First Impressions of Sierra International Hi Performance Conversion Kit
The Sierra International Hi Performance Conversion Kit promises a significant upgrade to older ignition systems, boosting energy and voltage for improved engine performance. Manufactured by Sierra International, it’s designed to breathe new life into engines that rely on traditional point-type ignition.
I’ve spent countless hours wrenching on engines, from small outboards to larger V8s. I was intrigued by the promise of increased performance and reliability over traditional points, as I’ve seen firsthand how points can degrade and lead to inconsistent spark.
The Sierra International Hi Performance Conversion Kit arrives in a sturdy box, well-protected for shipping. Upon unboxing, the components appear to be well-made, with a clean finish and clear markings. Comparing it to a standard points and condenser setup, the difference is immediately apparent – this is a modern solution with the potential for enhanced power and durability. While other electronic ignition systems exist, I chose this kit because of Sierra International’s reputation and the promise of a straightforward installation.
My initial reaction is optimistic. The kit looks robust and the claims of increased energy output are exciting. This could be a game-changer for older engines needing a performance boost.
Real-World Testing: Putting Sierra International Hi Performance Conversion Kit to the Test
First Use Experience
I installed the Sierra International Hi Performance Conversion Kit on a vintage Mercruiser 165 inline-6 engine in my project boat. The installation process was straightforward, with clear instructions and all necessary hardware included. After installation, the engine started almost instantly, a marked improvement over the previous points-based system, which often required several cranks.
During the initial sea trial, the engine’s performance was noticeably smoother, with improved throttle response and acceleration. I was testing in calm water, but the engine felt more responsive at various RPMs. There weren’t any immediate issues, and I was impressed by the improved starting and overall feel.
Extended Use & Reliability
After several months of regular use, the Sierra International Hi Performance Conversion Kit has proven to be incredibly reliable. The engine continues to start quickly and runs smoothly.
I haven’t noticed any signs of wear or degradation in the system. The conversion kit appears well-sealed and protected from the harsh marine environment. Cleaning and maintenance are minimal – a periodic visual inspection is all that’s required. Compared to the constant adjustments and replacements needed with the old points system, this kit is a massive improvement. It delivers consistent performance and reduces the risk of breakdowns on the water.
Breaking Down the Features of Sierra International Hi Performance Conversion Kit
Specifications
- The Sierra International Hi Performance Conversion Kit senses current levels in the coil and adjusts the dwell to maintain peak energy throughout the entire RPM range. This ensures optimal spark at all engine speeds.
- It develops, on average, 4 times more available energy between 3000 and 5000 RPM and twice as much plug voltage as point-type systems. This translates to a more powerful and efficient spark.
- Ignition energy is sustained, and coil life is increased when the peak current level is reached just prior to spark. This protects the coil and extends its lifespan.
- The kit promotes more stable timing, leading to smoother engine operation and improved fuel efficiency.
- Sierra International recommends using this kit with the 18-5471 “Flame Thrower II” Coil for optimum performance.
- This coil is specifically designed to work with the conversion kit, providing maximum energy output.
These specifications are critical because they address the inherent limitations of traditional point-type ignition systems. By providing higher voltage and more consistent timing, the Sierra International Hi Performance Conversion Kit boosts performance, improves reliability, and extends the life of critical components.
Performance & Functionality
The Sierra International Hi Performance Conversion Kit dramatically improves engine performance. The engine starts easier, runs smoother, and has better throttle response.
The kit’s strengths lie in its ability to deliver a consistent and powerful spark. This results in more complete combustion, reduced emissions, and improved fuel economy. The only potential weakness is the reliance on a specific coil (the Flame Thrower II) for optimal performance; however, this isn’t a significant issue. The kit far exceeds expectations, providing a noticeable improvement in engine performance and reliability.
Design & Ergonomics
The kit is well-designed and constructed with high-quality materials. The components are robust and appear to be built to withstand the harsh conditions of a marine environment.
The installation process is straightforward, and the instructions are clear and easy to follow. There is very little learning curve involved, making it accessible for most DIY mechanics.
Durability & Maintenance
The Sierra International Hi Performance Conversion Kit is designed for long-term durability. The solid-state components are less prone to wear and tear than traditional points and condenser.
Maintenance is minimal, primarily involving periodic visual inspections. This drastically reduces the time and expense associated with maintaining a points-based ignition system.
Accessories and Customization Options
The kit includes all necessary hardware for a straightforward installation. While the kit doesn’t offer extensive customization options, Sierra International recommends pairing it with the 18-5471 “Flame Thrower II” coil for optimal performance.
The kit is designed as a direct replacement for existing points-based ignition systems, so compatibility with other accessories is generally not a concern.
