Stage 3 LS3 Swap Flywheel Kit

The Sikky Stage 3 LS3 Swap Package is a master swap kit engineered to facilitate the installation of an LS3 engine into the Toyota 86 / FRS chassis with minimal remaining work. This comprehensive kit includes a brand-new wiring harness meticulously built by Wiring Specialties, tailored to your specific configuration choices, which can include options for intake manifold type, oxygen sensor type, oil pressure sensor, alternator selection, engine start setup, fuel pump setup, pedal options, and AC integration. Included in the package is a high-capacity aluminum race oil pan with a 7.4-quart sump, designed for optimal ground clearance and fitment around the FRS/86/BRZ front subframe when used with Sikky mounts. The kit also features a remote oil filter setup with -10 AN fittings and stainless braided lines. The engine mounts are constructed from CNC laser-cut steel and 6061 billet aluminum with custom urethane bushings, ensuring proper engine placement and pinion angle alignment, and come with a lifetime warranty. The transmission mount, designed for 6-speed T56, T56 Magnum, and TR6060 transmissions, also includes a lifetime warranty. Performance is enhanced with 100% stainless steel headers featuring 1 7/8” primaries and high-flow 3″ collectors with V-band flanges. The package is completed with a driveshaft. It's important to note that the wiring harness has a standard lead time of 4-8 weeks, as it is built to order. Additionally, the user must select the appropriate PCM configuration, and if not an expert GM tuner, it is recommended to contact Wiring Specialties to purchase a PCM. The driveshaft may not work with subframe and/or diff risers, and exhaust tucking can be challenging.
