F150 5.4 4v with supercharger.

[darkwaterdevil]

i can get a 5.4 4v from a 99 expedition for only 125$. i was wondering if any superchargers will work with this. like mabey the lightning super or something else

 

[darkwaterdevil]

Anyone?

That motor is a 2v motor. And you can swap a lighting or Harley supercharger on there, although I don't know how long it will live. I've heard the internals are different.

 

[darkwaterdevil]

Its not a 2v its a 4v. I looked at it

Then it's not an Expedition, it's a Navigator. There's no bolt on option out there for you. Kenne Bell made a Navigator kit years ago, but I doubt you'll be able to find one. Any supercharger setup would require large amounts of custom fabrication.

shouldnt be too hard to get a vortech or procharger to bolt up.

 

[darkwaterdevil]

They probable took the engine out of the nav for the exp. Is it a good engine? Easier to do a turbo?

 

[SID297]

What are your goals? It's a fine engine, but bolt-on mods are basically non-existent for it.

 

[darkwaterdevil]

Towing, and performance. Have a 4.6 now

Yeah it has to be a navigator then. I have driven both 4.6 and 5.4 trucks. The 4.6 seems a little more torquey off the line but the 5.4 is clear a strong and more hp motor. I held on pretty good with a bullitt today. I would jump on it. I hated my 97 4.6 truck. I'd take a 4.2 over another 4.6 97-03 anyday.

Just find a V10 and install it. It would take some fabrication but nothing as bad as a one off blower install.

 

[darkwaterdevil]

There are superchargers for the 5.4 4v stangs will that work?

 

[SID297]

Not without a lot of custom fab work. The heads are different enough to give you problems, then you have to figure out firewall clearance and a front drive solution.

 

[darkwaterdevil]

I read they are the same heads and engine

 

[SID297]

You are reading misinformation. They are different designs.

 

[darkwaterdevil]

I think I'm just going to do the 5.4 4v by itself. Can I use the 4.6 computer and harness?

 

[SID297]

No. The 4.6 has a VVI and the 5.4 does not. The harness is very different too.

 

[Ironhand]

I can put a supercharger on a 5.4 4 valve. I've already done one. Im in the process of doing a second one now.

the first year there was any vvi or any thing on a modular was with the 3V stuff if he has a 4.6 the swap can be done with few problems. a buddy had a 4.6 f150 and i found a motor at a junk yard that said 99 expedition motor but it was a 4v and it was only 700 dollars. my friend when and picked it up, upon pulling the spark plugs, oil pan and other parts the motor was found to have never been turned on. i have not idea how the junk yard had it but the vin on the id tag was 5.4 2v expo motor and it was clearly not that.
