a misconception is that newbies think "more boost will automatically mean more horsepower"
you have an 04..that means you have the plastic stock bov. get a jdm one or the evo 9 bov if you havent already so it holds boost better.
turbo manifold will hardly do anything with your stage.
i would get a hi flow cat to go along with catback and downpipe. after that get walbro fuel pump as an insurance. get your car tuned and while getting it tuned...set it to about 23-24psi so it will taper to about 20-21psi. that should be a good set up for you.

i forgot, may be youre going to have problems wit your housing, and have to put the blow off valve from the evo mr jdm, is metal and the housing you have to put the piping kit for the intercooler
