Maybe in a junkyard. You can buy a very big and capable single turbo for around $500 (BW S475 comes to mind).


Keep this in mind: The 5.4L can spool a very big turbo for its displacement. At 330 CID it'll pump up a turbo faster than any SBF or SBC of equivalent displacement. Don't get hung up on some outdated modes of thinking where others will say a 76mm turbo is too big and will lag. It isn't and it won't on these engines. You can probably find a very good deal on a small, medium, or even large frame turbo in the 70 - 80mm range that will support plenty of power with room to grow, be cost effective, durable, and will spool plenty soon enough to fry the tires at will.
