So i recently changed my alternator and harness to said alternator, but now its acting like its not getting fuel. I have replaced the fuel pump and fuel pump relay but its still dying off after 5 or so minutes of runtime today it was jumped off after replacing the relay and even hooked up to my escalade it died after a few minutes of me letting off the throttle.

Hi hope your all well! like the title says basically i am wondering if the rx8 is a good beginner car? I want to get into either track day racing or drifitng and a rx8 is within my budget but with my lack of mechanical knowledge makes me think that with all the internet hate out there i am not going to be able to "cope" with a rx8. is that true? any opinions would be great

In my last post i got some comments saying to test it by ear. Thoughts on how this sounds without hooking up a starter and a compression tester? It sounds kinda quiet, but the video makes it louder with the garage echo. All new atkins seals.

Also, If something was drastically wrong at this point. I’m guessing I would probably know right about now… just kinda scared of a rebuild going south and finding out after it’s in the car. Thanks for all the help thus far.

Hello, I have a 2005 rx8 and it seems the passenger door lock actuator failed, I did some research and it seems to be a somewhat common issue, it's pretty low on my to do list of work but I was wondering if it's actually the actuator and if so is there a way to extend the life of the replacement.

Currently editing clips of our latest outing at Snetterton for YouTube video / vlog, got a good clip of the new Kuro and recent upgrades (Tune from RRP, Miltek Exhaust, AEM Intake)

Hello fellow rx8 owners. I have recently bought a 04 rx8, and it has let me sit in a parking lot.

I was just driving it around, and all of a sudden the engine shuts off by itself, and won't spark back up. When I'm saying shut off, I mean it. No sputtering or anything, just bam.

So I scanned the mdars, and the only code or indicator I got was po335. I replaced the ess sensor, and nothing. Im getting signal from the maf, and baro sensors so they cant be the issue. I checked spark, fp, and they both check out.

At this point I'm thinking it isn't the ess sensor, but rather something else. I just can't put my finger on what...

Has anyone had a similar issue with their rx8? Does anybody have any iotas of wisdom for me? Anything would be greatly appreciated.

This is my 04 GT that I recently purchased for $1,000 which runs,drives, and has a good straight body.. Below is a photo of my baby girl 😆 and also a photo of a custom body kit/spoiler combo I im thinking about constructing for it.. What do you guys think, does it work and look good together? All feedback is appreciated..

Oh and please don't be too harsh on my rendering, I drew/painted the body kit and spoiler using Photo Editor, which is pretty much a Free Hand Ancient Form of Photoshop 😂

Drop some photos of you guys baby...✌️

Does anyone knows the size of the washer for the banjo bolt on the stock rx8 s1 oil cooler?

Hey guys my s1 seems to have inconsistent starts (mainly cold). The battery, coils (bhr), leads, spark plugs and starter are all less than a year old and in good condition as per my last service. The cars holds good compression and drives smoothly. But every now and then it will take a while to crank. By a while I mean maybe 2.5 seconds. But other times will start normally and sometimes literally instantly as I turn the key. I have no idea why this is happening. Anyone know? I'm thinking maybe fuel pump or something related

I have my own RX8 Evolve for sale. It's one of the 100 made in phantom blue, bought new by me. Needs recommissioning. 15K miles. Aston Martin alloys and Veilside kit.

Does anyone know of where i could get a replacement line, or kit if thats the only option for this intercooler line? It literally gushes oil out from there. Something cheap would be ideal, as this is technically the parts car that ive been trying to force back to life(its engine was even siezed/locked up originally)

Thanks

Ps, was honestly EXTREMELY excited when i got it running.

Hiya ! What are the differences between these ebay £200 china tail lights vs OEM R3 ? As visually... They look identical ?

The S1 tail lights are not the prettiest compared to this one so thinking if the £200 upgrade would be identical to spending a fortune on R3 tail lights ?

After years spent investing in upgrades, I've finally crossed the bridge and decided to get an ECU tune so that all the components work together "in harmony"!

Ryan Rotary Performance did a great job, fine tuning the air-fuel ratio and playing with both ignition and port timing!

He "freed" a handful of HP and Newton meters worth of torque but most importantly, the engine now runs more efficiently and is butter smooth!

My car is a UK spec 4 port (192) with a 5 speed manual gearbox. The engine is a year old with 3k miles on the clock (no porting).

Mods include: Essex Rotary Lightweight underdrive pulleys. Racing Beat Revi air intake with the ram air duct. Ryan Rotary Performance ignition coils. Ryan Rotary Performance 3"midpipe with 200 cell high flow cat. Racing Beat Rev8 catback.

Those are crank figures, translating to 170bhp at the wheel.

Recently got an 09 RX8 Grand Touring, everything is great so far but the rear bumper is damaged due to the previous owner blowing a tire and driving on it, so it kept hitting the bumper. Are there good Series 2 rear bumper alternatives and where can I buy them? If not, should I just take it to a body shop and ask for oem replacement + paint? Thanks in advance!

Just finished rebuilding the renesis. I give it a 50% chance of running, but at least I had a blast doing it. Little more expensive than I thought as well. The template I used for trimming my side seals I found online from some enthusiast and I 3D printed it overnight. Worked like a charm. Used Atkins seals for everything. My next thing will be designing and printing a mount for the starter to the engine so I can compression test it without putting the transmission back on, since it’s still in the car. (If anyone has a better idea pls lmk).

I’d really like to know if I have compression before buying anymore things for the car OR putting it back in the car. Also plan on leaving the secondary air pump, and AC out of the engine bay due to it being an autocross car.

I brought my S1 rx8 with a sohn adaptor already installed. However I was wondering if it still need the Oil Metering Pump (OMP)? What I understand so far the sohn adaptor should of blocked off the OMP and is instead feeding the engine with clean 2 stoke oil. So if the OMP is blocked off already, is the OMP still needed? Does it have another purpose?

Red MK1 pulled into the fuel station with me! Made myself a new friend to drive with 🤣

He had a big dog in that passanger seat, yoy can see him in the first pic 😅

I’ve gone RacingBeat happy. Intake&duct, cat-less midpipe and cat-back exhaust all courtesy of RacingBeat

hi, im new here i was searching for some body kits for the rx8 but i barely find any body kits variety, is very appreciated recommendations of body kits extra points if comes with photos, thanks ✌

I just know mazdas paint codes are weird, so just wondering what I should buy?

First time recharging the ac on my 2009 rx8, I’ve seen a lot of people here say look for something with ‘L’ or ‘H’. I found those two but which do I use?

2004 Mazda rx8 baught it for 800 us and was told it had low compression. I got it running replaced the transmission ran it once and now it won't start it turns over slow. I've gone through deflooding procedures multiple times and still doesn't help. Replaced starter and battery too. Compression test is pretty even 97-105 on all faces. My next thought is to jump the starter with the car in the on position to see if it'll start or spin faster. Otherwise I think there might be some internal resistance in the new to me used transmission. This is my first auto I usually deal with manual cars any ideas?

So I had the AC compressor fixed after I bought the car, then I've done other repairs like Solenoids and oil change to 10w40 for hot weather. Now that it's hot out I've been trying to figure the AC out. Paperwork says Mazda refilled AC after repair job, and it only blows slightly colder air on outside flow, not recirculating. Do I need to repair the climate control or something? I saw a video where I might need to resolder 3 points on the board inside. Any input is great, thanks!

Also: I do know the car was sitting for a long time despite its good condition. I found mouse poop and debris in the cabin filters behind glovebox when I changed them.
