by

The choice between 68mm and 72mm K-series turbo sizes is crucial for performance enthusiasts looking to maximize power. Understanding the differences in these turbo sizes can greatly influence your vehicle’s performance and efficiency.

Understanding Turbo Sizes

Turbochargers are essential components in enhancing engine performance. The size of the turbo affects the amount of air it can compress, which directly influences the power output of the engine. Here, we will explore the key aspects of 68mm and 72mm K-series turbos.

68mm K-Series Turbo

The 68mm K-series turbo is known for its quick spool time and responsiveness. This makes it an excellent choice for drivers who prioritize acceleration and low-end torque.

Advantages of 68mm Turbo

  • Faster spool time for improved throttle response.
  • Better suited for street applications and daily driving.
  • Lower lag, making it ideal for low RPM power delivery.

Disadvantages of 68mm Turbo

  • May not provide maximum power at higher RPMs compared to larger turbos.
  • Limited potential for extreme horsepower builds.

72mm K-Series Turbo

The 72mm K-series turbo offers a larger compressor wheel, which allows for greater airflow and higher power potential. This turbo is favored by those looking to push their engines to the limits.

Advantages of 72mm Turbo

  • Higher power output potential at higher RPMs.
  • Better for racing and performance applications requiring maximum horsepower.
  • Improved efficiency at high boost levels.

Disadvantages of 72mm Turbo

  • Longer spool time, which can affect throttle response.
  • Increased lag, making it less ideal for daily driving.

Choosing the Right Turbo Size

When deciding between a 68mm and a 72mm K-series turbo, consider your driving style and performance goals. Here are some factors to keep in mind:

  • Driving Style: If you prefer quick acceleration and responsive handling, the 68mm turbo may be the better option.
  • Performance Goals: For maximum horsepower and racing applications, the 72mm turbo is more suitable.
  • Vehicle Setup: Ensure that your vehicle’s engine and supporting mods can handle the turbo size you choose.

Conclusion

Ultimately, the choice between a 68mm and 72mm K-series turbo comes down to your specific needs and performance objectives. Both turbos have their strengths and weaknesses, making it essential to assess your priorities before making a decision.
