Nicely done.
I had a 903 in my coach, same turbo problem, a replacement ST50 made it better but I developed injector leakage and needed valve work.
I decided to modernize and swap it with a takeout 8.3 and 6 speed Allison.
If you get to needing a major overhaul, an 8.3 with a side radiator is a good option; same hp, more torque, and better mpg.
My 903 went to a tractor puller in PA, he converted it to methanol and pumped 2000hp from it.
