The Dodge Neon SRT-4 is a beloved compact car among enthusiasts, known for its turbocharged engine and sporty performance. Achieving 250 wheel horsepower (WHP) is a common goal for many SRT-4 owners. This article will guide you through the necessary modifications, estimated costs, and expected results to reach that power level.
Understanding the Basics
Before diving into modifications, it’s essential to understand the basics of the Dodge Neon SRT-4’s engine and performance metrics. The SRT-4 is equipped with a 2.4L inline-four engine, featuring a turbocharger that significantly boosts power output. The stock configuration typically produces around 205 WHP, making it a solid platform for tuning.
Key Modifications to Achieve 250 WHP
1. ECU Tune
The first step in increasing your SRT-4’s power is to reprogram the engine’s ECU. A proper tune can unlock additional horsepower and torque by optimizing fuel delivery and ignition timing.
2. Upgraded Turbocharger
Replacing the stock turbocharger with a larger unit will significantly increase airflow and boost pressure. Options like the GT28 or a Big Turbo Kit can help you reach your power goals.
3. High-Performance Intercooler
A high-performance intercooler is crucial for reducing intake temperatures and preventing heat soak, which can lead to detonation. Look for options that offer improved efficiency and fitment.
4. Exhaust System Upgrade
Upgrading the exhaust system, including a high-flow downpipe and cat-back exhaust, will enhance exhaust flow and reduce back pressure. This modification not only increases power but also improves the sound of your SRT-4.
5. Intake System
A high-flow intake system will allow your engine to breathe better. Consider a cold air intake or a short ram intake to maximize airflow.
6. Fuel System Upgrades
To support increased power levels, upgrading the fuel system is necessary. This includes larger fuel injectors and a high-performance fuel pump to ensure adequate fuel delivery.
7. Engine Internals (Optional)
If you plan to push beyond 250 WHP, consider upgrading engine internals such as pistons and rods. This modification is optional for reaching 250 WHP but may be necessary for higher power levels.
Estimated Costs of Modifications
The costs of reaching 250 WHP can vary significantly based on the parts chosen and whether you perform the installation yourself or hire a professional. Below is a rough estimate of the costs associated with each modification:
- ECU Tune: $300 – $600
- Upgraded Turbocharger: $600 – $1,500
- High-Performance Intercooler: $300 – $800
- Exhaust System Upgrade: $400 – $1,000
- Intake System: $200 – $500
- Fuel System Upgrades: $400 – $800
- Engine Internals (Optional): $1,000+
In total, expect to spend anywhere from $2,800 to $5,500 or more, depending on your choices.
Expected Results
After completing the modifications and tuning your SRT-4, you can expect to achieve around 250 WHP. However, results may vary based on factors such as the quality of parts used, the tuning process, and the condition of your vehicle.
Conclusion
Achieving 250 WHP on a Dodge Neon SRT-4 is an attainable goal with the right modifications and tuning. By investing in quality parts and ensuring proper installation, you can enjoy a significant boost in performance. Always remember to consult with professionals if you’re unsure about any modifications, and happy tuning!
