You don't NEED a HPS Intake. you can Run the Stock mustang intake with Adapter Plates.There only $200.

And i dont see why you need a widend h-pipe unless its stock..My 4.6 Pro Chamber worked just fine?But then again a H pipe and Pro chamber are a tad different but most h pipes slide in and out at the H so you should have enuff adjustability.

Do you even have a 5.4 yet?

I don't like to get in to it about 2v and 4v but this guy don't got alot of $$$$ A 4v for $3000 come on YES AND NO A stock 4v lost to the B/mustang, in the 5.0 Magazine, If he want a 4v go on and do it , but a GT with mod can spank that a$$ all day long and a lightning GT can spank a N/A 5.4 4v and a 96-98 4v heads flow 231cfm 99-01 225cfm 03 233cfm the new Trick Flow 240cfm that the FACTS, now you can get the 4v to 350cfm for $1500 !

how many 5.4 have you purchased to obtain this wealth of information? you can get a running navi motor with less than 50k on it for 1,500$ easy. and its not all about cfm, my man. sure the "flow" numbers on the tfs heads are impressive, but look at the numbers. you will NEVER find a 2V head capable of the performance a 4V head can do. NEVER EVER.

its in the tune, not the computer...

similar parts list as the 2v swap. they are really the same stuff, just 4v compatible. differences being the intake and a larger motor.

get the sullivan intake
look into k member spacers

look at this 2v and a 4v 5.4

Both the 5.4 and the 4.6's up till 05 use the eec-v and will work. As for using the GT tune on the 5.4, it will work, just stay out of the high RPM's. His GT ECU will be the perferd ECU because it's already calibrated with his PATS key.

i was thinking the h-pipe needed to be altered for some reason, maybe something i read in a different forum

no i want to get everything figured out before i spend money. plus i dont have any to spend right now . and i want my current engine to last a while longer until i have the money.

im really not interested in some kids streetfire video of cars driving down a highway. that video is meaningless. what i am talking about is part vs. part. 2v head vs 4v head on the same short block. the 4v head will alway outperform the 2v head. every single time. there isnt a portjob in the world that will get you the same performance on a 2v head that you will get from a stock 4v head. ive seen it. the tfs heads have impressive cfm flow numbers, but they still wont perform as well as a 4v head. im not sure what you are getting at, but i hope your not trying to argue otherwise...

because the 5.4 deck height is taller it causes the exhaust manifolds to bolt up farther apart than they would on a 4.6. think of a ice cream cone as a representation of the motor(or any downward pointing triangle for that matter). on a 4.6 the headers would bolt up at an equal height up the ice cream cone. on a 5.4 since the port are higher up the headers would bolt up at equal point higher up that same cone. the space between those 2 points on the cone is greater than the space between the two original 4.6 points. because of the added distance between the headers there is a greater distance between the collectors which is where a mid pipe would bolt up. the problem here is that your 4.6 midpipe can accomadate the greater distance between primaries and thus will not bolt up. the solution is the add the appropriately sized piece of pipe to bridge the gap, if you will, between the two collectors for your headers. i havent heard of any midpipe working out without modification, but if such a thing does exist as 330cube has stated i would look into that, because it might be an easier way to go. personally, im going to have an exhaust shop fab up a custom mid pipe for me.

so basically i will need to modify my o/r h-pipe lol

ya, most likely. just get the header on and drive it to an exhaust shop with open headers. give them the pipe and some cash and say, "figure it out" lol. its nothing major just a small addition of an inch or so.

You are right 4v heads flow more air, but a 2v 4.6 can beat it

No but it look like that one. I am on the lightning forum. That why I know 2v can do what a 4v can do! I make 503 to the wheels and 560 tq . They got lightning now hit 700 to 800 at the wheels ! All I am saying is 2v heads can and is making the same power with out the flow. Now yes 4v can make 700 to 1500 for lot more $$$ I would like to see how much it would cost to get a GT and put a 4v in by a shop that can make 700rwhp and don't break . My whpple $3100, heads $2600 that cams and springs too 5.4 block 3700, OK let see that 9400 wow I know a guy got 13000 in TT kit 4v and it not done. This is why I went with 2v. I don't have 4v money.

and so can a honda civic with the right mods... whats your point? however, if you put the same mods on the two different cars, one 2V and one 4V, then who do you think is going to win? how about the same mods on two cars again, one 2V with the best port job ever achieved by a human and one 4V w/o a port job. the same guy is still going to win. care to guess which one?...

why are you claiming that a 2v can do what a 4v can do?! and why are you citing some no name guy who likes to spend lots of money as ur reasoning for think 4Vs are more expensive? as previously stated: you can buy a complete running 5.4 4V navi motor for $1,500 or less with 50k miles or less. that 1,500$ motor will stomp any 4.6 2v given they have the same mods. it will stomp any 4.6 4V given that they have the same mods. 2,500$ spent on the 5.4 4V and the sullivan intake is $2500 well spent.

Please show me where you can find a NAVI motor for under $1500 dollars. I cant find that anywhere. They are all above 2k.

let me try to get the link. its a sick page that searches the inventories off all salvage yards in your area. lists all info like price, miles, year, model, comments, etc. i lost it, but ill find it for u.
