Well I'd start with the fuel system. A larger fuel pump like a wlbro 255 or even a 300zx fuel pump. A fuel pressure regulator (Aeromotive has some good products), and some larger injectors (MK4 Supra 550cc injectors should be sufficient). Something to control the fuel like a Super AFC (fuel computer) at the least. A stronger clutch to handle the power and torque. An LSD if you want your power to make it to the ground better. Boost controller (optional). Fuel cut defencer. Better intake. Full exhaust system (3") to include a y-pipe.
I think this should put you right in the range you're looking to be in but there are some other things I would look into getting along with this type of setup to be a bit on the safe side. Like some good gauges to monitor boost, exhaust temp exc. Larger radiator for better cooling and even better intercooler. I don't think I missed anything. Let me know if I did guys.
