Looks like a good list for engine mechanicals, but you're completely
leaving out the engine management side of things which is very common
when putting together this sort of project. Even assuming you could
get 20 years out of the rebuild(I would say that's a bit optimistic
honestly lower your expectation to 5-10 and you'll be much happier) if
you're wiring, sensors, and controls aren't also addressed I guarantee
you won't get anywhere near that figure for longevity on the engine.
You should consider what it is going to take to also bring those
aspects of the repowering into the picture, and make certain they are
all functioning to spec and will stay that way for as long as you want
them to, as without it your weak link will be engine management, and
endanger the entirety of your efforts. The three links are engine
mechanicals, engine management, and operator information. Any one weak
spot in any of those three links can ruin your chances of achieveing
your goals in short order. I wish I could offer you more specifics on
just what you need to consider in this regard, but there are others
far better acquainted with the bosch setup that you should be looking
to for input. Also keep in mind the old car-guy addage: Fast, Cheap,
Reliable, pick two.
