More power, better torque, and also a new 3 valve concept! That’s what Ford came up in 2002 with the new 3-valve 5.4 L engine. If you are trying to find some performance improvement upgrades idea, then today’s discussion is going to really interest you. Because we have gathered quite a few ones to talk about.
Let’s find out some of the best ford 5.4 3v performance upgrades that could be your best bet to consider. Keep On Reading…
What Ford 5.4 3V Performance Upgrades to Make?
You can consider going for a fuel pump driver module, changing spark plugs, getting ignition coil upgrades, bigger throttle body, timing chain kit, cat-back exhaust system, and fine tuner. There are more areas that can get an enhancement and we’ll shortly include those first in the next segment.
Repair Based Ideas on Upgrades of Ford 5.4 3V Triton Engine
Target Upgrading the Ignition Coils
As we are here to talk about upgrades that could be done to the engine, it’s mostly solution-based to problems you could be having. And the most common one has to be an ignition system. Ford 5.4 triton actually comes with a COP or coil-on-plug system for this.
For Your Information – COP design means that each of the cylinders would have its own separate coil. And it would stay right atop of a specialized spark plug.
The automobile industry is right now head over heels for this COP concept. And it’s true that the design of COP is super-efficient. Something capable of giving fantastic independent control. But then again, the coils are at high risk of facing failures that are mostly in relation to heat.
And that’s the reason why most trucks are going to ask for quite a few replacements throughout their existence.
Now if you want to really boost the ford 5.4 3v performance then your first task is finding out if the ignition system is having trouble, which symptoms will help you to confirm. And if it’s likely to break down sooner, get the part upgraded or replaced as soon as possible.
Some of you may wonder, why would coil failures happen. Well, it all comes down to the coil boot. This is basically a rubber piece. And it’s in charge of covering a spring, that has to contact a prong to spark plug.
With passing time and usage, these would go through deterioration. And there will be weak spots noticeable in the rubber. Eventually, this would result in a spark jumping the cylinder head. And that should only be the spark plug, which causes the issue.
Another possible issue that can raise is, spark plugs filling up. There could be nearby leaks causing oil and coolant to make that happen. And this would further make the spark to a short cylinder head. The internal ignition coil failure becomes unavoidable that way.
You Should Take Quick Actions If You Notice These Failure Signs with The Ignition Coil
- Transmission issue or slight jerk/bucking noticeable.
- 55mph crushing up in overdrive.
- Misfire of a cylinder with the load.
- Accelerating problems.
You must replace the ignition coils and it’s fairly simple to conduct by the way. After diagnosing the misfired cylinder, you need to change the ignition coil and spark plug. And you must not go for any poor or cheap aftermarket coils for this.
The Motorcraft Set of 8 Ignition Coils DG-511 and 8 Spark Plugs SP-515 PZH14F would fit perfectly for such need. It comes with abrasion and corrosion resistance, a great durability factor even in tricky weather, and is pretty premium. So maybe you want to give it a look or find something for yourself.
Performance Upgrading of Ford 5.4 3V By Changing the Spark Plugs
The next thing that needs your attention would be to spark plugs. And you already know it’s the parts that are specialized and hold the sensitive coils. The plugs usually need to protrude downwards through the combustion chamber head. And this is whole because of the combustion cylinder’s design.
It was ironic to happen since 2 valve 5.4L version. As the spark plugs would just blow out of my head. But then the 3 Valve had it break off in the head. You are fine for at least 100k miles. But after that replacement becomes quite necessary for maintenance.
If you go down inside the head, you should be able to find the extended sleeves. And this part basically breaks of whenever there’s too much buildup of rust or carbon. An updated spark plug entered the situation to fix this mess.
For replacement, the Motorcraft SP-515 Spark Plug can help, which is easy to install except for a few areas that could be tight to access.
Upgrading The 5.4L 3V Fuel Pump Driver
The next 5.4 3v engine improvement scheme that we are planning to suggest is about the fuel pump driver of course. With the aging of your model, the fuel pump driver module is very likely to face a failure.
If you don’t already know the module basically is in charge of controlling the fuel line pressure, and it does that through pulse width modulation.
You would be able to locate the fuel pump driver module beneath the vehicle. Just a bit above the spare tire that stays connected with the frame. The general way was to have the aluminum driver module connect with the steep frame directly. However, due to extreme corrosion issues, it wasn’t really a great idea.
If the corrosion kept going, the aluminum housing would be eaten by having a hole in it eventually. And that means exposure to road grime, water, and whatnot, being a huge risk if getting in contact with the electronics.
The module will face a short out for a while and this would result into
- Issues with driving.
- And then the smart junction box permanently catches damages.
- Later there was an updated module that Ford came up with allowing the stub mount to have some space away from the frame.
Now the common symptoms that tell there are issues are
- Hard starting every time.
- Sometimes no starting at all.
- Power lacking noticeable.
Keep in mind due to lack of fuel pressure, the drive module may have the main problem causing the scene. It could also be the leading wiring.
You can try the Dorman 590-001 Fuel Pump Driver Module which would get you a better response time and comes with bushings that would allow the module to stay a little far from the frame to avoid corrosion.
The 5.4L 3v Variable Timing Chain Issues
This one has to be the scariest issue with certain late models of 5.4L Triton. And it’s about:
- Timing chain issue.
- Tensioner’s problem.
- Variable valve timing problem.
There’s a certain sound of the 3 valve 5.4L Triton that most would be able to identify. Especially when you are driving with light acceleration. This gets even better with having windows down and fulling towards a drive or alley down ride.
The three prime reasons for such happening are
- Pump failure resultant low oil pressure.
- Not enough services are done to it.
- Failed phasers and tensioners.
At some point, the worst would happen as the engine would get hot and become unable to maintain the timing. Eventually, this will result in a rattle and rough ride.
A few seconds afterward, you may notice the rattle is not there. However, it could also be possible the rattle will start until you decide to rev the vehicle.
The most likely problem is usually low oil pressure though.
Then there’s also the failure of timing guides, which usually happens because the chain keeps slapping. And everything turns into a huge mess from there. The mechanism is quite complicated with these issues, and most of the time you will need expert help here.
So, one of the key performance upgrades of ford 5.4 3v to make sure such awful engine failures stay away, would be changing these components after a certain period of usage.
The phasers and timing chain will need a new one as soon as they fail to serve any better. Some people however also consider just deleting the VCT altogether. That’s not a hard thing to do though.
Yjracing Variable Camshaft Timing Chain Kit can be a great all-in-one option to give a go.
Upgrade to a Larger Throttle Body
To kick off the mods, a lot of folks would consider going for a throttle body upgrade, which is something that gets mixed views.
For this, you need to take the stock one out and just get in place a huger throttle body. It’s a precision fit part that is often also made of aluminum and comes with CNC machining. For systems that have panting exhaust mechanisms, this will be such a relief. Also, there will be an improvement in power
With a better and bigger throttle body you are supposed to enjoy these benefits
- The power-pumping oxygen would be better drawn to help the vehicle go further.
- Additional benefits than just increase with horsepower upgrades.
- Throttle response to the boot will become faster as well.
Also, for aspirated models, you should be going for an extra f150 throttle body upgrade that includes a spacer.
And keep in mind that even if the upgrading of ford 5.4 3v with a bigger throttle body is going to bring some good benefits, a spacer will just boost everything to another level.
It would be able to get up and over high places such as mountains. The throttle body upgrade alone is great for bettering the air-to-fuel ratio, no doubt.
However, with the spacer, there won’t be annoying droning resultant silence. Also, any weird whining will be out of the place. And you’ll have a driving session that’s not just powerful but also pretty peaceful.
BBK 1759 80mm Throttle Body is one popular aftermarket option that comes with the OEM standard exceeding components and an easy replacement scheme overall.
Think About Getting Cat-Back Exhaust
If you are really up for having the massive horsepower upgrades and at the same time want to ensure a great torque achievement, then this could be it. This was also part of our ford f150 5.0 performance upgrades suggestions. Getting a car back exhaust, a fresh one will give you some impressive upgrades for sure.
Of course, you need to pick a rip-roaring option that can take place of those sputtering pipes.
You can think about mandrel bent tubing. This way there would be low back pressure. And the exhaust flow will be enhanced as well. The fuel efficacy will also most probably increase and it should be a noticeable change after the upgrade.
Make sure you pick something that comes with the necessary hardware. Also, clear instructions are a must if you’d like to conduct things yourself. Flowmaster 817522 Cat-Back Exhaust System is a pretty well-known one.
Go For a Tuner
Another ford 5.4 3v performance-enhancing route we’d like to let you know about would be an all-in-one tuner. The areas that are hard to reach with the wrench, that’s where it can help you with and fine-tune would be simpler like near before.
A simple tap on the screen or in some cases a button presses what it would take to just get it triply digited, the horsepower as well as torque.
Some chose to go for their own settings while there’s also the option of preset f150 horsepower upgrades.
