Cummins 4BT

cubanchris81 · 11-19-2009, 12:51 PM

My goal is to install Cummins 4BT diesel engine in my 98 XJ 4dr. I'm liftin 6.5" RC lift this year frame stiffners & removin/replacin any rusted away metal. I know heavier springs, stronger motor mounts & strengthening unibody with a complete subframe will be needed for weight of new engine/trans & torque but hesitant on what transfer case & transmission I like Teraflex's HD 231 4:1 ratio 29 spline t.case & would like to buy this year with SYE for lift but I don't know if its strong enough for 4BT or if will work with dana 44 high pinion full floating axle assembly front & rear & new tranny that bolts up to 4BT(unknown right now haven't gone down & talked to dealer yet). I'm askin if you guys know/heard of a combination that someone is runnin with 4BT tranny & transfer case
