I have searched and no one has posted results except one person who said that they are not sure that they put theres in the right spot. I need to know where to put this thing. I know that we share pretty much of the same layout as the 300zx but there are differences in where the bolts are on the upper intake plenum. which makes all those write ups kind of useless. Is there anyone who has done it solely on the J30, and pics would be a God send. I really need to get this sensor on my car, i am going thru way to much gas. And the hesitation is getting dangerous in traffic.

Well, first of all, i have no experience and no idea where to relocate your knock sensor. I just want to give you my opinion on this subject. Nissan put the knock sensor right on top of the engine block for a good reason, to listen to the knocking inside the combustion cambers when it happen, if you are going to put it some where else, how would you know it will still do the job it was supposed to, all it will give you is some false sense of security, if i have only two choices, either use a resistor to bypass the signal, or relocation. I would choose the first one. At least you are aware of the problem and pay more attention to the engine. I know it would be a pain and costly to get the knock sensor replace, but what choices do we have.

I am also in need of a timing belt, well since i have to replace my Knock Sensor as well, does anyone think that doing these two jobs at the same time would be a good idea? I mean it wouldnt make things to complicated would it? I am not a rookie when it comes to cars but im no pro either.

You still have to remove the intake manifold, both the upper plemun AND lower plenum so you're still looking at a bunch of labor.

How is bypassing the ks altogether better than having one that is relocated and still doing it's job albiet not exactly were it should be?

The big runners that look like fingers interlocked and going down the to engine is the upper plenum.

It's a real pain to take off.

Once you get that off you can see the lower plenum.

It is alo a pain to take off.

If you can't find the intake manifold then you have, well, nevermind.....

Do you know where the air filter is? Follow the air path from the air filter. Once you get to the metal part past the plastic tubes, that is the intake manifold and that part of it is the UPPER intake manifold plenum.

The lower intake plenum is not visable until you remove the upper portion.

I read this & was trying to figure out what 3 parts you were talking about. I have taken my intake off twice & there was no intake, upper & lower plenum. Just an intake that some refer to as a plenum. Here's a couple pictures of my engine & parts when I replaced the EGR tubes in Nov 2006:

It's not 3 parts and I didn't say it was three parts. I said that you have to remove the intake manifold which consists of 2 parts, the upper and the lower.

The 1st picture in your other post shows the upper plenum removed. The lower plenum, which is what the upper plenum attaches to, still has to come off to get to the stock knock sensor location.

Hello people, we are suppose to be finding a relocation spot for those (like myself) whom can't afford to have a dealer do it and wouldn't dare take that much stuff off, at least not until i use some vacation time.

thank you sir, i did relocate mines and the car is running beautifully again and the gas milage is also back to normal P.S. The setup on the Z is a tad different from our J but i was able to put my sensor in the same place.
