Well its very hard to find housings in great shape for a rebuild, they are the items that I would buy new. The cast irons are usually the most reusable part, depending on the stepwear. I prefer carbon apex seals myself, being that if you use these, they wont destroy your housings should they break. They will give you lower compression than steels, but they seal well at high RPM's. The inner and outer oil control rings can be reused most of the time, depending on how much wear they show. Corner seals depend on the wear also, most of the time they are junk, easily told by the wear groove they get from the side seals. If its a groove, its garbage. If its a shadow, they are reusable. I could go on and on, but I get the feeling that you wont be getting this deep into the build, unless you do it yourself. If you do, I'd be happy to help you with more info.
Also its my understanding that you would have to have a standalone to control that, unless you do a blowthru like Dan is talking about.
damn
