'747 + 6 Cyl + Turbo?

[chetwagner at uswest.net]

Just to let you know, I did put EFI on my 77 FJ40 Cruiser with the 
2F engine.  If you have questions, let me know.

Poly from which I've learned some useful things that will apply to this project. I'm not babbling this info to try to qualify myself, but to shed some light on my background so you might be able to answer some questions I have (if you might be so kind :). The project is as follows:

> My current short-term goal is to simply install a throttle body/'747 system from a 4.3l GM truck or van. In the beginning I just want it to work well enough to drive around daily. Question: Do you suppose re-programming of the ecm will be neccesary? I assume the system would run without any 
mods due to the similarities of the engine displacement, but I don't have any idea of how well it might run.

Is this feasible for a non EE like myself (I have programmed in C and other lanugages though and have a grasp of basic electrical concepts)? I would rather not fabricate a new intake manifold for port injection, that's why I picked the '747.
