1979 Mustang 2.3L. How do I Swap From Carb To EFI?

hi there,, i have a 1979 mustang, 2.3ltr...the motor has a regular carb setup.. the motor is a rebuilt turbo engine but no longer has the factory stock turbo which sucked for 1979...i would like to convert to fuel injected, but dont know where to start, do they make a conversion kit with intake manifold, injectors, throttlebody and controls..if so then where do i get it.. thanks for any help i get...79' has 200,000 miles and still going great...

need help switching from carb setup to efi

hi there, ,im a newbie to this site, so i have a question..i own a 1979 ford mustang , 2.3ltr , two door hatchback.. it originally came with a 2.3 turbo carb setup, but for that year it wasnt all that great..the turbo blow out in 97' so i put a turbo 2.3 back in it but without the stock turbo. now its just a 2.3 with standard intake manifold..my question is , how hard would it be to change over to electronic fuel injected..and if there is a bolt on kit that i can order from someone like jeggs or other manufactures...and im hoping the kit would come with everything, like manifold, injectors, throttlebody, and computer control. so if someone has an idea please let me know..the set up im got now is still running good, just very limited on power upgrades.. over 200,000 miles and still going..

You're gonna need just about everything out of the engine bay of an 88-'90 4 cyl. EFI car. That includes the engine wiring harness and all the wiring that goes to the computer. It's gonna be a fairly big job but it can be done. You'll also need the fuel pump, fuel lines, and quite possibly even the tank. You'll also need the electric fan, relay module, and the distributor w/ignition module. There isn't much that the EFI cars have in common with their carbureted ancestors.

My advice would be to locate the parts in a junkyard, i don't think there are kits for the 2.3L

Hope someone has a better answer, good luck

There just isn't enough demand for the 2.3 EFI stuff. The guys who race 2.3s run carburetors (on converted EFI manifolds...go figure)

If you can get your hands on the factory EFI harware(injectors, manifolds, throttle body, etc.) You can run a Megasquirt engine management unit or one of the other more expensive alternatives.

So the reason you only got one reply is the fact that there is only one reply.

You'll need the fuel pump hanger and pump, fuel lines, computer, harness, all the sensors, the upper and lower intake manifolds, the exhaust manifold, the A/C components (if yours is an A/C car, the newer car's A/C tells the computer when it is and isn't on so the computer can compensate with the IAC valve to keep the car from stalling).

You could run an offenhauser 4bbl. intake manifold with an aftermarket Holley or Edelbrock 4bbl. EFI kit, but that would likely be more expensive.

I think there are companies that build kits for FI convert. COuld probally change a carb into a TBI setup.
The FI 2.3 has more hp than the carbed one so i think doing a custom TBI setup on this 3.3 I want if it'll give it more hp
