My 5.4 Build

Lol
I have one in my garage!


Personally if I were you and going to boost it I would change those pistons. If not keep them and run aggressive cams. Stall it out and beef up the tranny. I haven't read your entire thread so not sure if you e done that already. Lol

 

I have a 4v 5.4 out of a navigator.. wouldnt I need to find out what size pulley comes on it so i know how much boost is going to be on it? I wouldnt need an intercooler with it right?

 

Yeah you can always change the pulley to lower boost so that's okay. On the intercooler yes you would need one. Your gonna need that an a heat exchange and a pump. The price is good but it's missing some key parts.

 

yup, and maybe Im missing something but I also dont see a lower intake for it. I see the plate but missing the intake and idk if the kenne bell mounts to stock or not? some of those things new can be as much as you could potentially pay for the lot, thats why its important for things like that. that stuff adds up fast

 

Ill just leave this here

 

I actually posted that a few weeks ago lol

Im thinking ill just stay n/a since its hit or miss with all the extra parts and stuff. Id be close to another 2k into the engine with all the pieces id need.

So 5.0 intake, longtubes, and a solid 91 tune will do me just fine? Thats the original plan lol

 

crap I didnt mean to post that haha, Wasnt paying attention. Was supposed to be a pic of guys just welding on a few tabs to to the navi heads and drilling and tapping some bolts and bolting up coyote intakes to the 4v 5.4

 

Awesome now I I just need to find someone that welds

 

its only a couple small welds on each tab, 3-4 tabs per head

 

I think id rather buy the adapter plates. But ive also read that the navi intake does fine unless youre spinning over 5k rpm which ill i wont be going much higher than that. Idk if the coyote intake would be worth the money.
