Im considering one of three things for my RB20 install.
---Installing Speedo and tach from a RB25
or
---Installing a Stewart Warner Speedo and tach that I picked up real cheap
or
---Stay with the mechanical speedo and convert to a skyline Tach
Now I understand that the RB tranny runs a mechanical Speedo so I will need to generate a pulse for the electronic speedo to work. I have searched around and have found that Dakota Digital makes this ....

As I see it, to make the SW speedo work I ask DD to make an output connector that connects to the RB20 tranny. Wire the pulse generator to the speedo and calibrate it. In all likelihood over simplified but more or less.
The RB25 speedo may be another matter...it may work on a different pulse and will unlikely have calibration capabilities.
I think I prefer the OEM look over the SW pieces but the SW may be easier with fewer problems.
Has anyone used this device? Am I on the right track? What do you think I should do?
