2012-18 Jeep Wrangler JK/JKU 500HP LX3 6.6L to Factory Automatic Transmission
Bruiser Conversions fully tunable LX3 V8 engine conversion system for the Jeep Wrangler JK / JKU maintains the original equipment manufacturers (OEM) functionality of all vehicle systems that were supplied with your vehicle. Therefore, all systems that were functional prior to the conversion process will be functional after the conversion has been completed. This specifically includes things like the instrument cluster, indicators, gauges, powertrain control systems, cruise control, hill descent mode, tip start, tap shift, and more. Our system uses a GM E-38 computer and has the capability of reading both the GM & Jeep side from a dual OBD port system.
Bruiser Conversions provides the only fully tunable LX3 V8 engine conversion for the JK / JKU Wrangler.
LT engine conversions have replace the LS engine swap
GM has released their best small-block V8 yet with the Gen-V LT engine family! Therefore, the production of GM LS engine blocks has all but halted. The LS3 crate engine from GM Performance is no longer available. No worries! Bruiser Power Solutions has designed, tested, and released the LX3 crate engine, an LT-based engine with port injection using a Gen-IV operating system. It’s a 6.6L torque monster without the tuning and RPM limitations of factory direct injection.
Bruiser Conversions developed this complete, bolt-in, and integrated LX3 V8 crate engine kit for your JK project!
Transmission NOT INCLUDED
(bolts directly to the Jeep factory NAG-1 transmission)
2012 – 2018 JK/JKU Wrangler conversions maintain the NAG-1/722.6/W5A580/WA580 automatic transmission which connects to the LX3 engine using a proprietary adapter assembly. This compact 5-speed automatic transmission is rated at 580 ft-lb torque input capacity.  It has been used in a wide range of vehicles including the Dodge Challenger, Chrysler 300 SRT8, Porsche, Mercedes-Benz Sprinter, Dodge Magnum SRT8, and the supercharged Jaguar X308.  A performance tuned TCM is provided with each engine conversion system.
