Im looking to add some reliable power......

[Deebo]

........to my 97 Expedition. What mods could I do to the motor that would add some significant RELIABLE power. Im kinda new to modding my truck but not new to modding my car. What advice do you guys have?

to bad it isnt a 98. whipple industries has a supercharger kit that bolts on in a day. making the tired 250-260 hp 5.4L wake up and produce 480hp that is daily drivable. cost around $3200.00. or you could add some headers, cool air intake,throttlebody spacer,power programmer,chip, goes on forever....... goodluck

i think the basic Intake, Header, Exhaust upgrades will start you on your way..then go from there.

I've already added a catback exhaust and I plan on adding a cold air intake, and headers. Im seriously looking into a supercharger. What mods to the shortblock would be necessary to make sure that the power I make with the blower is somewhat reliable? Would a rebuild be necessary with all forged components? Or do I need to just make sure my gaskets are up to par? Id like to see at least 400 rwhp reliably. Is this realistic? Thanks for the help.

well its imple none. no mods. just bolt it on and hold on! 400rwhp is definate. the kit i speak of is the most reliable kit i have ever read about. if you go to ( whipplesuperchargers.com ) on the home page about half way down you will find all info you need.

ps. i just got a reply on this kit today from whipple's sales department seems i have made a boo boo, the kit is around $5500.00. guess i have to wait till tax time.

Whats the difference between the 97 and 98 5.4L? Why would the supercharger fit the 98 and not the 97?
