Hello all!

Just sold my ranger, bought a 95 f150. (Great choice imho). Trucks got everything I could ask for! (except a good engine, it has a spun bearing, she runs, but - haha), but I got it for a steal.

I also found a 1993 5.0 Engine, with MSD Distrib and plugs for $100 complete from intake to pan. Can't pass that up either.

I'm looking to put the 93 5.0 into my 95 f150, but I hear the firing order is different. What all would I need to swap? Just the harness and fuel injectors? Any assistance in this swap would be greatly appreciated. I've done lots of engine work, but never a swap like this, so you won't insult my intelligence by stating something you think I may know. I'd like to just print this out and bring it to the garage =)


Any help is appreciated!

Thanks,
Paul

 

I believe you are correct, that the firing order is different. The electronic gizmos between the years aren't really that different, so aside from the firing order issue everything else should graft over effortlessly.

I'd also keep the dizzy - I prefer MSD over the stock motorcraft dizzy anyway.

You should be able to plug the 93 injector harness into the 95 under-hood harness. The wire codes will be different between the years but the pinout I believe is the same.

 

Alrighty. So what exactly do I need to do to make her run right? Just swap the engine harness then? Or still swap the harness and the injectors? If the wire codes are different it'll probabbly be easier if I just use the 95 Injector right?

I'm going to be pulling it tomorrow, and hopefully dropping it in sunday.
Thanks Frederic

 

injectors are the same but the wiring and computer may be different

 

Okay, but If I swap the engine harness and change the plug wires around it should counter the firing order issue, and the computer issue- no?

Never did a swap, so sorry if I am completly wrong...

 

well, the real diference in the 95 is the maf sensor, so it has a mass air flow harness. you can remove just the 95 engine and strip the wiring off it and use your 93 distributor and itll be plug and play with your 93 computer and 93 wiring. the engine mechanically is no different from 93-95 except the cam might be different, but im not positive.

 

The 93 is a speed density EFI the 95 is Mass Air Flow this is a much better system. Change the cam on the 93 to one for a 95 or if the cam from the 95 is still in spec a machine shop can check this for you put it in. Or you can put the 93 in and change the harnesses and computer and have a lot of work and an engine that won't get as good of gas milage and be harder to upgrade if you ever decide to.

 

I would keep the 95 fuel system & mass air . Use the 95 intake & ignition . Upgrade to a good roller cam on the 93 motor this will help the 5.0 alot . You have everthing you need on the 95 motor . Lew

 

First tell us if your '95 is mass air or not. If it is that means it has sequentially fired injectors, and that means you have to either put the '95 cam in the '93 motor(better option) or modify your injector harness for the old firing order. The '93 truck harness is no good to you at all because it would have been a batch fired SD system, so there are only 3 wires in the injector harness instead of 9. And just in case you're wondering there were no vehicles with sequential injectors and the old firing order, so there is no harness you can get that is a direct plug-in.

However if your '95 is SD then you can just swap the motors without changing any wiring except on the plugs which would have to be arranged on the old firing order.

 

I am pretty sure it's a maf engine. I will be heading over there shortly to verify. If it is than I really just need to swap fuel injectors and the cam? I will probabbly do the harness either way, just to be sure. I appreciate it.

 

Just the cam, the injectors are the same on both motors so save yourself the work.


No.. don't touch your harness, you cannot use the '93 harness at all, this is a 100% certainty if you have a mass air truck.. which it should be. Once you put the '95 cam in the '93 motor it will be exactly the same as your original '95, so nothing else will have to change.

 

Okay, thank you
