    Looking for just the pulley (not the whole dang $250 assembly!!!) to the top idler (sits at the top of the engine on the 2.5L; 2010 Mazda 3 S). Can't even find the bearing for it (NSK 6303DU1LB). Anyone? Googlel search GATES 36422 and you will see what I am referring to. Thanks!
  2. Corksport lightweight pulley?

    2014-2018 Mazda 3 Skyactiv Discussion
    Hey all, it's been a while. Been really busy, but I'm going to start throwing some more mods at my car. Just ordered the RMM and looking forward to a more raw feel. There are two parts I'm eyeing at the moment; the CS Pulley, and the transmission mount. Does anyone have any experience with...

    2010-2013 Mazda 3 & Skyactiv Audio & Electronics
    I have a 2010 Mazda 3 S (NA - no mods). Some serious pulley bearing noise from the tensioner pulley. I get conflicting part numbers for that guy and was wondering what folks have used for this application? And actually, the tensioner itself has plenty of life still left in it -- it's the...

  7. Unortodox Racing Crank Pulley

    2010-2013 Mazda 3 Engine and Performance
    Since there doesn't seem to be a light weight crank pulley coming out for the 2.5L engine any time soon I went ahead contacted Unorthodox racing to see if I could put something together for us. This is the email I got back from them: The Mazda 3/6 crank pulley requires an intricate installation...
  8. Crank Pulley, Pulley Set or Underdrive?

    2010-2013 Mazda 3 Engine and Performance
    omfg it's jeremy just pm'd me asking about whether we were going to do underdrive pulleys. Right now, we offer a lightweight crank pulley for the early BP powered Protege's, etc. Here's a link to one for an example: CORKSPORT Lightweight Pulley For Mazda 1.6/1.8 DOHC The 2010 is a little...
