A single turbo will flow tremendously over upgraded twins at the expense of low end torque/power. If you're looking for maximum power, this is the only way to go. You will need a new downpipe, your intake can go out the window, but from what I understand, the intercooler can be kept. Max power potential only limited by fueling and the block holding together.

I had a Borla exhaust on my 350Z and absolutely hated it. Unrelated, but figured I'd throw my two cents in.
+1 could not have said it better though intercooler piping does need to change
