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.

 

I've got a set of FRPP headers that are cracked on my '95 Crown Vic. I beleive FRPP had problems with the earlier made headers by not having enough weld in the tube to the flange. I've heard alot of mones and grones on the Crown Vic forums about it.
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.

 

got the passenger header done today. still needs to be finish welded some. but at least i have one done.

 

also had some help while under the stang.....

 

somebody jump on this deal.

$500 lightning long block

 

good deal there

 

Still has 2 days, wait till the end of auction and see what the price is. $$$$$$

 

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.

 

Absolute.....junk!

Why did they do the forged pistons but not the rods?

 

They have to put a weak link in the system somewhere to keep everyone from building 600 horsepower monsters and blowing things up then crying warranty to get a new one.

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.

 

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.

 

YEA!!!!!!!


hopefully i can get started on the driver side header this weekend.

 

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......

 

I can't wait to see numbers from r3d & myillwill's setups to compare with mine.

 

i just want to see mine drive.....

 

Just curious? What year block are you using?
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.

 

What you are referring to is called the NVH block, but as far as I know the non NVH blocks are just as strong.

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.

 

The material added wasn't really for strength but more so to reduce NVH by a percent or so, just so people hear their engine that much less.

 

MMR has confirmed 3v 5.4L Intake Adapters

They said ETA is about 3-4 weeks out and cost roughly $350

 

It is a 97 block.

 

give me a link to the MMR adapters

 

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

$710 with 5 hours to go! Anyone?

 

I'm looking at picking up a vortech kit from a buddy of mine for a sweet price. If I can make it work do you guys think 8psi would be fairly safe on the stock bottom end or should I look at getting a larger pulley?

 

The problem with the stock shortblock is you have a few variables to watch for.


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.

 

It's a vortech s-trim, no power pipe and no inter/aftercooler. My n/a numbers are 290hp/340tq to the ground.
