basically what everyone else said...you arent gonna find a reliable supercharger for under a grand..the cheapest ive come across are the powerdyne kits (which i have for my stang)...u can get brand new kits on ebay for about 1700. but powerdyne are considered at the bottom of the list of SC's but they are easier to install then the rest from what i have heard (self contained system and no tapping the oil pan). if i were you, like I should have done, was save up for a Procharger w/intercooler kit or a Kenne Bell Roots...also depending if your car is standard or auto, you're better off with a centri SC if you have a standard and roots/twin screw for your auto...just my opinion.
