What fuel pressure do you want from the fuel pump to the fuel
rails for a 20B/turbo? I recognize that you need a fuel pressure regulator to
maintain a constant pressure differential for the injectors.
The "standard" pressure
is 3 bar, or 43.5 psi. Mazda tended to run a bit lower normally, but not
that much, and there's no reason to care unless you're planning to use a stock
ECU. With a turbo, you definitely need a regulator that is referenced to
manifold pressure, so the difference between the pressure in the fuel rails, and
the pressure in the intake stays the same, regardless of MAP. That can be
confusing, so let me know if you don't follow that.
What is the pressure range for the fuel pressure regulator?
See above :-)

You're screwed then... Just kidding
