Bolt up to what? You'll need a lot of other parts beside just the turbo. Exhaust manifold and intercooler to mention two biggies, but a lot more on top of that!
Mike, I think this chap was just talking about the turbine itself I believe, and it's not relative to the type of block. A turbine is a turbine. They come in different shapes and sizes but as long as you have a manifold and all the other junk than they all work fine.
