Top Supporting Mods for Ls Swap Z Cars: Best Intakes, Exhausts, and Drivetrain Upgrades

by

LS swapping Z cars has become a popular trend among automotive enthusiasts looking to enhance performance and reliability. The combination of the lightweight Z chassis and the powerful LS engine creates an exhilarating driving experience. However, to maximize the potential of this swap, it’s essential to consider supporting modifications that improve airflow, exhaust flow, and drivetrain efficiency. In this article, we will explore the top supporting mods for LS swapped Z cars, focusing on the best intakes, exhausts, and drivetrain upgrades.

Best Intakes for LS Swap Z Cars

A high-performance intake system is crucial for optimizing the airflow into the LS engine, which can significantly improve horsepower and torque. Here are some of the best intake options for LS swap Z cars:

  • Cold Air Intake Systems: These systems draw cooler air from outside the engine bay, enhancing combustion efficiency. Popular brands include Airaid and K&N.
  • LS3 Intake Manifold: Upgrading to an LS3 manifold can provide better airflow and performance compared to stock intakes.
  • Aftermarket Throttle Bodies: Larger throttle bodies from companies like Fast or Holley can improve throttle response and overall engine performance.

Top Exhaust Systems for LS Swap Z Cars

Exhaust systems play a vital role in improving engine performance by allowing exhaust gases to exit the engine more efficiently. Here are some recommended exhaust upgrades:

  • Long Tube Headers: These headers improve exhaust flow and can significantly increase horsepower. Brands like Hooker and American Racing offer quality options.
  • Cat-Back Exhaust Systems: A cat-back system from manufacturers like Borla or MagnaFlow can enhance sound and performance while maintaining emissions compliance.
  • High-Flow Catalytic Converters: Upgrading to high-flow cats can improve exhaust flow without sacrificing too much on emissions.

Essential Drivetrain Upgrades for LS Swap Z Cars

To handle the increased power and torque from an LS engine, it’s essential to upgrade the drivetrain components. Here are key upgrades to consider:

  • Transmission Swap: Consider swapping to a T56 or a 4L60E for better gear ratios and reliability.
  • Upgraded Differential: A stronger differential, such as an R200 with a limited-slip, can handle the added power and improve traction.
  • Driveshaft Upgrades: A lightweight, high-strength driveshaft can reduce rotational mass and improve drivetrain efficiency.

Additional Performance Enhancements

Beyond intakes, exhausts, and drivetrain components, several other modifications can help maximize the performance of your LS swapped Z car:

  • ECU Tuning: A custom tune can optimize engine performance by adjusting fuel maps and ignition timing.
  • Upgraded Fuel System: Ensure your fuel system can support the LS engine with larger injectors and a high-flow fuel pump.
  • Suspension Upgrades: Enhancing the suspension with coilovers or sway bars can improve handling and stability.

Conclusion

Modifying a Z car with an LS engine swap opens up a world of performance possibilities. By focusing on supporting mods such as intakes, exhausts, and drivetrain upgrades, enthusiasts can create a powerful and reliable vehicle. Each modification plays a crucial role in enhancing the overall performance, ensuring that your LS swapped Z car not only performs well but also delivers an exhilarating driving experience.
