I have a used ASP Under-drive Crank Pulley for 1991-1998 KA24DE for sale. It is an after-market bolt on which weighs about 1 lb versus about 8-9 lbs for the stock crank pulley (should be good for about 5-8 hp- by reducing rotating mass). This pulley will require newer belts, this does not come with the belts. Asking for $95, thanks
