The Toyota 86 is known for its lightweight design and engaging driving experience. However, enthusiasts often seek ways to enhance performance and reliability. One such upgrade is the transition from traditional distributor-based ignition systems to coil-on-plug (COP) ignition systems. This article explores the real-world results of upgrading to COP systems in the Toyota 86.
Understanding Coil-On-Plug Ignition Systems
Coil-on-plug ignition systems eliminate the need for ignition wires by placing an individual coil directly on each spark plug. This design improves ignition timing accuracy and enhances the overall efficiency of the ignition process.
Advantages of COP Systems
- Improved ignition timing accuracy
- Reduced electrical resistance
- Better fuel efficiency
- Enhanced engine performance
- Lower emissions
Real-World Performance Enhancements
Upgrading to a COP system can lead to noticeable improvements in various performance metrics. Owners of the Toyota 86 have reported several key benefits after making this switch.
Throttle Response
Many drivers have noted a significant improvement in throttle response. The direct connection between the ignition coil and spark plug allows for quicker and more efficient firing, leading to a more responsive driving experience.
Power Output
Dyno tests conducted on upgraded Toyota 86 vehicles show an increase in power output. Drivers have reported gains of up to 10-15 horsepower, particularly in higher RPM ranges where ignition efficiency plays a crucial role.
Fuel Economy
With better combustion efficiency, many users have experienced improved fuel economy. This enhancement can lead to savings at the pump, making the investment in a COP system more appealing.
Installation Process
Installing a coil-on-plug ignition system on a Toyota 86 requires some technical knowledge and the right tools. The process generally involves the following steps:
- Gather necessary tools and parts
- Remove the engine cover and existing ignition components
- Install COP units onto each spark plug
- Connect wiring harnesses to the new coils
- Reinstall the engine cover and perform a system check
Potential Challenges
While the benefits of upgrading to a COP system are appealing, there are potential challenges to consider:
- Initial cost of parts and installation
- Compatibility issues with existing ECU
- Need for tuning after installation
Conclusion
Upgrading to a coil-on-plug ignition system on a Toyota 86 can yield significant real-world benefits, including improved throttle response, increased power output, and enhanced fuel economy. While the installation may present some challenges, the performance gains often justify the investment. For enthusiasts looking to maximize their driving experience, this upgrade is certainly worth considering.
