Ultimate Ignition Upgrade for FC RX-7
The Elite 1500 + Mazda 13B S4/5 CAS with IGN-1A Ignition Harness Kit is the ultimate solution for FC RX-7 owners seeking modern reliability and massive spark energy. Designed for the Series 4 and 5 13B engines, this kit integrates the Haltech Elite 1500 ECU with a harness specifically terminated for IGN-1A Smart Coils. This eliminates the weak factory coils and igniter, providing the spark needed for high-boost applications.
Engineering Breakdown
The harness connects directly to the S4/5 Crank Angle Sensor, ensuring precise timing input. It routes high-current power and logic triggers to the IGN-1A coils, which are capable of delivering over 100mJ of spark energy. The harness also features Bosch EV1 injector connectors, making it compatible with standard high-performance injectors. This is a complete “engine management in a box” solution for the ignition and fuel side of an FC build.
