there is no way you could get 300rwkw for $7500. Computer, injectors, fuel pump, turbo, manifold, tune, exhaust, intercooler. And that isn't even including putting the motor in. Are you putting the motor in yourself? cause if your not you are going to pay quite a bit to get the motor in wired and running. if you are getting someone to put the motor and do the 5 stud conversion i would atleast budget 5 grand cause you are going to need custom tailshaft, custom gearbox crossmember, exhasut front mout. So that leaves you $2,500 which will get you a computer injectors and fuel pump. That will give you around the 180-190rwkw with an auto.
