I have a bone stock 89 lx coupe I was thinking of throwing this supercharger on instead of it just sitting on the shelf but I wanted to know will the stock fuel system with just a 155lph pump and a 12:1 fmu be enough fuel. also should I still go down one heat range and gap the plugs real tight. The supercharger has the newer inpeller and oil cooler and Im guessing it will make around 7lbs or so on this motor. Thanks for the help.
