I bought an 08 Patrol 3.0 ute with 45km on the clock. The engine is economical but crap to say the least. The 4.2, i could see the fuel guage moving on the test drive so i didnt go in that direction. What are the best options for an engine change? Cummins isf 3.8 or Iveco 3.0 htp, do they fit? Please help, nissan engines are annoying! its doesnt deserve nads or aftermarket stuff.
