If you're on a budget just go a Kando T67 or TD06, Yellow Jackets will be fine, run series 2 yellowjackets because they have built in ignitor's. Injectors 1000cc Injector Dynamics, cheapest ive found so far are from Lewis Engines. Plenums...depending on budget, ebay FFP, greddy FFP, plazmaman plenum to keep you're long runners. Throttle body 80mm is MAX you'll need. Exhaust manifold, porting will cost almost as much as a 6boost.
EDIT:
injectors flowing more than 500cc/min are usally low impedance injectors because of the faster response times of the peak and hold pattern
and it depends what fuel rail you run, most common is 11mm and you cant beat ID injectors.
