You should start upping your fuel when you start upping your boost. It's always better to be rich than lean.

You don't have to worry about your fuel system until you have full exhaust, IC, and 14.7+ psi. When you hit that stage then you'll need a fuel pump and bigger injectors because their duty cycle will be in the 90s. Assume that you already have an ECU

no intake meaning you're not running anything before the turbos?

if you don't have an air filter, your engine will turn to **** very rapidly. Rotaries don't tolerate ANY dust or dirt in the air. SO go ahead and don't worry about fuel mods, you can do that AFTER the rebuild...

well if someone says "no intake" i take that to mean NO intake, as opposed to "stock intake". Sheez...

That's a popular mod for cars with speed-density computers here, just take the whole intake assembly out, sometimes just running some dryer ducting to the front of the car to get cooler air.
