My ebay kit (ssautocrack) has worked like a charm for years, but of course it wasn't a complete kit by any means. My manifold has never broken, but I did blow the first turbo (I wasn't running an oil restrictor) I bought another one off ebay for $120. It comes down to how ghetto you want your rig to be. Me; I don't care how ghetto the setup was long as it scoots. Of course if I was made of money I would have had a nice custom setup made. Then again; if I was made of money, I probably wouldn't be turboing a D-series anyway.

P.S. I doubt the kit in the original link above would crack, it appears to be a simple but cast unit, similiar to the old Drag style manifolds. Rather than the crappy tubular stainless manifold that I have.
