Default Efi

I'm starting to think about my next mod, and that would be electronic fuel injection. Professional Products has a throttle body system that looks nearly foolproof, Powerjection III. Remanufactured kits are about $1100. I figure another 2-300 for supply and return lines and their fuel on demand module, which would reduce the pump noise at idle. Not really sure how I would install the return on my existing tank though.

This won't be for a while, as I need to iron out some other issues and let my wallet rest a bit. I'd like to know what others have experienced with these systems.

I intended to install an oxygen sensor in the exhaust to help me tune the carburetor, and I actually have one with a bung to weld on when I change out my mufflers. But I'm afraid my old carburetor isn't long for this world. The E85 gas is probably eating it up; as I'm experiencing really poor fuel mileage.

Instead of buying a new after market carburetor I'd rather spend a little more for better starting and driveability.

I just looked at a youtube video about that system and the guys says $1650 to $1750 to get it up and running but that's a pretty good price considering the Holley EFI is about $2300.

Default is about the only good vendor who KNOWS EFI systems. You should talk with them.

They sold me a unit, made by a company who ONLY makes EFI systems. FAST (Fuel, Air, Spark Technology). I looked at Holly, Edelbrock, MSD, and many more. Then, I bought a FAST Fuel Injection EZ-EFI Self-Tuning Fuel Injection System.

The price depends on what components you need. If you have a programmer or an electric fuel pump the price drops dramatically.

When I install it, I will post pictures. - Dave

The price also depends on if you get a remanufactured unit. Pro products advertise these on their site for about 60% of new.

Dave, why did you choose the FAST system?

I called their tech line yesterday and talked to "Cole". He knew slightly less than I did, apparently, as I could hear him flipping through pages of their catalog trying to answer my specific questions.

I told him that I liked the compact design of the Professional Products Powerjection III so he said, yeah that will be good. Then I expressed concern about the electronics being mounted directly over a hot cast iron manifold and there was silence.

Then I told him I liked the lifetime warranty offered by FAST and he flipped through some more pages and recommended the FAST EZ-EFI 2.0, which is 8 injectors (two in each venturi).

I think that is overkill for my application. The FAST EZ-EFI (1.0) is less money and can still support 200 more HP than I have.
