4g61 fuel pressure

91GSR

I have searched but I cant find the info I need.
1) What is the base fuel pressure for a N/A 4G61?
2) Is the fuel pressure the same across the rev range?
3) Is the fuel pressure regulator a step up design (holds a pressure till a certain rpm where it then steps up the pressure according to the vacuum pressure)?
4) Any benefit to a rising rate regulator on a N/A 4G61?
