Hello everybody, Figured I'd start my build thread. Currently, My DD is an 02 GT with a 5.4 2v/5 speed, with HP292 Cams, All the basic bolt ons, with an AJE K member, and Tuned by me with the Delta Forces Commando Unit. It Runs and drives great. I got a really good deal on a 2001 Navi 5.4 with fairly low mileage and decided to swap yet again. I've already pulled the unnecessary Navigator parts off the long block. Getting ready to put a new Oil pump (because why not? I'm here), And ordered a new timing chain and guide kit. Waiting on my Coyote intake to come in. will be using the MMR Lower adapters with a TB adapter I'm going to make in the shop at work, so I can use the 75mm BBK I already have. Will be building some kind of custom Alt bracket so I can mount it rear facing. Not quite sure how that's going to play out yet. I'll to keep this active until I'm driving. I'm sure I'll have lots of questions for you swap veterans lol.
2002 Navi 5.4 Swap
- Thread starter RyanBell
- Start date
As kind of a rule, I try to do 1 thing every day regardless of how small or large the task. Yesterday, I cleaned the engine really well and started priming and painting the block. I do love Ford Blue lol. The Block will be Ford blue while the Timing cover will end up being Silver. And Wrinkle Ford Blue for the Cam covers, the oil pan will be replaced with one that isn't bent to hell with a stock Black one. The Last pic is my current 5.4 2v Set up.

With the 2v swap, its extremely straight forward. I bought a set of intake adapters off ebay. and cut a tiny hole in my hood to clear throttle linkage. Had to extend the mid pipes to reach my xpipe. I used stock manifolds and stock mounts. I tune it using the Innovate LC2 AFR monitor, Fuel PSI, and Vacuum gauges with the Delta Force Commando. I originally swapped it using the stock K member, now I have an AJE Tubular and it gives soooo much more room lol, can't believe I didn't use get one the first time. It is my DD and gets between 20 and 22 mpg. The only reason im going 4v is because I got a really good deal on the 4v. You will not be disappointed going from 4.6 2v to 5.4 2v. I have never had it on a Dyno but the one time I did manage to run at a track, the best I could pull on a very hot 101 Degree day was 13.08. I think with a little suspension work and a better set of tires it will easily hit high 12s with me driving and I dont have great reaction times.
Another thing, I did notice that with the Tubular K member, and the new mounts, it did lower the engine about 1/4 of an inch. it doesn't sound like much but now I can put my fat fingers between the driver side cam cover and the brake booster lol. Still going to use a k member spacer for the 4v tho Just in case
Sweet! Thanks. I just put a put k member in my car I'll have to upload pictures looks good. I was worried about drop and clearance on a couple things suck as steering rack with aftermarket headers. Holy s**t 20-22 mpg? And only a 13 at the track? Not trying to saying anything about your tuning ability but did you tune it for max power? I'm mind blown by that lol. There had to be a lot of power left in that motor. I'm going more towards track only solid mounts new 4r70w trans. It sucks Ford restricted the 5.4 to the same power as the 4.6 a lot of potential was left on the table. I plan on 4v swapping mine in the future but I wanna get a f150 swap the block for a teskid switch the 2v heads onto that and put new 4v on my mustang with the 5.4 lol.
Lol I've got a very safe tune in it. I love driving it and really wouldn't want to lean the ol girl out and kill it, I have other vehicles but use this one as my Daily. Ill be pushing it a little harder once the 4v is in, but this car is built to drive, not to race, the only reason I went to the track was to spank my little brothers 2013 SS Camaro. his best time wasn't against me but he pulled in a 13.15. not too bad for a almost stock Camaro.
Got the engine cleaned, primed and painted on my days off. New high volume oil pump installed and all my new timing chains and guides installed. Still waiting on MMR to send the Intake manifold adapters. Now that I'm back at work I plan on working a little more on my Throttle body adapter.

Got my TB spacer completed and Bolted on yesterday. We spent a little over a week machining it out, and making it look good. And after all was said and done, when we were trimming the excess off at the Bandmill, the blade was a bit wore and cut the driver side of the plate at an angle. Eating into the Countersunk holes mating the spacer to the manifold lol. Oh well, still works and still going to use it. For now. Finally got shipping notification from MMR that my intake adapters will be here on the 12th. The TBs pictured aren't the one I'm going to use. The really dirty one is a Stock f150 70mm one and the other is a ported and polished 65mm. Just used them for Mock up. Ill be using my BBK 75mm when it goes in my car. I turned it 90 Degrees because the bolt pattern for the TB actually fit between the Coyote pattern like that. And it will allow me to run my Cables under the intake, hiding them and the linkage. I plan to pull it back off and try to mend the problem on the right side of the plate at the milling machine, Id hate to just start over now lol.

Ok. Got the MMR intake adapters in yesterday. They are pretty, but not a complete product. The Countersunk holes that are drilled for the Capscrew bolts to hold them down aren't a large enough diameter for the heads of the actual capscrews they send with the spacers. So they have to be drilled out a tiny bit to open them up. I did mount them and think; Hey, MMR is a big company. There is no way the shipped this out unless it works. So I test fit it and felt like I was going to strip out the threads in my head or break the damn bolt. I will be drilling them out today. Also, I haven't seen anyone discuss it on any other thread. The manifold doesn't just drop into the 5.4. Its a tad to wide. AND it has 2 plasitc dowls molded under it on the passenger side that need to be removed. the MMR adapters aren't drilled out for them. I Hit them with a hammer and chisel and they popped right off. I have pics of them below. I took a Razor knife and shaved the outer Rims of the injector bosses down on the intake manifold its self because it will not just drop down between the heads without doing so, this is also pictured lol. It took a little bit of shaving and test fitting, and shaving, and fitting. But it is finally able to be put on and pulled off easily. Also the factory bolts are to long and go through the spacer and contact the head. MMR sends several bolts. In order to use them, I had to knock the factory bolts out of the bolt holder and use the shouldered Capscrew. Pics below.

However, even with the AJE K member and what AJE says are Mounts that lower the engine 1\2 inch and 1\2 inch K member spacers, I still hate it. It just doesn't fit in a way that im comfortable with. Also, I keep reading that BBK headers can be made to work LMAO that is 100% BS the driver side header would have to be cut and rebuilt to the point that it could no longer be considered a BBK header lol. As you can see Pictured here, even after I cut 2 tubes and mashed them in a good bit. they are still just no going to work. I have Installed 1 inch spacers and did get plenty of room for the master cylinder. Highly suggest this to Anyone doing this swap. Yea some say you can make it work without spacers but not practically.
That being said, the passenger side fit like it was meant to be there lol. Literally a perfect fit. I will be pulling the long tubes and going with a set of CG fabrication Forward facing Turbo headers now. Ordered them already and should have them in a few weeks.

There again I used stock cobra manifolds.......after researching power gains and clearance issues. I just didn't think it was worth the extra $. Also my build was more budget minded when it come to intake and exhaust, also I wanted to modify as little as possible so in the event I need parts a trip to the junk yard would be all I need.
