I recently met this guy with a 97 cobra and he has a vortech v-3 blower on it. He told me that he spun his camshaft berring and is parting out his car. He said he'll sell me his blower for 2k. The supercharger has around 40k miles on it. Would it be dumb if i bought a used supercharger or no? He said he changed the oil in the blower ever 5k miles with royal purple, and that he would give me everything from the kit except the t-rex fuel pump and the injectors. Would it be worth the 2k ?
