Understanding the AMC AMX
The AMC AMX, produced from 1968 to 1970, is known for its unique styling and powerful performance. With a lightweight body and a variety of engine options, it provides a solid platform for performance upgrades. Understanding the AMX’s specifications will help in selecting the right modifications.
- Engine options ranged from a 290 cubic inch V8 to a 401 cubic inch V8.
- It features a rear-wheel-drive layout, enhancing its performance capabilities.
- The AMX was designed for both speed and handling, making it a great candidate for upgrades.
Performance Upgrade Options
To achieve a 75 HP increase, several modifications can be made. Below are some of the most effective upgrades that can be completed within a budget of $2,000.
1. Cold Air Intake System
Upgrading to a cold air intake system can significantly improve airflow to the engine, resulting in better combustion and increased horsepower. A quality cold air intake can be purchased for around $300 to $500.
2. High-Performance Exhaust System
A high-performance exhaust system reduces back pressure and allows exhaust gases to exit more freely. This upgrade not only enhances performance but also provides a more aggressive sound. Expect to spend between $500 and $800 for a good system.
3. Performance Camshaft
Installing a performance camshaft can optimize engine timing and improve horsepower. A new camshaft can cost between $400 and $600, and it can yield a substantial increase in power when paired with other modifications.
4. Re-gearing the Differential
Changing the differential gears can improve acceleration. For an AMC AMX, re-gearing can cost around $300 to $500. This upgrade helps the engine reach its power band more quickly, enhancing overall performance.
5. Tuning the Engine
After making hardware upgrades, tuning the engine is essential to maximize performance. A professional tune can cost between $200 and $400, ensuring that all components work together efficiently for optimal power output.
Estimated Costs and Performance Gains
Here’s a breakdown of the estimated costs for each upgrade and the potential horsepower gains:
- Cold Air Intake System: $300 – $500 (10-15 HP)
- High-Performance Exhaust System: $500 – $800 (15-20 HP)
- Performance Camshaft: $400 – $600 (20-25 HP)
- Re-gearing the Differential: $300 – $500 (5-10 HP)
- Engine Tuning: $200 – $400 (5-10 HP)
When combined, these upgrades can easily yield a total horsepower increase of 75 HP or more, all while staying within the $2,000 budget.
