Convert your Nissan CAS to a more MegaSquirt-friendly arrangement with our bolt in optical shutter wheel!
This one replaces the ring of four slits with a 24-1-1 wheel that behaves like a 12-1 crank trigger. Then we added an outside slot to provide a cam sync where the 360 degree slot ring works. So you can use just the inner ring to get a rapid sync-up, or use the outer slot to allow for sequential injection or coil-on-plug. This is intended for use on the following Nissan motors, in alphabetical order.
- L28ET (1982 to 1983; earlier L28s used a variable reluctor sensor)
- KA24E (please check before ordering; some KA24Es may have used a 50 mm)
It may also fit other Nissan, Mitsubishi, and Subaru applications. Look for a 54 mm outer diameter with a D-shaped hole in the center. Distributor equipped engines can gain extra resolution and more precise timing, while cars with coil on plug can now use MegaSquirt without having to add a crank trigger. Easy bolt on installation, just take the cover off your CAS or distributor, remove the rotor on a distributor, and undo the big Philips screw in the middle. Once you’ve got that, it just drops in.
