Dipstick wasn't dry but it needed a lot of oil even though I got a change 2 months ago. Would it be better to rebuild the IDI or swap to a Powerstroke? If swap, what complications could come from it? Could I use the ATS turbo on the powerstroke to twin turbo the powerstroke?
Probably did seize if it needed a LOT of oil. As far as rebuilding the IDI or swapping a powerstroke in, its just really a money issue. And what you mean by "better", like cheaper, more powerful, etc. You would require A LOT of powerstroke parts, but your zf-5 should work. I doubt you could get the ATS in there and run sequential turbo's, just not that kinda room. And running parallel turbos requires A LOT of fab. The only complication from swapping in a powerstroke would be making sure its done right. It would actually probably be easier to swap a mechanical 12v cummins in, just because they're so straight forward, and have no electrical crap. just my 2 cents.
