1984 Maxima 5-speed Differentia Gearing

[dhayes5]

Anyone know what the gear ratio is for a 1984 Maxima 5-speed? The not so local bone yard has an R200 from one but before I ride 1-1/2 hours to see it I would like to know the ratio.

I am looking for a reasonable R200 either 3.90 or 4.11 to put into my '72 240. I am in Raleigh NC if anyone in the area has one they wish to part with.

I'm not sure what diff was used in the Maxima. I have a chart here that lists the Maxima automatic as having a 3.36 R-180 rear and the manual as having a 3.54 R-180. I'm not sure if they offered an R-200 in the Maxima in the later models, they may have changed over later when they discontinued using the R-180 in the Z series. Of course, there is the possibility that the chart I have is incorrect also.

I would be surprised if they used anything lower than a 3.70 or 3.54 in the Maxima as it was not as sports oriented as it was intended to be. It was more of a sporty touring model so it would be my opinion that it would have a higher gear than what you are looking for in either an R-180 or an R-200.

If you can, I believe you would have an easier time finding an R-180 from a 720 4x4 truck in the gear ratio you want.

1/83-6/83 720 4x4 had a 3.90 R-180

6/83-12/85 720 4x4 had a 4.11 R-180 as did the Non turbo 200sx 84-88

R-180 will hold up to anything you can do to an L series engine, however if you are planning a V-8 conversion you do need the R-200 for durability. R-200 is much heavier and will require suspension crossmember and mustache bar as well as diff mounts to be changed to fit.
