Optimize your engine’s power, torque, and reliability and eliminate the factory CAS with our SR20VE trigger kit. Uses 2x 3 wire hall effect sensors. The main trigger plate mounts between your flywheel and crankshaft and the front trigger is driven off the inlet camshaft. The camshaft sensor mount goes in place of the front frost plug so there is no drilling or tapping required. Just knock out the frost plug and the adapter goes in its place! This kit comes with everything you will need as well as the CAS delete plate. Aftermarket ECU must be used with this kit.
