2003 excursion 5.4l questions

I inherited an x from my dad and there's a k&n intake and a Gibson exhaust on it. Is there anything I could do to it. I was thinking turbo or supercharged but I don't know of any turbo headers or kits that are made for the 2v 5.4. Or maybe its 3v (please help)

First Welcome To FTE. This place is a great resource.

Unless the engine was swapped its a 2V. Best thing is stay away from modding the engine unless its to replace the y pipe with one from either 5 star tuning or SPD performance. If you really want it to get up better check the gear ratio in the rear. Alot of the V10 and 5.4 members talk about the 4.30's or even a lower gear if using oversized tires.

OK so its a 2v that's what I thought. So I should get a y pipe from 5 star or SPD. Also get better gear ratio thanks a lot because I can't find any info on my excursion because I have the 5.4

Check the door tag and then in the tech folder is a thread on decoding what it came with. Is this a 4wd or 2wd?
