I encourage you to do the search on this board using MPI conversion, FI conversion, 4.0 conversion, etc. A growing number of us have done it the hard way, that is by taking most from a donor vehicle. The hard part transer is not the problem, Oh, it there is plenty of work in that part also, but the major issue comes in the wiring from the donor to the destination vehicle. Again, there is much in previous discussions on these topics.
