How to wire a tfi distributor in carburated car??

Just wondering if anyone knows how to wire in a tfi 1986-1991 [eg] 302 Truck,Mustang etc..distributor in an older carburated car.i have quite a few of these kicking around and would like to make use of them if i could.Derek.

 

Don't they require the computer to operate them?
The computer would then expect to see feedback from many sensors to determine timing.

yeah i would almost bet a computer is needed to run those but i am NOT sure


whats wrong w/ you dizzy now?

 

They do not have any way to advance/retard timing.
That is all done in the computer.
Without that input, I am sure you could get it to fire, but the timing would be totally static throughout the rpm range.

 

You could probably wire it into a Chevy ignition module, but I don't think it would run right since you would always be stuck at base timeing. Duraspark II distributor or Pertronix would be the best. ebay the TFI distributors.

edit: damn you guys are fast.

 

It is possible to make it work. Is it the right choice? No. There is waaaay too much wiring and modification needed to make it work. If you have to go through all that trouble to make a TFI work, might as well add a few sensors and have EFI. Better yet, go with a Megasquirt and build/tune your own EFI system using that TFI distributor.

 

The main reason i was asking is that the wifes 1984 Crown vic has a cfi unit on it [carb with injectors] and it is really messed up and i want to put a 2bbl on it and wanted to know if i could leave the tfi dizzy in it with the carb set up.Wiring in a duraspark is no problem i just wanted to save some time if i could.I also have a few more injection to carb conversions to do and thought i might be able to use up some of the newer distributors.Derek.

 

:hmm: never herd of CFI

 

I think you could make it work....

 

sure anything can be done with a torch and a welder


well in this case , wire , tape and a schmatic(sp)

 

You cannot use those distributors with a carb setup.
Converting to carb MUST have the proper AOD hardware and adjusted correctly or you will lose the transmission.
You will end up with more problems than fixing the existing problems.

 

AOD throttle pressure kits are available for most carb installations. If the car is for the dragstrip only you can set the initial timing at 36 and it will not adversly affect the engine in any way. You wouldn't want to do tha for the street because of the varying load and throttle conditions.

 

CFI is junk! But....when you do the conversion, save the injectors. Just bust out the top of the throttle body that holds the injectors down and pull them off....and sell them over at turboford.org. They are big injectors, probably 42 lb/hr. 4 of them on a turbo 2.3--capable of supporting close to 450 HP and believe me, those guys can make that much and more.

Anyway, converting from CFI to carb is easy. The manifold is already a 2 bbl manifold. Just pull the TB off and put a 2bbl carb on there. Then the distributor issue (easier to go with a Duraspark unit) and the fuel pump issue. That car MIGHT have the dual pump setup on it; a low pres. pump in the tank and a high pres pump on the frame. If it does, just eliminate the HP pump and it will work fine with the LP in-tank pump. If you go with a 2 bbl carb, even the AOD linkage will bolt up, IIRC.

 

Looks sort of like a 2v carb with two fuel injectors in the top. A 2v carb even bolts on in place of it. I converted an '85 Lincoln to carb a while back that was CFI.
