CAS Disc 54mm 12-1


Categories: ,


Turn your Nissan CAS into a more Speeduino friendly layout with our CAS Disk! This replaces the four-window disc with a 12-1 wheel (configured as 12-1 crank speed). We then added an external slot to provide cam synchronization, where the 360 degree slot ring works. Therefore you can use only the 12-1 inner ring to get fast synchronization and allow semi-sequential injection or individual coils. It is intended for use in the following Nissan engines, in alphabetical order:

-L28ET (1982 to 1983; earlier L28s used a variable reluctor sensor)
-KA24E (please check before ordering, some KA24E may use 50mm)

These may also directly fit other Nissan, Mitsubishi and Suzuki applications. Look for a 54mm outside diameter with a D-shaped hole in the center. Distributor-equipped engines can get additional resolution and more precise timing, while single-coil cars can now use Speeduino without having to add a tone wheel.
Easy bolt-on installation, simply remove the cover from your CAS or distributor, remove the rotor from the distributor and unscrew the large Philips screw in the middle.
