To achieve 400 horsepower, it is crucial to understand the engine’s architecture and how the turbo kit integrates with it.

Key Features of the K-Series Engine

  • Aluminum block and head for reduced weight
  • DOHC design for efficient airflow
  • Variable valve timing for optimal performance

The TD05H-20G Turbo Kit

The TD05H-20G turbo is a popular choice among tuners for its ability to produce significant power while maintaining reliability. This turbocharger is known for its efficiency and responsiveness, making it ideal for achieving high horsepower figures.

Specifications of the TD05H-20G Turbo

  • Compressor wheel size: 20G
  • Turbine wheel size: TD05H
  • Boost pressure: Capable of handling up to 25 PSI

Essential Components for Achieving 400 HP

To effectively use the TD05H-20G turbo kit and reach 400 horsepower, several key components must be upgraded or replaced. These components work together to ensure the engine can handle the increased power and boost levels.

Upgraded Fuel System

A high-performance fuel system is crucial when increasing horsepower. Upgrading your fuel injectors and fuel pump will provide the necessary fuel flow to support higher boost levels.

  • High-flow fuel injectors (at least 750cc recommended)
  • Upgraded fuel pump (e.g., Walbro 255lph)

Exhaust System Upgrades

A free-flowing exhaust system helps reduce back pressure and allows the turbo to spool more efficiently. Consider upgrading your downpipe and cat-back exhaust system for optimal performance.

  • 3-inch downpipe
  • High-flow catalytic converter or test pipe
  • 3-inch cat-back exhaust system

Engine Management System

Proper tuning is essential to maximize the performance of your K-series engine with the TD05H-20G turbo. An aftermarket engine management system will allow you to adjust fuel maps, ignition timing, and boost levels.

  • Hondata K-Pro or AEM Series 2
  • Wideband O2 sensor for accurate air-fuel ratio monitoring
