Not an expert on the turbo’s yet, but I intend to turbo a CD175 at some point this year after I have finished a couple of other projects I have going.
I am going to run an external oil pump using oil from the engine sump, I will use an oil cooler but I doubt you would need one on an engine as heavy as a KZ.
Exhausts are easy, I made my front pipes out of these (or similar)
I would also fit one of these because a KZ750 engine is not designed to rev (or make more than about 60 hp)
Good luck with it, I will be well interested to see how it goes
