The ISR Performance LS Swap Mounts are engineered as a complete solution for installing RWD LSx-based motors in the 2003-2008 Nissan 350Z Z33. These mounts provide the versatility to accommodate both the factory 350Z 6-speed transmission (when paired with the CD Adapter kit) and the F-Body LS T56 transmission (when paired with the T56 350Z shifter).

Key Features

  • Engine and Transmission Compatibility: Designed to work seamlessly with RWD LSx motors, these mounts are compatible with a variety of setups, ensuring a smooth installation process.
  • Urethane Bushings: Featuring high-quality urethane engine and transmission mount bushings, ISR Performance mounts effectively dampen engine vibrations without compromising performance. This makes them suitable for daily driving as well as track applications.
  • Flexible Installation: The unique design incorporates a small base mount pedestal and a separate mount bracket, allowing for precise fitment and easy installation on your subframe.
  • Complementary Products: Enhance your setup with optional ISR components, including the (IS-ZLS-SHFT) T56 350Z shifter relocation kit and (IS-SSHD-350LS) ISR HGC LS headers, which bolt directly to the stock 350Z Y-pipe location, allowing you to retain existing factory components or pair with the ISR 350Z Y-pipe and cat-back exhaust.

Important Installation Notes
To ensure proper fitment of the LS engine in your 350Z, it is crucial to use the ISR Performance 350Z swap oil pan. Please note that OEM GTO pans and off-the-shelf Canton pans are not compatible. Any attempt to install an LS-based engine without the designated ISR oil pan may result in fitment issues and damage; responsibility for such issues will fall on the installer.
