The best way is to STOP YELLING.

And ask the guys in the engine section SR20DET RWD forum is the best place for questions like this. But larger compressor, larger injectors, tune and trimmings.

If you are looking For the best bang for your Buck here are some newb things I did. First thing get rid of that stock fuel pump! Stock pump can't support anything over 280hp. E bay walboro 255...or from 300zxtt! Cams from sr20de are slightly larger junk yard from infinity or a Nissan ser. next is Turbo and injectors. Turbo from s15 can get you by. If you can afford a gt series Garrett that will be best. If you plan on spending money on Injectors remember denso,nismo,tomei, are all the same! Denso is cheapest. Next is a tune. If you use stock Mafs it easily maxes out the voltage at 5v. I'm not saying it can't push 350hp but a n60 mafs can easily support that much airflow. If you upgrade injectors or mafs you will have to at minimum get a enthalpy tune. With bigger injectors drivability will be an issue with out a tune. Also if you do a Mafs upgrade the car wont even run without doing a tune as well. If you send your Ecu in they can do all of that just tell them everything you have done and vuala! If you pull the cover and your rom is removable then you don't even need to send in your Ecu! Just tell the company your upgrades and they can send you a chip(rom) for half the price. That way you can still drive your car till you do your upgrades.
