The LS engine has become a popular choice for enthusiasts looking to upgrade their Z cars, offering a blend of power and reliability. With the right components, you can boost your engine from 400 to 800 horsepower. In this article, we will explore the best GMPP (General Motors Performance Parts) and Callies components to achieve this transformation.
Understanding the LS Engine
The LS engine family, introduced by General Motors, is known for its lightweight design and high-performance capabilities. It features an aluminum block, which contributes to its efficiency and power potential. The versatility of the LS engine allows it to be adapted for various applications, including the Z car platform.
Setting Your Goals
Before diving into the upgrade process, it’s crucial to set clear performance goals. Upgrading from 400 to 800 horsepower requires careful planning and the right components. Consider the following:
- Desired horsepower level
- Type of driving (street, track, or both)
- Budget for parts and labor
Key Components for Upgrading
To achieve the desired horsepower, selecting the right components is essential. Here are some of the top GMPP and Callies components to consider:
GMPP Components
