Fuel managment:
For a control computer I plan to use the MegaSquirt System. It controls ONLY fuel injection and leaves ignition to your discression.

The MegaSquirt is plans and you have to build it yourself. One of my best friends that I went to college with is an Electrical Engineer working for HP in Vancouver right now and if I buy the parts he will build it for me. I will most likely be out the "labor rembusment" of taking him out for pizza and beer or something like that. A mega squirt can be built for under $200. The price range from about $132 for the basic and go up from there depending on extras and goodies a person may want.
Injectors:
For the injectors I will be using a TBI from a Chevy 4.3L V6. THese were put in the s-10, the Jimmy, the Astro van, etc, so they are everywhere and CHEEP. Used ones in good shape are consistenly selling on ebay between $30-50. And I am sure you could get one at a u-pull place pretty darn cheep!
Intake adapter:
Well Man a fre has an adapter for $100 BUT here is a guy who made an adapter and it is all done with simple tools and a drillpress, no machine work needed. Estimated cost $15! Now we are talking!

Fuel Pump:
Well these aren't too expensive. I want to upgrade the pump on my car and so I could use the old one. Otherwise I will get one off of ebay.
Fuel Pressure regualtor:
The Chevy 4.3 tbi may have a built in unit, still checking in not these run between $20-60 on ebay.
sensors:
Coolant and ait temp. sensors you can get these new for $8-10 each.
O2 sensors are $18-50 new but I have one already.
This is what I have come up with. Feel free to flame/critique my plan. There are still some details to be worked out but this is what I have done to date.
There is aparently a couple happy LC user of this system:

Estimated total Cost-----------------
Mega Squirt $180
4.3L TBI $50
Intake adapter $20
Fuel pump have used
Fuel pressure REg. $30(may not need)
Sensors $50
I figure I can have it all said and done for $350 this could easily go up but I don't expect it to rise over $400.I am such a cheepscate I may have it come in under $300 is I scrounge the junkyards and bargain hunt!
