I heard they quit selling turbo kits for our cars, but I thought they were still in buisness

They quit making them. They found out ssautochrome stole there design and made cheap versions of it. They got mad and said forget it. They only were doing this on the side. I think if you wanted a kit you could probably contact them through this site and see if they can get you one.
