jwtaylor Posted March 17, 2014 Share #14 Posted March 17, 2014 The latter 5 speed (82-83) also has a reverse lock out located on the drivers side and a few inches in front of the shifter. It looks like a diamond shaped plate with rounded corners.

Tirnipgreen Posted July 30, 2023 Share #15 Posted July 30, 2023 So what would be the best rear end ratio (R180) to mate with a "close-ratio" zx transmission...?

kickstand80 Posted July 31, 2023 Share #16 Posted July 31, 2023 Do want to drag race the 1/8 mile, or do you want top end/low rpm at hi way speed Link to comment https://www.classiczcars.com/topic/48761-5-speed-manual-transmission-identification/?page=2#findComment-655552 Share on other sites More sharing options...
Tirnipgreen Posted July 31, 2023 Share #17 Posted July 31, 2023 No drag racing, but better performance on twisty mountain roads...

Yarb Posted August 1, 2023 Share #18 Posted August 1, 2023 3:73 or 3:90 ratio. Not sure what the ratio availability is for the r180.

dutchzcarguy Posted August 1, 2023 Share #19 Posted August 1, 2023 (edited) John means 1: 3,37 not 3,73.. Most R180 are 1:3,364 for the 4 speed. over here we have 1:3.9 for the orig 5 speed 240z box.. for rally there was the 1:4,11 ratio.. my experience is when you install a orig 240z euro 5 speed you need to use the 1:3,9 ratio diff. I don't know if the 280zx 5 speed has much different gears but i guess that there is not much difference so a 1:3,36 diff can give you a bit of a "long" first gear that eats your clutch plate aftyer some time. Also a 1: 3,9 gives shorter gears and more torque. A 1:3,36 gives more top speed. On 8/1/2023 at 1:56 AM, Tirnipgreen said: No drag racing, but better performance on twisty mountain roads... So the answer is i think get yourself a 1: 3,9 diff.. i believe there is also a 1:3,6 and the 1:4,11. It would not surprise me if a 240sx or other nissan diff also would fit.

Patcon Posted August 1, 2023 Share #20 Posted August 1, 2023 I replied in your ad, but why an R180 over an R200? Link to comment https://www.classiczcars.com/topic/48761-5-speed-manual-transmission-identification/?page=2#findComment-655578 Share on other sites More sharing options...
Terrapin Z Posted August 1, 2023 Share #21 Posted August 1, 2023 A maxima had an open 3:70 R180, that's what I put behind my 83zx 5sp. A 720 truck had a front R180 in open 3:90 a 4:11, and a 4:38 even a 4:62 if you can find it. The 240z had the 3:36 for the 4sp and a 3:54 for the automatic.

Tirnipgreen Posted August 1, 2023 Share #22 Posted August 1, 2023 Question...what is meant by an "open" differential. 3:70 i probably what I am looking for as long as it is a "plug and play" unit as I am really not up for an modifications to my current setup.

Thanks, Terrapin...! That means you get one burnout instead of two when you dump the clutch. 2 Link to comment https://www.classiczcars.com/topic/48761-5-speed-manual-transmission-identification/?page=2#findComment-655587 Share on other sites More sharing options...
