Stage 3 LS3 Swap Clutch Kit

This Stage 3 kit from Sikky provides essential components for mounting a GM LS3 engine into a BMW E30 chassis. The package includes Sikky's industry-leading motor mounts, transmission mount, oil pan, driveshaft, power steering lines, headers, and a wiring harness, with various optional add-ons to facilitate a turnkey installation. The kit is compatible with LS1, LS2, LS3, LS6, L99, LQ4, LQ9, LSA, LS7, LS9, LSX, and other LS-based engines utilizing the specified bolt pattern. It requires no modifications to the factory crossmember or subframe and is designed not to hang below the crossmember. Installation necessitates the use of an E36 steering rack and eye ball arms for header clearance, along with Sikky's low-profile steering shaft. A brake booster delete kit is required for manual brake E30s to ensure clearance for the driver's side head. The kit is designed to work with an LS1 style T56 transmission, allowing the shifter to pass through the factory opening. The factory master cylinder will need to be removed or replaced for engine clearance. Key components include a 6.8-quart capacity aluminum race oil pan with a 1/2” thick billet flange, designed for high ground clearance and featuring a remote oil filter adapter. The engine and transmission mounts are CNC machined from solid 6061 T-6 aluminum with urethane bushings and come with a lifetime warranty. The stainless steel headers feature 1 7/8” primaries and v-band collectors. The included wiring harness from Wiring Specialties is designed for plug-and-play installation, featuring integrated coil pack harnesses, a standalone 5-circuit fuse/relay block, and high-temperature protection on critical sensor branches. The harness utilizes OEM wire colors where applicable and EM shielded wires for sensor signals. This wiring harness is specifically designed for GM 6.2 LITER LS3 ENGINES USING DRIVE BY WIRE / ELECTRONIC THROTTLE, including specific applications such as the 2011-2014 Chevrolet Camaro, 2008-2014 Chevrolet Corvette, and 2006 Chevrolet Tahoe/Silverado. It also supports various Cadillac Escalade, Chevrolet Silverado/GMC Truck/Van, and Chevrolet/GMC Truck/SUV models with 6.2L or 6.0L engines. The harness uses high-temp TXL wire and is wrapped in nylon loom, with specialized protection on knock and O2 sensor branches capable of withstanding temperatures up to 450°C/845°F.
