Working at an off and on pace, I finished it up in about three days. The only hard part was cramming the wiring behind the center console area (very tight but a coathanger helped a lot). I used:
1) your typical A9L computer $100
2) 1994 taurus/sable 3.8 mass air meter $23
3) a 50' spool of 16 gauge wiring $7
4) package of assorted heat-shrink tubing $10
5) A mass air kit from tunable induction w/ filter $117
I also had a lot of use out of my soldering gun with all of the wiring.
Number 5 really doesn't matter but for me it was one of those oppotunity things, plus I needed a new filter

- but as you can see it was very cost-friendly.
