fuel pressure

[cracker]

much help would be great

7M-GE injectors would normaly be seeing about 38psi at a guess. But they can handle a bit more, not sure how much more. With your engine you probably won't need to wind them up anyway, just go with about 38psi.

I have found most injectors will lock up at between 60-70psi, but should never need to run more than 45psi with no vac to the reg.

Are 7mge injectors bigger than 4age injectors?

[cracker]

7mge are 250cc

stock big port is approx 187cc
