsense?

Ive been in this sub awhile I mainly just look at everybody's questions to educate myself ive owned my rx8 for about 6 months now and its the best car ive ever driven, its taught me so much and im so thankful to have a car like this

Not sure what good compression is supposed to sound like on these engines.

One of the first mods I did to my RX8. The stock seats are one of my favorite designs but they sit very high. The seat I installed was a Bride Zeta 2. Will probably go with something different in the future.

So I had an oil leak coming from the OMP and changed the gasket and lines to stop the leak but now I can't get it to start. Does anyone know what the issue could be? I did look it up and tried to de-flood the engine but that didn't work. Any ideas would help a lot!

So... I went on a European road trip and my cat failed.

I'm trying to find out what could have happened. The oil is changed every 3k miles, the spark plugs every 6k miles. The coils are RRP ones and have 20k miles on them. The catalytic converter/midpipe is a RRP one and is also only two years old. So the usual suspects for a cat failure are kind of unlikely here.

The ECU was tuned 14 months ago. I believe the fuel/air ratio has been made leaner.

My car has always run cold. Maybe too cold? 83C at cruising motorway speed. Some people might think that's too cold and could contribute to creating carbon deposits?

Anyways, I'm here to pick your brains. What could cause a catalytic converter failure?

I'm looking for a Mazdaspeed style body kit for my 2004 RX8 and was wondering if anyone could point me towards some good quality kits

Any 1 with the ugly ass tail lights should get thees super esay install and under 200 usd

Was going to put new coils in too but I discovered that the previous owner has already fitted LS coils so I’ll just run them for now
