well definitely cant use the fuel pressure regulator from an LT1 but the syclone pump (and probably even the LT1 pump) is definitely capable of 60psi. The FPR at the end of the injector rail is what sets the fuel pressure, you have to make sure the gpm rate is enough for your engine but again, a turbo syclone engine will likely use more fuel than a mild ls or lt1.
