RB25DET S14, tach and speedo not working...

[underground]

Well I am working on a customers RB25DET S14 Silvia, and the tach and speedo are not working....

Anybody wanna tell me where the speed sensor is on the R33 GTS-T tranny?

Also, can you give me some guidance on how to wire this all up.?

Thanks...

I have an RB25 in my 180 (originally SR), and the SR speedo will read exactly half of road speed, ie, when you are going 80 speedo says 40. Others with RB conversions have said the same thing. The Tacho is all over the place, going slowly up to about 2500 then jumping straight to over 5000 and then winds right off the clock. You need to get a tacho from an R33 (or aftermarket) to solve this.

Hope this helps a bit....
