or make one.......the rb20 has a built in restrictor in the banjo bolt on the stock feed line, not sure what the size is tho.i made an aditional restrictor for my gt30r by tapping out the fitting into the turbo and drilling a .039" hole in a set screw and putting the set screw in the fitting, works pretty well but i broke 3 bits trying to make a hole that small.
