If it has only a reverse lamp switch it's consistent with the '80-'83 non turbo 280zx 5 speed. It's also consistent with the 80-'84 810/Maxima.

 

If you want to know for sure place in first gear and turn the input shaft 10 times.

 

If it's a 280zx, the output spline should turn 3.26 or almost 3 1/3 times.

If a Maxima, it will turn 3 times

zx wide ratio?

 

The first year zx, the '79,  was a mid ratio just like the Maxima. The '80-'83 none turbo were a close ratio. The 5 speed option in the late 280z were also mid ratio. Earlier 280z with 4 speeds were mid ratio but the 240z and 260z were a wide ratio 4 speed.

 

Wide ratio (used in some trucks)

 

1st... 3.592

2nd.. 2.246

3rd... 1.415

4th... 1.000

5th... 0.882

 

Mid ratio (used in some trucks and most cars)

 

1st... 3.321

2nd.. 2.077

3rd... 1.308

4th... 1.000

5th... 0.864

 

Close ratio (used only in the later 280zx non turbo cars)

 

1st... 3.064

2nd.. 1.858

3rd... 1.308

4th... 1.000

5th... 0.773 or 0.745

so mike i got the transmission and it is missing the throwout bearing sleeve, how to i know what one to get.. would you have a part #???

 

The collar had absolutely nothing to do with the transmission you use. The collar is intimately related to the clutch and pressure plate that YOU decide to use.

 

So tell me... what pressure plate are you going to run on this engine? If you have a flywheel on that L20B? measure across the clutch disc surface. There are only 3 possible diameters 200mm (7.8") , 225mm (8.8")  and 240mm (9.45").

 

 

Measure across the shiny part of the disc and let me know ...

Yes, don't forget the collar is matched to the PP not the transmission.

So if I just keep my clutch and flywheel then i should take the clutch collar off the transmission that's in my car now and put it on the 280zx trans with a new throw out bearing?

 

Also I will need to shorten my driveshaft 5 inches correct??

If you have a sedan, the drive shaft needs to be shortened from the stock 42 9/16" down to 37 3/8"

 

If you have a wagon,  the drive shaft needs to be shortened from the stock 48 7/8" down to 43 11/16"

 

 

 

Alternatively, if you stand the transmissions up and accurately measure the difference in their lengths it should be 31.5" - 26" = 5.5" plus or minus a few 16ths.
