For enthusiasts looking to enhance their Grand National’s performance without breaking the bank, there are several budget-friendly parts that can help achieve 350 horsepower for under $1,500. In this article, we will explore the best performance parts available for the Buick Grand National.
Understanding the Buick Grand National
The Buick Grand National was produced from 1982 to 1987 and is celebrated for its blend of luxury and performance. The stock engine produces around 200 horsepower, but with the right modifications, it can easily reach higher power levels. The goal of this article is to outline cost-effective upgrades that maximize performance while keeping expenses below $1,500.
Key Performance Parts to Consider
- Cold Air Intake System
- High-Performance Exhaust System
- ECM Chip Upgrade
- Intercooler Upgrade
- Fuel Pump Upgrade
- Boost Controller
- Aftermarket Turbocharger
1. Cold Air Intake System
Upgrading to a cold air intake system is one of the simplest and most effective modifications you can make. A cold air intake allows your engine to breathe better by drawing in cooler air, which can lead to increased horsepower. Many aftermarket options are available for the Grand National, typically costing between $200 to $300.
2. High-Performance Exhaust System
A high-performance exhaust system not only improves the sound of your Grand National but also enhances exhaust flow, which can lead to better performance. Look for a cat-back exhaust system designed specifically for the Grand National, which usually costs around $400 to $600.
3. ECM Chip Upgrade
Upgrading the engine control module (ECM) chip can significantly improve engine performance by optimizing fuel maps and ignition timing. This modification typically costs about $200 and can yield noticeable gains in horsepower and torque.
4. Intercooler Upgrade
An upgraded intercooler can help reduce intake air temperatures, allowing for more efficient combustion and increased power. While prices can vary, a decent aftermarket intercooler can be found for around $400, making it a worthwhile investment for serious performance enthusiasts.
5. Fuel Pump Upgrade
To support higher horsepower levels, upgrading the fuel pump is essential. A higher-capacity fuel pump ensures that your engine receives the necessary fuel under boost conditions. Expect to spend around $150 to $250 for a quality fuel pump upgrade.
6. Boost Controller
A boost controller allows you to adjust the turbocharger’s boost levels, which can lead to significant increases in horsepower. There are many options available, and you can find a reliable boost controller for approximately $100 to $200.
7. Aftermarket Turbocharger
If you’re looking for a more aggressive power increase, consider upgrading to an aftermarket turbocharger. While this option can be pricier, some budget-friendly turbo options are available for around $600 to $800. This upgrade can help you reach or exceed the 350 horsepower goal.
Putting It All Together
By combining these performance parts, you can achieve a significant boost in horsepower without exceeding your budget. Here’s a possible combination of parts to reach 350 horsepower:
- Cold Air Intake: $250
- High-Performance Exhaust: $500
- ECM Chip: $200
- Intercooler: $400
- Fuel Pump: $200
- Boost Controller: $150
- Aftermarket Turbo: $600
Total Estimated Cost: $2,350 (with turbo upgrade) or $1,750 (without turbo upgrade).
Conclusion
Upgrading your Buick Grand National to achieve 350 horsepower is an exciting journey that can be accomplished on a budget. By carefully selecting performance parts and considering your specific goals, you can enhance the capabilities of your classic muscle car without overspending. Whether you choose to go for a full turbo upgrade or stick with simpler modifications, each upgrade will contribute to the overall performance and enjoyment of your Grand National.
