s13 with an rb25 gearbox speedo reading - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I have a euro spec s13 that has the CA dash clocks fitted. it has a VVT engine with a RB25 gearbox. with the RB speed sensor connected the speedo reads roughly half actual speed and so does the trip meter.

most people over here in England either just run with the speedo disconnected or use a Dakota digital box, I don't want to use the Dakota box as I think they are rubbish.

what do you guys do to get your speedo's to work correctly? or do your KA clocks just work with the RB gearbox?

searching around suggests that a none turbo z32 speed sensor with the r33 gear fitted should work, but then some people say it don't. some people also say you can fit 180sx clocks and strip them down and adjust a potentiometer that's in the rear.
