i have 2 5.4 2 valve covers and 1 navi cover,if it will be of any help let me know

 

yes, please lay them out on butcher paper and make outlines and indicate where pulley bosses and stuff are. The more we can get the better the bracket will be.

 

tj has been super slammed lately, he has bought a bigger building to move to. progress on the front mount long tube turbo headers are coming along.

if your looking for a really nice nitrous kit, i have a direct port nib i'll sell you cheaper ten you can find elsewhere # 08100NOS

 

I responded at the corral... it's 50/50. If you can get the 3800 bucks out of your 4v parts for a set of heads/cams/intake then your only question is do you really need the extra power from a 4v or do you just have the I-want-it-now's and you need to be patient?

I personally like sticking with 2v's in 2v cars and 4v's in 4v cars. It's just easier.

it would seem FTP only has an online presence to say that they would rather you call. In any case, slap a TVS on it at 15psi with the TFS heads and see if it doesn't scare the living hell out of you. If not, big up the pulley to 18psi and hook up a methanol kit or a 75hp wet shot of nitrous to do some extra charge cooling.

The best part about a blower is it won't make boost until you get your foot in it a little bit. You'll be able to take off from stop lights and deal with traffic jams and stuff just like always. 3.73 gears actually help a bit there. It's the launches on the street that they make life interesting on.

 

I want your navi cover.

 

just out of curiousity, how much do you want for that direct port kit?

 

for someone here i'd do 1k shipped. it was close to 1400 once it was shipped, but it has to go since i have too many parts in the shop.

 

Been AWOL for a while guys sorry.

Minor update on my car: found a guy with a vortech V-2 on his 5.4...he just used the early (96-97ish) timing cover off of the 5.4 and the 96-99 vortech kit bolted right up. Go figure.

At any rate I bought the kit from him, and were swapping timing covers, injector, and some other small parts and hes throwing in the FMIC and power pipe so he can sell his car N/A....on 6PSI stock 5.4 engine with the vortech he was making 390/400. Im excited to see what mine will throw down, I know the cams will probably kill me but Ill deal with that when i switch to TFS heads.

 

pics of the install......

 

As soon as I start on it I shall

 

I always figured one of those kits would work. I wonder if they make a kit for the navi that I could use with a little modification.

 

Been a while since I've been on. Got the 5.4 finished and broke in. Its at the dyno right now and just put down 343 hp/365 tq to the rears. Have yet to add some timing and having a transittion problem at 2500 rpms. End all be all I'm looking for 350/380...next week we'll see.

 

redneck, just got back on here, i've been busy at work.. my car is sitting without a engine in it now, im still looking for one, believe it or not, where im from(Houston Tx), they are not the easy to come by.. im hoping to get the intake now, i've had some time to save up some cash, if i can find a 5.4 2v motor that runs for under $700 i would be good to go, but unfortunatly, i havent been able to find that yet.. and im thinkin about runnin NOS.. how hard would that be? i ordered injectors already, got that out the way..

 

and also, how can i tell if i have PI heads on my 4.6? will 4.6 PI heads bolt up to a 5.4l? and if i dont have them, what years/models would have them?

are the 5.4l PI heads?
and one more thing, what are good cams to go with on the 5.4?

sorry for all the questions, i just wanna get it done right..

 

99-04 stangs have PI heads, they literally say PI on the heads. Go with a cam setup that is a step higher than what you would have gone with on the 4.6. The PI heads bolt right to the 5.4 block with 0 issues, that is what most used from the factory, the early ones had NPI heads, but they are pretty hard to come by these days.

 

If you're going to run nitrous you need to do some work on the motor or you'll pop it.

Call up bob at www.hiperformancesolutions.com and get your intake. For the motor, jump on www.car-part.com and find one. It's a lot easier to search all the dismantlers at once.

What injectors did you get?

Nitrous is easy as pie to set up but if you're putting a power adder on the car make sure you fortify the bottom end with some h-beams (or I-beams) from www.themustangdepot.com call them and tell them I sent you (the guy that sends all the 5.4 people there). New rods and h-series bearings and you're good to go for a mild nitrous car (125hp is fine with a solid tune, DO NOT SPRAY BELOW 3K RPM with the HPS intake). The rods are 300 bucks but at least you won't have to buy another motor as soon. If you want to use the stock bottom end, I recommend against big hits. Keep it at 75hp. The stock rods give up all sudden like and kinda arbitrarily. No need to tempt fate till you have a built motor ready.

you have a 99 4.6 mustang, you DEFINITELY have PI heads. Apart from that, jarryd's note below is useful.

cams, MHS stage 3 5.4 cams should be nice.

 

Since long tube headers seem to be either extremely expensive or cause fitment issues with this swap, I was just wondering if the Bassani Mid-Length headers would fit???

Let's say a car has a tubular K-memberwould the Mid-lengths fit and offer better performance over the shorties??

 

they'll need to be modified in all probability. Fitment shouldn't be that big a deal with them but they're still going to need modding. It's not really about the k-member as much as it is the frame rails.

 

Did you get that MAF sent out to me?

 

Yep. Should be there pretty soon. I sent it the day after the paypal came through.

 

Awesome. My internals were supposed to come yesterday, but I wasn't home to sign for them so maybe they will show up today before I leave for work.

 

Hey guys, been looking to swap recently and have read a few different things and now im kinda confused. I was looking to put in a 4v 5.4 from a 99+ navi, and maybe run some spray on it. Since i thought the 4R70W fits right up, i figured id put a j-mod, trans cooler, and maybe a stall converter on it. However, ive heard from one or two people that the 4R wont bolt directly up to the 5.4. And when it comes to rods and internals, whats the difference between them all? I know obviously forged is best, but other than that internal wise idk. Any info appreciated.

 

tranny bolts up just fine. Don't listen to idiots. (EDIT: you'll need a proper 8 bolt flexplate if yours is 6-bolt) You might want an upgraded input shaft... there's a lot of tq in the 5.4, especially with spray. If you're going to put a different converter on it make sure that the maker knows your combo will be really nasty torque-y at low rpm's.

replace the rods, keep the pistons, upgrade the bearings to h-series, add ARP main and head studs and OEM ford MLS head gaskets. Figure out your intake manifold solution now. Reichard 4v adapters and a 01 cobra intake should be a nice setup with a stage 2 or 3 cam set. Get the cams. You'll thank me later.

www.themustangdepot.com for rods.

EDIT: If you're going to go 5.4 on your v6, sell the v6 and buy my car. You'll get all the suspension and brakes and other goodies and a built bottom end and you can sell the heads/intake/cams/headers to other swappers to help balance the cost. It'll cost less in the end and take way less time. ( You could also have new flanges put on my headers and then have 4v longtubes for cheap). A 5.4 4v swap + tranny + rear end + fuel system + tuning + extra bits = a **** ton of money. More than the 10K I'm asking and I'll drive my car to you to make it super easy. To make mine a 4v is just a head/cam/intake/front cover swap. Much easier. And I have a 800 dollar clutch package already on the car that you'd definitely need and it comes with a nitrous kit.

 

I agree, the adapters and cobra intake are the best way to go for the 4v. My idea of using the boss 460 intake is cool, but not worth it in the end.

 

**** , how much harder would it be to do the 4v swap? i want the most power i can get N/A

 

it's just a good bit more expensive.. you can get (unported) 4v power from a 2v with TFS heads and a good cam. Otherwise, it's just a 4v swap. Bring your visa card. Everything costs double.

 

Dont intake adapters have a tendency to be leaky? Or was that the 2v adapter plates? And im assuming because you said to change the pushrods and not the pistons, that the pistons will hold up, just not the other things you listed? As sick as your car is red, in all honesty i could never afford it, or sell my V6 which id love to do. Especially considering its a convert. Its not actually all my car, was given to me by parents and they wont want it sold. How much does it take to make a 5.4 4v work, the cheapest way, then smartest way? And then how much do you think it would take to get 400 N/A? Im considering either, throwing it in there ASAP, or taking my time and building the motor to make real power beforehand.

 

the tranny works fine with a stall and the jmod, i did hunters swap and he sprayed it and ran slicks with no issues out of the trans. i have a dirty dog stall they setup for the 5.4 in his car in the for sale section...

 

4v adapters are a little different than 2v thanks to smaller angle changes. Leak issues will still be present but less so.

if you want 400rwhp NA, break out about $9K-$12K, come over to my house and we'll get started on it. You'll need ported TFS or ported 4v heads, a FAT cam set, a ported HPS or Boss 5.4 intake manifold and longtubes, twin bore TB, 90mm MAF, big CAI, windage tray and a really good balance job. We'll need to get the motor singing up around 6800rpm. The TFS head combo might not make it all the way there but it'll be within spitting distance if you pick the right parts.

 

New goodies!
