When I went home over the weekend, I randomly found one of the last turbos I rebuilt....years ago. It is a Holset HY35W (basically a hybrid T3/T4 version of the HX35, used commonly on Cummins diesels). I had originally intended it to be connected to an F22A (A simple, older SOHC Honda engine with an 8.8:1 static compression ratio).
Maybe I'll use it for a project in the future, so I brought it back up from Knoxville.
Just for fun, I thought about putting it on the 200tdi. It would require an exhaust manifold with a T3 output flange and the bonnet would need a cutout. The middle of its efficiency island is 2.5 bar, so assuming the 200tdi could even spool it, that would be roughly 220-230hp.
Max airflow in lb/min is around 560 lb/min so it's not airflow limited.
But in the end, the 200tdi has problems spooling a t2-frame exhaust wheel, let alone a t3 frame exhaust wheel. Probably very little boost coming in very, very late in the rev range. Even if by some sorcery it could spin the wheel, I doubt the bottom end could handle it.
But sometimes it's fun to just think about these things
