ISR Performance LS Swap Mounts for Nissan 350Z - Mounts Only, No Shifter

The ISR Performance LS Swap Mounts are the engine and transmission mounting solution for installing a GM LS-based engine into the 2003-2008 Nissan 350Z (Z33) with an F-body T56 or CD009 transmission. This is the Mounts Only configuration, no shifter or accessory pieces included. Engineered as a one-stop solution for clean RWD LS swaps into the Z33 chassis.

What It Does

This kit replaces the factory VQ35 mounting hardware with LS-specific engine and transmission mounts plus a chassis crossmember sized for the F-body T56 and CD009 transmissions. The base mount pedestals and separate mount brackets are designed to pivot, which lets you fine-tune engine position to clear driveline and accessory packaging on your specific build. Urethane bushings on both the engine and transmission mounts dampen vibration without being overly stiff, making this kit appropriate for both daily-driven and track-driven cars.

Critical Requirement: ISR Performance LS Swap Oil Pan

You MUST use the ISR Performance 350Z LS swap oil pan in conjunction with these mounts. The mount geometry was developed around the ISR oil pan, and other pans will not clear the Z33 subframe correctly.

• OEM GTO oil pans WILL NOT WORK
• Off-the-shelf Canton pans WILL NOT WORK
• Attempting to fit an LS engine into a 350Z without the ISR oil pan is at the installer's own risk for damage and fitment issues

What's NOT Included

This is the Mounts Only SKU. The kit does NOT include:

• Shifter (the standard ISR LS swap mount kit includes a shortened CD shifter; this variant does not)
• Oil pan (purchased separately)
• Headers (purchased separately)
• Y-pipe or exhaust components (purchased separately)

Transmission Compatibility

The included crossmember and GM-style transmission mount fit both the F-body T56 and the CD009 six-speed transmissions.
