Sikky Manufacturing

Sikky Mfg - Nissan 350Z LSx Swap Kit- Stage 2 (headers included)


The Sikky LSX swap kits are designed for use with the LS series of motors (LS1-LS9) and the T-56 transmission.

Our kit requires no modifications to the factory cross member or subframe and does not hang below the crossmember when installed. 

When using the Sikky kit it’s a direct drop in solution.

The Sikky motor mounts are CNC machined billet aluminum versus the mig welded sheet metal mounts that other kit manufacturers provide.

Our products are built to the highest standards.

Every component offered in the kit was completely designed in house by our team of engineers from the ground up.

Unlike our competitors that retro fit off the shelf bushings and other parts from different manufacturers, our urethane transmission and motor mount bushings are designed specifically for these applications. 

We build our oil pans with a 1/2″ thick flange and back plate to provide superior strength that will outlast and outperform other pans available. 

All our products are tested under rigorous track conditions to ensure our customers are provided only the highest quality parts available.

Fitment Notes: Our 350z kit does not require removal of the secondary firewall like our competitors kits do.  No cutting, drilling spot welds or modifications required, making this an easy bolt in job.

Currently this kit is develop for left hand drive vehicles. Removal of the front sway bar is required for oil pan clearance.

Transmission and Shifter – This kit is designed to work with the LS1 style T56. Supplied with our kit is a relocated shifter to allow for the shifter handle to locate through the factory hole. If you are choosing to go with an automatic transmission or a T56 magnum, give us a call and we can modify the package accordingly.

Wiring – Wiring harnesses are now available from Wiring Specialties to allow for the factory gauge cluster to function. This will allow for a plug and play installation of the harness as well.
