but I have a few questions as to what else I need. Im not too sure If i need a fuel management system, some people tell me yes some people say no, now my car is also a stock type-s Except for the turbo HKS Hi- Power Exhaust. Anything else I should go for before I buy this thing?

Fuel pump and an FPR.

RFLs are shit...dont get them, also there are a lot better EMS systems like AEM. The turbo isn't exactly a great one for your setup, Evolution wastegates aren't great, get a Tial. Look into a KTeller 3" exhaust because they're a great turbo exhaust and are widely used.

What kind of manifold are you using??
