When it comes to upgrading the turbocharger on your Mitsubishi Lancer Evolution 7 (Evo 7), choosing the right size turbo can significantly impact performance. Among the popular options are the 16G and 18G turbos, each offering unique characteristics and power gains. This article will explore the differences between the two turbos and help you make an informed decision.
Understanding Turbocharger Sizes
Turbochargers are classified based on their size, which affects their airflow capacity and boost levels. The size of a turbocharger influences how quickly it can spool up and how much power it can produce. In the case of the Evo 7, both the 16G and 18G turbos are popular choices among enthusiasts.
16G Turbocharger
The 16G turbocharger is a well-known option for the Evo 7, offering a good balance between performance and reliability. It is often considered a great starting point for those looking to enhance their vehicle’s power without going overboard.
Power Gains
With the 16G turbo, you can expect significant power gains over the stock turbo. Typical gains can range from 50 to 100 horsepower, depending on supporting modifications such as exhaust systems, intercoolers, and tuning.
Spool Time
One of the advantages of the 16G turbo is its relatively quick spool time. This means that drivers can experience boost at lower RPMs, leading to improved throttle response and overall drivability.
Reliability
The 16G turbo is known for its reliability, making it a popular choice for daily drivers. With proper maintenance and tuning, it can provide consistent performance without the risk of premature failure.
18G Turbocharger
The 18G turbocharger is a step up from the 16G, designed for those seeking higher power levels and performance. It is often favored by enthusiasts looking to push their Evo 7 to the limits.
Power Gains
When upgrading to an 18G turbo, power gains can be even more impressive. Depending on supporting modifications, drivers can see gains of 100 to 150 horsepower over the stock setup, making it a compelling option for serious performance seekers.
Spool Time
While the 18G turbo offers higher power potential, it typically has a slightly slower spool time compared to the 16G. This means that drivers may experience a delay in boost delivery, especially at lower RPMs.
Reliability
Although the 18G can provide substantial power, it may require more careful tuning and maintenance to ensure reliability. Drivers should be aware of the increased strain on the engine and associated components.
Comparison of 16G vs 18G Turbochargers
To better understand the differences between the 16G and 18G turbos, let’s compare their key characteristics.
- Power Gains: 16G offers 50-100 hp; 18G offers 100-150 hp.
- Spool Time: 16G has quicker spool; 18G has slightly slower spool.
- Reliability: 16G is generally more reliable; 18G requires careful tuning.
Factors to Consider When Choosing a Turbo
When deciding between the 16G and 18G turbos, several factors should be considered to ensure the best fit for your driving style and goals.
- Driving Style: Consider how you plan to use your Evo 7. If you want a daily driver with quick response, the 16G may be more suitable.
- Performance Goals: If your goal is maximum horsepower and track performance, the 18G could be the better choice.
- Budget: Factor in the cost of the turbo, installation, and any necessary supporting modifications.
- Supporting Mods: Ensure your vehicle has the necessary modifications to support the chosen turbo for optimal performance.
Conclusion
Choosing the right size turbo for your Evo 7 is crucial for achieving your desired performance. Both the 16G and 18G turbos offer unique advantages and power gains. By considering your driving style, performance goals, and budget, you can make an informed decision that aligns with your automotive aspirations.
