Around 12 months ago I bought a 2000 Jackaroo (Bighorn, Trooper) with 4JX1 3.0 diesel. The engine had typical issues and with some help from this forum I ended up fitting a 4JB1 2.8 turbo diesel engine.
I have now documented the job and am making it available to anyone else who has found themselves in hot water with a Jack/Bighorn/Trooper and needs to ressurrect it. Send me a message and I'll arrange to send it to you in PDF form.

Im sure this user would like a copy

Thank you for the copy. But just want to know...Between a 4JG2 Isuzu engine and a 4JB1 one, which can be easily swapped in a 4x4 Isuzu Wizard 4JX1 turbodiesel with manual transmission ?

4jg2 or 4jb1 are going to be the same amount of work have to change g-box aswell as bellhousing is different
