After spending quite some time building and testing the all new LSx swap kit for 350z chassis we are proud to offer it for sale!

Our kit is designed to be an easy, straight forward installation allowing you to utilize either the standard GM T56 transmission, or a factory 350z transmission (with optional CD00x adapter kit). 

The "HGC" High Ground Clearance 350z LSx swap headers also utilize an innovative design feature, placing the collector at an angle and locating it above the factory chassis bracing. To allow even easier installation and to avoid costly and time consuming fabrication, the ISR Performance HGC headers terminate at a 2 bolt flange which is designed to mate up to your existing aftermarket Y Pipe and exhaust (Pair it with the ISR Y pipe and single GT or EP Dual for free flow and great sound)!
