200 to be EFI with your help

Hi everyone.
Im thinking of making my 68 200 EFI using a Throttle body. Im not very savvy when it comes to efi. My first question is are there any Throttle bodies that will bolt right on to my stock head, or bolt on with VERY little fabrication? It has a holley 1940 carb on it. I read somewhere people use TB's from taurus 4-bangers, does that bolt on to my intake log? also would it be big enough for a stock 200ci?

Are there anyother TB's you would recomend i start looking for instead?

i plan on running a megasquirt with it too. what is the minimum requirment of electronics to run a megasquirt, only controlling the fuel not the spark. Other than o2 sensor, throttle position sensor and temp sensor?

Any other information to do with efi would be greatly appreciated.

Thanks!
Moe.
 
A simpler solution might be to pick up a throttle body with the injectors built in, rather than having to fabricate the bungs on the head, if you're looking for a bolt on solution. I've toyed with the idea of the Holley Commander 950 throttle body but you could probably wire it up to a megasquirt to save money rather than using Holley's controller.

Shouldn't pretty much any 2V style TB work? I'm sure there are plenty in a junkyard.

Yes, much simpler. A Megasquirt can run 1 or 2 injectors on a TB easily.
 
I was trying to think of reasons to pay Holley the money that they think that's worth when I could take one off a Chebby 305 that does the exact same thing, and probably even has the same base.
 
Was only trying to show the tb with injectors as an option to linc's original link to welding injector bungs onto the head. And clearly new parts are going to cost significantly more than junkyard.
 
Oh, thought you were endorsing them. I'd rather scrounge for stuff than buy new if I can, because I am broke :wink:
 
69Falcon -- The holley's are too expencive for me. Do any TB's from production cars fit on my intake?

wallaka -- what do you mean by "2v style TB"? do you think you could givbe me an example of what kind of car has that style of TB?

Lol, im realy just looking to find out what TB will fit directly on my engine, or one that is very close to fitting. I dont have access to much mechining equipment so an adaptor would be fairly hard for me to make.

Thanks for replying guys!

a ford CFI unit from a 3.8-4.2-5.0-5.8 will bolt on a clifford adaptor.

the reason I am going with the port injectors is this.

1. got the injectors fairly cheap (35# low imp)
2. opened up the log for more flow
3. have been having good luck welding on FE
4. something different

I am thinking NOTHING without machining or some adapters.

....and then there's the throttle linkage...
 
"I am thinking NOTHING without machining or some adapters."
dam, was hoping one would fit. What TB off what car do you guys think would be the simplest to get to fit?

Cable, easy peasy.

Not all TB's have the right hook-ups, though. Some have a ball and some a pin.

On some the geometry is designed to pull down to open,
some up,
some left and some right. Not so easy peasy now. I have a 4.6 liter TB I'd like to send to "turbo_fairlane_200" and by looking at the bellcrank/arm I am 100% certain he would need to weld something on it to make it work.

Ummmm.......Anything that will bolt to a readliy available adapter.
 
Transco 2044 from Summit should fit, and just run the so-called horiable old Motorcraft CFI unit from any 5.0 1984 to 1986 LTD/Marquis or the V6 item found on 3.8's. Fix the Ford technical bulletin service items, and go for it.

The control unit is EEC 3, so you'll have to shop around for a contoller from Megasquirt, or butcher the sensors to run on your six cylinder engine.

The key here is getting a good, simple system.

Stock, they fueled engines in the 115 to 140 hp area, so they make the best swap. Blue Injectors are very high flow, they have no return line on early versions, and run a nice simple electric fuel pump.

It's about time we got some of these CFI Ford 200's running! The gear is there, its just no-one has done it yet. It's doable without making any custom parts!

1) V 6 cars had about 36-38-40 lb per hour injectors (or thereabouts) and the V 8 cars got good ones, around 50 lbs per hour or so?
 
Nope, the V8 ones ran at really low pressure, and were much bigger, about 483 cc/min from memory, at about 25 psi or so. They are the same as some of the 2.3 or 2.5 HSC CFI items. Somewhere here, an Aussie guy listed all injectors, high or low impedience, on a PDF file about a year ago. That's when I checked it all out.


:idea: Ford got smarter, and realised that its cheaper to get stock Bosch style injectors, so the Blue ones in a 3.8 are a hot ticket for a hi-perforanmce six.



Hey Linc, why not just slap on three of these on an Offy Intake, and run three of your 3.8 CFI's and some forged pistons, turbo it, and go for 10 second quarters.?

Oh yeah, ordodraconis. This dude has the most basic kit around, but dang its a goodie for every dollar. Check out this ( http://fordsix.com/forum/viewtopic.php?t=37872 ) in the Big Six forum. He has has shown us his 2-bbl 2100 to 2044 TransDapt kit, and I really think a good CFI unit would like to sit in a little 200 I6. The engines are so shallow, the CFI has no air horn or choke, and would look like a weapon plished up with a Speco velocity tube.


Man, these CFI things are cool!


(I know the 2-bbl to 1-bbl port area isn't perfect, but niether is the flow characteristics of a throttle body EFI. Adding a 2044 adaptor would probably re-introduce the fuel air mix into the air stream better than a 2300 Holley or 2100 Autolite in this situation. Ford did it with some sucess when using the 5200 HW on the 2.6 and 2.8 V6's in the 70's, and it worked better with the adaptor than without)

I'd drive all the way to Argentina to get an alum SP head before I pulled a stunt like that.
 
Heh heh heh. LOL.


Hey, how much for a bushel of 3.8 CFI's. Half a dozen maybee? Could you give me a good price! I'd love to shove three of them on my project engine!

well linc I am up for a drive.

I picked up my project head from the shop at the uni yesterday. man those welds of mine look crappy. I am gonna have to reweld it up back at home I think over thianksgiving. buddy gave me a 3.8L GM TB and was messing with it and I think we can get it working on my boat ancor pretty easy.

I thought the eec3 stuff was REAL hard to find as it was only used for one or two years (most the other cfi cars where EEC4)

granted it has been tempting to get an aussie dizzy to toss in my 170 and put a cfi setup on it.
