Omni Gen V LT4 Performance Packages

The Omni Gen V LT4 Performance Packages have been developed from years of real-world testing on our own vehicles and hundreds of customer builds. Rather than offering random combinations of parts, we’ve created complete performance packages that complement one another, maximizing horsepower, reliability, and drivability at every level.

Whether you own a Corvette Z06, Camaro ZL1, or Cadillac CTS-V, each package has been carefully designed to provide a proven upgrade path. Every stage builds upon the previous one, allowing you to increase performance as your goals grow without replacing unnecessary parts along the way.

From the first bolt-on modifications to max-effort factory LT4 combinations, every package is assembled using premium components from industry-leading manufacturers and is backed by professional installation and in-house dyno tuning.

Every package includes the attention to detail that has made Omni Motorsports a trusted name in the GM performance community. We don’t chase inflated dyno numbers—we build combinations that perform consistently, remain reliable, and can be enjoyed both on the street and at the track.
