Stage 3 LS Swap Package

The Sikky Manufacturing Stage 3 LS swap package (MKP001C-STAGE3-LS1) is a comprehensive kit for integrating an LS1 engine into a Nissan 240sx S14 chassis, featuring a new wiring harness from Wiring Specialties. This kit includes: * **Engine Mounts:** CAD/CAM designed, CNC machined from solid 6061 T-6 aluminum with custom urethane bushings, ensuring proper engine placement and axle alignment. These mounts have a lifetime warranty. * **Transmission Mount:** Also CNC machined from solid 6061 T-6 aluminum with a steel bracket and urethane bushing, designed for T56 or T56 Magnum transmissions. It carries a lifetime warranty. * **Driveshaft:** A steel one-piece driveshaft with high-strength 1310 U-joints, designed for T56 or 4L60E transmissions (aluminum upgrade available). * **Aluminum Race Oil Pan:** Features a high ground clearance design that does not hang below the crossmember, a 6.8-quart sump, and is compatible with factory dust covers. It includes a Sikky Oil Pump Pickup Tube, Dip Stick Tube and Dip Stick, a remote oil filter adapter, magnetic drain plug, and necessary hardware. * **Pro Series Headers:** Constructed from 100% stainless steel with massive 1 7/8” primaries, high-flow collectors with merge bullets, CNC head flanges, and Tig welded seams. These are for Left Hand Drive vehicles only. * **Power Steering Lines:** Designed to fit LS1 power steering reservoirs with swiveling fittings for optimal fitment and extreme high-pressure capability (48,000 PSI). Includes a low-pressure return line. * **LS1 Wiring Harness:** Supports 1999-2002 F-Body LS1 (Camaro, Firebird, Trans Am, Corvette), 2004 Pontiac GTO LS1, and 1999-2004 Truck/SUV LSx/Vortec engines with DRIVE BY CABLE THROTTLE ONLY. The harness is plug-and-play, uses OEM connectors and seals, and features fireproof fiberglass sleeving for high-temp sections and high-temp TXL wire. It is wrapped in nylon loom for protection. Fitment notes indicate that while the kit is designed to fit perfectly around the S14's front subframe and does not hang below the crossmember, minor clearancing of the firewall and transmission tunnel may be required. Removal of the factory front sway bar is also necessary for oil pan fitment, and Sikky offers a custom sway bar for this purpose. The kit is designed for use with an LS1 style T56 transmission, but shifter relocation kits and proper driveshafts are available for T56 Magnum applications. A clutch master cylinder kit is required for proper function with a T56 transmission.
