About Optical Trigger Wheel For Nissan SR20DET Or KA24DE

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. Intended for use with MS1 and MS2 (MS3 has experimental support for the stock CAS). This is intended for use on the following Nissan motors, in alphabetical order. GA16DE KA24E KA24DE SR20DE SR20DET It may also fit other Nissan, Mitsubishi, and Suzuki applications. Look for a 50 mm outer diameter with a D-shaped hole in the center. Does not fit most RBs, VG, or CA motors. 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.
