Guest Anonymous Posted July 26, 2001 Share Posted July 26, 2001 Heya... I was just wondering which diff is in the '74 260Z.....I believe it's a non-2+2, because I *think* the 2+2 has the R200.....I'm hoping this one does too Thanks!

74_5.0L_Z Posted July 27, 2001 Share Posted July 27, 2001 All 260Zs came with R180 differentials. The coupes have 3.36 to 1 gear ratios, and I think the 2+2 models had 3.70 to 1 gears. The 240/260 is easily upgraded to the R200. The easy way to identify an R180 versus an R200 is to look where the axle enters the differential. If the axle enters the side of the differential case through a bolt-on flange then it is an R180. Quote Link to comment Share on other sites More sharing options...
