The H22 engine is a popular choice among car enthusiasts looking to boost performance without breaking the bank. With a budget of under $2000, it is possible to create a reliable turbo build that enhances power and efficiency. This article outlines the essential components needed for a budget-friendly H22 turbo build.
Understanding the H22 Engine
The H22 engine, originally designed by Honda, is known for its high-revving capabilities and solid performance. It features a DOHC design and is commonly found in models such as the Honda Prelude and Accord. The engine’s robust structure makes it an ideal candidate for turbocharging.
Essential Parts for a Budget-Friendly Turbo Build
- Turbocharger
- Intercooler
- Fuel Injectors
- ECU Tuning
- Exhaust Manifold
- Wastegate
- Blow-off Valve
- Oil Feed and Drain Lines
- Turbo Timer
1. Turbocharger
Choosing the right turbocharger is crucial for achieving the desired performance. A popular choice for H22 builds is the Garrett GT28 or the eBay Turbo Kits, which are both affordable and provide a good balance of power and reliability.
2. Intercooler
An intercooler helps to reduce the temperature of the air entering the engine, which improves performance. Look for a front-mount intercooler that fits within your budget, such as those from eBay or Amazon, which often come at a reasonable price.
3. Fuel Injectors
Upgrading fuel injectors is necessary to ensure that the engine receives adequate fuel supply. Consider 440cc or 550cc injectors, which can be found from reputable brands like RC Engineering or DeatschWerks.
4. ECU Tuning
Proper tuning of the engine’s ECU is essential for maximizing performance and reliability. Options include Hondata or Ktuner, which can be used to adjust fuel maps and ignition timing to accommodate the turbo setup.
5. Exhaust Manifold
A quality exhaust manifold is necessary to efficiently route exhaust gases to the turbocharger. Look for a log-style manifold or a top mount manifold that fits your budget. Brands like Godspeed or eBay offer affordable options.
6. Wastegate
The wastegate controls the boost pressure produced by the turbocharger. A 38mm external wastegate is a reliable choice, with options available from brands like TurboSmart or eBay.
7. Blow-off Valve
A blow-off valve (BOV) prevents compressor surge and helps maintain boost pressure. Look for a plumb back or vent-to-atmosphere BOV from brands like HKS or Greddy.
8. Oil Feed and Drain Lines
Proper oil feed and drain lines are vital for turbo longevity. Consider purchasing a complete oil line kit that includes all necessary fittings, available from various aftermarket suppliers.
9. Turbo Timer
A turbo timer allows the engine to run for a few minutes after shutting off, ensuring that the turbo cools down properly. This is an affordable addition that can prolong the life of your turbocharger.
Conclusion
Building a budget-friendly H22 turbo setup for under $2000 is achievable with careful planning and the right parts. By selecting reliable components and ensuring proper tuning, you can enjoy enhanced performance without compromising on quality.
