Rb25det Knock Sensors Question

[Sparkys]

I have an R32 with an RB25DET Neo, bought it in pieces cheap and I'm currently putting it back together. I haven't got my head around what wiring has been done and what 25 or 20 parts were used in the process yet, so I have a question.

Are the knock sensors from the RB25 Neo the same as the knock sensors from an RB20? The two knock sensor plugs that are currently in use in the engine bay are apparently from the RB20 and they don't quite fit the RB25 sensors. If they don't quite fit it made me concerned that the signal being sent to the ECU could also be different. Anyone shed some light on this for me?

Cheers, Sparky

If they're anything like my neo knock sensors they're shagged and telling the ECU that grenades are in the engine (even with the engine not running)

Both microphones so I doubt it ... Some people often replace them with better items. I would replace them due to age but I wouldnt be suprised if even the rb25 neo used the same ones.

they are quite similar, although the plugs are different. Ya should be able to just swap the rb20 sensors over to the rb25 block, then just use the rb20 wiring loom to connect to the sensors

Cheers guys.
