Tried searching for this, but came up with nothing. I am looking for how air much the stock intake system flows. As another question, how much would an unmodified 13b engine require in CFMs if it was set up with carburation?

It doesn't work like that. The CFM flow rating for intake components depends on the pressure. The CFM flow requirement for a rotary enigne is based on the equation of CFM = (CID*rpm*Ev)/1728. However, this isn't going to do you much good because 4-barrel carburetors are usually rated at 1.5"Hg vacuum for piston engines, so you cannot use this rating for a rotary engine. Rather than crunching numbers for your engine and trying to re-invent the wheel, it is probably better to just look at what other people have found to work well over the years. See the Racing Beat and Yaw Power web pages for carburetor recommendations.

Okay, cool. I was trying to find an easier way of doing something with available parts. We are trying to frankenstein a fuel-injected 13b into a B2200 and basically in the process turn it into carburation. We have no direction right now, lol. Thanks for the help.

Here is some better direction: Haltech, Microtech, Wolf, etc.

FYI, with a universal EMS (Haltech, Wolf, etc., but not Microtech) you can buy one EMS and another wiring harness, and that way you can wire up two cars and swap the ECU when needed and change out maps. The Wolf can be changed from one car to another in this manner in about 5 minutes, and I would imagine that most of the other brands are nearly as easy. This is a really nice setup for someone who only drives one vehicle at a time, would like a lot of performance, and doesn't want to waste money.
