ISR Performance oil pan kit for LS Swap Mounts for Nissan 350Z Z33 03-08

The ISR Performance LS Swap Oil Pan Kit is the custom oil pan, pickup tube, and dipstick combination required for LS engine swaps into the 2003-2008 Nissan 350Z (Z33) using ISR Performance swap mounts. The pan is designed lower and further back than other aftermarket LS swap pans on the market, which is what allows the engine to sit in the ISR-specified mount position. Includes integrated baffling to help prevent oil starvation during track use.

What It Does

LS engines weren't designed to fit between the 350Z's frame rails, and the factory LS oil pan won't clear the Z33 subframe and steering rack. A swap-specific pan is mandatory. This pan is purpose-built for the ISR mount kit, sitting the engine lower and further back in the chassis than other LS swap pans, which improves weight distribution and clearance for the rest of the engine bay. The integrated baffling helps keep oil at the pickup during hard cornering and track use, which is critical on a high-performance build.

Critical Fitment Requirements

Designed for the ISR Performance LS Swap mount kit specifically. The pan sits lower and further back than competing pans, which means it depends on the specific engine position set by ISR's mounts. If you're using a different brand of swap mounts or custom-fabricating your own, this pan may not clear the subframe correctly. Custom mount builders should plan around this pan's dimensions before fabricating.

Windage tray trimming may be required. Depending on which OEM windage tray you're running on your LS engine, you may need to trim the tray to properly mount the custom oil pickup tube. Plan accordingly during the build.
