you're reading way to much into it...

the '99 7700 series F-150 probably has a NPI motor in it, and if is a PI motor then stop reading so much into the swap unless you really really want to spend WAY TO MUCH MONEY for nothing to show for it.


PI and NPI motors use the same ECM, to make things simple for you, IF you find a PI motor then use the NPI to PI adapters that HPs offers as that will be a lot smarter for your money so you can use your current intake manifold and wiring...

 

[QUOTE=tarajerame;4465400]you're reading way to much into it...

Im not trying to "Read into it too much" im just trying to get as informed as i can before tackling my first ford engine change, there are very limited options in "Kawartha lakes Ontario" boonies are hard on trucks, so either they have 300,000-500,000 kms, are thousands of dollars, or still in use, i dont want to buy something and figure out i just have to drop a pocket load of cash on it just to make it work as i am in college with Very limited money to spend.

There are NO f150's with the romeo engine available that i have found, so my only option for a romeo would Possibly be out of a car my problem is i have no clue what im looking for, how to tell what it is ect. So my apologies if im being irritating, but ive owned this truck for about 3 years now and its been sitting in a garage waiting for me to get to it

i need someone to basically Draw out the line of what i should be looking for, for the easiest swap in without having to change anything Durastic given the limited Romeo availability

Again, Sorry if i am being irritating. Just frusterated

 

I hope the explanation I have given you is sufficent. It is not a big deal to swap out a Romeo for a Windsor. Just follow our direction and you'll be fine. Find a Windsor between 97 and 2000, pull the Romeo engine stick the Windsor in and use everything that was being used with the Romeo including the ECM. Use the Windsor intake or the Romeo, truck exhaust manifolds, coil packs, Romeo oil filter adapter, Any other questions just ask. Good luck.

 

What is the difference in wiring on the intake on the windsor and romeo? is it stupidly over complicated? or can just the throttle body or something be changed to save the confusion

 

On a non PI Windsor and non PI Romeo there is no difference. The only time you will have one or two differences is if you go non PI to a PI engine and I explained that above being the extra coolant temp sender on the non PI. Also I change the throttle body using the non PI to the PI intake if it is that kind of swap then the vac lines will all hook right up. This is definitly not brain surgery. Basicly Romeo engine out Windsor engine in.

 

it's not the throttle body or throttle body elbow or ecen teh exhaust manifolds, and the NPI manifolds will interchange same with the PI manifolds...


what you need to do is decide on what route you are going to go then we'll help you make it thru the swap IF you are willing to pay attention

 

I agree tarajerame make the swap and the rest is just a matter of routing and connecting. The only reason I mention exhaust manifolds is in case his replacement engine came from a car then he needs to put truck manifolds on before installing the engine, Also I swap the non PI throttlebody over to new engne intake if it's PI because they went with the heated vac system and it makes it easier to just reconnect everything. I may be confusing him more than helping, not sure...

 

found a cheap windsor, so im going to be going that route, 220,000 on it he will pull it out along with anything else i need for $300

 

Good luck, any other questions run them by us.

 

Hello to all,

My son has a 97 F150 4x4 with a 4.6L romeo engine in it. He has acquired a 4.6L Windsor engine from a 2001 F150 2 wheel drive truck. Will this be an easy swap? or is there going to be issues with wiring harness compatibilities? Any help here would be greatly appreciated. Thanks!
