42mm turbos are kind of small.With a 5.4 you probably want something in the 60's.Is the turbo off an import? it'ssounds likeyou are going to have to fabricate the headers to make them fit. Anyways, I think your usingtoosmall of a turbo.

42s will be fine, its the compressor a/r you need to worry about. with 42's you gonna want a 1.25 or so a/r with 57's probly .75-.8 with a sinlge 88 around .8-.96. The 42s with a 1.25 a/r should still push 700 rwhp
