Learn to read, "buddy." I said non-turbo, as it the ones that are not Turbo II's. They have 460cc injectors.

Also why do you just need 2 injectors?
You don't know what you're talking about. The stock fuel system on the non-turbos runs stupid rich, which means that when you dyno tune it with some form of fuel controler you lean it out to bring the A/F ratio and thus the power band back up where it should be. N/A rotaries love running lean, but emissions laws amoung other things make that difficult to do.
I regularly make 25mpg. Doesn't bother me at all, and that's untuned.
Our injection systems are staged because two 460cc injectors flow more then enough fuel to fully supply the two rotors to the 3800RPM engagement point of the secondaries. From 3800 and above, the job is shared with the secondaries. The GSL-SE only had two big injectors to avoid this, but their stock injection system is pretty bad in itself.
