Late model ford efi on a 390 FE

Got a question. Could I take a fuel injection system off of a 2000's mustang gt and use it on a 390 BBF? reason why is I heard the aftermarket has a tuner that you can adjust the computer to meet the air/fuel needs if you decide to up the power.

I want to use everything except the intake manifold and throttle body. I know they won't fit. I want to drill my manifold and weld the injector bosses in there.

Can it be done? or am I talking crazy.

.
What parts would you use then?

Holley and Retrotek have throttle body injection kits that would work. They're about $1600. Probably a lot easier than what you have in mind.

What is your goal for the conversion? I have specific suggestions depending on your use.

Yes you can. It'll take some custom work and patience, but it'll work. You'll also need the $600 TFI Distributor from Mallory.

MY427STANG, Ross, just did this to his 489 CI FE engine in his Mustang...

Ask him what he did and the results...

Re: Late model ford efi on a 390 FE

The GT system (depending on year) would use a toothed crank trigger rather than TFI, so other solutions may be more appropriate. As Gary says, it could be made to work, but I think there are better, easier, and less expensive ways to hit your goals than bending this system to fit. Let us know what you're starting with (post above) and we'll do some brainstorming.

Damn - I really need to make a simple economy EFI conversion package for early Fords...

Re: Late model ford efi on a 390 FE

Last summer I dropped a 392 (SBF) into a 1996 mustang, and running a BBF off of a EEC-V based CPU (1996-2004) is definitely do-able. It's probably going to be more work and more money than you want, though. Here's the major issues:
1). You need a crank trigger wheel with crank position sensor (not a big deal, but it usually takes a little custom machining of the crank trigger wheel to get it onto your crankshaft pulley).
2). You need a camshaft position sensor. I made one by doctoring up a distributor. Ugly, but quick and effective. The only other way I know of is to custom machine the crank position sensor out of a late model ford explorer. There never was a CMP sensor for a BBF, so you'll probably have to go with the "doctor the distributor" route here.
3). You need an EFI intake manifold for 8 fuel injectors. Edelbrock, and few others make these for SBFs, but I don't think there are any for BBFs. You would need to take an existing manifold, and have it machined with bungs for fuel injectors. Probably a couple hundred for this.
4). You will need a very custom tune. This means that you will need to buy a handheld tuner, and learn a lot about the EEC-V (the route I went), or you will need to spend some quality time with a tuner and a dyno. This will be quite a few $$$ either way.

If you really want to go EFI, I'd avoid throttle body injection. In my opinion it doesn't really offer many advantages over a carb. It's a little more adaptable to widely varying weather temps/conditions, but I don't think it's worth the extra $$$.

If you have your heart set on EFI, I'd suggest trying to get a EEC-IV (1984-1995) based computer. The ECUs are pretty easy to find, and the programming tools are simpler and less expensive. You will still have the intake manifold issue to work out. The only reason I didn't go this route is that I had to have a OBD-II compliant EEC-V computer to pass emissions.

Re: Late model ford efi on a 390 FE

I was going to leave this alone but damn its pissing me off, first off it is not a BBF which if there was it would be a 370/429/460 but he has a 390 which is known as an FE.

Also I had Throttle Body Injection on a 390, and guess what? It was freaking amazing but me being a dumb ass kid didn't know any better at the time because I was too retarded to trade down a bad ground.

Anyways TBI is a decent way to go lets look at what you get out of it.

-Somewhat Increased MPG depending on what carb you have now what TBI setup you have and what type of driving you do.
-Better drive ability in the cold on par with any modern fuel injection system
-Can be setup with coolant temp sensor, spark control and o2 sensors, more accurate control over how much fuel is going in the engine.
-Oh yeah its cheap you can get a good used unit much cheaper and easier then it would be to adapt the fuel injection stuff from your mustang to your truck.


He asked in the first post can it be done? Yes it can. If your not using the intake and throttle body(cant anyways) you want to know what else can you use.

I imagine you could use part of the fuel rail, injector harness, injectors, ecu, fuel pump possibly, not much more after that, and even then it would be very expensive.

As far as injection goes the first stop on the EFI train that is cheap and easy is TBI, next would be EEC IV from a 86-93 vehicle.

94+ is EEC V and I have not seen any v8 from ford pre 1986 with multiport EFI, may have those variable venturi carbs from the 80's but they are crap.

Anyways its alot of work either way, the TBI I am a fan of can be bought for about 1k or used starting at about $100 and going from there depending on condition and such.

Just to save you boneyard hunters some pain, this isn't 100% true.

1994 is the first year that EEC-V appeared. It was only in some Ford cars. 1994 and 1995 are transition years. I don't believe all ford cars were EEC-V until 1996. V8 Mustangs aren't EEC-V until 1996, for example.

Re: Late model ford efi on a 390 FE

Well I thought he was wrong about that, just looked all of my 94 ECU's are EEC IV but some of my 95's are EEC V but some are IV the ones that are V are from CA it appears. Dont have any 94's from CA
