i have no compression in cylinder #3 so i want to put a 5.4 in my 1999 f150 ext. cab short box 4x4 in stead of another 4.6, just wondering what i will neeed to change or if any thing, like ECU.

 

I just finished mine from my 99 to a 2002 and trans low miles, im pretty happy with the outcome.

Look on ebay, try not to pay over a grand for the motor, as i see TONs of people are way way over pricing their stuff. I got an engine trans alternator power steering all wiring harnesses (didnt do me any good anyway) and all accessories with trans for $1200which was amazing because i talked the guy down, since he was close to me.

 

its easy, just do it. theres more than enough people on here who have done it and can help you with any problem you run into

 

thanks, just wondering if i can buy a 5.4 rebuild from ford and just bolt every thing from my 4.6 to the 5.4, and if the computer will run will work with it fine. also wondering if the injector flow rate is different.

 

Same injectors - 19's

 

will the intake from my 4.6 bolt onto the 5.4, what is ment by getting a tune

 

they are both 19lbs. injectors, but they ARE different. I asked when I got my chip flashed. The injectors are different, the angles and size of the spray pattern. . . .

 

I am using wrong computer to access my notes I will post info later today.

As promised;

Notes for 4.6 to 5.4 swap Revised 5 November 2008

Exhaust: The collectors on the exhaust manifolds are set at different angles and locations. The 4.6 exhaust will not bolt up to 5.4 manifold. You will 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 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: 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 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.

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.

Tuning: It is best to have a custom tune done to accommodate the extra displacement of the 5.4.
You should be able to use the 4.6 MAF as any competent tuner can adjust for it. It is always best to discuss this with your tuner.

Knock Sensor:
The 97-98 99 4.6 uses a 2 wire knock sensor. The 97-98 5.4 has 3 wires of which one is a ground for the shield. Both have a Yellow /red wire to pin 57 on PCM.
1997-98-99-2000-01 Yellow/red to 57 on PCM 4.6 Same for 5.4.
97-98 Pin 91 feeds power for 4.6 and other components. Same for 5.4
1999- 2000-01 Pin 32 for power. Same for 5.4
2002+ Cannot confirm.



Accessories: Some engines have 8 rib serpentine belts and some have 6. Be sure to check so that your accessories have the correct pulley.

Misc: Both engines use the same engine mounts and their location on the block are also the same so your old ones will fit. Unbolt and place aside the AC and PS. You need to remove the intake manifold for the engine to come out. Yes there are 3 bolts on the starter.

Yaa you might as well go ahead and agree with JBrew, same part number, same part. Anywhere you go, rather if its aftermarket or not, they are inerchangeable. Go to jegs or something, copy the part number and compare to the injectors for the 5.4. So if the part numbers are the same, they are the same.

 

I'd be willing to attribute every bit of information along with pictures upon my swap. CANT we make a sticky entitled 4.6-5.4 swap???? I assure you if we do this, attribute all our own info and pics, there will be no further questions on this subject....



LETS MAKE A STICKY!!!!!

 

You were fed Bullsh^it

19's were used from the 3.8 -5.4 models. There are only TWO types of 19's - Standard and updated. The Type 3's were the updated units with IMPROVED spray patterns.

Your PCM controls how long they flow for. I ran Windstar Injectors for quite awhile before updating to the Crown Vic injectors.

Now they may have changed designs in 04, but not on these models (97-03).

 

Damn FRod - That's the nicest IAC hose I've seen!!

 

i went to the ford dealer to get a price for 5.4 rebuild a the price was 3700 canadian, with my discount from the GM sealer that i work at, buth the guy at the parts counter gave me a list of engine codes for different engines but i don't know they mean.
9G-622
9G-876
632 AA
620 AA
894 AA
that is what he gave me, i went on the motorcraft web site and a part number for a 5.4 gas, the part number is SLGB86RM.

 

When I swapped for my 5.4, Troyer told methat 03 5.4s had 24lb'ers. we discussed this because i had the 19lb injectors and he had to be sure to tune for them.

What is the difference between the windstar and crown vic injectors?
