West Coast Fiero, a renowned name in the automotive industry, has been a staple in the Fiero community for performance parts since 1986. They have been instrumental in providing valuable insights and resources for engine conversions. Their guide, “What It Takes”, is a comprehensive manual that details the requirements for installing various engine conversions. This article will delve into some of the common engine conversions, namely the 3800, 3.4, 4.9, and LS4.
The 3800 engine conversion is one of the most popular due to its balance of power and efficiency. This conversion involves replacing the original engine with a 3800 series engine, which is known for its robust performance and reliability. The process requires a detailed understanding of the engine’s specifications and the vehicle’s compatibility.
The 3800 engine is a V6 engine that offers a significant upgrade in power and torque compared to the standard Fiero engine. However, it’s important to note that this conversion requires a fair amount of mechanical knowledge and skill, as it involves significant modifications to the vehicle’s existing setup.
The 3.4 engine conversion is another common choice for Fiero owners. This engine, also known as the 5VZ-FE, is a larger displacement engine that provides a noticeable increase in power and torque.
This conversion involves a series of modifications, including changes to the engine mounts, exhaust system, and computer programming. It’s worth noting that this conversion requires a high level of mechanical expertise and a thorough understanding of the vehicle’s systems.
The 4.9 engine conversion is a unique option that involves installing a larger, more powerful engine into the Fiero. This engine, often sourced from Cadillac vehicles, offers a significant increase in power, making it a popular choice for those looking to enhance their vehicle’s performance.
However, this conversion is not without its challenges. It requires extensive modifications to the vehicle, including changes to the engine mounts, exhaust system, and drivetrain. Additionally, it may require adjustments to the vehicle’s suspension and braking systems to accommodate the increased power.
The LS4 engine conversion is perhaps the most ambitious of the four. The LS4 is a small-block V8 engine that offers a substantial increase in power and torque compared to the Fiero’s original engine.
This conversion involves a series of complex modifications, including changes to the engine mounts, intake manifold, exhaust system, and computer programming. Due to the complexity of this conversion, it is typically recommended for experienced mechanics or those with a thorough understanding of the vehicle’s systems.
Engine conversions can breathe new life into a Pontiac Fiero, offering increased power, improved performance, and enhanced driving experience. However, they require a significant amount of mechanical knowledge and expertise. West Coast Fiero’s “What It Takes” guide provides valuable insights into what is required for each conversion, helping Fiero owners make informed decisions about upgrading their vehicles. Whether you’re considering a 3800, 3.4, 4.9, or LS4 engine conversion, it’s essential to understand what it takes to successfully complete the project.
