Adding a turbo to an OM617.912?
Hi,
I realize that the accepted wisdom is "go find an OM617.952" Be that as it may, what's required to retrofit a .952 turbo unit (I don't know if it's KKK vs. Garrett) onto a .912? Do I need a .952 exhaust manifold as well? Other parts? Would any manifolds from models other than a w123 300D be appropriate?
Thanks for the help. It's for a project I'm evaluating. Obviously, if I had access to both cars already, I could answer some of these questions myself.

In other words, the only reusable components are the valve cover, cylinder head, injector lines and intake valves.

Thank you for the info. I eventually found a similar response on another forum; first three digits notwithstanding, there's a lot of difference in these engines. I'd originally thought they were all the same, and bulletproof, as there are several stories of .952 HP increases of 50% with no ill effect, but I guess the non turbo engines weren't built to the same specs.
The good news is I've acquired a 1981 300SD, built for the job.
