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.

Well as requested these are the numbers for our 716 flywheel w/ 91 octane at 551hp to rear wheel. Our 93 octane tune will put down 573 hp with small adjustments to timing. If you let us know your fuel availability prior to kit shipping we can adjust tune accordingly #jeep #jeepporn #Spicerparts #warn #rockkrawler #rebeloffroad #bruiserconversions #magnaflow #warnindustries #teraflexsuspension #factor55 #jeepin #BFG #foxshocks #67designs #je_reel #pscmotorsports #proeagle #Ruggedradios #4x4spod #steersmart #RockSlider #Gladiator.gang #bajadesighns #offroadcustomz #sincitydieselandoffroad

Fire breather we did some earlier pulls we have 571 rear wheel little over 700HP at flywheel ! For everyone to understand we at Bruiser have been hearing some rumor so let’s get the information correct . But we will ask nicely for this person to get her info correct. That statement was that our conversions have a different firing order which is not true with making the timing to be off Bruiser has several different applications but 75% of all of our kits run factory LS base engine’s and accessories drive assembly from GM with a E38 and a factory firing order. #jeep #jeepporn #Spicerparts #warn #rockkrawler #rebeloffroad #bruiserconversions #magnaflow #warnindustries #teraflexsuspension #factor55 #jeepin #BFG #foxshocks #67designs #je_reel #pscmotorsports #proeagle #Ruggedradios #4x4spod #steersmart #RockSlider #Gladiator.gang #bajadesighns #nitrogear
