I was ready to purchase a supercharger from Kenne Bell for my '04 4x4Expedition, but when I called they told me that they have discontinued all superchargers for trucks/suv's. I am trying to avoid purchasing a take-off harley because I have been told that I will run into wiring harness issues. Does anyone have a suggestion for a new supercharger to help with towing? Whipple also does not make one for the '04 expi with the 2v 5.4l, so other suggestions would help.

Thanks

 

You will have no wiring harness issues...

 

I have been told that the wiring harness' are different enough between the f-150 and the expedition that I would need to find someone to modify the harness. I tried checking with two local ford dealerships, and they were no help. Will a harness from an f-150 work with my expi 4wd? That has been my hurdle.

 

just get harness with the take off unit you buy, that is what i did. Plugs right in your vehicle

 

L swap!! Not a real big deal, but well worth the effort!!!

 

Has anyone with an expedition made the swap? I have been told that the swap with another f-150 is pretty straight forward, but there are enough differences with the expedition that it creates problems. I just want to avoid putting a couple grand into something that may not work.

 

I don't see it being a problem. What would not work? There are a few that have done the swap. And I have done one in a F250 also.

 

I've read a few posts on other forums where Expy owners have done the swap without issue.

They had Mike Dunn help them, you can touch base with him to be sure.

same truck from the doors up, no different.

 

Ok, so if I can get past the wiring issue, can anyone tell me the main differences between the harley/lightning set-ups. Would one application be better than the other?

As always, thanks.

 

Color and the Harley upper blower pulley is bigger, therefore creating less boost in stock form. That doesn't matter as you can make up for it will a lower pulley anyway. They are the same animal and neither one is better than the other, other than color, as some Harley's came Black.

 

Thank you.

 

doesnt TROYER still carry the m90 charger for our trucks?

 

Even if he does, the M-90 is still too small a displacement unit for a 5.4. Go with the Lightning H/D swap, it's an M-112.
