How to Reach 550+ Hp on a K24 Using Precision Turbochargers and Forged Internals

by

The K24 engine, known for its robust design and versatility, is a popular choice among automotive enthusiasts looking to increase performance. By integrating Precision Turbochargers and forged internals, achieving over 550 horsepower is not only feasible but can be done with reliability and efficiency. This guide will walk you through the essential components and steps required to reach this impressive power output.

Understanding the K24 Engine

The K24 engine, part of Honda’s K-series, is a 2.4L inline-four engine that has gained a reputation for its strength and tuning potential. Its design allows for significant upgrades, making it a favorite among tuners. Here are some key features:

  • Aluminum block construction for weight savings.
  • DOHC design for efficient airflow.
  • Variable valve timing (i-VTEC) for improved performance.

Choosing the Right Turbocharger

Precision Turbochargers are well-regarded for their performance and reliability. Selecting the right turbocharger is crucial for achieving your horsepower goals. Consider the following:

  • Turbo Size: A larger turbo can produce more power but may introduce lag.
  • Compressor Efficiency: Look for a turbo with high efficiency ratings.
  • Wastegate Type: Internal vs. external wastegates can affect boost control.

Here are some recommended Precision Turbo models for the K24:

  • Precision 6266: A great balance of power and response.
  • Precision 5858: Ideal for those looking for quick spool times.
  • Precision 6766: For maximum power potential and higher RPM performance.

Upgrading Internals

To handle the increased power from the turbocharger, upgrading the engine’s internals is essential. Forged internals provide the strength needed for high horsepower applications. Here are the key components to consider:

  • Forged Pistons: Designed to withstand higher pressures and temperatures.
  • Forged Connecting Rods: Stronger than stock rods, reducing the risk of failure.
  • Upgraded Crankshaft: A forged crankshaft can handle the added stress.

When selecting forged internals, consider these reputable brands:

  • Wiseco: Known for high-performance forged pistons.
  • Eagle: Offers strong forged connecting rods.
  • Manley: Provides high-quality forged crankshafts.

Fuel System Upgrades

To support increased horsepower, upgrading the fuel system is critical. A proper fuel delivery system ensures that the engine receives the necessary fuel for optimal performance. Key upgrades include:

  • High-Flow Fuel Injectors: Necessary for increased fuel delivery.
  • Upgraded Fuel Pump: Ensures adequate fuel pressure under boost.
  • Fuel Pressure Regulator: Maintains consistent fuel pressure.

Consider these components for your fuel system upgrade:

  • Injector Dynamics: High-performance fuel injectors.
  • AEM: Offers reliable high-flow fuel pumps.
  • Radium Engineering: Known for quality fuel pressure regulators.

Engine Management System

To maximize the performance of your K24, an effective engine management system (EMS) is essential. A good EMS will allow for precise tuning and control of engine parameters. Consider the following:

  • Tuning Software: Choose software compatible with your EMS for optimal tuning.
  • Wideband O2 Sensor: Essential for accurate air-fuel ratio readings.
  • Data Logging: Helps monitor engine performance and make adjustments.

Here are some popular EMS options for K24 tuning:

  • Hondata K-Pro: A popular choice for K-series engines.
  • MoTeC: Offers advanced tuning capabilities.
  • AEM Infinity: Known for its flexibility and performance.

Supporting Modifications

In addition to the main upgrades, consider these supporting modifications to enhance overall performance:

  • Upgraded Intercooler: Reduces intake temperatures for better performance.
  • Exhaust System: A high-flow exhaust system improves turbo efficiency.
  • Better Cooling: Upgraded radiators and oil coolers help manage heat.

Conclusion

Reaching 550+ horsepower on a K24 engine using Precision Turbochargers and forged internals is an achievable goal with the right components and tuning. By carefully selecting your turbocharger, upgrading internals, enhancing the fuel system, and utilizing an effective engine management system, you can unlock the full potential of your K24. Remember to consider supporting modifications to ensure reliability and performance. Happy tuning!
