Anyone intrested in 5.4L swaps, in here. Need you to opine.

Glad I found you guys. I have been lurking other mustang forums, and have yet to find anyone talking about swapping other engines in. I am currently driving a swapped honda. I really enjoy the process of starting with a basic car and building what I want out of it. My first question would be; Is there any reason when buying a 2005+ mustang that I would need to get the GT if I plan to start from scratch in the drive train? Would a V6 manual trany car work for this purpose? and My second question is; Is any one doing a 5.4 swap in a 2005+ mustang. I guess I want to relive my youth and the new stang is calling my name.

In the pic below you can see the white lines showing the general location of the inside walls of the #4 pipe. The Green shows the #6 tube walls. Notice that they fuggin near intersect at the outboard side of the #4 pipe. I used a dremel and a coarse burr to cut the interfering bit out of the #6 pipe and viola.
I'll try to get some pics of my actual headers so you can see the cuts from the inside.

The FRPP set I bought for my 5.4l Mustang build had ALOT of weld in the tubes. They must have realized the problem and fixed it with more weld.
Not sure what port it was, but it had the biggest booger of weld and would have cause some HP issues. Not to mention all of the tubes at the flange has alot of extra weld. My fix was some major porting! I did a little something to all the ports, being carefull not to take to much out.
I would have to say with the extra weld around the ports it was about a 3/8" restriction in O.D.

these headers had cracked but myillwill had them properly welded up. It looks like the rear driver side tube will always be subject to stress cracking. JBA's have a better design to keep that from happening but the problem is native to most all headers.
Friz.. start with what you like. The hard part will be the wiring. If you plan on a full swap properly done on a v6 car then you'll have to replace the ECU, wiring harnesses (x3), fuel system, rear axle, drive shaft, transmission, engine, and a bunch of little things. So, no not really but it's WORLDS easier to start with a V8 car.
There are several people driving around 5.4L 05+ cars but most of them are 4v headed motors set up for drag racing. A 3v version would benefit from at least a stage 2 port job and some nice aggressive cams.

Thanks redneck, I probably have a lot research to do. I want something modern but reminiscent of the late 60's big block cars. I think the 05+ could fit the bill nicely. I wish there was a modern big block to drop in.

up to about 1500 is pretty reasonable. Even if it needs bearings and a shine on the crank. That's a respectable motor. I'd have to replace the rods though... they're the same as in all the other 5.4's... not the best.
#2832
As a side note, there is a rumor floating around the link I posted on MF that MMR is working on 3v adapter plates because the RR plates are still a LOOONNGG way out.
#2833
Ford only planned on them making around 400hp. There was no need to put hard core h-beams in it just to have guys do exactly what 2eighty1 said. I know for sure there'd be a lot more 9 second lightnings prowling the streets if they did.

Looks like the motor goes in this weekend. I just slapped down a deposit on the labor and made arrangements for the motor to get to the shop that's doing the work. Cost me a pretty penny but it's finally happening.
#2836
Motor is in the shop. I had to buy a BHJ honing plate because nobody around here had one. I worked out a deal with the machine shop to lease it back to them when they need it. So if anyone is doing a 5.4 or 4.6 build in Omaha, Ne area let me know. Anyways, block is all hot tanked, and is being bored this week, crank is getting performance grind before everything is being sent to balance shop. Block has been measured up and will need to be decked .020 to get pistons where we want them.
It will be right at 8.5:1 with gaskets and 49cc head. We calculated it with a .020 over bore and also came up with 334 cu/in. Im getting excited....took my T63 apart today and made sure no piston material from the 4.6 made it through it. All was good, just had about a quart of oil in the hot pipes before and after the turbo. Cant wait......

In 2003 Ford added 18# of more material to the 5.4l block to aid in cylinder bore strength. The blocks before 2003 had issues with the cylinder walls not having the same amount of material all the way around.
Just thought I would add my 2 pennies.
That's gonna be one mean ride!

I wanna drive mine too!
Fundings are holding me back now.
I still need to get a water pump and some AN fittings for the intercooler. Weld some places on the intake so the injector rails hold down. Get a 1999-up "skinny" alternator", mines to fat. Make an underdrive 10 rib crankdrive pully about 7" O.D., Holly don't have any more and they will not release the prints on their design.
Get a fender cold air intake, boost gauge, oil pressure gauge(stupid factory on/off switch juck gauge) Big MAF meter and get a tune. I got the 255lph fuel pump to get in, but I have to much work to do right now. More work more money. Hopefully I can get some gears turning in a couple of months. I'll be sure to post pics along the way.

Just curious? What year block are you using?

The added material was not for strength, and if your lucky (like me) you can pick up a pre-NVH block WITH forged crank for a good deal. NVH blocks dont have forged cranks.
Besides that, thats 18 pounds MORE weight I have to get from 0-100 in a hurry, haha.

Nothing online yet but I emailed them yesterday - this is what they said.

Anything over ~12 PSI
anything over ~450 RWHP
So 8 PSI and 470 RWHP is trouble, 14 PSI and 300 RWHP is trouble, but 8 PSI and 380 RWHP is great.
Do you know what your n/a #'s are ? Also is it going to be intercooled or not ? S trim, T trim ? Powerpipe or stock ?
We can probably figuire out about what your numbers will be and work from there.
