i would do a turbo set up first, before the vtec head simply because it is more of a power gain to begin with, and your turbo and all will fit if you go vtec anyways.

if you wanted to, you could pick up a used greddy kit with intercooler and all for relatively cheap and be good with that, since the motorisnt built you dont want to go crazy anyways. i would then focus on getting it to be tuned and run well, you could pick up some dsm injectors cheap, and you already have some supporting bolt ons to help out.
