I am planning an engine swap and having a hard time deciding between a Cummins 6BT and LS3. Currently I have a '97 FZJ80 with 2.5" OME list; heavy upfront, medium rear with airbags. Running 285/75/16 (almost 33's). I do not want a larger lift. Plan on keeping 4.11 gears.
My current rig has the stock engine (1fz-fe) with 197K miles, no oil leaks, 2007 rebuild. I just need more power. If I go with the 6BT I will source a A442 (bus tranny) as I heard it is stronger than the A343. If going with the LS3, I am considering the 4L64E tranny.
My questions associated with the 6BT are:
I have read numerous threads on diesels and the concern about blowing the Toyota tranny and breaking axles, blah blah blah. I like what the 6BT has to offer; mainly concerned about weight. I do not want to get into swapping 1-ton axles and other issues.
Towing a travel trailer (14-foot; 2,800 lbs dry) is planned for the distance future.
Please PM so we can discuss how the 6BT handles on trails and up the passes. I prefer to talk via phone. If you PM me we can swap phone numbers.
Thanks.

My questions associated with the 6BT are:
- How does the 6BT drive up Molas and Coal Bank? It would be nice to drive up the passes at posted speed limit with a some more power to spare.
- How does the weight of the engine handle on trails like Pougheespsie and Immogene? I am concerned about the weight. Especially with my TJM bumper and winch.
