2.8 fuel injection/ throttle body ???????

[1989]

i was reading in the teck library that you can do fuel injection for a 2.8 but the page isnt very spacific so i need a little help understanding it am i replacing the 2.8 with the 3.8 from a cougar or am i just useing the fuell system and wireing harness because it says to remove my motor and to me it seems like a lot of work to remove the motor just to install the wireing harness and fuel rails?????

When I did mine....

And when we did it to my dads truck, it has more details on how to do it.

I will note that none of the truck have them on it now due to over fueling issues. We didnt have the time to tune them so we just durasparked them. But if I were to do it all over again, and could since I have both the systems, I would go wit the 2.9 wiring harness and computer. Only thing with that is you have to run all the stuff that the 2.9 computer touches. I was running a 2.3 tank and pumps and my dads setup was running a plastic tank with just a single in tank pump that came off a gen 2 ranger that was running a 2.3 also. The 2.3, 2.9 run the same pressure, but as long as you keep the pressure at 44psi (ford factory) then you should be good. Only thing with the 3.8 is the computer doesnt know its on a 2.8 and the injector pulses were to long and they were being opened up to much hince the over fueling issue. We tried a fuel pressure regulator and they didnt work to well. Since the 2.9 has a batch fire setup, just hook the 2.9 wires into the 3.8 TB injectors and you should be good, since they are hooked together anyways on the 3.8 from the factory and both open and close at the sametime.

And one thing that I never got to do or look much into was putting the GM 2.8 setup on a ranger, let alone if the wiring and whatnot could be done or just the TBI unit could run with the ford wiring since the injectors are the correct size for what a 2.8 needs fueling wise.

There is a gentleman over at broncoii.org who is swapping on a gm 2.8 throttle body on his 2.8. Here is a link to his build.

I wouldn't go so far as to call me a gentleman!

Thats what I was going to do but I had to get my truck running in a pintch so had to do the duraspark setup. Now If I wasnt going to do the 302 swap, then I would try and go do this again.
