    So awhile ago i was messing around with some buddies. Dumped the clutch spun the tires a bit and there was a really quiet pop and then the transmission stopped engaging. I lost all gears including reverse, shifts into gear but doesn’t grab so it just revs. I noticed my passenger side drive shaft...

    Hey guys, picked up a Mazdaspeed 3 not too long ago and the first thing I did was a VTCS delete. I read that doing a VTCS delete might make the car throw a P0421... What's the solution to this? Is it getting a 02 sensor extension?
  3. MazdaSpeed3 Brakes and Suspension
    (New to the forums) So I have an '07 Mazdaspeed 3 that I've owned for almost 3 years now and have been modifying it since. I took a trip to Gatlinburg, Tennessee at the beginning of October since I was in a show down there called slammedenuff. It was a 12 hour trip each way from Wisconsin and...

    Hello all! I'm new to this forum, but not to forums in general. I used to really be into the 1st gen Lexus IS scene, but I got out because you can't tune a stock toyota ECU 😐. As a 6ft 2 dude, I'm looking into a 1st gen MS3, but there are still some uncertainties I keep reminding myself about...

    A couple days ago I bought a Mazdaspeed3. It’s got 91k miles. However, I noticed today when I turn the car off there is immediately a squeak that follows it as the engine is settling. It’s coming from the belt area. The serpentine belt looks slightly dry rotted. The other belt looks almost brand...
  7. MazdaSpeed3 DISI Turbo
    History: I have a cold air intake, blow off valve, and basic Cobb Partial Stage 1-af tune. Screwed my first engine and had it replaced with a DISI from a CX7 with 40k miles on it. I had all my original parts moved to it, including my bigger turbo. Replaced the spark plugs. Cleaned the EGR...

Someone else should buy and love this beast the way it's meant to be loved. Miles: ~91.5k Location: Cary, NC There are a few things that...
  9. I Just Got my Mazda3/MazdaSpeed3!
    Please help me just looked at a 2010 Mazdaspeed 3 for sale which seemed to be an absolute steal at first however during the inspection I found a small amount of froth on the filler cap (which could be short journey as the current owner only drove 6,000 miles in the last year) high amounts of oil...
  10. MazdaSpeed3 Modifications
    So I have a 2010 speed 3, and from my research, it seems like you want to buy a bypass valve instead of a bov. I would really like one that sounds good. I already got an intake but i think a bypass valve would help complete the sound. there are a lot of bypass valves out there and i would...

  14. MazdaSpeed3 Modifications
    Hey there, so I just recently got a 1st gen ms3 and it either needs a rebuild or new engine. The previous owner ran out of oil when driving and now there’s knocking. I’m wondering if I should engine swap or just rebuild. And if I engine swap, what should I get? Or should I just rebuild. Let me know.

  16. MazdaSpeed3 Stock Issues
    Took my 2010 ms3 w/ 60k miles to the dealer due to a clicking sound when the car moves from a stop, and transmission whine. They drained the transmission fluid and are telling me I need a new trans since they found a fair amount of metal shavings. I did some research and it sounds like its...

    Hey there, I’m having a problem with my 2008 Speed 3. When I’m travelling along the highway with cruise control on and I go on a slight incline, the engine begins to burble/misfire after that slight load is introduced. It doesn’t seem to do it under full boost conditions. Only just at low rpms...

    I’m hearing a pretty large rattling sound from the timing chain and a rattling/tapping sound at idle, I’m assuming this means my timing chain needs to be rebuilt? Any help is great thanks guys
