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

The ISR Performance LS swap mounts are designed to be your one stop solution for all RWD LSx based motors to fit in your 03-08 Nissan 350Z Z33 

ISR Performance mounts feature a urethane engine and transmission mount bushing to help dampen engine vibration without being overly stiff, the perfect solution for daily driven or track vehicles! 

By utilizing a small base mount pedestal and separate mount bracket the ISR Performance mounts can pivot for perfect fitment and easy installation to your subframe.  Also available for separate purchase is (IS-ZLS-SHFT) T56 350Z shifter relocation kit and (IS-SSHD-350LS) ISR HGC LS headers that bolt to the stock 350Z Y pipe location so you can utilize your existing factory components or match with the ISR 350z Y pipe and cat back exhaust.

You MUST use the ISR Performance 350z swap oil pan in conjunction with these mounts in order to properly fit your engine into the chassis. OEM GTO pans WILL NOT WORK, off the shelf Canton pans WILL NOT WORK. If you attempt to fit an LS based engine into your 350z without using our oil pan you assume all responsibility for damage and possible fitment issues.
