Jersey Posted April 26, 2005 Share Posted April 26, 2005 I just picked up a Nissan unit that is suppose to be out of an '82-'83ZX (it does have the long shifter ears) but before i put it in tonight, i went and checked the ratios for the heck of it. I may be doing it wrong (hopefully) but here's the way i did it - i put a clutch disk on the input shaft and marked a line on it which i always started top dead center, and marked the driveshaft TDC as well. Here's what i got... 1st gear, the clutch disk rotated about 3.3 revolutions to 1 driveshaft rev 2nd, a little over 2 times 3rd, about 1.3 times 4th, 1 time 5th, about .8 Now that just about matches the 77-79 5speed ratios: 1st - 3.321 2nd - 2.077 3rd - 1.308 4th - 1 5th - .864 I'm hoping someone can tell me that i did it wrong and this really IS an '82-83 so i can just slap it in and get this thing back on the road!!! lol. Here's a pic that might help... Quote Link to comment Share on other sites More sharing options...
