When it comes to upgrading the turbo on your Duramax engine, selecting the right size and brand is crucial for optimizing performance. Two popular sizes for turbo upgrades are 64mm and 66mm, with leading brands including Garrett, BorgWarner, and Turbonetics. This article will explore the differences between these turbo sizes and brands to help you make an informed decision.
Understanding Turbo Sizes
The size of a turbocharger significantly impacts its performance characteristics. In general, a larger turbo can provide more airflow, which can lead to increased power. However, this can also result in turbo lag, which is the delay before the turbo begins to boost power. Here, we will discuss the characteristics of both 64mm and 66mm turbos.
64mm Turbos
64mm turbos are a popular choice for those looking to improve their Duramax’s performance without sacrificing too much drivability. These turbos typically offer a good balance between spool time and power output.
- Spool Time: Faster spool time compared to larger turbos.
- Power Output: Can support up to 600-700 horsepower depending on supporting modifications.
- Drivability: Maintains good throttle response for daily driving.
66mm Turbos
66mm turbos are designed for those who want to push their Duramax to higher power levels. While they can provide greater airflow and power potential, they may introduce more turbo lag.
- Spool Time: Slightly slower spool time than 64mm turbos.
- Power Output: Can support 700-900 horsepower with proper modifications.
- Drivability: May require tuning for optimal performance and drivability.
