The AMC AMX is a classic American muscle car that has captured the hearts of enthusiasts for decades. With its sleek design and powerful engine, it’s no wonder that many car lovers are looking to enhance its performance. If you’re aiming to achieve 400+ horsepower without breaking the bank, this guide will outline some of the top performance modifications you can make to your AMC AMX, all for under $1,500.
Understanding the AMC AMX Engine
The AMC AMX was originally equipped with a variety of engines, from the 290 V8 to the powerful 401 V8. The 390 and 401 engines are particularly popular among performance enthusiasts. Understanding your engine type is crucial as it will guide your modification choices.
Top Performance Mods for AMC AMX
1. Cold Air Intake
A cold air intake system can significantly improve your engine’s airflow, leading to better combustion and increased horsepower. By replacing the factory air intake with a high-performance cold air system, you can expect to gain around 10-15 horsepower for a relatively low cost.
2. High-Performance Exhaust System
Upgrading to a high-performance exhaust system allows for better exhaust flow, reducing back pressure and improving engine efficiency. Look for a cat-back exhaust system designed for your AMC AMX, which can provide a horsepower increase of 15-20 HP.
3. Carburetor Upgrade
Replacing your factory carburetor with a larger, performance-oriented carburetor can enhance fuel delivery and improve throttle response. Depending on the size and type, you could see an increase of 20-30 horsepower.
4. Performance Camshaft
A performance camshaft can optimize your engine’s timing and improve airflow. Choosing a camshaft designed for high horsepower can net you an additional 30-50 horsepower, depending on the specifications.
5. Ignition System Upgrade
Upgrading your ignition system, including the distributor, coil, and spark plugs, can lead to a more efficient combustion process. A high-quality ignition system can provide a horsepower increase of around 10-15 HP while also improving engine reliability.
6. Gear Ratio Change
Changing the rear-end gear ratio can significantly improve acceleration and overall performance. A lower gear ratio allows for quicker acceleration, making your AMC AMX feel more powerful on the road. This modification is often overlooked but can be very effective.
7. Lightweight Flywheel
Installing a lightweight flywheel can reduce rotational mass, allowing your engine to rev more freely and respond quicker to throttle inputs. This modification can enhance your AMX’s overall performance and contribute to a more exhilarating driving experience.
