Common Swaps (Relatively Easy)
* Chrysler 2.4L (Naturally Aspirated or Turbocharged): This is the most common swap. The 2.4L is a solid engine with good power, and it's a direct bolt-in for the Neon's engine bay.
* 2.4L Naturally Aspirated: This engine is a good upgrade in terms of power, but it won't be as fast as a turbocharged option.
* 2.4L Turbocharged (from Dodge Neon SRT-4 or later models): This is the most popular swap for performance enthusiasts. You'll get a significant power boost, but you'll need to source the turbocharger, intercooler, and supporting components.
* Chrysler 2.0L (Naturally Aspirated): A slightly smaller engine, often found in older Neons and other Chrysler vehicles. While not as powerful as the 2.4L, it's still an improvement over the stock engine.
More Involved Swaps
* Mitsubishi 4G63T: A legendary engine known for its high-performance potential. This swap is more challenging due to wiring and mounting modifications required.
* Honda K-series (K20, K24): Another popular choice for power. These engines require extensive custom work to fit and need to be paired with an appropriate transmission.
Important Considerations
* Transmission: You'll need to ensure your transmission is compatible with the new engine. If not, you'll need to swap the transmission as well.
* Wiring: Different engines will have different wiring harnesses, so you may need to modify the existing harness or source a new one.
* ECU (Engine Control Unit): You'll need to ensure the new engine's ECU is compatible with your car's electrical system.
* Exhaust: The new engine might require a different exhaust system.
Before You Swap
* Research: Thoroughly research the engine you're considering and the required modifications. Many online forums and communities dedicated to Neon swaps can be helpful.
* Budget: Engine swaps can be expensive, so factor in the cost of the engine, parts, labor (if you're not doing it yourself), and any necessary modifications.
* Technical Skills: Engine swaps require a significant amount of mechanical knowledge and skills. If you're not comfortable with the work involved, consider hiring a professional mechanic.
