Re: 1998 Jeep Grand Cherokee turbo diesel
You need to consider just how much work your willing to do. Most of these options will work with massive fab work and wiring.
The 4BT can use the 6BT rear plate. They Jeep can fit the 6BT trans. That leaves fuel and mounts and the little stuff basically. The 4BT can be turned up like my 6BT, super cheap and easy. Then like the 6BT run for ever. Shifting a diesel is great pulling a trailer, sucks big time for speed. I don't care who you are, I load up the turbo and hammer it and go right through the gears. A stick = slower truck unless really towing weight, a Jeep doesn't need to pull 20K so I'd think auto trans.
I also don't think the weight between a 4.0 all iron and a 4BT are that far off. The 4.0 is really heavy lol.
So again I'd really think about how much time your willing to spend on this, 4BT auto is the fastest way to a diesel Jeep.
