You should buy the exhaust heat recovery system (EHRS) off a gen 3 prius and install it on your diesel.

They are pretty much worthless on pick and pull Priuses so i assume you might pay $50 to cut it out and take it.

If I understand correctly the EHRS is part of the warm up cycle on the Prius until it hits 150F and then it goes to normal and the EHRS cuts out.
