If money is tight sell the following to buy things you really need:
Greddy style manifold, 80mm throttle body, fuel rail, unknown turbo, OEM ecu, Tomei fuel regulator and all of 9
What you need as a minimum:
Link G4 computer + mac valve for boost control OR PFC + Z32 AFM and boost controller
Decent turbo with (if necessary) wastegate mounted on stock manifold.
Assuming you are running on petrol some 550 side mount injectors
3in turbo back exhaust
Probably a set of new OEM or Splitfire coils.
Good intercooler (you don't say what kind you have)
Good tune
