folks -{ do u know what options do i have for upgrading my supercharger boost? I have a D16Z6 93 with a JR supercharger 8 psi (3.4" pulley). I know i can get some boost with a 3" pulley and increasing the diameter of the crank pulley but i couldn´t find anyone in market because JR is not selling this upgrade for my car anymore. Could u pls suggest any brand, webpage?
