Turbocharging Your Acura Integra B-Series Engine: A Comprehensive Guide

The Acura Integra, especially the B-Series engine models, has long been a favorite among car enthusiasts for its blend of performance, reliability, and affordability. For those looking to take their Integra’s performance to the next level, turbocharging presents an enticing option. By adding a turbocharger to your Integra’s B-Series engine, you can unlock a significant boost in horsepower and torque, turning your car into a formidable street or track machine.

Understanding Turbocharging

Before delving into the specifics of turbocharging your Acura Integra B-Series engine, it’s essential to understand how turbochargers work. A turbocharger is a forced induction system that compresses the air entering the engine, allowing more air and fuel to be burned, resulting in increased power output. It consists of a turbine and a compressor connected by a shaft. The exhaust gases drive the turbine, which, in turn, spins the compressor, forcing air into the intake manifold at higher pressures than atmospheric.

Benefits of Turbocharging

Turbocharging offers several benefits for enthusiasts seeking enhanced performance:

  1. Increased Power: By compressing the air entering the engine, turbocharging significantly increases the engine’s power output. This results in faster acceleration and higher top speeds.
  2. Improved Torque: Turbocharged engines typically exhibit greater torque throughout the rev range, providing better low-end grunt and mid-range performance.
  3. Efficiency: Turbocharging allows engines to extract more power from a given amount of fuel, improving overall fuel efficiency despite the increase in power output.
  4. Customizability: Turbocharger systems are highly customizable, allowing enthusiasts to tailor their setup to meet specific performance goals and driving preferences.

Preparing for Turbocharging

Before diving into the turbocharging process, it’s crucial to ensure your Acura Integra B-Series engine is in good condition. This includes performing routine maintenance, such as oil changes, spark plug replacements, and ensuring all components are functioning correctly.

Additionally, upgrading certain components can help prepare your engine for the increased stress of turbocharging. Upgrading the fuel system, including injectors and fuel pump, is essential to ensure adequate fuel delivery to the engine under boost. Upgrading the engine’s internals, such as forged pistons and connecting rods, can also improve durability and reliability under high boost levels.

Choosing the Right Turbocharger

Selecting the right turbocharger for your Acura Integra B-Series engine is crucial to achieving optimal performance. Considerations such as desired power output, engine displacement, and intended use should guide your decision. It’s essential to choose a turbocharger that matches your engine’s characteristics and operating parameters to ensure efficient and reliable performance.

Factors to consider when selecting a turbocharger include compressor size, turbine size, boost threshold, and compressor efficiency. Consulting with experienced professionals or enthusiasts familiar with turbocharging Acura Integra engines can provide valuable insights and recommendations.

Upgrading Engine Management

Turbocharging significantly alters the engine’s operating parameters, requiring appropriate adjustments to fuel delivery, ignition timing, and boost control. Upgrading to a standalone engine management system, such as Hondata or AEM, is often necessary to properly tune the engine for turbocharged operation.

A standalone engine management system allows for precise control over fuel and ignition timing, as well as the ability to monitor and adjust boost levels. Tuning the engine for optimal performance and reliability is essential to prevent detonation, knock, and other potentially damaging conditions associated with turbocharging.

Upgrading Exhaust and Intake Systems

An efficient exhaust system is essential for maximizing the performance of a turbocharged engine. Upgrading to a high-flow exhaust manifold and downpipe reduces exhaust backpressure, allowing the turbocharger to spool more quickly and efficiently.

Similarly, upgrading the intake system with a high-flow air filter and intake manifold improves airflow into the engine, enhancing turbocharger response and overall performance. Cold air intake systems can also help lower intake air temperatures, improving engine efficiency and power output.


Intercooling is a crucial component of any turbocharged setup, as it helps reduce intake air temperatures and increase air density, resulting in more power and improved engine reliability. Intercoolers come in various designs, including air-to-air and air-to-water configurations.

Installing a properly sized and efficiently designed intercooler ensures that the compressed air from the turbocharger remains cool and dense as it enters the engine. This helps prevent detonation and knock, which can occur when intake air temperatures become too high, especially under boost.


Turbocharging your Acura Integra B-Series engine is a rewarding endeavor that can transform your car’s performance and driving experience. By understanding the principles of turbocharging and carefully selecting the right components, you can unleash the full potential of your Integra while maintaining reliability and drivability.

From choosing the right turbocharger to upgrading engine management and optimizing exhaust and intake systems, each step plays a crucial role in achieving the desired performance gains. With proper preparation, installation, and tuning, turbocharging your Acura Integra B-Series engine can take your driving experience to new heights, whether on the street or the track.
