If you want to optimize the performance gains that your Mazda 323 engine is capable of, we think it's a good idea to check into installing a set of Mazda 323 cam gears. We've seen some decent power increases with stock cams and adjustable gears in some applications, so installing them on even a mildly worked engine can definitely provide some benefit with proper tuning. Adjusting your cam timing with Mazda 323 cam gears will give you the means to adjust valve overlap, giving you the most efficient combustion charge possible for your vehicle.

Cam gears allow you to make changes in your Mazda 323 engine's intake and exhaust camshaft timing, giving you control over when the intake and exhaust valves open and close, which also allows for some powerband adjustment. Keep in mind that adjusting your camshaft timing can have an effect on your air/fuel ratio, so we recommend checking your ratio after installing Mazda 323 cam gears for best results and to keep your engine in good working order.

Q: Do cam gears come individually?
A: Cam gears are sold individually unless otherwise noted. Depending on whether your vehicle is a single overhead cam (SOHC) or a dual overhead cam (DOHC), you will need one or two cam gears.

Q: What do cam gears do? Why buy cam gears?
A: Cam gears are used by many for a reliable, precise and affordable method of fine-tuning the action of the valves. This complements the installation of performance add-ons such as headers, camshafts, intakes or specialty milling work on built motors. Cam gears are often used for adjusting the timing degree of newly installed camshafts in your motor. You want to adjust cam timing to make the maximum power with your motor. If you buy aftermarket cam shafts, you cannot fine tune them to make more power if you don't have a set of adjustable cam gears.

Q: How do you install cam gears?
A: Installation should be left to the pros on this one since timing will be involved. If you plan on doing it yourself, removal of the upper timing belt cover will need to be done to reveal the cam gears. The valve cover along with the camshafts will need to be removed. Once this is done, replace the factory cam gears with your new ones and reinstall onto your camshaft. Make sure when you remove and reinstall the camshafts and cam gears they are at top dead center (TDC). Replace everything as you removed them and re-time your vehicle.
