4.6 to 5.4 swap
I am in the process of buying a 2000 f150 originally a 4.6 swapped now to a 2001 5.4 van engine. They Guy that did the swap just hooked the 5.4 up to the 4.6 harness and CPU. I know right of the bat I'll have to change torque converters he used the 4.6 . After swapping engines he said the 5.4 has no power and can't Go faster than 60 MPH! He didn't have any CPU mods done, so my question is this an easy fix he has no clue what it is he doesn't have internet access so he is clueless and ready to sell to me for $1000 it a 2000 extended cab 4x4 with a fresh transmission! What am I looking at spending on getting it running right? And any clues What's the problem with it?

HI!
I am in process of installing 2005 4.6 2v in older f150 I have the engine,Transmission,Computer, wiring harness, ignition key ,Pats transponder from the doner vehicle but do not have the instrument cluster does this mean I will need a custom tune ?? Thank you in advance for any avaliable info.

97 f150 4.6 to5.4
I glad to findly find someone who says this swap can be done. Everyone I talk to here in Tucson Az say buy another truck that it is too much work to change engines. I have a 97 4.6 with 200+k miles and have got a 02 5.4 with 50k miles on it. The only concern I have is with the intake. The 97 5.4s have the ATV in the intake, the 02 does not. Should I swap the 02 for a 97 intake? Drilling and taping a hole for the extra temp sensor is no problem. The other thing is injectors. Should I use the 5.4 or 4.6 injectors?

The intake manifold tuning valve can be removed from the 4.6 plugged in and bolted to the intake manifold on the 5.4 out of the way. This way it is free to actuate and not set a code. Use the 5.4 injectors as they are newer. My 4.6 had the valve but the 99 5.4 I used did not. I soon had a tune to accommodate the 5.4 so I had it tuned out and unplugged it.
#144
So I have a 99 f150 that had a 4.6 but we swapped to a 98 5.4 from an expedition and originally we tried to use a 98 truck pcm and wiring harness and it ran good but would not shift right or instument oanel work correctly so we switched back to the original 4.6 pcm and harness but it wont start. It turns over but doesn't get fire we've checked the wiring from the coil packs to pcm and cam shaft sensor and crank sensor to pcm they were good any suggestions would be very helpful.
#145
We just completed the 97- 4.6 to 99- 5.4 swap. Starts and shifts fine. However, upon acceleration is bogs down. We eliminated the two rear eco sensors. Would love to hear your suggestions, on getting this van to run.
Thanks in advance.

4.6 to 5.4
Notes for 4.6 to 5.4 swap Part 1 Revised 28 January 2011
Application: These notes cover the F-150 from 1997 to 2004 Heritage model years.
Cylinder Heads: The following info applies to the F-150 and not any other vehicle engine.
4.6 Engine: The 4.6 engine had Non Pi Heads from 1997 to 2000. The Pi heads were introduced to this engine for the 2001 model year.
5.4 Engine: The 5.4 engine had Non Pi Heads from 1997 to 1998. The Pi heads were introduced to this engine for the 1999 model year.
Exhaust: The collectors on the exhaust manifolds are set at different angles and locations. The 4.6 exhaust might not bolt up to 5.4 manifold. You may need to have a muffler shop modify your 4.6 exhaust to match up.
Ignition: All 5.4 engines use Cop ignition. . 2000 and later 4.6 use COP ignition. 1997-99 4.6 engines use coil packs. It is easier to wire your 5.4 using the harness from the 4.6 and use the 4.6 ignition coil packs if applicable. If you use the 4.6 Coil pack ignition you will have to fab a bracket for the driver side coil pack.
Engine harness: To use a 4.6 PCM to run a 5.4 engine: The IAC harness must be relocated to the rear of the throttle body elbow. The oil sender wire on the 4.6 may be too short so measure or test fit the harness to see if it must be extended. All 97-00 and some 2001 4.6 engines use some sort of intake manifold runner control valve. Remove it from the 4.6 and plug it into the 4.6 harness and bolt it to the engine some where out of the way. Note; you can get a tune to remove its function and eliminate it all together.
All 97-98 4.6 engines use an Engine Coolant Temp sensor (ECT) and an Engine Coolant Temp sender. By the 99 Model year the ECT was dropped in both the 4.6 and 5.4 harness as the Cylinder Head Temperature sensor (CHT) was used for the PCM to monitor coolant temps. None of the 00+ 5.4s use ECT sensor or sender. Some of the 99 5.4s still use the sender to feed info to the instrument cluster. You will have to tap the intake manifold crossover pipe to fit the sensor(s) if your 4.6 has them and the 5.4 doesn’t.
Transmissions: the 4.6 and 5.4 have the same bellhousing bolt pattern. That means that all the transmissions will bolt up. All the 5.4 engines have 8 bolt crankshafts. Some 4.6 engines (ROMEO ENGINE) have 6 bolt cranks. You will need the flex plate from the 5.4.
Manual transmissions: If you don’t have an 8 bolt flywheel a flywheel from a 1997-8 4.6 Windsor engine will work. As it has 8 bolts it will bolt right up to the 5.4 crank. Remove the flex plate spacer and install a pilot bearing from a 4.6.
Special note about the different automatic transmissions and their respective harnesses. You cannot run a 4R100 transmission with a PCM that had a 4R70W transmission and vice versa. The transmission harnesses are different and will not plug into the different engine bay harness. The control functions in the PCM are not compatible so the transmission will not function properly.
Torque Converters:
4R70W
ENGINE............Stall Speed............Multiplication
4.2..................1978-2330...............2.3:1
4.6..................2105-2505...............2.3:1
5.4..................1830-2190...............1.9:1
4R100
All Engines......??????....................2.2:1
If you swap a 5.4 into a 4.6 engine bay and use the 4.6 converter you will multiply the 5.4's torque at a higher rate and at a higher stall speed which will put the torque at the transmission input shaft close to the limit if not over the limit of the 4R70W. The 99+ 5.4 produces 350 ft/lbs of torque. 90% of that is available at 2000 rpm. The stall speed of the 4.6 is above the 2000 rpm range so more than 90% is available. 350 ft/lbs x 2.3(4.6 multiplier) x 90% is 724.5 ft/lbs.

i am kinda confused on the thread im back into lifted had 99 had 5.4 triton....
my new one is a 2000 f150 4x4 only bad has 4.6 i want the 5.4 this one has worn cylinder that causes it to smoke some burning oil so i wanna find out exactly what i need to know to swap in 5.4 i have figured i need a 5.4 triton from a 1998-2000 f150 with 5.4 obviously lol i can use same transfer case
now what i need to know is what ill have top do to wiring harness it has coil pack individual ones over spartk plugs....can i use my wiring harness from my 4.6 motor already installed???
can i use my a/c compressor...and stuff ober top of motor ect this is first motor convert will i need new motor mouynts ect please go into detail so i dont screw this up i want 5.4 bad just on a budget so gotta get what i need and no extras lol
do i need different torque converter????
as far as transmission goes ill need flexplate from a 5.4 correct?
im sorry asking stuff already in ur shread but get confussed easily i have adhd so hands on is best for me to learn so could u explain to me a little better
#148
You can use the harness and ECU from the 4.6 truck, just leave it in, but you will have to have the ECU reflashed (tuned) to the 5.4 engine. The 5.4 will have a coil over plug (COP) ignition system, but you can use the coil packs that are in the 4.6 truck if you have them, if you already have COP ignition then you're set. A/C compressor can be reused, but check if the donor engine and the 4.6 have the same number of ribs on them. Motor mounts are the same. I can't help you out with the torque converter question, as mine was a standard, but if you read back through this thread a few times, all of your questions have already been answered through other people asking them. Good luck.

Im confused just got another lifted f150 had a 99 it had 5.4 im looking to swap in a 2000 f150 4x4 lifted with a 6" fabtech lift
it has 4.6 i wanna swap in a 5.4
i understand following
-can use same tranny (do i need a new torque converter?)
-do i need new mounts for engine and i know from what uve said i can use a 5.4 from a 97-99 f150 with 5.4 triton can i go up to a early 2000??? just wanna make sure i get correct motor
-electrical wise can i use the same mine has the individual coil packs that go over the spark plugs.....do i need to do anything to wiring harness to make it work?
- can i use the air intake
-can i use the a/c compressor?
-can i use evrything on top of motor just swap in the motor bassically ???throttle body ect???? tell me all u can please greatly appreciate it
My truck is a 2000 ford f-150 has the 4.6 v8 its 4x4 it was manufactured in 12/99 so im guessing it has non pi-heads can u tell me what pi means ?? this is first motor job ive done ive done everything else i dont take ionformation from book or writting very good ....so i have to ask several questions i wanna make sure i get all i need so i order and get the stuff i need can u tell me exactly what i need make me a list if possible id greatly appreciate it
anyone in the indiana area willing to help me lol be awesome but if not thats okay too i can figure it out and do it
