5.4 upgrades??

[cornbeltbandit]

I've got a buddy with a 2003 F250 with a 5.4...he's feeling left out. He's done an exhaust kit and air intake, but still wants to run with my 6.0. I've told him that's a stretch but I knew of some guys (you all) that might have some advice. I'm no expert on gas trucks, so shoot away!

he can run an edge evo on it.. i have that on my 5.4L.. but even then he wont be anywhere close to the diesel guys...

my suggestion is he even wants to come close is to go with a stage 3 roush supercharger kit... it will run him about 6k for the whole setup and installation.... that will get him to around 450hp

Tell him to stay away from T-Body spacers.

They sound inexpensive and promise HP gains but I didnt like how my 5.4 drove when I had it on there.

What was wrong with it? And yeah, he's gonna have to supercharge that thing to even get close to diesels.

Truck felt crisper when I took it off.

Not saying they are terrible, just saying his money could be spent in better places

Yeah I wouldn't get one anyways just because the gains are negligible.

5.4 mod motors are great motors, but they don't respond that well to upgrades. The only cheap thing he has left is a tuner.

A tune will make the biggest difference.

well this is up for debate...

for most people a F150 would be more than enough for the regular person that is not towing on a weekly basis....

I have a 07 5.4L 4wd that i use way more than my f350 7.3L. plus it cost a whole of alot less and gets the same MPG as the 7.3L... then take into account that fuel is 50 cents cheaper as well as less maintenance.

now if i really had to tow something more than 5klbs i would take the diesel....
