Default upgrade turbo but also scared

I ve been buying many things for my 05 usdm sti in order to change the turbo. I dont know why when I have to go to this step I got scared.
First I have perrin header, up pipe, complete exhaust, brakes, aps inlet, HKS bov, pwr radiator, cold air intake, walbro fuel pump.

Right now I wanna change the turbo, I been reading a lot about 20g, fpgreen, fpred, 18g and I can not decide which one is the one I am gonna buy. I also know I have to tune the car and use tgv deletes to take advantage.

My question is:
1. which turbo is the ideal one to upgrade the oem one in roder to have 380 or 400 hp without feeling too much lack.
2. Do I need to buy fuel rails, inyectors, fuel pressure regulator
3. Which parameters do I have to be aware when I tune the ECU
4. Is it possible to run the new turbo without changing the original tmic
5. I dont wanna use meth or water inyection cause I think this damage the engine.
Thank you

4. OK but I would go Front Mount personally
5. If you stay TMIC then yes, if FMIC then no.

1. Do some searching tons of posts on this.. Tons.
2. You need Injectors no way around that..
3. Just by the question your asking do not touch the ECU bro...
4. It depends on your goals what you want for a setup, cash etc etc etc.
5. Meth does not damage an engine, thinking meth is a set it forget it mod is what damages engines..

do some searching, wait your fav mod is the Green.. did you do this already??

For 380-400WHP on pump well where you at 91 or 93??? Your gonna have to go bigger then a 20G and possibly a Green if you truly want 400WHP that is my goal and I am doing a DOM 3.0R with Meth.. Search Brother

Ok thanks. Every one. Well gt52 I think its kind of difficult to install cause Someone told me that I have to change some parts that I already changed.
I just wanna check which parameters is gonna change the tuner thats why I ask. I know I dont have minimun knoledge to do it by myself.}
I have the green on my hands but I didnt install yet cause I am not completely sure about it. If I decide for other turbo I gonna sell the green.

Explain to me cause I dont understand what youre trying to tell me (sorry My english is not so good).
Somebody told me that if I wanted a rotated turbo I will need a kit because the turbo inlet is not gonna be under the manifold. It gonna be next to it. Then the downpipe is not gonna match with the turbo output (i dont know how to say it in english) because the position is different. Is that right or he is lying me
