I was in the same boat a while back and came to the realization that few things are needed for the 7afe with out spending thousands and thousands. A basic spark plug/ wires/ KN filter/ full exhaust/ short shifter for starters. If you are more hardcore and want to step it up i'd do like others said and go step 2. Port and polish, forged pistons, clutch, flywheel, fuel management system, ignition. if it isnt enough, level up with a TURBOOO. Despite all this work, it'd still be very expensive which is why i just decided to just maintain the car and keep it workin along with some rims/tires and the above work before step 2 until i have an extensive amount of money before i enter the world of turbo. hope this helped
