1992 F-250 Extended Cab Long Bed 460 to IDI Conversion

[Ranch_Ford]

I've been looking into the idea of converting my 1992 F-250 Gasser to a Diesel, I needed to know if any other components will need to be changed over? or if I can just bolt it up? I plan to run a push button for the glowplugs and a shutdown switch to the Injection Pump. Will the 460 ZF5 trany bolt to the diesel or is there going to be problems there? I am not worried about the difference in gear ratios between the trannys that won't be a problem.

So any thoughts?

You will be best off to have a complete doner truck as there are always things you dont for see needing

x2.... find a donor truck. there is a lot of stuff that you might need that will cost a bunch, that or find a good ol' 12v cummins.... but the tans adator plate might be a bit pricey, and engine mounts too. just have to look around and figure that out. I jsut got done working on a ide, and I must say, easy to work on. No valve covers to take off to replace GP's or sticks!!!!!

No need to run a "shutdown switch", all you have to do is feed +12V to the fuel pump from a wire that is hot-in-run. Then your key switch will work like it's supposed to.

Your tachometer won't work with the gas version of the dash board. You could probably run an external tach. There is a set of wires on the fuel pump gear cover that reads the timing gear. I think you can splice into this for a tach.

I'm in the process of doing the same conversion into an '88 is there any thing i need a heads up on?

the tranny wont bolt up directly from the gas engine, your going to have to drill some holes i beleive. Take a look at oilburners.net, there are quite a fw guys that know eveything about idi's over there.

I have a lot of the components left over from a truck I turned into a romper, so I pretty well have all the components I'd need from a donor truck. Like the Dash, Wiring and some odd ball components. I think I might do the conversion but it'll have to wait till I fix my main truck... Bent the pinion shaft off roading after I just rebuilt the rear end less that 3 months ago. A torch to cut the bent and warped pinion out and a few bucks later it's ready to be rebuilt again....
