Has anyone tried non-automotive diesels? I tried a search, couldn't come up with anything, but yanmar, doosan, etc. (a lot of generator manufacturers) all make several engines that would fit in almost any FJ40-100. Everything from a 1 cyl. to V-16 From what I understand, most can be ordered to mount up to any SAE or metric bell housing and they all come with alternators already mounted. Is this incorrect or too much fab work? Just a thought as a fella I used to work with is a generator guy, (mainly onan), and I was going to see what was laying around his shop. I thought about going with a cummins but a brand new yanmar 4-6 cyl. turbo can be had pretty cheap. This will be going into an 80 so I have room to play but my thought was I could mount one of these in, fab an adapter flex plate if needed and keep all toyota guts the rest of the way back. how far off base is all of this?
