    Hey guys, I have been selling cam gears with a 2nd keyway cut into them. The 2nd keyway has a 3° retarded keyway cut in it. These work with the 1GRFE (V6) engine. Tuning to maximize the gains associated with this mod is recommended but not necessary. (just like an intake or exhaust)

    Current price is $100 for the machining of both gears and includes the return shipping nation wide. This is if you are providing me with the gears.

    For $150 I will provide gears for you. Less work for you and faster turn around as I plan to have a couple in stock. The extra 50 is the cost of OEM gears with little to no mark up.

    If you are active military or a veteran- 10$ off.

    PM me directly when you're ready to place an order.

    OEM part # 13523-AD010
    Cloyes part # S960T
    Napa part # NTP S960T
    They don't come in sets so make sure to purchase two if going this route

    For those wonder what exactly these do.
    "The exhaust cam gears retard the exhaust gear timing by 3° in relation to crank angle. Allowing the cylinders to empty more completely on the exhaust stroke. On the intake stroke the cylinders will fill with more air and fuel increasing the overall volumetric efficiency of the engine. There will also be less hot exhaust gas left heating the incoming air and fuel and reducing it's knock potential. This is very advantageous with forced induction conversions." -URD

    Myself and many others are now running these gears with great success. It increased my mileage and has notably more power in the mid rpm range. Plus the engine just runs happier.

    Here is an install video.
    https://youtu.be/YmwXtpukhFU


    Here is a link for valve cover removal instructions.
    http://www.toyota120.com/forum/showthread.php?p=186857


    here is the pdf install instructions from URD
    https://www.tacomaworld.com/attachments/urd-1gr-cam-gear-installation-v-1-1-draft-pdf.3283622/

    Instead of taking the time to put a timing mark in relation to the new keyway that is 3° off, what I do is only bevel the new keyway on the back side so that it is clear which keyway is the one I made and to show which way should be facing front. When installing the gear, if you can only see one bevel, then it is facing the correct way. (see below) 3° keyway at bottom
    front.jpg
    "F" for front. Gears sent out wont have this "F" so bevel observation will be required. I recommend drawing with a marker or whiteout etc. a line to the tooth that is most closely aligns to. This will aid with install.




    back.jpg
    This is the back of the gear. The side that will face the engine. Here you can see the bevel I did which also aids with install as I'm keeping tolerances as tight as possible.




    stock gear.jpg
    Here is the stock gear with the keyway facing up (yellow arrows). If you look closely at the chain itself, you can see a link on the backside that is painted orange from the factory (under blue arrow). The orange chain link is from the factory and wont align perfectly with the keyway with every turn of the crank so you might have to turn the engine over by hand a few times to get this orientation. Once in this orientation, the chain is already marked for you for which link the newly marked keyway/tooth will go into.




    my gear.jpg
    Here is the re-machined gear installed. 2nd bevel not visible so its in correct orientation. You can see that the new keyway and its closet aligned tooth is right back in on the orange link (marked in red here) After you get this done on both engine banks- you're done and can start re-assembly.

    +1 can't wait to receive mine. Be mindful when ordering your own gears, it will take time. It seems we've exhausted some sources of gears from different vendors already with just our small run of 30 orders.

    Any dyno testing to see what kind of numbers these things will add? Seems like a cool product.

    A cam gear only before and after dyno test has never been performed to my knowledge. @Torspd have you seen or heard if its been done? Urd has them in the kits they sell and they have full bolt (including these) dynos vs before numbers. Only numbers I can speak to are improved gas mileage, improved "butt dyno" and better driveability.

    You also have a datalog of better knock threshold. Which allows more timing. Which makes more HP.

    There are no dyno's yet, with just a cam gear install. Only your datalogs.
