    Hi Everyone, I am looking for a solution to change the gear ratio in my 2005 2.3 Mazda 3, particularly for the last gear to make it more of an overdrive.

    Hey all, Anyone have an idea as to why I get this annoying squeal accelerating in low gear around 1.75 - 2.25 rpm? Sorry if it's hard to hear it on the noisy road.
  8. RPM Question

    Engine / Drivetrain
    I have gotten into the habit of driving in first gear and reeving often up to 5k plus. Is this bad for the engine and I should stop doing it? How much can a engine handle and not affect life of the engine and such? Is there a difference in affect on the engine if your high RPM in lower gears...

    2004-2009 Mazda3 Discussion
    My wife's 05 3 has about 105k miles on it and we just changed the plugs and did an oil change. Afterwards it's been having a strange RPM bouncing issue. It only happens in 4th gear around 1000rpm. It'll go up to 1500 then back down to 1000 a few times then stop. It will do this anywhere from 2...

  13. Rattle under load @ low RPM (possible culprit identified)

    2014-2018 Mazda 3 Skyactiv Discussion
    It's a 2015 Mazda 3 hatch. So, there is a rattle that is present under load at lower RPM. It sounds like it's metal to metal (e.g. loose nut) and location is very hard to pinpoint, sometimes looks like it's from the rear, sometimes from the front. Anyways, I noticed that the rear bumper rings...

  15. Maximum RPM's in 6th Gear

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    Just wondering about my 6 speed manual 2.5. In 6th gear I am at 2000 rpm's at 55mph. So I would assume I would be going 110mph at 4000 rpm's. and 138 at 5000 rpm's. Question is where will the tach top out at in 6th gear. Would it ever get to 5000 rpm's?
  16. Disable rpm holding on manual transmission?

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    I have a 2014 Mazda3 iTouring 6MT I recently got a BMW and the first thing I noticed in comparison to the Mazda3 is that the Mazda3 holds the RPM for a long time, making it hard to do quick shifts smoothly especially going from 1-2. There were reports if the shift indicator goes out, for...

    Ok, so I've decided to lose 150kms a year on my odometer and go with a 225/35-18 front tires to add pep to the car. Question is, shift points changes and rpms and speedometer changes especially on 6th gear on an AT. 811 rev/mile stock vs 833 rev/mile new tires. Any takers on this one?

  19. Engine braking causes RPM fluctuations

    2014-2018 Mazda 3 Skyactiv Discussion
    I have an automatic sGT. When I'm coasting down a gentle slope in heavy traffic, I like to manually downshift to 2nd gear to control my speed and ease my braking. When doing so I've noticed that my RPM will steadily rise to 2000, then suddenly drop down to 1000, then steadily rise back up to...
  20. 2.5L RPM - Best Noise

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    So lately on my boring traffic filled commutes I've been fooling around with my car in manual mode, trying to find two things ... 1 - the power band and 2 - the best gear / RPM combo to get the best 2.5L deep growl noise - unless I'm the only one who notices this? 1 - 2nd gear around 2500 - 4k...
