Rb25det Knock Sensors Question

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

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

      Thanks. Yeah I realised that there's no way I'd be able to cover the holes with the filler, it would just fall through. Thanks again @GTSBoy!

      That was the reason I asked. If you were going to be fully bodge spec, then that type of filler is the extreme bodge way to fill a large gap. But seeing as you're going to use glass sheet, I would only use that fibre reinforced filler if there are places that need a "bit more" after you've finished laying in the sheet. Which, ideally, you wouldn't. You might use a blob of it underneath the sheet, if you need to provide some support from under to keep the level of your sheet repair up as high as it needs to be, to minimise the amount of filler you need on top. Even though you're going bodge spec here, using glass instead of metal, the same rules apply wrt not having half inch deep filler on the top of the repair. Thick filler always ends up shitting the bed earlier than thin filler.

      Welcome to SAU, looks like you've picked up a nice one! Any plans to spend more money that you have on it until you hate it?

      Also I cut away the top metal that was bent as there's no way I could have gotten it level and the rust stopped. I can also see clean metal under the windscreen. So it looks like this is the extent of it. The lower metal here is also strong.

      Is this ok and then I don't need to patch the holes? Or is it not as good as separate fibreglass repair as well?  https://www.supercheapauto.com.au/p/septone-septone-glass-fibre-filler---500g/3151.html#q=Filler&lang=en_AU&vid=itBd4yPRKxscpBbIMOhvMg%3D%3D&start=10
