Well the 4.0 in the Jeeps was actually a straight 6 so it's not the same.LebanonsFinest said:its not a rumor...they are going to do it. the dodge nitro is going to have that very 4.0L...and its not the same one theyve used in the cherokee sports and wranglers for years...i think they actually discontinued that 4.0L after discontinuing the cherokee sport back in 01...so...its happening . research it, and youll be very happy with the specs. i was when i read the article about the nitro. ill take a look see and try to find it.
