I have no idea, of what the system consists of.., as far as components are concerned. Are you serious...The head is different? I didn't think it had anything at all to do with the engine of the car, aside from either a bolt in accessory pump, or maybe an under-hood electric pump. The money, is of no concern for me, however, the hassle, sounds like a lot more tan the whole thing is worth. I was thinking it would be a fitting addition, to the trailer hitch I have planned for the car. I did, however, think it would be more closely related to the system in My Oldsmobile wagon, with an electric, underhood, fender mounted pump, and sensors in the shocks. That is a closed loop system, independent, of the rest of the car....Maybe I'll stick one of those systems in the car instead. Lotta old G.M. wagon parts out there.
