It's much easier to do this on a car that was originally FI and has the fuel 
return line. You'll probably want to flush out that line before you use it, 
however, because it's probably full of dirt by now, unless it's been capped.

Note that you have to have the RIGHT FI wiring harness. There were probably 
something like 6 to 10 different harnesses, and if you have the wrong one it 
won't work with the parts, or the car, that you have.

That's a hard choice. I know that if it were me, I'd do it, but that's because 
I have a basement full of the parts and I know exactly what's needed and where 
it goes. If you're not already familiar with the systems, this would be a real 

I'm not actually trying to discourage you; I just want you to go into this 
completely aware of what's ahead of you. I completely agree that it would be 
worthwhile to restore it.

As far as driveability goes, I think you'll find that both systems are very 
driveable in good weather. The FI has a small advantage in cold weather 
starting, but that may not be an issue for you. The main reason that the FI was 
introduced was that it could be programmed to produce lower exhaust emissions. 
That's probably not as inportant in your part of the world as it is where the 
population density is much higher, but we all share the same atmosphere and 
each contribution eventually goes into the same pool.
