4.6 to 5.4 Conversion

[HawksWR37]

I'm getting ready to swap out my little P*ssy cant take a turbo 4.6 for a 5.4 and i wanted to see what all has to be changed to do this.

[cstreu1026]

I don't think its worth the headache. You turbo kit will have to be modified to fit. Unless you are going to top it with a set of Trick Flow heads (preferably the yet-to-be released R heads) the PI heads aren't going to flow enough to support the added cubes.

[HawksWR37]

Well ive already got the 5.4 coming on tuesday lol. the turbo isnt my biggest worry right now because im already pegged on hp by my transmission. I'm more worried about strength than anything.

[cstreu1026]

Well the 5.4 won't be any stronger either unless its out of a lightning.

[HawksWR37]

well everyone i talked to said the 5.4s were built stronger because there made for towing.

[Dirtyd0g]

5.4's are not good performance engines unless they are supercharged. They tow better but don't expect it to be faster. You are just relocating the power into a different rpm range for minimal gain.

[cstreu1026]

well everyone i talked to said the 5.4s were built stronger because there made for towing.

The non-supercharged 2V 5.4 have cast cranks, powdered metal rods, and cast pistons just like 4.6's. They tow better because they make more torque. Even with a turbo, if its has stock PI head I would be surprised if you it made power beyond 5000 RPM.

Well im reading the specs and differences and the 5.4 have larger rods which can withstand more force. (this is what im looking for since ive went through 2 4.6s because the rods). and i was gonna swap my heads from my 4.6

[Dirtyd0g]

Larger rods for a greater force. The piston size is the same making a 5.4 merely a stroked version. The long stroke limits rpm and puts much more force on the rods. A 4.6 handles the abuse better and good parts can be had for less. 03/04 cobra rods will handle most 4.6's

Damn, you've been through two 4.6's now?

[HawksWR37]

yeah the first one SHATTERED a connecting rod and the second one spun a rod so im looking at different options.

[gbrown8439]

Listen to what these guys are nicely trying to tell you, they're right. The 5.4 internals aren't much if any stronger than the 4.6. You are going to go through a lot of trouble swapping engines just to have a motor that isn't any better than the one you had.
Also, the heads on your 4.6 are identical to what comes on the 5.4 so swapping them is a waste of time.

How much power are you trying to make?

[97dustang]

where did you get your 5.4 from?

[cstreu1026]

The only way I think the 5.4 is worth it is if you are building an all out 4V with lots of custom parts.

[HawksWR37]

well in december im going to put all forged internals in and swap to 4v heads

[Waffles]

Well im reading the specs and differences and the 5.4 have larger rods which can withstand more force. (this is what im looking for since ive went through 2 4.6s because the rods). and i was gonna swap my heads from my 4.6


well in december im going to put all forged internals in and swap to 4v heads

You've got 4v heads on your 4.6? Or you're changing your mind? Or you're changing the heads twice?

Give Cincy Speed or Dayton Performance a call. Talk with someone about your goals. Get a plan together with them before you go buying stuff.

[HawksWR37]

Well as of right now i had a choice between a 4.6 with 120k miles or a 5.4 with 80k miles. After i talked to my mechanic at work and various other people i decided to go with the 5.4 because i went through 2 4.6s. I'm not so much looking for power right as much as im looking for durability. In december i will have money again to do another project where i plan on putting 4v heads onto the 5.4 and various upgrades such as cams and forged internals. I am dry of funds right now and just need a durable motor. the 4.6s have been pissing me off so im going a different route this time.

[97dustang]

i have a 4.6 with 8k miles i'll trade you for that 5.4 lol

[HawksWR37]

i have a 4.6 with 8k miles i'll trade you for that 5.4 lol

lol whys that?

[HawksWR37]

i have a 4.6 with 8k miles i'll trade you for that 5.4 lol

If it was a 4v i would lol

[red srides]

if u take a 5.4 over 6000rpm it will come apart but the 5.4 has a steel crank take the 5.4 crank and put in the 4.6 and have your car tuned to safe tune and u have no more problems

[HawksWR37]

if u take a 5.4 over 6000rpm it will come apart but the 5.4 has a steel crank take the 5.4 crank and put in the 4.6 and have your car tuned to safe tune and u have no more problems

well i dont have a spare 4.6 layin around lol

[cstreu1026]

You can't put a 5.4 crank in a 4.6 at least not without custom rods and/or pistons. A forged steel crank won't do a damn thing for spinning a bearing or destroying a factory powdered metal rod. Infact the stock cast crank is lighter than a forged crank and can take just about anything you throw at it. There are plenty of people who sping them well past 7000 RPM and I have yet to see one break.

[Dirtyd0g]

Personally I see the best results for the money using the teksid block and crank. I'm not a big fan of the heavy forged cranks.

Well right now im not looking for power gains what so ever. I'm happy at 380 horse untill december. December i will have money to invest in stuff but untill then im gonna try a 5.4. it cant be worse than my 4.6s.

[cstreu1026]

You do realize that you are going to have to hack that turbo kit pieces to make it work on a 5.4 2V and then start all over again to make it work on a 4V? Seems like an awful lot of work. I would guess that almost all of the plumbing will have to be re-worked to work on the 5.4 with its increased deck height.

Well i am getting the intake that is made for the mustangs with 5.4s.

[HawksWR37]

And honestly im not as worried about the turbo as much as i just want to drive my damn car. in the past 5 months ive got to drive it for 4 days.

[cstreu1026]

Well i am getting the intake that is made for the mustangs with 5.4s.

It's more than just the intake. Because the increased deck height none of the plumbing will line up correctly. The heads will be further apart so the cross-over for the exhaust will need to be cut apart, lengthened, and welded back together. In turn the down pipe might have to be modified too. The intake will sit higher so the same sort of thing will have to happen to the cold side plumbing. The intake for a 2V will be different for the 4V so you will buying adapters or a HPS intake for $700. For the 4V with Lincoln Navigator heads you will need an intake from Sullivan which runs about $1K with their plenum. At that point you will be more or less starting from scratch with the turbo kit since nothing will be even remotely in the same location.

If the 5.4 has been sitting for a while you could end up with another spun bearing just like the 4.6 and you would be out a lot of time, money, and effort.

Do what you want, but I'm just trying to save you money and time in the long run.

All im saying is that i dont have money right now to do expensive stuff. The turbo is the last priority as of now. What ive been saying all along this whole thread is that im going to have money in december to do more extensive stuff but right now i need a running motor. I'd rather take my chances on a 5.4 that has half the miles then the 4.6 for the same price. I understand what all of you guys are saying but im not building a race car. I like custom stuff, I like doing car shows more than anything. If i have to run N/A untill december i will. but i gotta have a strong running motor.

[cstreu1026]

If you don't have the money to do expensive stuff then why are you going to put a 5.4 in it? Putting a 5.4 is going to cost more money. A 5.4 is exactly the same thing as a 4.6 just with a taller deck and a longer stroke. The only advantage would be that the longer stroke will produce more torque. They have the same cast pistons and powdered metal rods. You are gaining zero strength and lowering the power band. You are buying a special intake just to make it work so the 5.4 which is going to cost you more money. Even running NA will cost you more. There are no off the shelf exhaust components designed to work with a 2 valve 5.4 in a mustang. At the very least you would have to have a H or X pipe fabricated to work.

or he could just trade off that 5.4 for a 4.6 with 8k miles lol its still running in my car if you want you can come check it out, then run a 4.6 n/a until december then build a 4.6 built to take the turbo abuse :)

does it have pi heads? 2v 0r 4v?

[NXcoupe]

The only reason you spun a bearing in that engine is because it came out of a wrecked car. A tune is not going to spin a bearing and neither is a powdered metal rod. It was sitting for a while, or impacted when the vehicle hit an unmovable object and the bearing got damaged. Just take it back to them, trade it for one that you can hear run and is in good shape and be done with it. Your tune will work great with the stock 4.6 and that hp is nothing to sneeze at since it made it from about 3k all the way up, but is an insanely safe tune, so there is even room for more power if you want. We just decided before we started, I thought, that we would keep the power down so it was safe and so your junkyard engine wouldn't fly apart. the tune you have is safe and still gives you good drivability and quick power and torque. Just wish you had a good engine for it that would last.
If you want, I can come up with a nice, low milage engine for you that you can put your turbo kit on, and have some fun with this summer. I'll even throw it back on the dyno for you for free, no matter which way you decide to go engine wise. I just want to see your car back on the road with a turbo on it, and having fun with it. That's what this hobby is all about.
Whatever you need, just let me know and I'll do my best to help you out as always. It was nice to finally meet you the other day.

well the rods are longer, but I do not believe they are larger? I would have to look the specs up, can't remember off the top of my head.

Thanks mike, I had called them and they gave me my money back and knocked 500 off of a 5.4 they had. thats why i am doing this conversion. I'm gonna call chad from On3performance and see if we can get some header pipes made for the 5.4 to run my turbo. I didnt think it was your tune that caused the bearing to spin i figured it was because the motor had sat there. I know that essentially the 5.4 is a stroked 4.6 and can handle the same power but i had planned on stroking my 4.6 is the first place. This motor is basically costing me 300 and has less miles than the 4.6s they had there. I'm just going a different route than the 4.6s. and did you say either way you'd tune it for free? :) lol

[pegasus]

my little P*ssy cant take a turbo .

you'd be back into a turbo sleeper before you know it, and no one has mentioned it won't fit under a stock hood without lowering the kmember. Just seems like a door that opened to answer your problem. low milage 4.6 bolt your turbo on and go. But hear it run and beat the piss out of it before you buy it, lol, just to make sure.

Well i was going to get the intake adapter plates that make my stock intake fit under the hood. It was the only quick option i had. that why i went ahead and moved on it.

[02mingryGT]

You can't put a 5.4 crank in a 4.6 at least not without custom rods and/or pistons. A forged steel crank won't do a damn thing for spinning a bearing or destroying a factory powdered metal rod. Infact the stock cast crank is lighter than a forged crank and can take just about anything you throw at it. There are plenty of people who sping them well past 7000 RPM and I have yet to see one break.
+2 on this. I kept my stock crank when I rebuilt my 4.6. I laugh when I see people list forged crank in their mods. 900 dollars down the drain.

[HawksWR37]

I sent a pm. please get back to me asap.

[HawksWR37]

So i was reading on multiple sites that 4.6 shorty headers bolt up and fit right on 5.4s? can anyone verify this?

[NXcoupe]

Kind of doubt that. But who knows? Only way to verify it is to try it. Then you get the engine in and the headers don't work, then what? But then that's the only way to see if they will work. I highly doubt it, as 302 and 351 headers are different, the block is taller on both the 351 and the 5.4, so it raises the head up farther out of the engine bay, and closer to the shock towers.

[cstreu1026]

The heads are the same so the headers will bolt on to the heads but a mid pipe for a 4.6 won't match up to them since they will have been moved further apart. The mid pipe will either have to be custom made or one for a 4.6 will have to be modified to fit.

I was reading online about this swap yesterday and the adapter plates seem like a real bad idea. They move the injector up and away from the desired location and the result is that you have to add a significant amount of fuel to the tune to compensate. Another thought that crossed my mind is that they woudl also be adding runner length to an intake that already has very long runners which will lower the power band even further.

Thats an awful lot of work in a 2 valve GT just to get 300 HP. In a fox though any mod motor is going to be a lot of work.

Nice car man. So ive determined that i need a new flywheel and clutch because mine is a 6 bolt not 8 and the intake adapters. then my buddy is got do some work on the turbo downpipes then that should be it? correct me if im wrong?

[NXcoupe]

I have an 8 bolt crank that might just work with your clutch over at the shop. Bring yours to match up, but I think it is what you need.

[HawksWR37]

Aje is dropped. Only problem I'm having that I'm yet to address in the hydo boost I got from you, there iisnt any room for it. And I'm not doing manual brakes

[cstreu1026]

I didn't say you have a 2 valve. I said that's an awful lot of work to swap a DOHC 5.4 in to a 2 valve equipped GT just to make 300 HP at the crank.

hope to make 400 plus na then to twin 67.

[HawksWR37]

like an 8 bolt flywheel?

Huh, so what are you gonna do? Move it out some? I've seen guys do that on the web for clearance. So dropping the engine makes it wider at the m/c point?

[orangeconv]

There is enough room to remove some of the strut tower and weld it back in so @ this point I will probably do that, the 4.6 fits without issues, the 5.4 is about a half to an inch wider right on the top of the vavle cover

[orangeconv]

I have a few extra if you need one.

Here is a link for you, guy just did a 5.4 swap. He encountered issues and overcame them, etc. Good reading. The shortie headers will work, but the hpipe had to be custom done/modified to work.

Thanks mike, so the only problem i saw that he had was the midpipe no matching up. My turbo down pipe will probably have to be extended about half an inch.

[NXcoupe]

Yep, that and your downpipe depending on where it runs will have to be modified as well because the turbo will be higher making the pipe move up as well. Might cause an issue, but might not too. Start posting up pics and show us the progress man. You need to swing out to the shop and check out that coupe I just got too, it won't be there long tho, lol.

So what is the best bang for my buck clutch wise?

Centerforce dual friction or spec stage 2. both work really well but you are going to have a lot of torque with the turbo and that long stroke, might have to end up going with something a little tougher.

I was looking at the centerforce one. But if Im upgrading it which one should I go with to last the long haul?
