MazterDizazter Posted February 14, 2008 Share Posted February 14, 2008 Hey all, I am interested in swapping a manual Z32 transmission into my S30. I've tried searching for the gear ratios for the transmissions but haven't had much luck. I guess I'm trying to find the one with the tallest gears since I'm aiming for top speed (obviously the differential/final drive ratio will come into play here; I think I have an R200 in my car but I haven't cracked the pumpkin open to check. All I know is that the previous owner installed an LSD). Is there a list somewhere that shows the ratios of the different transmissions, between n/a and turbo, and if there were any differences between the years?

MazterDizazter Posted February 16, 2008 Author Share Posted February 16, 2008 Really just looking for the gear ratios, or at least the transmission codes so I can look them up. Quote Link to comment Share on other sites More sharing options...
mtcookson Posted February 19, 2008 Share Posted February 19, 2008 Z32 5-speed: 1st - 3.214 2nd - 1.925 3rd - 1.302 4th - 1.000 5th - .752 Twin Turbo R230 differential - 3.692:1 NA differential - 4.08:1 90-96 Q45 R200 - 3.538:1 For top speed another option would be the Nissan Armada R230 differential options (this R230 has even larger flange axles and axles compared to the 300ZX from what I've seen): 3.36:1 2.94:1 Excellent site for calculating gear ratios and such - http://www.geocities.com/z_design_studio/transmission_300zx_tt.html Quote Link to comment Share on other sites More sharing options...
