Pete84 Posted March 19, 2007 Share Posted March 19, 2007 What is your rear diff ratio / model? Very good mileage!!! Quote Link to comment Share on other sites More sharing options...
240Z_Master Posted March 19, 2007 Share Posted March 19, 2007 I was gonna say, if I did the same trip on my 4.11 I wouldn't be so lucky, but maybe!? Quote Link to comment Share on other sites More sharing options...
ZDrifter Posted March 19, 2007 Author Share Posted March 19, 2007 Not sure of the diff ratio.....Dont know how to exactly find out but my car is a 1978 Datsun 280z standard R200 nothing changed. Built in April of '78. Quote Link to comment Share on other sites More sharing options...
Cal Poly Zmanaustin Posted March 19, 2007 Share Posted March 19, 2007 78' stock rear diff should be 3.54 unless I am mistaken. Quote Link to comment Share on other sites More sharing options...
240Z_Master Posted March 19, 2007 Share Posted March 19, 2007 78' stock rear diff should be 3.54 unless I am mistaken. Sounds about right... no wonder he got 30+ MPG, haha. Quote Link to comment Share on other sites More sharing options...
ZDrifter Posted March 19, 2007 Author Share Posted March 19, 2007 Yea..Im liking it now...but after mods it will go down...I was cruising going 75mph at 3,000rpm. By the way I Like the new pic of the car 240z master! The mileage wasnt the same coming back tho, hills took over haha, but its nice to hit the hills in 5th gear and easily pass people without shifting down.
