Ok so i have a 90 turbo miata with the 1.6, I was thinking of taking the greddy turbo kit off the car and going back to stock kinda. My question is do i have to go back to a stock fuel pump(walboro 190hp) and do i need to take the begi fmu off, i plan on selling the kit and buying a set of cams.

Also who makes a good cam?

if i leave the fuel and begi on will the car run ritch(note i am still running 1.6 injectors)

It will run fine with those still on, unless you raised the base pressure with the Begi. The pump just allows you to push more feul to support higher pressure or larger injectors, and the Begi is a boost riser, so no boost, no pressure rise.
