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:
-KA24E (Note: Some KA24E use a 54mm drive – please check before ordering.)
-SR20DE (Note: Some FWD applications used a 54mm drive – please check before ordering.)
-SR20DET (Note: Some FWD applications used a 54mm drive – please check before ordering. All RWD versions are believed to be 50mm.)
These may also directly fit other Nissan, Mitsubishi and Suzuki applications. Look for a 50mm outside diameter with a D-shaped hole in the center. Will not fit most RB, VG or CA motors. 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.
