Don't some diesel engine have electric WAI? If so, find one of those in a junkyard. It's designed for under hood use.

Some of the small car guys have proven they don't get their best milage till after 20 or 30 miles of driving, well after the coolant is up to temperature, the oil takes a while to warm up.
Cummins engines use an electric grid heater for starting and to smooth out cold start roughness and reduce unburn fuel leaving the exhaust.
That is why I have intake heaters in my diesel.
I believe Cummins has stuck with the electric grid heater. Ford and GM use a heater coil in their engines for smoothing out cold start roughness last time I checked.
