I think that if the FI is in proper condition, it will provide better gas
mileage and performance than a two barrel progressive. But they can be
quite a bit more expensive to maintain and a lot more hassle than a
carburetor. My ex-girlfriend's '78 had FI when she bought it and it
ran pretty good for awhile, then developed a problem of surging/missing when
you were driving. You could be rolling merrily along and all of a sudden it
would start cutting out. Well, when you first confront the engine you'll
be greeted by a lot of hoses, tubes, vaccum lines, dashpots, etc. and (at least
in my case) you won't have much of a clue where to start looking. So the
first thing I did was become a FI "expert" by reading the Muir section and
checking out a couple of Bosch FI books from the library. After much testing,
I concluded it was the air flow sensor, a flap thing that measures the amount
of air going into the engine so that the computer can inject the proper amount
of gas. This one had a couple of "dead" spots on the wiper where it would
indicate a voltage of zero. This would explain why, when the engine was
misbehaving, speeding up or slowing down slightly would fix it. Well, I called
a couple of import parts places and the cost of this (and the cold start
injector, which was also not working) was close to if not more than the cost of
the Fast Freddy Weber kit. Keep in mind there were plenty more FI parts on
this bus the same age that might be breaking soon. So in one fell swoop, I
replaced all that hardware with one compact little carburetor! Voila, there
really WAS an engine under all that stuff! Aside from adjusting the choke
and idle, it ran fine right out of the box. We didn't notice any lack of
power, and she hadn't kept any close record of fuel economy but the carb didn't
guzzle gas, maybe 20 MPG. If your FI system is working okay, then you're
probably better off with it. And if it isn't, but you want to learn about
the FI system and have lots of money, then it's still okay. But if it's
broken then I'd recommend the progressive Weber. If you have fuel problems in
the future, troubleshooting time should be drastically reduced since (aside
from the filter, etc.) you just have one place to look (the carb). And if
you convert, don't forget to buy the little electric fuel pump. The one you
have puts out 35psi or so, and will turn your carb into a little Weber gas
fountain. :-)

Have you tried junk yards? Here in Indianapolis there are one or two that
specialize in foreign cars. Stuff like engines, lenses and emblems go pretty
quick, but other parts aren't too hard to come by.
