Motor is shot, 5.4 dohc swap?

Found out today that my motor has a rod knock....was looking for motors and found this

http://lexington.craigslist.org/pts/4093660535.html

What else would be needed to run this? It's right around the same price as some 4.6's I found

Maybe different k member ? Or just mounts

And a tune

I believe it will bolt right up to everything I'm not 100%.
Where are you from? I'm about 20 minutes from Lexington myself.

Isn't the 4.6 and 5.4 the same block? It should colt into existing mounts and k member. I think hood clearance is a major issue.

This swap is has been fairly popular, and there are plenty of write ups out there. Its not the exact same block as a 4.6, the deck is a little taller. And you might have to bend the exhaust or custome fab it to fit better. It is a 4v, and that's the only 5.4 engine that's N/A I would consider. But it should bolt right up to your K member and mounts. There room will be tight in the engine bay.

Your tranny will bolt up, but it is an 8 bolt crank. So if you have a romeo 4.6 you would need a new flywheel since they were all 6 bolt cranks. But if you have a Windsor, your fine on that subject. For that price, as long as the engine is good, I would probably buy it myself!

Before you commit, do your research. Its possible, but its not a simple swap. And depends on how much money you want to spend. Oh also, you will need a big cowl hood too...

There is no good intake for the DOHC 5.4L motor. Well there is the Aussie intake but that needs a lot of modifications. For the money you'll spend, its totally not worth it. Also, can't get the link at work but if its a Navigator engine, those heads are not the greatest in the world either. I'd build a 4.6L 2V or 4V or even a 5.4L 2V before I did the 5.4L 4V motor. If you want displacement do a 5.1L stroker and throw 20 psi at it.

The only way I would ever put a 2V 5.4 in a Mustang would be if I'm going F.I. with it. Otherwise, its a complete waste. The 4V version when compared is much better, and for the price of the longblock and extras (600) its not that bad a deal, but like you said there is a lot that would go into it. You could feasibly do the swap yourself, and piece together the extras, for around 2-2.5K with the engine the OP posted. (Which I should add is in the ballpark of a remanufactured 4.6)

Obviously the easiest route would be to swap in another 4.6, but I think the whole point of the thread was the fact the OP found this engine for sale at a reasonable price, and its readily accessible. Plus once completed, that 4V 5.4 will have numbers comparable to a supercharged 4.6 2V. But then again you have to factor in how long it would take you to source the parts you'd need for the 5.4.......

$2-$2.5k would just be for parts and machine work for the engine to make it worth even getting a 5.4L. Not to mention the driveline, fuel system, suspension, electronics and tuning. People always think they're going to save money finding a "deal" like this. There is a reason the guy who had this motor never got around to swapping it into his car and that reason is he started running numbers on it and realized he was getting himself into a $10k project at least to get it in RIGHT and its not worth it.

And the 5.4L 2V is not a complete waste at all. Actually if you don't mind a little extra weight and 5.0 pushrod like off idle torque its a great option to drop in a stock one as a stock replacement for a 4.6L. It literally is a 99% direct bolt in. They make around the same horsepower as the 4.6L but around 330wtq with all the "bolt ons".

You're such a Debby downer man! Lol I'm gonna have to disagree with you again. Sure you could spend 10K on ANY build; with porting the heads, cams (especially 4V's) , etc...etc.. but the point is you put a basically stock 4V 5.4 with either the Boss intake or a used Sullivan intake (set you back maybe another 600 bucks), and make as much power as a 2V 4.6 with a blower. Heck you could use the Navi intake if you really wanted to and still come out on top. Check out this thread to see where I'm coming from:

http://mustangforums.com/forum/4-6l-...swap-faqs.html

Some subframes and LCA's and your suspension is done. I would never say not to upgrade the fuel system, but You don't need a ton of stuff for what this build would produce. You'd be nowhere near your price tag of 10K; And again if your building this engine to produce gobbs of power, then yeah you COULD spend alot of dough. But the point is, you don't HAVE to, to get an engine that is much better than a 2V 4.6, and for about the same price as replacing the stock motor.


Granted theres a minimal weight difference between a 4.6 and 2V 5.4; but a Stock N/A 2V 5.4 swapped stang will run slower than a stock 2v 4.6 would. Sure theres more torque, but without a way to put it to the ground efficiently its useless. Why awould I spend the money on the swap unless I'm upgrading (i.e. supercharge or turbo). Drop a Lightning engine in and I'm all for it. But to put a N/A 2V 5.4 in serves no purpose in that context. Its just gonna be a dissapointment to whomever did it (unless they like to do lots and lots of burnouts). Plus in the long run, you're gonna get more gains out of the 4V then you could the 2V, and I think we both can agree on that. There's a reason why Ford used the 4V 5.4 in the 2000 Cobra R, GT500, GT, etc...etc...

Regardless, the OP has the opportunity to purchase this 4V. I think if he does his research, its a very realistic project and can be done for about the same funds as putting in a remain 4.6. Like I said before, if that was for sale near me, I would shelve my Lightning swap plans, and totally buy it for that price as long as it checked out. I've already got the hood!

To each their own. The only 4V 5.4L I'd ever do would be a 2000R build. IIRC there are still a few sets of bare OEM R heads on the Evilbays for $2k but good luck ever finding a real R intake lol.

Yeah, exactly. It would be awesome to do a 2000 R build. And you'd probably have better luck finding Jimmy Hoffa at this point than a real intake!

Sorry guys, I apparently wasn't subscribed to my own thread. I have a few options here. I found that motor, a used 4.6 2v with 90k that comes with Bbk cai, Bbk 78mm, Bbk udp, and heedman LTH for 700. Also found a 4.6 2v for 575 with a guarantee...forgot mileage on that one. I have a procharger for a 2v already. 10-12lb pulley 3core inter cooler.

02-05 exploders have a basic PI engine and a WAP aluminum block so yes you heard correct. Best stock 2v to replace hour blown up motor with.

Its a modular block with PI heads, PI cams etc... you just swap anything you need over from your tired original motor and drop it in.

I just put a vortech v2 on my car and I'm going to run the snot out of it so I'm thinking I need to find a explorer motor and put forged internals in it and then I'll have a heck of a motor and it be lighter too

No it's a WAP block. Made in Windsor. Teksid is made in Italy?

The Exploder PI motor is a WAP aluminum block. Teksid WAS made in italy from 93-98 for Ford. Teksid is the same company that makes blocks for Ferrari btw. Either block will support big power, more than 99% of ppl will make but the Teksid IS stronger. I have a Teksid and 98 forged Cobra crank sitting in my garage currently and I plan to build it up when funds aren't so... tied up.

Then you need a fully forged rotating assy and the supporting cast to match.

Supporting cast as in fuel system, driveline, suspension, bolt ons, wheels/tires, chassis stiffening etc...


ALSO, back to a post I made in the middle of this thread about the 2000R stuff. There are a few pre-production 2000R intakes on the evilbays right now for $2k a pop. A guy on the Corral also claims to have 4 real ones FS. There are ALSO two bare sets of 2000R heads left on ebay out of the 5 originals that have been up for about a year. $4k gets you the best modular heads and intake to ever be produced and looking at serious, SERIOUS power ability.
