Doug71zt Posted February 16, 2007 Share Posted February 16, 2007 What year is your Z31? If it is a 87 or newer turbo manual, you can use your original tranny with a RB front housing bolted on. Then you could use your mechanical speedo with a cable drive. The VSS - Vehicle Speed Sensor will come out of your transmission and you can install a regular speedo drive gear in the hole. Otherwise, most of the RB transmissions use an integrated VSS in the transmission, might be a bit harder to convert over to mechanical drive.

rb26z31 Posted February 16, 2007 Author Share Posted February 16, 2007 yeah its an 87, the car is totally stripped, I dont have the motor anymore, so I should probably send the mechanical one back and get the electric one...I appreciate your help..

Racinjitter Posted February 17, 2007 Share Posted February 17, 2007 Was your z31 a turbo? Quote Link to comment Share on other sites More sharing options...
rb26z31 Posted February 17, 2007 Author Share Posted February 17, 2007 87 n/a Quote Link to comment Share on other sites More sharing options...
Racinjitter Posted February 17, 2007 Share Posted February 17, 2007 another thing I forgot to ask is.... Do you have a digital dash? If so you still can use the guage. You would need the longer speedo cable though and re-locate the vss located on the shock tower. Quote Link to comment Share on other sites More sharing options...
rb26z31 Posted February 18, 2007 Author Share Posted February 18, 2007 no it has the analog, I am doing to full custom cluster, I want to use the stock cluster and put the autometer gauges in it, but the depth on the cluster in only like 2 1/2" so it will not work because of the speedo and tach is 3", I want to use the stock one so I can still have my turn signals and warning gauges on the bottom of the cluster, but I will figure something else out...

Racinjitter Posted February 20, 2007 Share Posted February 20, 2007 I knew I could find an example for a guage swap. He can make one for you. He has turn signals and everything.
