What are some common modifications to increase horsepower in a 1999 GMC Sonoma or a 2003 Corvette Z06 LS6?

The LS6 engine from the 2003 Corvette Z06 can produce up to 405 horsepower, a significant increase from the stock 1999 GMC Sonoma's 190 horsepower.

The LS6 engine is lighter than the stock engine in the Sonoma, which can improve overall vehicle performance.

To accommodate the LS6 engine in a 1999 Sonoma, modifications to the engine bay and drivetrain are necessary, such as using a 2003 Z06 wiring harness and PCM.

The stock LS6 engine uses a dry-sump oiling system, which may need to be converted to a wet-sump system for use in the Sonoma.

A custom fuel system, including a fuel tank and fuel lines, is required due to the different fuel flow requirements of the LS6 engine.

The LS6 engine is larger than the stock engine, which may require modifications to the hood or engine bay for proper clearance.

To handle the increased power of the LS6 engine, upgrades to the transmission, drivetrain, and brakes are often necessary.

A custom exhaust system is required to accommodate the LS6 engine, which can also help increase horsepower.

Tuning the LS6 engine and fuel system for use in the Sonoma can improve performance and drivability.

The weight distribution of the Sonoma can be significantly altered with the addition of the LS6 engine, requiring adjustments to the suspension and handling for optimal performance.

The stock gauges and instruments in the Sonoma may need to be upgraded to handle the increased power and performance of the LS6 engine.
