  1. 2006 Mazda 3 2.0L starting issue

    2019+ Mazda 3 How-To Guides
    So my wife drives a 2006 Mazda 3 2.0L manual. Been having a problem when she starts it, it'll do the typical engine revving sounds etc like it's trying to start but will not start the first time. She'll put the key back to the off position and try again and it'll start the second time but...
  2. Oil Pan 2.0L to 2.3L

    2004-2009 Mazda3 Discussion
    I have a 2007 non turbo 2.3L engine and I was curious if a Oil Pan from a 2.0L will fit on my car? It seems all the bolt holes match up. Would like to know before I drop the broken pan and try to replace TIA
  3. Pennzoil Synthetic - 0w20 for 2.0L

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    Hi folks, I've been doing 7,000k mile OCI's on the wife's 2.0L motor and to be frank, I have been using Pennzoil's 0w20 synthetic because it's dirt cheap with their commonly offered rebates (probably ends up being a $15 jug for a 5L bottle). Project farm on youtube also shows it as favorable...

  5. 2014 2.0l Intake VS 2015-2018

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    Good evening all, I was doing some browsing tonight and checking out some cold air intakes. I'm not here to debate their effectiveness, but instead looking for some clarification. Specifically, AEM intakes, model 21-773C (aemintakes.com/search/product.aspx?prod=21-773c). It's a short ram...
  6. Help! 2006 Mazda 3 2.0L

    2004-2009 Mazda3 Discussion
    What is the hole on the cylinder head that is between the #2 and #3 spark plug tubes? It is threaded. I noticed some coolant on the two ignition coils. Could it be coming from this hole?

  8. 2006 Mazda 3 2.0l needs new engine. LOOKING TO BUY

    2010-2013 Mazda 3 Engine and Performance
    Hey everyone! Very new to this forum but I've had my Mazda 3 for 2 years. Well a month ago it jumped time and bent cylinder components. I got quoted a crazy price for a new engine. I have money so I was hoping someone on here has a good running engine ready to sell. We have a trailer to come...

    2004-2009 Mazda 3 Performance & Mods
    I am in the market for a turbo charger for my 2.0L 2008 mazda 3. How should I go about doing this? What brands, how much should I spend, bolt on or no? How much boost is safe for stock engine parts, etc. I would like horsepower comparable to mps/speed3's if possible. Thanks.

    2010-2013 Mazda 3 Engine and Performance
    Hi, new Mazda owner (kind of) my wife bought a new Mazda 3 sedan in 2012 and drove 30000 miles on it. Come years later we need an SUV for the kids, so I just sold my car (2015 Scion TC) and got her a 2019 Santa Fe. I am taking over the Mazda 3 and I figured I would put $1,500 into it to make it...

    2010-2013 Mazda 3 & Skyactiv Discussion
    Hey guys so recently as of yesterday my CEL came on in my 2016 3 at 31,000. I checked the code and it was P0171 running too lean. I checked to see what the possible causes were and from what I've read there's a lot, MAF, MAP, PCV, fuel injectors, ect. So just to narrow down my search. What...

    So theres this youtube video: https://youtu.be/SuexiG4aYR4 Its a 2011 M3 2.0L, they put on a Corksport catback system with a racepipe. I love that sound and how loud it is. I see that Corksport doesnt offer a racepipe for the 2015 M3. I am wondering if its possible to buy the catback for the...
  14. Best 2.0l performance upgrades

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    I've got a leased 2016 manual 2.0l that I'll be buying out in the next few months. I also happen to have some extra cash laying around, so I think it's time to make this baby faster. I'm thinking lowering springs+SRI+exhaust+plus ECU tune. What would you guys do? I have around $2k budget but I...

  17. Testing out muffler delete on 2.0L

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    I know muffler deletes are relatively controversial in the car community (as are most things lets be honest), but i tried it anyways because to get a y-pipe is hundreds of dollars cheaper than an aftermarket exhaust. Here is a video of the process me and my friend went through to test it as well...

    My current M3 is a 2014 2.0L 4Dr as the title says, and it's my first car. I currently have 50k miles as I bought the car used and I'm wanting to replace the rotors and pads.

  20. Best 0-200km 2.0L & 2.5L?

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    So yes, I think it is time to check and discuss what is the best time some of us have recorded 0-200km , I mean of course totally irrelevant since these cars are not performance machines but we wished!, let's not deny that 0:) So here is the back story, I was speeding with this 1.8L...
