Hi guys. This is offtopic, but I hope someone can help me.

We've got an international TD25C dozer with the wrong turbo. The original should be a Schwitzer 4MD-755, the one on there now is a Schwitzer 4LF754.

Does anyone have any catalogues or other info showing the difference between these two turbos? Functionally the 4LF754 is too big, it won't boost enough so the dozer smokes.
I'm hoping to find that like most turbos, there's a smaller A/R exhaust housing out there. But info is hard to find.
