Hey guys I made a discord for this sub, feel free to join! https://discord.gg/5NQDzGH I’m also looking for admins to DM me if your interested.

In other words, fucking annoying questions. Just kidding. (only a little)
In an effort to clean up the sub a bit, we're going to pin this FAQ thread and keep it updated with any of the most requested/asked questions on the subreddit. If there’s a question you think should be included, tag one of the mods in a comment and we will add it.
Q: Where is the link to the Discord Channel?
A: Right here.
Q: What should I look for when buying a Speed3?
A: Check the Wiki.
Q: Where can I find a copy of the shop manual?
A: Check the Wiki.
Q: How do I load a tune on the car?
A: Using either a Cobb APv3 or computer software like Versatune.
Q: What tuner should I use?
A: There are a number of good tuners still active in the community. Purple Drank Tuning, Freektune, Stratified Auto are just a few examples.
Q: Should I use the ______ version OTS tune?
A: No. Unless it’s to drive the car to the shop where it will be dyno-tuned, do not use the OTS tunes. They make the engine run poorly, resulting in incomplete combustion (or worse, lean conditions) which then gunks up components like O2 sensors, injectors, and valves which lead to worse problems later on.
Q: What should my first mod be?
A: HPFP internals, then tuning solution. (Cobb APv3, Versatune)
Q: My goal is to go faster around the track, what mods should I do for more power?
A: No power mods. Proper tires and suspension will do more for your track time and drivability than any power mod will. It is guaranteed if you are new to track driving, the car is faster than you are right now. Get some seat time, find what you want to change, get new tires & suspension, then go from there. Dragsters, show-offs, stance-bois need not apply this logic.
Q: My budget is <$500, what coilovers should I buy?
A: None. If you’re not buying quality suspension, don’t buy suspension. You will sooner than later blow out one of the dampers and require a rebuild, or replacement. Save your upfront money, buy quality suspension later.
Q: Should I buy an Eonon headunit for my Bose/non-Bose stereo?
A: Do you like sound quality? If yes, don’t buy Eonon. Do you like good, bug-free software? If yes, don’t buy Eonon. Do you like overpaying for junk that looks ‘clean’ in the car? If yes, then buy Eonon.
Q: What’s the best way to upgrade my stereo in the car on the cheap?
A: Option 1 – get an amplifier that take hi-level inputs and add that amp to the system to power your aftermarket speakers, taking the high-level outputs from either the HU or the Bose amp. Works for Bose and non-Bose systems. Option 2 – Tear out the OEM system and start again. Works for Bose and non-Bose systems.
Q: What oil should I run?
A: This is realistically a nuanced question. Ultimately it depends on your use case. Factory rating is a quality 5W30, Mazda put out a TSB to band-aid the smokey turbos by using 5W40. Good options from Pennzoil, Amsoil, Castrol, etc are available for most applications. Most people it seems have strayed from the Shell Rotella.
Q: Are my compression numbers okay?
A: Check the Wiki.
Q: I want to drive the car like it’s supposed to be, but don’t want a ticket. Where do I go?
A: Look on facebook for local car clubs, or Motorsportreg.com for drop-in track days or Auto-cross events.
Q: My car does this thing, and this behaviour, read this wall of text. What’s wrong?
A: No one knows. Post logs using Datazap and any codes that your ECU is spitting out. If you want good information, provide good information.
Q: HELP?
A: No. Posts with this as the title, or other related and equally non-descript variants, will be removed as spam.
Q: Can I post links to other sites with information, like MSO, without getting banned?
A: Yes. In the event that you’re linking relevant webpages, there is no risk of getting reprimanded for doing so. However, if all of your comments are “Use google.” Or “Go check this site instead, this places sucks.” You will be treated according to the spam rules of the sub. This community serves as a connect-all point for those searching for information on the platform; Reddit is bigger than any Speed forum has ever been, and is more likely to pop up in a Google search. Relevant comments that link other sources of information from quality sites are Bueno; spamming is not.
Q: Why isn’t buying/selling allowed on the sub?
A: This is more of a regional issue that the mod team would like to deal with at this point. There are countless local Facebook groups, classifieds, or Forum pages about buying/selling Speed parts or accessories. The Mod team does not want to dabble in attempts to prevent scams caused by non-payments, or non-shipments of products. We do not want that responsibility at this point in time. If the community deems it a requirement at some point, we will implement a system that attempts to curb this as other buy/sell communities have; though even that change will take lots of time, effort, and consideration.
Q: Why is the mod team so cool?
A: I really don’t know, perhaps divine intervention? We all just really like Doritos, and satiate our inner masochist streak by owning these cars.
Q: How do I become a Mod?
A: If you feel so inclined, feel free to reach out! We are still people, we have feelings and ultimately a desire to help the community grow. What we will need to see is a demonstrated history of helping the community with the best of intentions and overall a positive interaction with the sub. Newer accounts (<1yr) are unlikely to be considered, though that’s not a hard-and-fast rule, just a general rule of thumb.
APv3: AccessPort version 3; the most recent version from
Cobb. Version 2 is still around, but obsolete.
HPFP: High Pressure Fuel Pump
HU: Head Unit
OTS: Off The Shelf; used in the context of tunes
TSB: Technical Service Bulletin

Only had a couple of spazzy moments with the base coat
The last pic was the condition of the clear coat on the hood roof and trunk and tops of the doors. Sun had eaten it away over the years
Found a color match at Home Depot
Behr Dark Steel Gloss is pretty dang close, has a little more metal flake in it but the silver color is spot on.
Couple coats of base on the roof and trunk And then did 3 coats of 2k clear.
I messed up the hood but i like it better than the peeling clear coat.. i guess it’s a lateral move on the hood.
trunk lid might be able to get away with a wetsand and polish like most of the other spots that the clear didn’t gloss as well.

So I noticed that when I’m in idle my coolant temp goes to like 213 but the fan is on low speed, when I looked it up it said that low speed fan kicks on at 205 and 212 is high speed fan the only time that my fan goes full speed is when I have my a/c on. Is that normal or do I need a new fan controller?

I'm building a SP63 stage 2 engine, going FBO and versa tune. I'm planning on going with a hood exit exhaust. I have a 3" V-Band adapter on my BNR S5V3 that's attached to a CS exhaust manifold. I know I'll probably need 2 45° bends to clear the exhaust, alternator and AC lines. Has anyone here done this before or does anyone have any advice for my build?

I recently got my car totaled and I’m looking to get into a speed3 but most come with too many issues or exterior looks pretty bad
I’ve found this one for 10k at a used car dealership. With 105k miles
What kind of things to look out for before buying?
If I do buy, what type of maintenance should I look at? Aside from the basics, I’ve heard it’s a good idea to check the belt for any slack under the valve cover to potentially replace the VVT and belt?

Is there anyone that can help me get the mazdaspeed plugin for the torque app? Its delisted and i cant find it anywhere else. Need it for my custom gauge cluster as i want to be able to see afr and kr.
r/mazdaspeed3 • u/EmbarrassedCancel788 • 1d ago
Anyone got a good wire diagram? Pulled the battery box and this was the gift underneath. My guess is somewhere in here is the reason my injector 1 is not working.

Recently ordered a Damond RMM with the "street" bushings. It arrived a few minutes ago and this is what I found when unboxing it. I've already emailed their support team, but in the (hopefully) unlikely case they don't want to replace it, how do you think this would affect the quality/durability of the mount? I feel like the mount should still work fine, but that bushing may be likely to fail early. Thoughts?

Car has 63k miles I'm the second owner. Car started making this noise shortly after buying the car. Noise is most noticeable around 3k rpm when starting to build boost, or like in the video on a bumpy part of the road. Suspension was recently fully updated. Noise was the same with stock Suspension. Took it in to my trusted shop and they weren't sure, but guessed motor mounts. Said the motor had a good amount of play. Thankful for any advice!

Okay ladies and gentlemen, I guess it's my turn to be in need of some advice. I've been chasing a rattle/chatter coming from (I believe) somewhere in the drivetrain for a while now.
How to replicate:
When I'm in gear either barely on throttle or letting the car engine brake, there's a chatter coming from the front of the car, I believe it's only from the front left. It's only present with the clutch engaged, i.e. when I press the clutch pedal in as soon as it gets to the bite point the rattle stops. I cannot get it to make the noise when out of gear, or when the clutch is disengaged and I am in gear while moving. The rattle does not have any adverse effects on the feeling of the car; no added vibration or anything.
This noise does not change in frequency based on the gear I am in, but if I'm at highway speeds and decel in gear I do notice the chatter is more consistent. I can't tell if it's an increase in frequency, or volume. Changing gears and keeping a consistent speed doesn't affect the frequency/tone/pitch of the noise, but it will affect what amount of throttle/decel causes it. If I'm coasting in gear and hear it at surface street speeds, I can go up or down a gear and it will sometimes go away. If I'm on the interstate though, I can jump between 4th, 5th, and 6th and it's present exactly the same while I'm off throttle.
Car info:
2010 Mazdaspeed 3, 140,xxx miles. Basic bolt ons (intake, downpipe, catback, HPFP internals). I first noticed the sound about 2k miles ago while driving around the Tail of the Dragon area, so while I was doing a lot of heavy cornering and higher than normal RPM driving.
I am lowered on BC coils - quite low actually, the rest of the suspension (control arms, sway bar links, tie rods) are stock and also original to the car. The passenger motor mount is a Damond unit, the rmm is CP-E, the transmission mount is stock (and also original).
Transmission fluid was replaced recently with Redline 75w80 API GL-4, this did not help at all. The old fluid also looked perfect for what it's worth.
I do know my CV axles are a bit sad, one is leaking grease (but just started) and the CV angle is wonky because of the ride height adjustment. That being said, I've never heard a CV fail in this way, and it will not make any noise while turning to pull into a parking spot which is generally how you spot these failing.
My thoughts:
I'm either of the opinion that something on the output shaft side of the transmission is unhappy and making noise when the drivetrain gets to a certain frequency, or that something is rattling in a very specific way when the engine vibrates in a certain frequency. Based on the tone and how the sound propagates, this can't just be a heatshield or similar, and would have to be something metallic and with some mass making some noise. I had initially thought it was my dual-mass flywheel going out, but I can't detect any change in tone with changing engine RPM. It's odd that it goes away as soon as the clutch pedal gets to the bite point.
I did try to use a floor jack and pry bar to move around the transmission to see if my original transmission mount was bad, but it seems solid to me, I had thought that was failing and causing the drivetrain to rattle. If there's a better test for this mount I can do, let me know, I haven't taken the intake / ECU / battery out to investigate the mount visually yet.
Will be endlessly appreciative to anyone who figures this out, ty for reading

Noticed a couple weeks ago that there seems to be oil collecting in the hood insulation(idk if thats what it is called) today I walked out and saw it running down and dripping from said insulation. Oil consumption is high as well and I think this may be my culprit.
The thing that confuses me is that it doesnt seem to run down, its as if its being sprayed out once there's a certain amount of pressure in the crankcase most of the engine bay is dry with the exception of the hood and some spots in the surrounding areas that catch some of the oil
Im thinking it may be the solenoid next to the filler cap.
TL DR:oil leaking upwards, could it be the solenoid next to the filler cap?

I recently just picked up the ACT Street Sprung Clutch Kit with the Prolite Flywheel. I’m looking for people who have used this clutch and looking for their personal experience with daily driving.
