Conversions

Engine conversion systems from Bruiser Conversions provide an OEM quality installation and retain the functionality of vehicle systems that were active prior to the conversion process. Our fully integrated LS3 engine conversion for the JK Wrangler uses the factory PCM, with proprietary performance tuning, and the vehicle retains a single OBD II port for diagnostics. We also offer turn-key Cummins R2.8 Turbo Diesel engine conversions for the JK and TJ Wrangler platform and have several performance tuning options available.
