Daphur280 Posted September 14, 2009 Share Posted September 14, 2009 I need the speedo gear from an '83 turbo 5spd, I dont think my transmission is a T-5 Borg Warner though, I think this is the exact one. here Quote Link to comment Share on other sites More sharing options...
Daphur280 Posted September 14, 2009 Author Share Posted September 14, 2009 this is the trans i have, not exact one in pic but same minus the "NMCA 28" on the side (my cam chord is broken so I cant take pics) Quote Link to comment Share on other sites More sharing options...
MikeBZ Posted September 14, 2009 Share Posted September 14, 2009 the turbo zx has a 3.54 rear end and you would need a black 17 tooth speedo gear. That one is a 18 tooth for a 3.70 ratio. (I took that photo) Quote Link to comment Share on other sites More sharing options...
Daphur280 Posted September 14, 2009 Author Share Posted September 14, 2009 so the speedo gear would have to match what rear end i have? cos this is going into a 73 240z w/ r180 rear end, would I need to use the speedo gear in my 4 speed then?

MikeBZ Posted September 14, 2009 Share Posted September 14, 2009 Yeah you match the gear to the rear end ratio. If its a stock 240z rear end you probably have 3:36 or somewhere in that ball park. Take the speedo gear from the 4 speed you removed and install it on the 5 speed. Here are the speedo gears and corresponding rear ratio's YELLOW is the 16 tooth for the 3.36 BLACK is the 17 tooth for the 3.54 BLUE is the 18 tooth for the 3.70 WHITE is the 19 tooth for the 3.90 RED is the 20 tooth for the 4.11 PURPLE is the 21 tooth for the 4.38 Quote Link to comment Share on other sites More sharing options...
Daphur280 Posted September 15, 2009 Author Share Posted September 15, 2009 and taking the gear from the 4 speed and putting into the 5speed wont mash or chew the gears right? Quote Link to comment Share on other sites More sharing options...
