Reply With Quote7M-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?
7mge are 250cc
stock big port is approx 187cc
