Ok, As some of you may know that my car has about 151,000 miles on it,and i would like to supercharge it. exactly what would I need? or is it even possible? I kind of want to make the car more fun but I dont want to have to buy an whole new engine. Would supercharging my J30 be safe after so many miles? It is my DD so i would run a low PSI anyway but just having a super charger would be great. thanks in advance.
