The journey from a stock engine to a high-performance powerhouse is a thrilling venture for any car enthusiast. In this article, we will explore the transformation of the H22 engine into a formidable 420 horsepower beast using Precision 62mm turbos and custom tuning.
Understanding the H22 Engine
The H22 engine, produced by Honda, is a 2.2-liter inline-four that has garnered a loyal following among tuners. Its robust design and potential for high horsepower make it an ideal candidate for turbocharging.
Choosing the Right Turbochargers
For this build, we opted for Precision 62mm turbos, known for their efficiency and ability to produce substantial power. Here’s why they are an excellent choice:
- Size and Efficiency: The 62mm turbos strike a balance between spool time and power output.
- Durability: Precision turbos are built to withstand high temperatures and pressures.
- Performance: They provide a significant increase in horsepower without sacrificing reliability.
Preparing the Engine for Turbocharging
Before installing the turbos, several modifications were necessary to ensure the H22 engine could handle the increased power. These preparations included:
- Upgraded Pistons: Forged pistons were installed to withstand higher pressures.
- Strengthened Rods: Connecting rods were replaced with stronger alternatives to prevent failure.
- Enhanced Cooling: An upgraded intercooler was added to manage the increased heat generated by the turbos.
Installation of Precision 62mm Turbos
Installing the turbos requires precision and attention to detail. The process involves:
- Turbo Manifold: A custom turbo manifold was fabricated to fit the H22 engine.
- Exhaust Routing: Proper exhaust routing was essential to maximize turbo efficiency.
- Oil Supply Lines: Dedicated oil supply lines were installed to ensure proper lubrication.
Custom Tuning for Maximum Performance
Once the turbos were installed, custom tuning was critical to unleash the engine’s full potential. This phase included:
- ECU Remapping: The engine control unit (ECU) was remapped to accommodate the new turbo setup.
- Fuel Management: Upgraded fuel injectors and a high-flow fuel pump were installed to ensure adequate fuel delivery.
- Dyno Tuning: The car was taken to a dyno for real-time tuning to achieve optimal performance.
Results of the Build
After completing the turbo build and tuning process, the H22 engine was tested on the dyno, achieving an impressive 420 horsepower. This significant power increase was a testament to the effectiveness of the Precision 62mm turbos and the meticulous tuning process.
Conclusion
Transforming a stock H22 engine into a 420 hp turbocharged monster is no small feat. With the right components, such as Precision 62mm turbos and thorough custom tuning, it is possible to create an exhilarating driving experience. This build showcases the potential of the H22 engine and the rewards of dedicated automotive craftsmanship.
