Default Suggestions for more power

Im runnin a drag gen 3 kit with a t3/t4 57 trim .63a/f makin 300 whp, im looking to make roughly around 400whp to the wheels. Can my turbo support that, what turbo should I look at for this requirement, ive never really studied turbo sizes etc. Should I change my intercooler to a bigger one, ive already gotten 2.5 inch custom piping all around(Not installed because of possible more modding). If I do change my turbo do I need to change my turbo manifold cause im running a full sized fluidyne and fal fan with limited space.

That turbo (especially from Drag/Turbonetics) is good to a MAXIMUM of 420whp or so, and that is with over 18-20psi on the turbo itself for the GS-R. The intercooler that comes with the Drag kit will start to heat up after about 380whp or so, and be heat soaked. The manifold can hold, but that is depending upon if you're looking for more peak power from the setup or still slightly responsive. With a Full sized fluidine radiator, your options are limited, but expensive other than what you really have right now. As for turbo choice, this is where things CAN get hairy because you will definately need to change the downpipe to accomodate for a bit more power. I have a few turbos that would make over 475whp without needing to change manifolds, but anything over that, and you'll need to at least go to an "E" cover if not an "S" cover. The GT3257, GT3540S, SC61 and the like could all easily work with your manifold, though the clearance would be pushing it. The SC61 is much more peaky than the other turbos listed here, but again, your budget will determine what is feasible for YOU... Don't go for what just a bandwagon says works. Look at the type of power and response YOU'RE looking for
