I think thats the same supercharger used on SRT6 is also used on some Buick FWD cars, with maybe some changes to the housing of course. There are a ton of pullies made for the Buick and Pontiacs which I wouldn't be shocked if they interchanged too. Being GM aftermarket parts they sell considerably cheaper than EVO or SI offers. The only question is do the belts match up on the grooves.
