build up plan
I'm about to finalize by parts list for my cummins build up on my 88 YJ and wanted to bounce my idea off some of you to see if I missed any thing.
We'll start with the engine, it'a a 3.9 cummins turbo diesel. Its rated at 120 HP. It came with a chevy automatic transmission adaptor. I'm attaching a 700R4 with a diesel convertor for bottom end grunt.
For a transfercase I'm going with a NP241-C. It will need a super short SYE so I won't have to attach the transfercase to the rear diff. I will order JB Conversions Super short kit.
For Diffs I'm going to go with a Ford 9 inch in the rear and a Dana 44 in the front both geared at 4.10, out of a Bronco. I plan on a spring over when I install them so the lift for the 33's won't be an issue.
Once I get the drive line mocked up I can measure for drive shafts and exhaust. I know I will have to get additional springs in the front to accomadate an addition 300 LBs of weight(engine and winch). I'm going to tilt the engine and leave the tranny flat for ground clearance on the transfer case
Any comments or concerns will be gladly accepted. Any good leads on parts that I may have overlooked please PM me.
