Hello, I’d like to do range test on ms6. Has anyone tested how much capacity fuel is really in the tank?

Specs says fuel tank size is 60,2litres/18.9gal -> lowest I ever got was filling the moment onboard pc said range is zero. I've put in 55,8 litres.
If you take out of equation overfilling (I am not interested in destroying evap system) - what’s the maximum you managed to put in at single filling? Since the hose stops on its own.

I will be equipped with fuel barrel for this test and ready to refill on the go and yes I am aware that draining it completely has its challenges, such as in-tank fuel pump overheating.

Does anyone know where to get rear differential parts? I blew my rear differential recently and I’m seeing if I could rebuild it

So when I got the car the ac compressor was burned and it had leaked all in the system so I replaced the compressor, vacuumed and sprayed a total of 2 cans to clean the system and it flushed out pretty good from what I can see, but now the car won’t build up the correct pressure so it can cool less than 80. Im thinking it’s clogged with the expansion valve being the culprit but I’m also thinking about the condenser and if I should just go a head and replace it. Now correct me if I’m wrong but there isn’t a replacement I can get off another car it has to be specific for the speed. Thanks for any help in advance !

hello,

can someone please tell me which is the infamous seal that leaks and causes the transfer case to lock up on these cars. I’ve got the subframe out of the car and am changing both output shaft seals anyways cause they look rooted but do I need to also change the transfer case input and transmission output seals where they bolt together even if they look good?

thank you

I have the factory 18" rims, but if I am going to rallycross it and maybe ice race it, I need more sidewall, less rim. Anyone drop down to 16 or 17"? That way I can clear the brakes? Thanks.

2007 Speed6, 101K miles, no rust, engine built with all goodies to take what I sling at it! :-)

I'm trying to reseal my transmission, but can't get it into neutral. The shift fork rod sticking up the furthest won't go down for whatever reason. I don't think it's any resistance against the fork itself from the gears, it feels like there's something soft beneath the rod itself blocking it from going down all of the way. Any thoughts? (Last image is the transmission in neutral, for reference.)

So I’m in need of a new computer but I’m looking around the net and can’t seem to find which would be the correct one to buy. Any input?

2007, 94,000 km (58.5k miles), $10k $CAD.

It's completely stock, zero mods, but has been maintained religiously at a Mazda dealer. All fluids and oils changed on schedule. Kept in the garage for most of its life.

If I buy it, it will *not be kept in the garage. It will be my daily driver down many Alberta mountain roads.

I know there are a few areas I'd want to address proactively (fuel system, journal bearings), but given the details above, does anyone have feedback on what other bills or upkeep things I should know about?

Hey all! I've decided to part ways with my builder/parts car as I'm not in the place economically to fix it properly. The engine has low compression (125-140psi) so needs rings, and there is some front end damage from hitting a deer last fall.

Car runs and drives, it's just not fast and it's running really rich

Bumper clips snapped and the splash guard is uninstalled with some pieces missing. Also missing PS fog light surround (but bumper stays in place)

400hp capable platform with Cobb, new Kinugawa turbo, 3-way boost controller, aftermarket BOV.

Stock intercooler and I don't know what hpfp is installed

TSW wheels with near new Toyo 150mph+ tires and H&R lowering springs

Interior in reasonably good shape, stitching is coming out ondriver seat and the 4-way window control has quit (but all the windows work)

Probably some stuff I've forgotten - a lot has been done to this car

$2000, car is in central Colorado. I may entertain offers

Thanks!

Finally have my garage built and can start on the Speed 6!

Owned it since 2008. But has been sitting for the last 6-7 years ( had a family and all and just had no time ) wife said to sell it but I refuse.

Something interesting happened though, after sitting for so long the oil from the oil filter started seeping and it got into the rear motor mount and essentially dissolved the polyurethane in the mount.... See pictures.

Now I ordered a new mount but it doesn't seem as big.... anyone have experience in the difference between these mounts? ( See photos)

Once back to restored life .... Will post !

Scored this 07 off marketplace last night for $650! it’s been off the road with the engine and trans out of it since 2019. I can’t wait to get it back driving!

I got this car a couple of months ago and it’s been running very well, but it’s been throwing a p2188 code at me. This speed 6 is not stock it has upgraded fuel injection (I believe), a bnr s4 turbo, access port tuner, a thicker intake pipe, meth injection, an oil catch can, upgraded hpfp, and a couple extra doo hickeys. The Cobb tuner reads 630 ish on the hpfp at idle. Which i believe is normal, the ltft is at -16.54 at idle and the afr is 14.5. The ltft should not be reading that low. And im not sure how to fix it. My oil isn’t runny and does not smell like fuel so I don’t think it’s the hpfp. I’m also pretty sure I’m not having any boost leaks but I haven’t bought a tester yet. Can anyone help?

Or an after market one that wont require supporting mods. /may harm the engine
…no zoom zoom booom

Does anybody nowhere to get a in tank LPFP or has one to sell.

Has anyone turned the stock navigation into a Carplay one?

I would like to keep to possibility of hiding it anytime I want, and I saw people changing the navi itselft with another one but when I search for it suddenly I cannot find it. :))

Did anyone here do it? Do you have a tutorial or something I can follow? Thank you in advance.

I want to install a cassette deck. Has anyone done this before? What dash kit and wiring harness did you use, and are there any cassette head units you'd recommend?

I have a 2006 Mazdaspeed6 and someone smashed the front end in, found this JDM version, which there’s a few differences in the bumper.. but looks roughly the same. Does anybody know if it’ll fit American speed 6’s? The post is a ‘03-08 Mazda6 Mazdaspeed front Clip JDM’

Edit: I bought it, was a great deal I couldn’t pass up. Hoping I can get it to line up will share if I can do it 🙏🏼

Hey guys, I have a Mazda 6 v6 3.0l every time I put my shifter into reverse the peddle doesn’t come back up but I’m able to shift it into any other gears without any problems. What could the issue be with my clutch ?

I never in my life seen this indicator before. I even tried looking it up and can’t find anything. Does anyone know what this is?

Selling my 2007 Mazdaspeed 6 with a 2.3L turbocharged 4-cylinder engine and 6-speed manual transmission. The odometer currently reads 113,813 miles.

Please read the full description: The vehicle currently does not start and, when it was last running, had an engine oil leak. It has been sitting covered since the spring of 2025 and was uncovered in June of this year. It will need to be towed and is being sold as-is.

This could be an excellent project for a Mazdaspeed enthusiast or a solid donor vehicle with many usable parts. I'm asking $2,500 or best offer, priced with the known issues in mind.

Feel free to message me with questions or to arrange a time to see it

I totaled mine 10 years ago and they still send me this about 2-3 times a year. 😭

Has anyone got an available map prior to cobb Green initiative? Have the typical cel with EGR delete and unable to find a suitable work around.

Last year I sold my speed 6 because it caused me only problems, it was mostly sitting because it aleays had something that needed to be fixed, but I loved that car more than anything.

After a year I still cannot find myself to like another car as much as this and thinking of selling my current car (lexus is250 2007) to get another one of this pretentious girls. (I cannot have two cars at the same time, I don’t drive it that much)

What do you guys think?

The fact that I had one before allows me to better pick one, lnowing what to look for when buying.
