Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello, Eddie here and I will try to help, What size engine do you have in it now? 5.8? or 5.0? These Bronco's (Big Bronco, not Bronco II) they never got good gas mileage.
The short answer is yes, it is possible, however, You have to get the entire wiring harness, from whatever donor truck/suv you get it out of, including the PCM (engine computer) and the transmission as your transmission would not be compatible with a PCM from a newer vehicle like that, So it can be done. but it requires more than just a routine engine swap. Is this something you would do yourself? or do you have a shop that you are considering for this job?
Alright I understand. The swap can be made, however, for that extra 4 miles a gallon, I really don't know that the expense warrants it, unless your engine is defective and you were going to swap it anyway of course. The entire wiring harness, all the accessories, the PCM and transmission need to be swapped as well to really get that gas mileage that newer cars are getting. It may even require a new gas tank and some modification there, as your fuel pump puts out about 30-40 psi and depending on what year engine your donor comes out of, those engines might require 50-60 psi of fuel pressure, There really is more to consider than just the engine swap alone, but those are the main things you would be looking at. Let me know if you have any further questions on it. Thank you.
