If you’re looking to boost the performance of your 4A-GE engine, one of the most effective modifications you can make is the installation of Tomei Poncams and a TRD intake. These components work together to significantly increase horsepower and improve engine responsiveness. In this article, we will guide you through the steps to gain over 40 horsepower with this combination.

Understanding the 4A-GE Engine

The 4A-GE engine, a beloved powerplant in the Toyota community, is known for its lightweight design and rev-happy nature. Originally designed for the AE86 Corolla, this engine has become a favorite for tuners due to its potential for high performance. To maximize its capabilities, understanding its components and how they interact is essential.

Benefits of Tomei Poncams

Tomei Poncams are aftermarket camshafts designed to enhance the performance of your engine. Here are some key benefits:

  • Increased Valve Lift: Poncams provide greater lift, allowing more air and fuel into the combustion chamber.
  • Optimized Timing: Improved timing enhances the engine’s overall efficiency and power output.
  • Better Throttle Response: The combination of lift and timing results in a snappier throttle response.

Advantages of the TRD Intake

The TRD intake is another crucial component for maximizing horsepower on the 4A-GE. Here’s why it’s a great choice:

  • Higher Airflow: The TRD intake allows for increased airflow, which is essential for combustion.
  • Improved Sound: A performance intake often results in a more aggressive engine sound, enhancing the driving experience.
  • Lightweight Design: The TRD intake is designed to reduce weight, contributing to overall performance.

Installation Process

Now that you understand the benefits of both the Tomei Poncams and TRD intake, let’s discuss the installation process. Proper installation is crucial for achieving the desired horsepower gains.

Tools Required

  • Socket set
  • Torque wrench
  • Screwdrivers
  • Camshaft timing tool
  • Gasket scraper

Step-by-Step Installation

  • Remove the Engine Cover: Start by removing the engine cover to access the camshafts.
  • Disconnect the Battery: Always disconnect the battery before working on your engine.
