Aside from doing it right?! If you wanna ignore that the car is 17 years old and go straight for the performance. Then, I would say full 3inch exhaust eliminating stock turbo elbow ($700), Intake($150), Manual Boost controller at 12 PSI($50). That should get you fairly close.
You said you had 3k to spend though, so I would personally replace the HGw/ARP Hardware, Replace most of the rubber in the engine bay (Radiator hoses, vac. lines, belts, etc...), new clutch package, flush/change all fluids in the car. Then, Full 3inch Exhaust, Intake, EBC, Lex/550's, Walbro, AFPR, IC HP, IC. Goodluck.
