Power gets to a 300ZX coil through the ignition system, which includes the ignition switch, ignition relay, and wiring harness. When the ignition key is turned, power flows from the battery through the ignition switch to the ignition relay, which then sends voltage to the coil. The engine control unit (ECU) also plays a role by controlling the timing of the spark, allowing the coil to generate a high-voltage spark needed to ignite the fuel-air mixture in the engine's cylinders.
Yes, an LS3 engine can fit in a 1984-1989 Nissan 300ZX, but it requires significant modifications. This includes custom engine mounts, a compatible transmission, and adjustments to the exhaust and cooling systems. Additionally, modifications to the wiring harness and potentially the fuel system may be necessary. Overall, while the swap is feasible, it involves considerable effort and expertise.
