FI questions from the other side; an xB turbo setup

[Bamboo]

Hey Yarisworld!

So as a fellow 1nz-fe owner, I have repeatedly been told that the repository of much forced induction knowledge for the 1nz lives here.

Here's some pics of my car:




I have modified my box in many many ways, but have not yet started on any performance mods. I recently picked up a used greddy turbo kit with boomslang harness and front mount intercooler setup. It also comes with an AEM FIC for management. Im not looking for crazy numbers and really just want to add it to gain a little pep as well as add another element to my build. I plan to only run 5-6 psi max and from what I understand from everything I've read, stock internals and fuel would be just fine... right?

What are your thoughts guys? Things to watch out for? Things to buy in addition to support this change? Ive installed an NA-T setup in a lexus gs300 so im not clueless, but aside from getting a boost gauge and wideband fuel sensor and gauge, what would you all suggest or advise?

Thanks in advance and looking to pick your collective brains as I re-enter the world of forced induction :D
