I have somewhat changed my direction from my previous post. I found a good deal on a lightly used FAST throttle body complete with injectors and sensors (the one from the EZ-EFI kit) from the FAST test dyno on ebay. So now I'm going to build a MegaSquirt-II v3.0 ecu and a wiring harness to control the throttle body.

Definitely labor intensive, and still not cheap, but I hope to have ~$1,100.00 in my system, and the ecu will be fully programmable, easily modified in the future for whatever I want, it will control the ignition timing, and includes a real time barometric pressure correction. Plus I hope to learn a TON about fuel injection by building my own system.

Using a megasquirt type system and junkyard TBI parts, you could probably inject a motor for $500 or so.
