Hey guys,
I've recently manual swapped my RB25DE Skyline and have put a RB20E gearbox in.
The RB20E gearbox is out of a series 1 R33 and my R33 is a series 2.
Since doing the swap, I've noticed my speedo is reading just over double and the odometer is rolling the ks over faster. I have kept the original auto cluster in for now untill I can source a manual one.
Could this be because of the transducer/speedo sensor? If so, which one would I need to get to get an accurate speed? An RB20E as this is what the gearbox is, or a RB25DE?
Or could the issue be something else entirely?
Cheers
