if i were you i would put a different toyota diesel in there, the 1KZ-te is a 4 cylinder diesel that are placed in hilux and prados. check out the inline 6 cylinder diesel's in austalian landruisers. they would fit nicely into the engine bay of a 40 landcruiser, there are many companies that specialize in toyota diesel engines, tranny's and halfcuts. good luck!!
