Experiences with 2.5 turbo diesel

I am in the market for a late-80s 110 and have come across a couple of options with a 2.5 turbo diesel. Any experiences with this setup as a daily driver? I have about a 20 mile one-way commute on the interstate and I have read that 55+ mph would be pushing it. Would an engine swap be my only option for highway speeds of 65-70?

If you are talking a 19J you will be disappointed, they are as slow as a NA diesel. 65-70 mph will require a 200Tdi and a transfer case swap.

A good commuter engine is the Mercedes OM617 5 cylinder turbo diesel and it can run on alternate fuels. Kit is a drop in and bolt up.
It will run highway speeds with the 1.6 T-case, but 1.4 gearing is optimal.
Easily pulls 70MPH on the flat.
The only reason for this post, a member has cold feet on their conversion and has a good engine as well.
I could put you in touch with the member with kit and good engine if you PM me.
