zyewdall Posted July 9, 2008 Share Posted July 9, 2008 Interesting bit of information I found on the wikipedia page for justy's 5MT: 1st 3.071 2nd 1.695 3rd 1.137 4th .823 5th .675, Rev 3.461 Final 4.437 4WD: 1st 3.071 2nd 1.695 3rd 1.137 4th .771 5th. 631, Rev 3.461 Final 5.200 The final drive ratio for the 4wd ones is particularly interesting.... 5.2? That makes first gear an overall ratio of 15.96, running 175/70/R13's. This is probably about the same ground ratio, or slighly lower, as my mazda pickup truck which has 4.4 1st gear, and 4.1 diffs -- 18 overall, running 215/75/R15's. Of course, the truck also has a 2:1 low range, for 36:1 in low range. But comparing it to an EA81 or EA82 http://www.ultimatesubaru.org/80s/mick/gear-ratios.htm the overall 1st gear ratio for that is only 14.18 for the EA81's, and 13.82 for the EA82's (standard 4wd MT's). So... the justy is actually geared a bit better than the EA81/EA82 for 1st gear... probably to compensate for the lack of torque from the little three cylinder engine, I imagine. It does feel like it's geared really low compared to my EA82... 1st gear revs up to 4500rpm almost immediately after letting the clutch out it's so low, and 55 or 60 on the highway is almost 3500rpm it seems, whereas the EA82 will do 70-75ish at that rpm. Low range is 20.7 and 22, for the EA81's and EA82's, respectively, so they are definitely better there for offroading. But, I was impressed with how low of gearing the justy has without even having low range. 1st gear on the old EA71 from 1979 is actually just about the same as the justy too.
