  • Limited Offer
  • Regular price $3,449.00



Vehicle: 1989-1994 Nissan 240sx S13 (USDM)

The Sikky Manufacturing Wiring Specialties Turn Key Swap Kit is the first of it’s kind on the market. If you have a S13 chassis, LS1 motor and T56 transmission then this is the kit for you!

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: This kit does require some clearancing of the fire wall and trans tunnel to allow for fitment. This is fairly minor however and can be seen in our instruction manual listed on the instructions tab.

Transmission and Shifter – This kit is designed to work with an LS1 style T56 transmission. This will allow the shifter to locate in the factory location. If you are interested in running a T56 magnum we also offer shifter relocation kits to help locate the shifter in the proper location. We can also accommodate you with the proper driveshaft as well for that application. The master cylinder kit we offer is required for proper function when using a T56 transmission.

Removal of the factory front sway bar (or factory replacement) is required for oil pan fitment. We offer a custom sway bar for proper fitment and clearance

 WIRING SPECIALTIES HARNESS: 

Looking for the best in aesthetics, weight savings and reliability out of your harness?  Our Pro Series harness completely replaces your old OEM harness so you can forget about those electrical gremlins.

This Wiring Specialties PRO Series harness was designed from the ground-up to exceed OEM specifications for wire quality, power/ground routing. With our optimized and ‘tucked’ approach the end result will be a clean and worry free installation with a guaranteed start up.

This harness is specifically engineered for a USDM LHD S13 Nissan 240sx (89-94) with the GM LS1 Cable Throttle engine swap. It was developed in house on an actual LS1 engine in an S13 240sx chassis to ensure a perfect fit to all engine connections.

Wiring Specialties offers a number of options for common performance upgrades for this product. Build your perfect harness by selecting from the available options to the right, and as always – if you have any questions, please reach out to us.

Note: LS2 and up engines, additional accessories and other injector types are subject to additional fees.
