  1. Finally: Skyactiv 2.5 Cams

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    I've waited a long time for this. So I just bought some "Stage 2" cams for my 2.5 mazda 3 without really thinking about the repercussions (even though I knew there would be). Am I going to need larger injectors and/or a bigger fuel pump? I'm running E85 now, and as we all know E85 eats a lot...

  3. Mazda 3 Sport GT - Dash cams

    2014-2018 Mazda 3 Skyactiv Discussion
    Hi all, I recently purchased a 17' Mazda 3 Sport GT. I'm thinking of adding a dash camera however I noticed how large the rain sensor/smart brake support/radar cruise control unit is taking up the front windshield. It seems that the camera could not be mounted just under the rearview mirror...
  4. Skyactiv 2.5L Headers

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    I'm planning on getting some cams for my 3 down the line and I was told by some friends to get headers before I get cams. Does anyone know of a company that produces some quality headers for the 2.5L. I've been digging around and have seen headers for the 2.0 L, whether they are quality or not I...

  6. back-up cams mandatory after 2016?

    2014-2018 Mazda 3 Skyactiv Discussion
    Not quite sure where to post this, but... I've been reading about the NA Auto Show over last couple of days and ran across a claim (related to the Ford GT?) that the US govt will make back-up cams mandatory on all cars in US mkt after 2016. Is this correct? Here's the original article...

    Mazda 3 Parts - Buy / Sell
    I know the rules of the forum require pictures of my username with the parts, and I am not sure if there is somewhere else I can post this but before I start dismantling this engine, I was wondering if any one would be interested to begin with. Its a full engine with wiring harness and all. If...
  8. Cams? Head work?

    2010-2013 Mazda 3 Engine and Performance
    Has anybody messed with a cam regrind? Or are there any after market cams out there? (I own a 2.0L). I am going to own this car for the next 6-8 years or so while I'll pay off my HUGE student loans. I'd like to get to 200HP at the crank. (About 170 at the wheels?) 100hp per liter is a...
