He's absolutely right. Don't butcher a perfectly good 5.0 Mustang just because you are electrically challenged...

For free automotive electrical training, see Automotive Training and Resource Site . I have personally reviewed the material and it is very good.

A word of warning on EFI to carb swaps: don’t expect to pass emissions in any state that does comprehensive smog inspections, because it won’t happen. Some states will not title or issue license plates to cars that have been converted from EFI to carb. Be aware that you are violating several Federal laws concerning the removal of pollution control equipment. If you operate the vehicle on public highways and get caught by state or federal law enforcement (doubtful, but possible) you could be subject to fines and imprisonment. You won't get any more power from a carb than you will from EFI.

Some of the motivation of my negative comments about carb to EFI has to do with the quality of electrical workmanship. A lot of the wiring “repairs” that I have seen on the road and in the junkyard looks like road kill. The other part of my negative view stems from people who can’t grasp the operation and tuning of EFI. Carbs have their own set of requirements and some learning is required to get the best performance. Every car is different and each installation needs to be tuned to get the best performance. Putting an “out of the box carb” or one from someone else’s car isn’t the way to success. There is no auto compensation for small variations in carbs like there is for EFI. Just throwing a carb on a car because you won’t bother to learn how EFI works is a poor excuse.

I agree.

Incase you still want to got Carb

EFI to Carburetor Conversion

Gene

For a street car, stay EFI. Search Ebay for the harness needed, there are several available for a lot less than new carb, new intake, etc. would cost:

Im all for stayin efi, but that is an awesome write up for doin the conversion haha

As for the wiring, I just pickedup a full body harness out of an 89 GT for 250 dollars, and I got the computer harness, 02 sensor harness, and injector harnessfor 75 shipped to my door.. so it would def be cheaper and a lot easier to just replace the wiring harness that is giving you troubles..

i went carbed and love it,but the again i like old school.That's just my 2 cents

Counterproductive.

Look online, if the ecu harness is all you need, you should be able to find one pretty easy

I was toying about going carb, but chose in the end not to. The way i figure it is, either way it will have to be professionally tuned. The tuning systems are expensive and I am not going to waste a good motor trying to do it without a dyno. I do wish there was an affordable, easy efi software to use.

i agree with going carb bc its simpler cheaper and easier to fix, but all you need is intake carb 85 mustang 5.0ho carb distributor, and a duraspark box, and low pressure fuel pump its very simple, just pull the ecu and complete harness out, i went carb and never go back, you can do whatever you want to without a tune or anything, also you will need to drop your tank and pull out the intank pump, if your near va pm me for exact details, my engine bay looks so much cleaner now, but thats just my two cents as well.
