Is the bbk throttle body recomended in this engine does it really even have any affect they told me its good but unsure about it dont i need a supercharger for this to work properley? And also what kind of mods do you guys recommend me for my truck thanks for the help

 

Ask ten people and you'll get ten answers. For me, it's bang for the buck. I start with the exhaust because you also get that awesome Ford V8 sound. A lot of options based on your taste. I prefer Magnaflow overall for the sound, flow, and they're the least likely to cause droaning. You can do a full cat-back, or go cheap and just install a muffler with a 45° down pipe (aka "dumped"). Though a dumped exhaust will have a lot more noise inside the cab and a bassier sound.

Next thing is a cold air intake. Again there are a lot of options. But they key thing to stick with is one that uses a composite intake tube rather than metal. Metal soaks up engine heat and warms up the incoming air, which is counter-productive. This will also add more sound, so keep that in mind when choosing an exhaust if you plan to go this route.

That's the foundation as far as I'm concerned. A BBK throttle body without these mods done won't see much benefit.

 

A cat back won't net you anything besides noise, get a single 3" exhaust(from y-pipe back) or dual 2.25 mandrel bent X'd exhaust, you get some performance and I'm talking little like 10 horse at 4,000+ rpms.

Intakes are the worst bang for your buck. They bring in hot air which is worse for your engine. They also only net maybe 7 horse AFTER a custom tune atty 4,000+ rpms.. Look into the gotts intake mod. Us cheap and you get the same gains as those expensive intakes..

Bigger throttle bodies are also a big waste unless you decide to go FI.

Also Borlas drone less than magnaflow

 

Thanks for the quick reply i want to get the k&n 57 series i think its called im not sure but its the plastic one not the metal one and lontube headers if theres anyouthere and getting the exhaust and camming it but before the cam i want a god dyno tune is there anything you guys would change about that

 

No K&N intake.
They suck in warm air from engine bay. Which is worse.. Just do the gotts mod.

 

Oh okay sounds good ill kepp in mind while i shop and mod the truck idk about really tunning a lot this engine i love the truck i coulve of dine better in other peoples eyes but this truck really caught my eye i been thinking hard of doing a swap to a 302 boss do you know how hard this is or is there another engine you would recommend instead other then the coyote

 

Lightning swap.

 

What do think is a good price on one of those because a guy here where i live has two one with 64xxxx and one with 101xxx what should i offer i have the money but honestly ive never messed with ford much haha

 

Going 302 would be a down grade, and pretty hard to do. If you want big power do a full lightning motor swap.
Or swap in a N/A 5.4 which us a pretty straight forward swap.

 

Yea i really like the lightning engine of the 02-03 harley & what year 5.4 is the best choice

 

03 with the revised heads would be best. But 99-03 are all pretty good.

 

Alright man thank you i have one from a 01 fx4 my truck is a 2wd do you happen to know if i can keep my tranny or woulld i have to make my truck 4x4 or how would this work sorry for being a dummy im just new with these fords and im enjoying mine a lot but i just meed more power at least 350hp haha

 

You can use your stock Trans, but you need to swap the torque converter.
Man you are set up nice for a lightning swap with a T-56 manual Trans (,i think that's it) from a cobra. That would be sweet.

 

Yea imma stick with the 5.4 for a while and then once i get some saved up money imm switching to the lightning it would be a cool sleeper ill keep you posted with the project & one more question and im done whats the best year of tranny i can get from a cobra

 

Once you have the 5.4 you only need to find the supercharger and parts to swap on it.
I have no idea what a good year is from the cobra. Go onto the lightningrodder site.
For now just swap the torque converter and use your stock trans.
