1. Where should I start looking for a knock sensor?

2. Is there anything in particular I should be looking out for?

3. What sort of prices should I be paying?

 

Thanks.

try one of the traders on here nissan want £160 just for the sensor. you should also change the connetor coming from the sensor to the loom

I am about to show my ignorance.

I didn't know the Zed had a knock sensor as standard!

 

I was thinking that it would be sensible to get an aftermarket sensor so that I would know if there was any dangerous noises coming from the block before, during and after increasing boost.

 

Is the stock sensor any good?

Does it just put the car in safety boost when it detects a problem?

 

Sorry for all the questions, I am a bit naive...

the knock sensor listens for detonation then backs the timing off (i think), some people by-pass the sensor because of the work involved to replace. but if your like me and cant tell when the car dets i wouldn't do this as it can wreck your engine

but it only works up to 3000 rpm so chances are you'll still wreck your engine!

Normally starts when you are running higher than normal boost and over 3000rpm + crappy fuel + bad mapping (chip).

I went aftermarket and bought a KnockLink+Bosch sensor which is a good piece of kit: http://www.thor-racing.co.uk/Knock_Link-LNK_KNK_LNK.asp

Originally modded it by removing the cover and fitting it behind an ally plate with the lights showing but it's now being moved into the centre of the Speedo cluster so it's directly in line of sight.

Yip speak to Nod at Thor, highly recommend the Knock-link.

Great. That is exactly the sort of thing I am looking for.

 

Not only will it pick up detonation but it would also notify you about other unnatural noises coming from the engine block.

 

SO - The knock sensor that comes as stock on the Zed, is this what most people call the Det sensor?

 

Also, if the stock knock sensor only works up until 3000rpm I presume it cannot be used with the KnockLink?

Yes and yes :)

I got my Link and sensor from DPMotorsport: http://www.dpmotorsport.com/parts/knocklink/home.htm

Thanks Leigh, I think I will go for that setup too.

Ohh, I need a payrise!
