I did not get much help or input on the Nissan consideration in this pretty much dead area of TDR, so maybe I will consider another idea, one I would rather do anyway. I have for a LONG time wanted to put a diesel in a late model Wrangler, with a manual transmission. I would prefer a "P-pump" 3. 9 Cummins, but would also consider the 2. 8 like what is in my Liberty. Any thoughts? Suggestions on where to get a donor vehicle and a "P-pump" 3. 9 or a 2. 8 VM "CRD" engine that a manual transmission will go behind?
