dont be cheap and mod only once insted of having to upgrade down the road.

i would go with:

precision 600 hp intercooler and have ur own pipes made to fit ur car.
tial bov and u'll never have no problems and wount have to ever upgrade.
sense ur fwd i would go with a turbo xs dual stage manual boost controller.

if u want more boost u should look into getting bigger injectors and a fuel pump, but with that u will need something to tune with , once again do it once and get dsmlink.

i think 14-15 psi is max for the stock fuel setup.
just my thoughts.
