S480 turbo ????

So I was running it with an air to water. However there is no real-estate for all this. So now I'm probably going turbo centered and blowing straight into the throttle body and use meth injection. Any thoughts??
Also. It has a 5" outlet and was wondering if anyone found a tight bend 5" 90 or do most of you reduce it down to 4"? I plan on running mild steel. Damn this biotch is super big. I plan on setting it up like this for now and at some point I will modify a hi ram Holley intake and add an water to air core on top the hi ram
Intake.
