I've searched, and read through a few threads, but basically I'm looking for a replacement catalytic converter to allow my RX8 to pass the MOT emissions test.
It has a Petit Racing/Milltek exhaust from the manifold back, this includes the cat-back section and either a resonated decat mid pipe...

Any guides out there?

Hi all, hope you're all having a fantastic day :). My car should be celebrating its 50,000th mile but instead, I've got a myriad of issues that have all seemed to crop up at around the same time and seem to be getting worse. I've tried researching around and have already tried several things, but...

The day we all dread. How much more to keep on the road another year......here is your answer:

Relatively not as bad as could be. £25 increase for 2007 on cars.

What are you all using? What would you recommend?

Supermarket delivery van scraped the family wagon while turning around on the driveway.
Only front bumper and light/fog light surround damaged. 'Tis merely a scrape'

Driver fessed up no problem, completed details on the scene, all good.

Now the supermarket's insurance co have got involved and...

Ever since my engine rebuild 3.5 years ago, the engine has never quite felt the same at the top end. No problem elsewhere in the rev range. Soon after 8k there is a little but sudden drop in power. It's only noticeable in 3rd gear and higher, and I've only carried on to the red line in third -...

Good morning
It has been a long time since I posted,I still have both cars.
I was looking at the track car yesterday and realized I have not done a track day in two years and I think it is because of the cost for one day,I am in France so my costs will be different to the uk.
This is what a normal...

Hi all,
So i carried out a compression test on my R3 today using a compression tester I bought on ebay (I know, says it all but I just wanted a reference and the reviews were positive.)

Anyway, I ran the car to temperature by taking it for a 20 minute drive, parked up, jacked up, removed passenger...

:-k

Hi all,

What I thought was just a system glitch while it was icy out is probably just a proper issue now.

I've had the TC and ABS light come on a few times in the last few weeks, with no real correlation as to what it could be.

However, last night, while coming out of a junction, I felt the...

Hi all,

After parking my R3 on an incline, I noticed the fuel gauge has been playing up a bit (was showing more than what it has). After a few drives and it being parked on flat for a while, I went to refuel and the gauge hasn't moved. Is this likely a sender that needs replacement? Interested to...

Hello All

So I've got a small issue with the climate control on mine, where the set temperature doesn't seem to match the reality in the cabin
So If I set 18 degrees say it tends to be too hot
I have to come down to 15degrees to force it cold and then its too cold
switch it 16 degrees and its...

I understand the UK didn't get the keyless entry option, but y'all might still have suggestions on fobs/electronics in general. [-o<

I'm discussing purchasing a key card fob tomorrow from a local seller that appears to focus on parting out 8s. My 2007 only has one key, so if I lose it, I'm gonna...

After briefly trying a rubbish £5 ODBII adapter, I splashed out on a Vgate iCar Pro 2S which was recommended by one of the bits of software I was using with it. However, it seems that most software needs to be kept in the foreground on my phone (an iPhone) in order to keep logging. I want to log...

From the conundrum I had earlier in the year with the rear wheels rubbing against the car, and just generally upgrading old parts, i’m in need of some coilovers.

Originally I was looking at the Tein Flex Z coilovers but saw that some people didn’t get on brilliantly with them.

Ideally I need...

Driving two days a week. Mostly cold starts.

And what better way to spend it than geting and fixing a race car :xmas-wink:

Have a great holiday everyone :inlove: :inlove: :inlove:

I've agreed a deal on a 192 with 60k miles, serviced every 3k up to 50k and then the last owner did it himself with no proof (classic) but the oil is too clean to be 10k old so I'm happy to take their word.

Anyway, the oil is fairly low on the dipstick, and I need to drive ~100 miles home. Without...

Hi All,

Just wanted to pop a quick post up as I’ve not been very active on here the last couple weeks!

First of all, apologies from me, I have been moving house, and therefore not been overly active, however, I’m now almost settled, so should be back and active again over the next few days!...

I’m about to get my track rods replaced - would anyone recommend Mazda parts over third party replacements? It’s about £100 instead of £270 for a Mazda pair.

I stopped work for lunch today and unfortunately saw the budget
I then decided it wasn’t safe for me to go back up on the roof in a state of shock
Two choices (suicide or take the RX-8 out )
As I’m still hear ( you guessed correct )
I warmed her up, wound the windows down and let the scream of the...

So then chaps
having recently fitted a COFS setup what oils are others using ?
reading up on it so far Castrol 2T keeps popping up

was using a Motul as premix before but apparently not recommended for direct oiling

also mineral or synthetic ?

thoughts please
and if anyone has ever done or...

Hi guys, got a phantom blue evolve, I'm 32, plan on passing at some point in the new year.... I've got insurance qoutes (I'm not moaning) coming back at £1,200 without a black box, fully comp and 2 years NCB, anyone know of a company that will do it for roughly the same price that don't mind mods...

So then peeps

Our cars by modern standards are frankly terrible for fuel consumption
my car is a 231 , 2008 with 80,000 on the clock. Open exhaust with a 200 cell cat, home made intake, RRP coils, a SOHN conversion and my own tune
I've also got a 'turbogauge' fitted that shows live MPG from the...

Hi everyone,

So we (me and husband) have been toying with the idea of buying another RX8 (likely an S1) and disassemble it to the last screw so that we could completely repaint the shell and other parts and then rebuild it again. Can anyone share experiences about what we would be signing up for?...

I’m planning to remove my front seats this weekend to give everything a proper clean. Before I do, I’m wondering if disconnecting the wiring will cause any issues—like ECU or airbag warnings—or if it’s simply a matter of unplugging, cleaning, and plugging everything back in. Any tips?

The other day (when it was very cold) I was half way into an 30 mile journey and suddenly my warm blowers started blowing cold.

I drove steady and checked the coolant later and there was just a bit of trapped coolant sloshing in the bottom of the header tank it was basically empty, I topped it up...

Check out what I was quoted for new Oil Cooler prices from Mazda today:

N3H114700D - £1042.78 + VAT
N3H614700D - £1042.16 + VAT

So if you needed a pair of oil coolers you're looking at £2501.93.

That's more expensive than the cheapest RX-8 listed on autotrader.

Wow.

I recently purchased more of this oil online and the name has apparently changed from 'Semi Synthetic' to 'Synthetic Based'. Has anyone else noticed? Will it affect rotary engines?

So after spending over 3000 on cutting out the rot of my sills I'm committed to keeping my 8 for years to come and I need some way to store it when not in use. I have a single garage I rent away from my house. I have ply lined it and lined the roof with polythene to stop any dust or drips getting...

I'm trying to replace my secondary air pump relay but having difficulty finding it. I believe it is in this compartment.

Would anyone be kind enough to point me in the right direction?

So, what could go wrong with an annual service on a 15 yr old Mazda 6 diesel? The family wagon.

Well it could be picked up, driven and you could notice the smell of fuel/oil coming through the air vents when sat in traffic and think nothing of it for a couple of days.
As it got worse, you could...

Hi,

I saw some PZ sports mirrors going up for sale on FB marketplace. I checked the parts catalog, the parts number seem to match, but if anyone could confirm S1 mirrors would fit an R3 that would be appreciated.
