RB20/25/26 knock sensors are all the same.

I'm after a pair also. :S

How are yours playing up? My original set wouldn't read any higher than 1 knock on the pfc.

This other set I have in won't read higher than ~14.

I've put the multimeter on to them and they have gone open circuit? i think. Constantly reading 13-14volts.

one was completely melted & the other got lost during a year long rebuild. I thought the best way to test them is to tap the block lightly with a hammer and u should be able to hear the timing retard.

If you have the engine manual you can get a rough idea if they are working as there's a small test you can perform with a multimeter.

Tapping the block may not work as the knock sensors only hear between 2 frequency's.

Apart from that.. You have a powerfc with a knock readout. Let us know if the block tap works. :D

Just found out through a guy who imports the sensors new that rb20/25 sensors are heaps defferent from rb26. the 20/25 ones come straight out with round green plug on the end and the 26 ones are round with a bolt through the middle and a square 2 pin plug coming off at 45 degrees. I think the 26 ones are the same as sr20.

If your after the 20/25 ones i know someone with a couple on a dead motor.

I'll thank a couple of different wreckers for that incorrect information. :rofl:

Cheers for the heads up.

How much can you get the new sensors for? I know the sensors you are talking of as I've seen them on a lot of the newer nissans and sr20dets.

The 90's maxima's run them also. BMW's almost everything. :)

So I have 4 knock sensors to suit an rb20/25. :S

I can get the RB26 ones through nissan trade at $300 and aftermarket for 250. Rang nissan and they reckon the part no's for sr20 ones is different to rb26 but i found some sr ones at a wrecker for 45 ea and they look identical. gonna put them in and get this thing running at last. yeah maxima's also run them as well as a few other nissans i cant think of right now.

    • Thanks mate 👍 The car was brought into the UK by a USAF mechanic until he was stationed back to the US, one owner later I bought her back in 2009. Luckily the only corrosion was on the sill seams, so once taken back to metal and treated and sealed all ok, I then undersealed the car myself and check yearly and treat any corrosion which to be honest is zero. She's garaged most of the time and hardly ever driven in the rain, but as you say most are rotten unfortunately, I was lucky in finding her as she was and still is in excellent condition.  
    • Stunning car.  Looks amazing!  You're in the UK?  How the hell do you stop your car rotting away beneath you?  British cars are the WORST I've ever seen in regards to rust.  Some of the cars SR Autobody have done are borderbeyond saving.
    • not a date code? or a foundry code? 
    • I have up to date pics of the engine build and turbo conversion over on my instagram @skpro_jects if you want to take a deeper look.   Basically the exhaust manifold is straight bolt on and the ports match (they arent any smaller than a 25 or 26 head).    the intake ports are different shape so the 20/25det manifold will bolt up but wont match properly or seal. You will need to port match using the 25det gasket as a stencil. Personally i ran the entire stock 20neo intake setup and have configured the swirl valves and torque valve to work based on my custom parameters to help with off boost response and spool. But this is using a standalone aem v2 ecu. The stock 20det ecu wont be able to control them.     
    • Hi. a little later but if the topic is here. So...the exhaust is the same and you can use 25/Turbo or any aftermarket? What about intake side? Is it too "plug n play" or? (i do not remember for 100% but i think that one intake to head gasket was little bit different than on the RB25 - i bought gasket kit way back) I know that even if it "plug" those butterfly swirls would cause ECU to be confused or?   Just asking for the info 🙂 and of course the RB25 things are easier to come by
