First of all, please lay off the caps lock. In the Internet world it's considered shouting and rude. I'm sure you didn't mean that so I thought I'd give you the heads-up.
As for turbo kits.....
Your best bet is to search the archives for broad info and as you get some idea what you think you are leaning towards and what the issues are, you can ask better questions and get better answers.
You should also join the SR20DE forum and the SE-R mailing list. They both are terrific resources for this information. They both also have archives so you can review a lot of excellent information in a reasonably quick fashion (probably take you a few days).
You might want to check out this website. This guy posts here too, but he does SR20DET drop-ins and bolt on kits.
I don't know about that kind of HP though... you will probably need more than just a DET, new pistons, injectors, larger turbo, etc...( I really dont know, but just an partially-educated guess:-\ )
